About 3% of Starlinks Have Failed So Far
https://www.universetoday.com/148514/about-3-of-starlinks-have-failed-so-far/amp/

... To date, the SpaceX has launched over 800 satellites and (as of this summer) is producing them at a rate of about 120 a month. There are even plans to have a constellation of 42,000 satellites in orbit before the decade is out.

However, there have been some problems along the way as well. Aside from the usual concerns about light pollution and Radio Frequency Interference (RFI), there is also the rate of failure these satellites have experienced. Specifically, about 3% of its satellites have proven to be unresponsive and are no longer maneuvering in orbit – which could prove hazardous to other satellites and spacecraft in orbit.

In order to prevent collisions in orbit, SpaceX equips its satellites with krypton Hall-effect thrusters (ion engines) to raise their orbit, maneuver in space, and deorbit at the end of their lives. However, according to two recent notices SpaceX issued to the Federal Communications Commission (FCC) over the summer (mid-May and late-June), several of their satellites have lost manoeuvring capability since they were deployed.

Unfortunately, the company did not provide enough information to indicate which of their satellites were affected. For this reason, astrophysicist Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics (CfA) and the Chandra X-ray Center presented his own analysis of the satellites’ orbital behaviour to suggest which satellites have failed.

https://www.planet4589.org/space/stats/megacon/starbad.html

Naturally, some level of attrition is inevitable and 3% is relatively low as failure rates go.

But every satellite that is incapable of maneuvering (due to problems with its communications or its propulsion system) creates a collision hazard for other satellites and spacecraft.



Their latest launch took place earlier today (Saturday, Oct. 24th), which effectively brought their constellation to 835. Therefore, A 3% failure rate means that roughly 25 satellites will fail and become part of the growing problem of “space junk.”

... “I would say their failure rate is not egregious. It’s not worse than anybody else’s failure rates. The concern is that even a normal failure rate in such a huge constellation is going to end up with a lot of bad space junk.” - McDowell

... When one takes into account rates of failure and SpaceX’s long-term plans for a “megaconstellation,” the Kessler syndrome naturally rears its ugly head.

Recent filings with the International Telecommunications Union (ITU) show that the company hopes to create a megaconstellation of as many as 42,000 satellites.

In this case, a 3% failure rate works out to 1,260 satellites With a mass of 250 kg (550 lbs) becoming defunct over time. As of February of 2020, according to the ESA’s Space Debris Office (SDO), there are currently 5,500 satellites in orbit of Earth – around 2,300 of which are still operational. That means that a full Starlink megaconstellation would increase the number of non-functioning satellites in orbit by 40%.

The problem of debris and collisions looks even more threatening when you consider the amount of debris in orbit. Beyond non-functioning satellites, the SDO also estimates that there are currently 34 000 objects in orbit measuring more than 10 cm (~4 inches) in diameter, 900 000 objects between 1 cm to 10 cm (0.4 to 4 in), and 128 million objects between 1 mm to 1 cm.
“There are three classes of people: those who see. Those who see when they are shown. Those who do not see.” ― Leonardo da Vinci

Insensible before the wave so soon released by callous fate. Affected most, they understand the least, and understanding, when it comes, invariably arrives too late

About 3% of Starlinks Have Failed So Far
Quote
Unfortunately, the company did not provide enough information to indicate which of their satellites were affected.

Most of the failures appear to be from earlier versions of the Starlinks. There is no basis [except FUD] to extrapolate that percentage to newer and future versions of the satellites.

Quote
To date, SpaceX has launched 773 of the v1.0 satellites, with a half dozen of those being deorbited already and another dozen or so, mainly from the early launches, suffering impairments to their functionality.  Only 14 of the 60 test satellites from the v0.9 launch remain in orbit.
https://www.nasaspaceflight.com/2020/10/spacex-second-starlink-mission-in-week/

12 of 773 is about 1.5% — and these are “impaired,” not non-functional.

Bank doubles its valuation of SpaceX.
In a new report released this week, the investment bank Morgan Stanley says it is raising its "base case enterprise value" of SpaceX from $52 billion to $101 billion. "The pieces are coming together for SpaceX to create an economic and technological flywheel," the report states, citing Starship, Starlink, and reuse. (The report is not online as far as we can tell).

Winner take most? ... In part, the report stated, "It is clear to investors and industry observers that SpaceX's launch cost advantages are being used to accelerate deployment of its LEO broadband network. As the company achieves pole position in LEO, which many believe is a winner take most (if not winner take all) arena."


Russia will no longer talk about the Amur rocket.
A few weeks ago we reported about the country's plans to develop what appeared to be a smaller clone of the Falcon 9 rocket, dubbed Amur. For the first time, the Russian space corporation Roscosmos was embracing a rocket design that incorporated reuse. But now? After digesting the public reaction, Roscosmos says it will no longer share details about the reusable methane rocket "since there are just 70 days left until December 31. If your company is planning a launch in 2020, you have just 10 weeks left!" reports All About Space magazine.

An about-face ... So what is really going on here? Our sense is that Russia's space program has told its citizens for years that Elon Musk and SpaceX are no different from other rocket companies and that his "low-cost" rockets are heavily subsidized by NASA and the US military. Roscosmos also downplayed the benefits of reuse. It is therefore not surprising that public reaction to the proposed Amur rocket was jaded. …

Jonathan McDowell:  The V1.0 sats started with Starlink 1000. And they are production numbers not as-launched sequence numbers, so not all numbers are up.
< 1 week for DOA sats? That seems like a pretty successful debris mitigation path.
Jonathan McDowell:  Yes. It's the ones that fail at operational altitude that you worry about.

Earlier it was thought the U.S. Crew-1 astros would also vote from space, but their launch has been delayed until mid-November, after the election.
This American astronaut voted from space. Here's how she did it
Quote
NASA astronaut Kate Rubins casting her vote from some 200 miles above Earth should be all the motivation you need to make a plan to vote this year.
Rubins, the only American voter not currently on Earth, said she was able to vote from the International Space Station last week.

This isn't the first time Rubins has cast her ballot from space: She voted in 2016 when she was also researching at the space station.

How to vote from space
Astronauts registered to vote in Texas got the right to vote from space in 1997, when Texas lawmakers ruled they could electronically cast their ballot off-planet if they'd be on a spaceflight during the early-voting period or Election Day, according to the Smithsonian's National Air and Space Museum. NASA's Johnson Space Center is located in Houston, so most astronauts are based in the city and registered to vote in Harris County, where Houston is located.

The space-voting process works like this, NASA told CNN last month: The Harris County Clerk's Office uploads a secure electronic ballot to NASA's Johnson Space Center Mission Control Center. NASA astronauts, using specific credentials, access their ballot and cast their vote, which is delivered back to the county clerk's office by email.

Armenian email campaign asks SpaceX not to aid Turkish regime with satellite launch
4:54 PM EDT•October 27, 2020
Quote
SpaceX staff and members of the media have been inundated this morning with emails ostensibly from concerned Armenians around the world, asking the company to cancel a launch contract with the Turkish government. The concerns are valid — and the mass-email method surprisingly effective.

In the form email, received by TechCrunch staff hundreds of times in duplicate and with minor variations, the senders explain that they represent or stand in solidarity with Armenians worldwide, an ethnic and national group that has suffered under the authoritarian rule and regional influence of Turkey’s President, Tayyip Erdogan.

SpaceX is slated to launch the Turkish satellite Turksat-5A in the next month or two, a geostationary communications satellite built by Airbus that will serve a large area of Europe, Asia, and the Middle East. The deal has been on the books for a long time, and SpaceX CEO and founder Elon Musk even traveled to Turkey to meet with Erdogan regarding the satellite in 2017.

To enter into the complexities of the long conflict in which Armenia, Azerbaijan, Turkey, and nearby countries and powers have figured is beyond the scope of this article, but it is hardly controversial to say that there have been serious human rights abuses under Erdogan’s regime and others. The word “genocide” is frequently used.

As the email plea points out, many countries and governments have opted to condemn Turkey’s behavior, and some companies have stopped doing business with the government. Will SpaceX join them?

At this stage — a month before launch, when the payload is likely already locked in — it seems unlikely that SpaceX will return the millions of dollars Turkey has no doubt already paid it, in order to appear more ethical by deplatforming, as it were, the government there.

But the campaign raises a legitimate question that is increasingly faced by new tech-focused companies growing to encompass a global community that is diverse and at times difficult to navigate. Where do companies like SpaceX — or Apple, or Google, or Facebook, or for that matter Airbus — draw the line? Should SpaceX be disinterested and mercenary, simply providing services to anyone who pays? Or are there some governments or people whose money it will not take? …

—- Starlink fail rates
Quote
Jonathan McDowell (@planet4589) 10/29/20, 11:54 AM
I have updated my calculations on Starlink failure rates. The V0.9 prototypes had a 13 percent failure rate. The first 7 V1.0 launches (420 sats) have had a 3 percent failure riate. The next 7 V1.0 launches (with visors; 413 sats) have had a 0.2 percent failure rate so far
    https://twitter.com/planet4589/status/1321842804088279041
~ A large fraction of the latter cohort are still undergoing orbit raising and have only been up for a couple of months, so the failure rate for that group will likely rise a bit over time. Nevertheless it does seem that the reliability of the satellites has noticeably increased.
~ See https://planet4589.org/space/stats/megacon/starbad.html  for a revised table of the number of satellites in each group which have failed.
~ Regular readers will know that I remain concerned about the impact of Starlink and other large constellations on astronomy. But this improved reliability rate is, provisionally, good news for the space debris risk they pose - congrats to @SpaceX for this.
~ Let's see if this encouraging result holds up over the coming months (i.e. that we don't see propulsion failures in the recent group crop in the late stages of orbit raising).
~ One more thing: that 0.2 percent is based on the failure of a single satellite in the most recent 413 Starlinks launched., so there's a bit of an error bar on it! There may be a few other failures already but it takes a longer baseline to be sure they have failed.

< Given the differences in time on orbit among the groups of satellites, I would think that showing the relationship between time on orbit and percentage of failures would be more informative.
Jonathan McDowell: Yes, I haven't had time to do that yet but plan to do so. A fair number of the failures in the earlier group were in the first month or so though.

It's Official: SpaceX Can Bid on $20 Billion FCC Rural Broadband Contract
Oct. 29 marks the opening of bids to provide subsidized broadband internet service -- including from space.
Quote
Americans want fast broadband internet service -- and SpaceX says it can provide it.

In fact, since at least March of this year, SpaceX has been petitioning the Federal Communications Commission (FCC) for permission to compete for money from the Rural Digital Opportunity Fund (RDOF) worth $16 billion initially, and eventually up to $20.4 billion. The FCC plans to choose one or more telecommunications providers to expand rural customer's access to gigabit-speed internet service. Those providers who offer the most attractive prices for the most reliable -- and fastest -- service can expect to win a lot of taxpayer money from the government.

In June, the FCC announced that it will permit SpaceX to compete for part or all of these funds in the fastest, lowest latency tier of service. Earlier this month, the FCC went a step further. Releasing the official list of 386 companies qualified to submit bids to provide low-latency (i.e. low-lag) internet service to rural locations, the FCC named all the usual suspects: 

In an A-to-Z list of 386 approved bidders, the FCC confirmed that Altice can provide broadband internet service, and Verizon Communications, too. Cincinnati Bell, Cox Communications, and Co-op Connections Consortium all made the cut. Ground-based cellular and cable companies galore, in fact, will all be permitted to bid for the most lucrative, low-latency work -- but among satellite broadband internet providers, only Hughes, Viasat, and SpaceX were approved to bid. 

What it means for the satellite companies
Questions remain concerning all three satellite bidders.

Hughes and Viasat, for example, provide their internet service from high-flying geostationary satellites. But at orbital altitudes 22,000 miles from Earth and more, their lag times are likely to be huge -- as much as 500 milliseconds or more, notes SpaceNews.com, versus the sub-100 millisecond lag times that the FCC is looking for. To remedy this deficiency, Hughes has proposed offering service from bankrupt OneWeb's Low Earth Orbit satellites instead. Viasat, meanwhile, may solve the latency problem by creating a new constellation of LEO satellites of its own. 

SpaceX, which has already begun orbiting Starlink satellites at altitudes of less than 400 miles, is promising lag times well within the FCC's threshold for low latency. Granted, SpaceX is only just now getting ready to open Starlink beta testing to the public, but private tests conducted in-house suggest its satellite constellation is already delivering lag times as low as 31 ms. …

It wasn't that long ago that Ariane 6 was targeting the end of 2020 for its first flight. Now it is the second quarter of 2022.

ESA (@esa):
#VegaC and #Ariane6 are being developed by ESA to assure Europe’s independent access to space. The maiden flight for Vega-C is planned to take place in June 2021, that for Ariane 6 for the second quarter of 2022:   ➡️ https://t.co/2QjArrD2dx

Eric Berger:
ESA will ask member states for an additional 230 million euros to pay for Ariane 6 development, above existing budgets. Now targeting 2022 for debut launch of the new rocket.

[ Ariane 6 is roughly comparable in lift capacity to Vulcan or Falcon Heavy]
< If you told me two years ago that Starship had a chance to beat the Ariane, Vulcan, New Glenn, and SLS to orbit I probably would have laughed a little... now? .....

Elon Musk’s SpaceX Says It Will ‘Make Its Own Laws On Mars
https://www.independent.co.uk/life-style/gadgets-and-tech/elon-musk-spacex-mars-laws-starlink-b1396023.html

SpaceX will not recognise international law on Mars, according to the Terms of Service of its Starlink internet project.

Elon Musk’s space company will instead reportedly adhere to a set of “self-governing principles" that will be defined at the time of Martian settlement.

Any future colony created by SpaceX would likely use constellations of Starlink satellites orbiting the planet to provide internet connection to people and machines on the surface.

Users noted that the terms of service within the app state that Starlink services provided to Earth or Moon will be governed in accordance with the laws of the State of California.

Beyond our planet and its satellite, however, the laws and regulations by which it will abide are less clear

... “For services provided on Mars, or in transit to Mars via Starship or other colonization spacecraft, the parties recognize Mars as a free planet and that no Earth-based government has authority or sovereignty over Martian activities,” the document reads, which was included in the Terms of Service of its ambitious Starlink project.

“Accordingly, disputes will be settled through self-governing principles, established in good faith, at the time of Martian settlement.”

---------------------------------------

.... Badges? We ain't got no badges! We don't need no badges! I don't have to show you any stinking badges!

“There are three classes of people: those who see. Those who see when they are shown. Those who do not see.” ― Leonardo da Vinci

Insensible before the wave so soon released by callous fate. Affected most, they understand the least, and understanding, when it comes, invariably arrives too late

How far into flight / landing do you think SN8 will make it for its 15km hop?
https://twitter.com/erdayastronaut/status/1322600671103901697
[Poll at the link]

Chris B - NSF:
A stable bellyflop and a Raptor relight would be a huge win. More than enough data to sort out any subsequent wobbly landing attempt.
However, it's going to be on all of us regulars to set expectations as a preemptive strike against drive-by media "Elon rocket boom" headlines.
Elon Musk:
Stable, controlled descent with body flaps would be great. Transferring propellant feed from main to header tanks & relight would be a major win.
Elon Musk:
But, a RUD right off launch pad is also possible. Fortunately, SN9 is almost ready.
https://twitter.com/elonmusk/status/1322659784210960390
< Are SN8 & SN9 identical or does SN9 have minor tweaks already?
Elon Musk: Minor

< Is the bellyflop the part of the flight that you’re most concerned about? Or the flight in general?
Elon Musk:
Understanding exactly how the body flaps control pitch, yaw & roll during descent, such that the ship is positioned well to relight, flip & land, would be a big win

Everyday Astronaut:
Correct me if I'm wrong, but this is a very novel control scheme, right? I mean controlling aerodynamically purely with drag only while completely perpendicular to the wind stream is something new, correct? Landing on target seems hard to me!
Curious if there's been any sub scale little RC planes or anything tested to make sure that control scheme actually works!?
Elon Musk:
We’ve tested a sub-scale version in a wind tunnel with active aero closing the loop for stability, so it will probably work at scale, but reality tends to bite you on the ass

Thomas Burghardt:
In the event that relight doesn't occur, will SN8 splashdown offshore, or some other plan to terminate the flight?
Elon Musk:
Yeah. Although, if it fails right at the end, some landing pad repair will be needed to fill in the crater.

After month-long stand down, SpaceX ready for fourth GPS III launch

The eastern range is coordinating both this launch and an Atlas V with the NROL-101 mission. NROL-101 scrubbed on Wednesday due to an issue with ground system liquid oxygen valves. That launch is now scheduled for Friday, which is also the backup opportunity for Falcon 9 and GPS-III-SV04.

If Falcon 9 is does not launch on Thursday, which mission can attempt on Friday would depend on the resolution of the Atlas V ground support equipment issue, the cause of Falcon 9’s delay, and the relative priority of the two national security missions.

The potential effects of Hurricane Eta are also in play, with weather at Cape Canaveral forecasted to deteriorate over the weekend. …

News: @NASA has issued an announcement calling for submissions of potential partnerships to visually bring the public along for the ride on the #Artemis II mission.

NASA Seeks New Partners to Help Put All Eyes on Artemis Moon Missions
Quote
NASA is seeking new partners to help the agency tell the story of human exploration at the Moon with the Artemis program in ways that engage, excite, and inspire a worldwide audience. Through the end of this decade, NASA will explore more of the lunar surface than ever before and will establish a sustainable human presence with Artemis in preparation for future human missions to Mars.

The agency has released an Announcement for Proposals calling for submissions of potential partnerships to visually bring the public along for the ride in new ways, starting as early as a trip around the Moon with astronauts on the Artemis II mission, targeted for 2023. Proposals are due by 11:59 p.m. EST, Dec. 11, 2020.

“We’re looking for partners to use advanced technologies, imagery applications and approaches that will go beyond our standard coverage on NASA TV,” said NASA Administrator Jim Bridenstine. “We want to capture the awe of Apollo for a new generation – the Artemis Generation. Just as people were glued to the TV 50 years ago as astronauts took the first steps on the Moon, we want to bring people along in this new era of exploration.”…
https://www.nasa.gov/press-release/nasa-seeks-new-partners-to-help-put-all-eyes-on-artemis-moon-missions

Note: Bridenstine has admitted that he was stunned at the level of interest in SpaceX’s uncrewed Demo-1 mission.  I think he’s missing a big opportunity here by not starting this outreach with the uncrewed Artemis 1.  Unless it’s too late for that, and he sees signs that the public (or Congress) isn’t terribly interested in Artemis, and the purpose of this is to try to drum up support for future missions….

Texas satellite company defends itself against NASA criticisms
Eric Berger - Nov 5, 2020
Quote
The founder of a Texas-based company that wants to put more than 200 very large satellites into low-Earth orbit has pushed back on concerns from NASA that these spacecraft pose an orbital debris threat.

“We’re not a bunch of cowboys launching satellites,” said Abel Avellan, founder of AST & Science, in an interview. "This is a serious, well-funded project."

Each of the satellites will include a large antenna, comprising an area as large as 900 meters squared. However, Avellan said the satellites will fly edge-on, "like a frisbee, but without the spinning." …
https://arstechnica.com/science/2020/11/texas-satellite-company-defends-itself-against-nasa-criticisms/
Astronomy groups might have a few things to say about the potential interference from two hundred satellites each 900-meters-squared in size, facing the earth and directing "ultra-high-power generation" of 100kW, or more, at it....

The commercial crew ship arrived in SpaceX’s hangar near the southern perimeter of 39A on Thursday. SpaceX technicians inside the building will connect the Crew Dragon with a Falcon 9 rocket before rolling the fully-assembled launcher up the ramp to pad 39A this weekend.

The commercial crew capsule is scheduled for launch Nov. 14 at 7:49 p.m. EST (0049 GMT on Nov. 15) with four astronauts aboard. The mission is known as Crew-1, and it will be the first operational flight of SpaceX’s Crew Dragon spacecraft following a 64-day test flight to the space station earlier this year with astronauts Doug Hurley and Bob Behnken.

The Crew Dragon spacecraft for the Crew-1 mission is named “Resilience,” a name that commander Mike Hopkins said he hopes “can be an inspiration for everybody on what’s possible when we work together.” …

SpaceX successfully launched its Falcon 9 mission with the fourth GPSII satellite at 18:24 EST (23:24 UTC) on Thursday, 5 November.

The launch followed a scrub on 2 October, when Falcon 9 aborted two seconds before liftoff. The resulting investigation identified an issue within the gas generators on some first stage engines and prompted several engine swaps across the Falcon 9 fleet and affected multiple upcoming launches. …

Inside SpaceX’s Payload Processing Facility at Vandenberg Air Force Base in California, the U.S.-European Sentinel-6 Michael Freilich ocean-monitoring satellite is being encapsulated in its payload fairing on Nov. 3, 2020. Sentinel-6 is scheduled to launch on Nov. 21, 2020, at 12:17 p.m. EST, atop the SpaceX Falcon 9 rocket from Space Launch Complex 4E at Vandenberg Air Force Base.

A U.S.-European partnership, the Sentinel-6 Michael Freilich spacecraft will begin a five-and-a-half-year prime mission to collect the most accurate data yet on global sea level and how our oceans are rising in response to climate change. The mission will also collect precise data of atmospheric temperature and humidity that will help improve weather forecasts and climate models.

The spacecraft is named after Dr. Michael Freilich, the former director of NASA's Earth Science Division and a tireless advocate for advancing satellite measurements of the ocean. …

SpaceX begins assembling first Starship Super Heavy booster in South Texas
Quote
SpaceX has taken the first unequivocal step towards orbital Starship launches, kicking off assembly of the first Super Heavy booster (first stage) – a necessity for recoverable spaceship missions to Earth orbit and beyond.

Although SpaceX could technically get away with building much smaller booster prototypes to support Starship’s initial orbital test flights, perhaps going as far as simply modifying Starship’s proven tank design, rocketry really doesn’t lend itself to modularity. Be it out of confidence or necessity, SpaceX appears to be moving directly from Starship prototype development to full-scale Super Heavy booster production and testing.

The first conveniently labeled Super Heavy booster rings were spotted around September 22nd. In the six or so weeks since then, SpaceX’s Boca Chica, Texas factory has relentlessly churned out at least as many sections of stacked booster rings – now strewn about the ever-growing campus. No less than seven labeled Super Heavy ring sections have been spotted since the first, equating to fewer than 25 steel rings of the estimated 38-40 needed to complete each booster. …

Pre-flight inspection showed an anomalous reading on a Falcon 9 second stage purge valve.  Rocket was lowered horizontal and the part was replaced, prior to static fire.
SpaceX’s Human Flight Certification is the culmination of ten years of planning, testing, analysis and independent reviews.

Benji Reed, senior director, Human Spaceflight Programs, SpaceX:  Every time I go to the Cape, I spend time in the grove of seven trees memorializing the Challenger crew.  It is our sacred duty, holding the lives of the astronauts in our hands as we transport them into space, provide a lifeboat while they are on the ISS, and bring them safely back to their families.  We’ll only fly when we are ready.  We’ll stop if needed.
Benji Reed:  Over the next 15 months, SpaceX has seven crew and cargo missions for NASA.  Starting with Crew-1, there will be a continuous SpaceX presence on the ISS. Starting with CRS-21, every time we launch a Cargo Dragon, we’ll have two Dragons in space for an extended period of time.

Expect spring and fall crew missions to the ISS.
Kathy Leuders: we want people to celebrate with us, but we don’t want the launch to be a COVID super-spreader event.  Wear a mask and find your six feet of social distance on the beach.

Update: Due to onshore winds and recovery operations, @NASA and @SpaceX are targeting launch of the Crew-1 mission with astronauts to the @Space_Station at 7:27 p.m. EST Sunday, Nov. 15. The first stage booster is planned to be reused to fly astronauts on Crew-2. #LaunchAmerica
https://twitter.com/jimbridenstine/status/1327357510022434816

Per the Prelaunch news conference 7pm ET  Fri Nov 13: delay was caused by heavy seas preventing drone ship from leaving port [via tugboat Finn Falgout] and attaining speed needed to reach landing zone in time. They are now on their way and will be on station in plenty of time for Sunday launch.

Also: not even Elon Musk or Jim Bridenstine are permitted to break exposure protocols that have been in place for years, and begin weeks before a flight, for astronauts and critical launch personnel (including their backups).  After all, this is a long duration mission!

—- Crew-1 launch.  It’s all about the temperatures…
SpaceX Falcon 9 rocket nails first operational NASA astronaut launch [updated]
By Eric Ralph November 15, 2020
Quote
Update: SpaceX has successfully resolved a handful of minor thermal control issues facing the brand new Crew Dragon capsule currently ferrying four astronauts in low Earth orbit (LEO).

As previously noted, shortly after the spacecraft reached orbit, two redundant thermal control system pumps registered pressure spikes, pushing Crew Dragon to use the backup pump. SpaceX was able to resolve that issue, effectively restarting the pumps and confirming healthy operation. Several hours later, the backup pump (“Loop B”) suffered another minor issue but was again returned to healthy operations. Simultaneously, Crew-1 astronauts found themselves stuck at an (admittedly comfortable) cabin temperature of 23C (~73F).

More pressingly, three of four heaters used to warm the propellant fed to Crew Dragon’s small Draco maneuvering and attitude control thrusters were automatically disabled a few hours after liftoff. Essential for most operations in orbit and necessary for Dragon to be allowed to remain docked with the ISS, restoring the functionality of at least one of the three heaters was essential, and SpaceX was thankfully able to restore function to all three by relaxing excessively conservative limits in the spacecraft’s flight software. Thanks to SpaceX’s fast work, Dragon is now in perfect health and ready for two crucial Draco burns at 11:20 am and 12 pm EST (UTC-5) on Monday, November 16th and is still scheduled to arrive at the ISS around 11 pm EST.


Right on schedule, a SpaceX Falcon 9 rocket has successfully lifted off on the company’s operational NASA astronaut launch debut, sending four crew members on their way to the International Space Station (ISS) in a historic moment for commercial spaceflight.

Days prior, NASA and SpaceX completed a multi-day “flight readiness review (FRR),” the results of which made SpaceX the first private company in human history to be qualified by a national space agency for routine astronaut launches. As is now more or less routine, the SpaceX Falcon 9 rocket assigned to NASA’s Crew-1 mission performed flawlessly over the 12 minutes it was involved in the launch, including nominal booster and upper stage performance, a successful booster landing at sea, and a smooth Dragon deployment from Falcon 9’s expendable second stage.

In a small point of concern, Crew Dragon capsule C207 (colloquially named Dragon Resilience by its crew) appeared to suffer a minor hardware or software fault shortly after orbital insertion, offering the first public glimpse behind the scenes as ground teams coordinated with Dragon’s orbiting astronaut crew to diagnose and fix the issue. …

Because of your "in 2 hrs" post, Sig, I watched my first space liftoff ("live", albeit on screen) since John Glenn's first space flight in Friendship 7 on February 20, 1962.  It was scheduled for very early in the morning, and although 'my' (borrowed) alarm clock went off, my dad had to come in and wake me up.  He asked if I really wanted to watch and I did.  (He went back to bed.)  I remember watching the (nighttime) static (I was 5 [edit: I was 6] and didn't read [technically I could read, but I wasn't a reader for another 6 years]), then TV test signal (in black & white) for a very long time before the TV network woke up.  Reading in Wikipedia, I would have sat there watching 'nothing interesting' (static, test signal plus 'delays') for over 2 hours. 

There were no delays yesterday evening (albeit there were problems to be solved, one involving hardware) before Crew Dragon Resilience lifted off.  I doubt I'll be remembering this experience in 59 years.  ::)

I had the good luck to witness 2 shuttle launches; one from Florida and a polar insertion I watched from Connecticut. I also had a part to play regarding crew safety on John Glenn's final flight - Space Shuttle mission STS-95.

I also had all the Mercury and Gemini astronaut trading cards, along with a nearly complete set of Mars Attack cards.

Alas, mom pitched them in the bin.  :'(  Can't imagine why

Yes, the pre-launch cabin pressure leak due to “FOD in the door seal” was a nail-biter, considering that seal has to hold in space not just for the trip up, but for six months, plus the ride home!  :o

And I went to bed last night wondering if they would even get to the ISS, due to the prop line heater problem.  From what I was seeing, if the problem were not resolved, the mission might have to be scrubbed and the capsule would be back on earth by the time I got up.  Whew!

Resilience will be docking to the ISS in about three hours!

Crew-1 Timeline Updates
Chris G - NSF, 11/16/20, 7:26 PM:
Crew Dragon #Resilience is nearing the International Space Station ahead of docking tonight at 23:00 EST (04:00 UTC).
Thomas Burghardt (@TGMetsFan98) breaks down the timeline... and what the parking situation is gonna be like at Station into next year:

Crew Dragon Resilience to expand ISS crew to seven
November 16, 2020
Quote
After a 27.5 hour commute, Resilience and its crew are planned to dock to the International Space Station at approximately 23:00 EST Monday (04:00 UTC on Tuesday), increasing the Station’s crew from three to seven.
The expanded crew on the orbiting laboratory will mean more time for Station maintenance and scientific research.


The CRS-21 Dragon spacecraft will stay at the station for about a month.  Once it departs in early January 2021, the schedule of Boeing’s uncrewed OFT-2 Starliner mission will determine where Crew Dragons Resilience and Endeavour (flying the Crew-2 mission) will need to maneuver, as OFT-2 Starliner will dock at the IDA-2 port.

Presuming OFT-2 is ready to fly prior to Resilience’s departure in April 2021, the Crew-1 astronauts will board Resilience and reposition the spacecraft to the IDA-3 port, after CRS-21 Dragon’s departure.  All Crew-1 members will need to be on board in the unlikely event that an issue prevents Resilience from re-docking to the Station and needs to return to Earth.

In this scenario, assuming no issues during the repositioning, Crew Dragon Endeavour would dock to IDA-2 prior to Resilience’s return to Earth, marking the first Crew Dragon spacecraft to make a second visit to the ISS.  SpaceX will operate a fleet of Crew and Cargo Dragon spacecraft, all flying multiple missions to the ISS for both NASA’s Commercial Crew program and private customers.

SpaceX President Gwynne Shotwell says Crew-1 should be the beginning of a continuous presence of Dragon spacecraft on orbit.

SpaceX lining up two Falcon 9 launches and landings in ten hours
 

By Eric Ralph November 17, 2020
Quote
SpaceX appears to be on track to attempt two separate Falcon 9 launches and landings within the same ten-hour, also marking the company’s 14th Starlink mission this year and first West Coast launch in a year and a half.

After overcoming a range of minor issues, replacing two Falcon 9 booster engines, effectively reactivating a dormant orbital launch complex, and doing all of the above to a standard capable of satisfying NASA’s strict expectations, SpaceX is officially set to launch the Sentinel 6A oceanography satellite no earlier than (NET) 9:17 am PST (16:17 UTC) Saturday, November 21st. The twist: Falcon 9 will be launching from Vandenberg Air Force Base (VAFB), California for the first time since June 2019.

Meanwhile, back on the East Coast, SpaceX has successfully completed Crew Dragon’s operational astronaut launch debut, clearing the company to focus on its third November mission – Starlink V1 L15. Set to be SpaceX’s 14th dedicated Starlink launch in 2020 alone, Starlink-15 is currently scheduled to lift off NET 10:17 pm EDT (03:17 UTC) on November 21st – coincidentally exactly ten hours of Falcon 9’s Sentinel 6A launch.
https://www.teslarati.com/spacex-two-falcon-9-launches-ten-hours-2020/

Nov. 21: Falcon 9 • Sentinel 6-Michael Freilich
Launch time: 1717 GMT (12:17 p.m. EST; 9:17 a.m. PST)
Launch site: SLC-4E, Vandenberg Air Force Base, California
A SpaceX Falcon 9 rocket will launch the Sentinel 6A, or Jason-CS A, satellite. The satellite is also named Sentinel 6-Michael Freilich in honor of the late director of NASA’s Earth science division. The satellite is a joint mission between the European Space Agency, NASA, NOAA, CNES and Eumetsat to continue the sea level data record previously collected by the Jason series of satellites. Sentinel 6A, built by Airbus Defense and Space and Thales Alenia Space in Europe, will also join the European Commission’s Copernicus Earth observation satellite network. Delayed from Nov. 10 by Merlin 1D engine issue.

Only three of the four landing legs are making contact with the droneship.
The leg closest to the center of JRTI is in the air because the expended crush cores on the opposite legs have made the booster lean such that the leg cannot make contact, even when fully extended.

On a normal, but hard, landing the crush cores are worn down evenly across all four landing legs.
This particular landing must have been uneven for the crush cores to only be used up on one side. This could be because the landing happened during a big wave.

Israeli fighter pilot joins SpaceX’s first private flight for Axiom next year
Quote
CAPE CANAVERAL, Florida — Former Israeli fighter pilot Eytan Stibbe is the second member of the all-private crew that SpaceX is scheduled to launch late next year for Axiom Space, the company confirmed to CNBC on Monday.

President of Israel Reuven Rivlin made the announcement shortly after SpaceX launched its Crew-1 mission for NASA on Sunday evening.
“Eytan Stibbe will fly with the blue and white flag his uniform, reminding us that the sky is no longer the limit!” Rivlin said in a tweet.

Stibbe is set to become Israel’s second astronaut. The nation’s first astronaut was Ilan Ramon, a payload specialist on board Space Shuttle Columbia. He and the other six members of the NASA crew were killed on Feb. 1, 2003 when Columbia broke apart during re-entry.

The Axiom AX-1 mission is scheduled to launch in the second half of 2021, which the company unveiled in a deal with SpaceX earlier this year. Astronaut Michael Lopez-Alegria, who previously worked for NASA and flew to space four times, will be the AX-1 mission commander, with Stibbe set to serve as a mission specialist.

AX-1 would be the first fully private mission to the International Space Station, with Lopez-Alegria and Stibbe flying with two other yet-to-be-named people.

While NASA announced earlier this year that the agency is working with actor Tom Cruise to make a film on board the ISS, Axiom has not confirmed that Cruise is one of the other two passengers for AX-1. …

—- Two SpaceX Launches this weekend (?)
SpaceX still eyeing back-to-back East and West Coast launches this weekend
Quote
Update: Three days later, there’s still a chance that SpaceX will be ready to attempt back-to-back East and West Coast Falcon 9 launches on Saturday, November 21st, potentially launching twice in exactly ten hours if schedules hold.

On the West Coast, a new Falcon 9 rocket has successfully completed a routine static fire test and is likely just hours away from rolling out to SpaceX Vandenberg Air Force Base (VAFB) Space Launch Complex 4E (SLC-4E). The rocket is scheduled to place the international Sentinel 6A oceanographic satellite into a polar orbit, followed by booster B1063’s first landing attempt at Landing Zone 4 (LZ-4).

On the East Coast, Falcon 9 and 60 more Starlink v1.0 satellites went vertical at SpaceX’s Cape Canaveral Air Force Station (CCAFS) Launch Complex 40 (LC-40) pad. It’s unclear if SpaceX will perform a prelaunch static fire test despite the fact that the Starlink-15 mission will be booster B1049’s seventh flight – a first for SpaceX and orbital-class reusable rocketry.

Oddly, SpaceX has yet to update its website with details or confirmation of the two back-to-back launch attempts, raising the possibility of one or both being delayed, but hardware at the pad remains an unequivocal confirmation that at least one of the missions is close to liftoff. As usual, whenever Sentinel 6A and Starlink-15 do launch, SpaceX will host an official webcast on its YouTube channel. …

An up close look at the arms of Octagrabber, the workhorse of the Crew-1 recovery mission. B1061 was nearly taken overboard, presumably by a broadside wave, while Octa was attached. Additional chains were used to further secure the booster until it's safe return. #Crew1

—- Small rocket reusability
Rocket Lab recovers booster after launch in major step toward reusing its small rockets
Quote
“This is the first time we’re actually going to do everything but catch it under a helicopter,” Beck told reporters before the launch.
The recovery happened in the ocean about 400 kilometers off the coast of New Zealand.

“The strongest driver [of the recovery program] is not having to rebuild rockets, so being able to increase production rate is really the key driver,” Beck said. “The ultimate goal here is to get it back in such a condition that we can put it back on the pad, gas it back up, charge the batteries and go. And if we can achieve that milestone then the economics certainly do change quite significantly.”

The benefits and economics of reusing rockets remains a contentious issue in the space industry. SpaceX’s Musk recently blasted competitor United Launch Alliance as “a complete waste of taxpayer money” because its rockets are not reusable. SpaceX has steadily pushed the boundaries of reusing rockets, most notably by landing the booster – which makes up the largest and most expensive part.

Note that Spacex hasn't launched from VAFB in well over a year. After a delay from Nov. 10 by Merlin 1D engine issue, today's launch went off on time. That's a big reliability and mission assurance win for being able to "re-start" the site and go.

Compare:  ULA’s Delta Heavy NROL—44, originally scheduled for June, still hasn’t launched, mostly due to ground service issues.

—- SpaceX’s NASA Falcon Heavy launch debut a step closer as interplanetary payload powers up
By Eric Ralph November 20, 2020
Quote
Maxar Technologies says it’s powered on NASA’s Psyche spacecraft for the first time, pushing the asteroid explorer a step closer to the space agency’s SpaceX Falcon Heavy launch debut.

Despite the many challenges and disruptions posed by the global coronavirus pandemic, Psyche principal investigator Lindy Elkins-Tanton recently noted that the mission to the spacecraft’s namesake metallic asteroid (16 Psyche) remains on track for a narrow 20-day launch window beginning on August 6th, 2022.

Expected to cost approximately $970 million including a relatively relatively affordable $117 million SpaceX Falcon Heavy launch contract, Psyche represents a fairly unique approach to deep space exploration, leaning on commercial off-the-shelf hardware and services as much as possible. To that end, the satellite ‘bus’ – essentially the brain and structural and propulsive backbone of the spacecraft – is moderately tweaked version of Maxar’s SSL 1300 design, proven over some four decades of continuous spaceflight and more than 100 completed satellites. …

—- That Starlink AMA
SpaceX Engineers share details about the Starlink Internet Network
Quote
SpaceX says the dish features technology "more advanced than what's in fighter jets." The technology enables the dish to search for an optimal view of the sky and is capable of reorienting itself. SpaceX engineers shared how the dish is capable of locating the satellites in orbit-- "The Starlink actually has no knowledge of the satellites when it powers on; the constellation is updating all the time so this would be difficult to keep up to date," they said, "The Starlink is able to electronically scan the sky in a matter of milliseconds and lock into the satellite overhead, even though its travelling 17,500 mph overhead. When it detects a satellite the Starlink hones in on its position and makes a request to join the internet. After that, the dish is able to download a schedule of which satellites to talk to next and with that, it can point right at the satellites when the time comes," the engineer(s) wrote via Reddit.

"We’re continuously improving all of the parts of the system. We update all of our satellites weekly, and push software updates to the Starlink dishes, WiFi routers, and phone app every couple weeks.” …
