Astronaut Return Flight Readiness Review Briefing - NASA, SpaceX “Go” for Astronaut Return


Lots of questions in the phone queue, so they moved right along. 49 min.
Recovery explanations.  Reuse:  SpaceX planned reuse all along, for commercial passengers.  NASA gradually came around to that.
Jim B. says the good thing about commercial partners is NASA could grow along with them.
Limiting factors to how long Dragon can stay in free-flight after undocking are food, water, oxygen, Lithium hydroxide CO2 scrubbers.  Water and lithium hydroxide are the biggest factors — they are good for three days, can be stretched longer but they plan for three. “There’s plenty of oxygen.”
The six-hour pre-undocking decisions are due to Dragon cargo loading, including science experiment results that need to be kept in freezers.
Still saying Crew-1 “late September” and Crew-2 “six months later.”

NASA and SpaceX Remain GO for Splashdown
July 30, 2020
Quote
Following a comprehensive review of the latest weather forecast in the areas surrounding each of seven potential splashdown locations, NASA and SpaceX have decided to move forward with plans to bring NASA astronauts Robert Behnken and Douglas Hurley home to Earth with a splashdown off the Florida coast on Sunday, Aug. 2, aboard the SpaceX Crew Dragon “Endeavour” spacecraft.

Teams will continue to closely monitor Tropical Storm Isaias and evaluate impacts to weather around the Florida peninsula, including the potential splashdown sites in the Gulf of Mexico and along the state’s Atlantic coast. NASA and SpaceX will make a decision on a primary splashdown target approximately 6 hours before undocking Saturday.

Undocking remains scheduled for approximately 7:34 p.m. EDT Saturday, Aug. 1, and splashdown at 2:42 p.m. EDT on Sunday. This will mark the first return of a commercially built and operated American spacecraft carrying astronauts from the space station, and it will wrap up NASA’s SpaceX Demo-2 mission after more than two months at the International Space Station.

More details about the return can be found in the Top 10 Things to Know for NASA’s SpaceX Demo-2 Return and the splashdown weather criteria fact sheet.

NASA Announces Astronauts to Fly on SpaceX Crew-2 Mission
Quote
NASA and its international partners have assigned crew members for Crew-2, which will be the second operational SpaceX Crew Dragon flight to the International Space Station as part of NASA’s Commercial Crew Program.

NASA astronauts Shane Kimbrough and Megan McArthur will serve as spacecraft commander and pilot, respectively, for the mission. JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide and ESA (European Space Agency) astronaut Thomas Pesquet will join as mission specialists.
...


Reddit folks add details:

NASA Announces Astronauts to Fly on SpaceX Crew-2 Mission - spacex
https://www.reddit.com/r/spacex/comments/hzezrz/nasa_announces_astronauts_to_fly_on_spacex_crew2/
< Megan McArthur is married to Bob Behnken
< I think its pretty cool Megan McArthur is going to be the pilot on the exact same craft that her husband, Bob Behnken, piloted.
< So the exact same seat position. But probably not the exact same seat, because Crew Dragon has different seat sizes available - IIRC.  So if Bob wants to graffiti a little heart symbol for Megan's attention, he'll have to do it on the instrument panel or something!

< Megan McArthur just made a Twitter account and wished Bob a happy birthday!
https://twitter.com/astro_megan/status/1288097923385790464

<<  The NASA term is a bit weird Doug is the commander and Bob is the pilot but the commander is the one who actually pilots the spacecraft.
< Doug is the Spacecraft Commander.
Bob is the JointOps Commander (i.e. commander of ISS ops from within Demo-2 crew). This position holds the same seat and Dragon-specific responsibilities as the "pilot".
Edit: It's worth noting that, as other comments have pointed out, for most of NASA's history the "Commander" is generally the one who does any manual flying, even when other astronauts have the title "Pilot". I think this is true of Apollo, and I know it's true of the Shuttle, where every landing was flown by the Commander, not the Pilot (though the Pilot was fully qualified to replace the Commander, if need be, and otherwise served as a fully qualified check-pilot supervising the Commander's actions). And that tradition continued with Demo-2, where Doug did most or all of the actual manual control.

[Also:  Shane Kimbrough flew on Shuttle Endeavour.

Universal Pictures committed to funding Tom Cruise's space movie, Deadline reports, with SpaceX partnering on the project that will send Cruise and director Doug Liman to the space station #CruiseDragon

Sources said that Space X’s Elon Musk will be a partner in the project.
How Tom Cruise & Doug Liman Pitched Way To $200 Million Universal Commitment On Space Film With Elon Musk
July 30, 2020 11:31AM PDT
Quote
EXCLUSIVE: What did Universal Pictures execs require to commit to liftoff of the first ever narrative feature film to shoot in outer space? According to sources, all it took was an exuberant Zoom call with Tom Cruise, director Doug Liman, Christopher McQuarrie and PJ van Sandwijk. They pitched the picture with no script (Liman is writing it), and came away with a production commitment around $200 million.

Sources said that Space X’s Elon Musk will be a partner in the project and the expectation is that is that McQuarrie — Cruise’s writer/director on the Mission: Impossible films — will have a ground control role as story advisor and producer alongside Cruise, Liman and van Sandwijk.

The $200 million figure is an estimate, considering the project is still being scripted and the unprecedented logistics, but it costs more to make space-set blockbusters that never require breaking through the atmosphere. It seems a reasonable sum to make movie history for a movie studio in this pandemic moment when streamers are making all the noise.

Deadline revealed in early May that Cruise was working on the space-set action adventure and that he was serious about doing it and that Musk was involved. Deadline broke later that month that Doug Liman would be making the trip with him, and the director who helmed the Cruise pics American Made and Edge of Tomorrow, then went to Florida to witness the launch of the SpaceX Falcon 9 rocket, carrying two American astronauts at the Kennedy Space Center, an historic public-private partnership that put the U.S. back in the business of human spaceflight for the first time in a decade.

Cruise and McQuarrie are back shooting Mission: Impossible Fallout but this is looking more real by the minute. Don’t expect Cruise and Liman to lose their nerve. Both are pilots and their adventurous spirit shows in their filmmaking. As for Cruise, he is a meticulous planner, but fearless in doing his own stunts that have included hanging from a helicopter and the side of a jet plane during takeoff in Mission: Impossible Rogue Nation. In Mission: Impossible: Ghost Protocol he scaled the Burj Khalifa, the Dubai skyscraper, and executed stunts 123 floors up.

No comment all around.

NASA’s SpaceX Demo-2: Teams Targeting Gulf of Mexico for Splashdown
August 1, 2020
Quote
Following a scheduled assessment of weather conditions for splashdown, teams from NASA and SpaceX are proceeding with preparations to bring NASA astronauts Robert Behnken and Douglas Hurley home to Earth aboard the SpaceX Crew Dragon “Endeavour” spacecraft.

Conditions are “Go” at the primary targeted site, off the coast Pensacola, and alternate site off the coast of Panama City in the Gulf of Mexico for splashdown and recovery on Sunday, Aug. 2. Teams will continue to closely monitor Hurricane Isaias and evaluate impacts to the potential splashdown sites.

SpaceX will monitor changes to conditions until 2.5 hours prior to the scheduled undocking, when a determination to proceed with departure will be made. If conditions are marginal and exceed the accepted criteria, a joint recommendation by SpaceX and NASA will be made whether to proceed with undocking at 7:34 p.m. EDT. NASA and SpaceX will make the final decision to proceed after the astronauts are ready inside Crew Dragon just before undocking.

Live coverage of NASA’s SpaceX Demo-2 return will begin at 5:15 p.m. and continue through the targeted splashdown at 2:41 p.m. on Sunday, the first return of a commercially built and operated American spacecraft carrying astronauts from the space station. It will wrap up NASA’s SpaceX Demo-2 test flight after more than two months at the International Space Station. ...

SpaceX Crew Dragon undocks from space station to bring NASA astronauts home for 1st time
Quote
The first astronauts to fly in SpaceX's Crew Dragon spacecraft are on their way back to Earth from the International Space Station.

NASA astronauts Bob Behnken and Doug Hurley, who spent about two months at the space station following the historic launch of the Demo-2 mission on May 30, climbed aboard their Crew Dragon spacecraft today (Aug. 1) and began their 19-hour trip home with a smooth undocking at 7:35 p.m. EDT (2335 GMT). Both craft were sailing nearly 270 miles (430 kilometers) above Johannesburg, South Africa at the time.

"It's been a great two months and we appreciate all you've done as a crew to help us prove out Dragon on its maiden flight," Hurley told the station's crew just after undocking. "We look forward to splashdown tomorrow."

"Safe travels and have a successful landing," station commander Chris Cassidy of NASA replied. He rang the a "ship's bell" on the station as they departed. "Endeavour's a great ship. Godspeed." ...

@Erdayastronaut All correct. Parachutes were originally the backup landing system, with SuperDraco thrusters as primary. Difficulty of proving thruster landing safety *and* architecture being suboptimal for moon/Mars caused us to change focus to parachutes.

GO Navigator is on its way to the splashdown zone off the coast of Florida. Despite being down one generator, the #LaunchAmerica crew's prime recovery ship is well equipped and there is no impact to the timeline.

They may have cut away on purpose, for privacy and respect in a difficult moment, after the astros  had been in weightlessness for two months.  It’s rare to see much of folks exiting the Soyuz until they are all comfortably out of the capsule and arranged nicely for photographs.


Edit:  they are now broadcasting live on the ground in Texas.  Joking about making prank satellite phone calls from the ISS [Edit: from Dragon, see #766 below :) ] just a few hours ago.

https://twitter.com/nasa/status/1290069843174096898 

Another edit:  privacy of the ship’s crew’s identities may have also been a consideration when setting up the video cameras.  The crew was definitely under stress today, dealing with the fuel fumes vs. the requirement to get the hatch open quickly, and some of their... “discussions” looked rather embarrassing.  They did have a photographer at work, so we’ll likely see nice photos later.

Successful autonomous return to earth of the Dragon capsule!  Astronaut egress occurred just over an hour after splashdown, delayed by small concentrations of toxic propellants outside the capsule, discovered after Dragon Endeavor had been brought aboard GO Navigator.  Given the option of exiting earlier, the astronauts radioed that they were fine with waiting, to assure everyone would be safe.

SpaceX Crew Dragon makes historic 1st splashdown to return NASA astronauts home
https://www.space.com/spacex-crew-dragon-demo-2-splashdown.html

The good weather, low wind and glassy sea made for an easy splashdown — but it also allowed a buildup of the toxic combustible gas (common to returning spacecraft), plus an unhealthy concentration of pleasure boaters surrounding the capsule before it had been safed. Coast Guard vessels had maintained a safe area for splashdown, but Pensacola boaters clearly have a lot to learn.

The first question of the press conference addresses all the boats near Dragon.
The Coastguard cleared a 10 nautical mile area prior to splashdown but the boats came in afterward once they saw splashdown. "It's something we need to do better next time."
https://twitter.com/spacexfleet/status/1290030986516783104
< How many @USCG cutters would it require to restrain the boating public's interest and enthusiasm for @NASA @SpaceX ? A lot.
<< I live on the Space Coast. I don’t think that would have happened if the landing was off Cape Canaveral. The people around here know the boundaries when it comes to NASA

Elon Musk and Gwynne Shotwell were front and center at displays in Hawthorne mission control.  After Bob and Doug were safely out, they celebrated the mission success with a little champagne.

I recieved one of these calls at the flight director console. It started with an opening line like "Hi it's Doug and Bob and we're in the ocean." I think my response was "Yeah, I can see that."
~ After the call ended, my witty Capcom Megan Levins suggested that my response SHOULD have been "oh crap, was splashdown supposed to be TODAY?"

The single Raptor engine in SN5 is mounted off-center, because future prototypes will have 3 Raptors in a triangular configuration, per Elon Musk.  That is why the rocket does a “power slide” off the launch mount and the engine does not thrust straight down.  SN5 also rolled (rotated) approximately 90° during its flight, testing the ‘steering’ thrusters.

Trevor Mahlmann (@TrevorMahlmann) 8/4/20, 8:20 PM
There for 20m.
There for 120m.
Here for 150 m.

With certainty, I can say, offset thrust is the best thrust.

SpaceX’s ‘Starhopper’ was the first.

No one would have believed, in the last years of the nineteenth century, that human affairs were being watched from the timeless worlds of space. No one could have dreamed that we were being scrutinised as someone with a microscope studies creatures that swarm and multiply in a drop of water. Few men even considered the possibility of life on other planets. And yet, across the gulf of space, minds immeasurably superior to ours regarded this earth with envious eyes, and they drew their plans against us......

The chances of anything coming from Mars are a million to one, he said

Just so we're clear, SpaceX built a Mars rocket out of rolls of steel, in tents, in South Texas, in weeks. And the first time they flew it, it made a smooth launch, a controlled flight, and safely landed. This is truly remarkable.

SpaceX launches tenth Starlink mission, nails booster’s fifth landing
By Eric Ralph August 6, 2020 
Quote
While Starlink-9 was originally scheduled to launch as early as June 23rd, Principal Integration Engineer John Insprucker – a familiar fixture and voice on SpaceX webcasts – was quick to note that through the more than six subsequent weeks of delays, “Falcon 9 has been trouble-free.” He also partially answered the main question on everyone’s mind, noting that all of those delays could be traced back to bad weather and issues with the mission’s payloads.

Notably, the next two non-Starlink launches currently on SpaceX’s manifest are SAOCOM 1B – the first polar orbit launch from the East Coast in half a century – and Crew-1 – Crew Dragon’s first operational astronaut launch. Scheduled no earlier than late-August and late-September, respectively, both major customer missions are likely to be punctuated by several Starlink launches over the next two months. With Starlink-9 complete, SpaceX could be just 4-5 missions away from rolling out Starlink internet service according to a comment from COO/President Gwynne Shotwell that service could begin after the 14th Starlink launch. ...

—- SpaceX and ULA win military launch competition worth $653 million -- and that's just the start
Quote
New York(CNN Business) Elon Musk's SpaceX and Boeing-Lockheed Martin joint venture United Launch Alliance are the big winners in a stiff competition to secure military launch contracts, teeing up the companies to dominate the lucrative market for launching US national security satellites for years to come.

The initial awards will give $316 million to SpaceX for one launch and $337 million to ULA for two launches. But the total value of the deal could be worth far more, as the military will ask one or the other company to launch additional missions.

SpaceX is expected to handle 40% of all national security satellites slated to go up over the next five to seven years, while ULA will handle the other 60%. Military officials did not say exactly how many launches that might enetail, nor did they provide a total contract value. …

NASA awards DART launch contract to SpaceX
April 11, 2019
Quote
SpaceX will launch a NASA mission to test an asteroid deflection technique at a significantly lower price than past agency contracts won by the company.

NASA said April 11 it awarded SpaceX a contract to launch the Double Asteroid Redirection Test (DART) on a Falcon 9 in June 2021 from Vandenberg Air Force Base in California. The total cost to NASA for the mission, including the launch and related services, is $69 million.

DART is a mission under development at the Johns Hopkins University Applied Physics Laboratory as part of NASA’s planetary defense program. The spacecraft will use an electric propulsion system to travel to the asteroid Didymos. DART will collide with a small moon orbiting Didymos, sometimes nicknamed Didymoon, at a speed of six kilometers per second.

Astronomers will measure the change in the moon’s orbit around Didymos as a result of the impact to measure how well the energy of the impact was transferred to the moon. That will help scientists gauge the effectiveness of the “kinetic impactor” approach proposed as one means of deflecting an asteroid on a collision course with the Earth.

DART originally planned to launch as a rideshare on the commercial launch of a geostationary orbit satellite. The mission switched several months ago to a dedicated launch. NASA did not disclose if DART, which weighs about 500 kilograms, will share the launch vehicle with another spacecraft. …

South Korea mulls exiting its own launch program. South Korean defense industry analysts say the nation would have difficulty competing with other countries in the launch industry, which can provide more advanced technologies and services at lower prices with their already established space-industry infrastructure. "Even if South Korea develops its own rockets, they would not be able to excel more than aerospace giants like SpaceX in terms of technology," said Shin Jong-woo, a senior researcher at the Korea Defense and Security Forum, in The Korea Times.

Ten times the cost ... The country's space institute, KARI, has developed several small-satellite rockets, but these are not competitive with SpaceX's Falcon 9, which recently launched South Korea's first military communications satellite, ANASIS-II. "The costs spent by the South Korean government to develop the two rockets were 10 times higher than those spent by SpaceX," Kim Seung-jo, former president of KARI, said. "But the South Korean government's outcomes in its rocket projects were far behind the Falcon 9 rocket produced by SpaceX."

—- The Military Launch Contract: Another Perspective
SpaceX, ULA win multibillion-dollar military launch contract years in the making
Quote
…  Regardless of the missed opportunities, the NSSL LSA Phase 2 contract is a major win for SpaceX and guarantees the company’s Falcon 9 and Falcon Heavy rockets some 13-14 military launch contracts over a five-year period. For ULA, the victory is like a massive relief, given that the company’s next-generation (expendable) Vulcan Centaur rocket has next to no chance of sustaining itself with commercial launch contracts. Much like Atlas V in the last decade of the rocket’s life and Delta IV over most of its two-decade career, ULA’s Vulcan rocket will continue the trend of relying almost exclusively on US military contracts.

This time around, however, the US military’s preferential treatment of ULA is nakedly obvious. At almost every turn, SpaceX’s Falcon 9 and Falcon Heavy rockets can provide the same launch services as ULA for anywhere from 20-50% less. For the few missions (direct to geostationary) where ULA’s Atlas V, Delta IV, and Vulcan rockets might actually have a step up over SpaceX, the US could have easily awarded ULA the smaller 40% share or even split that 40% share with Blue Origin or Northrop Grumman, giving SpaceX the lion’s share and likely saving hundreds of millions of dollars – if not $1B+ – over the next seven years.

Instead, business (more or less) as usual will continue for at least another decade as the US military functionally subsidizes ULA’s existence by prioritizing a more expensive rocket to achieve the same outcome. The first LSA Phase 2 launches are currently scheduled to begin no earlier than (NET) 2022.

Starlink: SpaceX’s 100th mission may break an incredible reusability record
SpaceX's upcoming launch could raise the bar for reusing rockets.
Quote
SpaceX may be about to take another step in its plan to reuse space rockets.
The company is expected to send up its 11th batch of Starlink satellites in mid-August, sending up 58 craft from Space Launch Complex 40 at the Cape Canaveral Air Force Station in Florida. The mission is also expected to send up three SkySat imagine satellites for Planet as part of a ride-sharing agreement, after the company previously hitched a ride in a Starlink mission in June. The extra satellites will be used to help bring SpaceX's high-speed, low-latency internet connectivity constellation to life.

But SpaceX's mission could be notable for its impressive use of rocket reusability. Eric Berger, senior space reporter at Ars Technica, claimed via Twitter last week that the mission could use a booster that has previously flown five times. This would be the sixth mission for booster B1049, the first time SpaceX has flown the same first-stage rocket that many times.

As Twitter user Simon Merton noted in response, this could be SpaceX's 100th mission. The website SpaceXStats notes that the company has launched 99 missions. Of those, five were with the Falcon 1 rocket, 91 with the Falcon 9 rocket, and three with the Falcon Heavy. SpaceX's first successful launch, and fourth launch overall, was in 2008.

Reusing rockets forms part of its mission to make spaceflight more accessible for all. Landing a booster after flight saves approximately $46.5 million of the $62 million price tag associated with a Falcon 9 launch. That means saving the booster enables SpaceX to reduce the costs of spaceflights even further, which in turn can fund more ambitious projects like a city on Mars. …

SpaceX has big plans to ferry travelers to Mars in the near future, and part of that venture looks to include luxury accommodations while customers spend time with the company on Earth. A recent job board posting for a “Resort Development Manager” has come to light, specifically referring to a project at the launch provider’s Boca Chica Village location in Texas.

“SpaceX is committed to developing this town into a 21st century Spaceport. We are looking for a talented Resort Development Manager to oversee the development of SpaceX’s first resort from inception to completion,” the posting states. …

Back at Cape Canaveral, SpaceX’s Crew Dragon capsule preps for next mission
August 12, 2020 Stephen Clark
Quote
“The capsule is designed for five to 10 missions,” said Gwynne Shotwell, SpaceX’s president and chief operating officer. “We’ll have to see how things work out after we examine the capsule when it gets back to port and back to the Cape to our facilities there, but based on the telemetry and any visible indications that we’ve had so far, the vehicle looks like it’s in really good shape.”

Steve Stich, manager of NASA’s commercial crew program, said SpaceX’s proposal to reuse the Crew Dragon spacecraft “looked like it was a reasonable thing to do.”

“I think part of the question was how long does it take refurbish the vehicle,” Stich said. “It takes about four months or so. We have a lot of margin getting to the flight in the spring timeframe for Crew-2. The vehicle … as gets back to Area 59 at the Cape, it’ll start going through its maintenance.”

Stich said NASA will follow along with SpaceX’s maintenance, “just to make sure that there’s nothing untoward.” …

Starship skeptics
Quote
Eric Berger (@SciGuySpace) 8/11/20, 2:17 PM
After speaking to a few leaders in the traditional aerospace community it seems like a *lot* of skepticism about Starship remains post SN5.  Now, [SpaceX has] got a ways to go. But if your business model is premised on SpaceX failing at building rockets, history is against you.

< Can you go into more detail about their worries? Is it just generic "new designs are always harder than they look" stuff, or is it something specific about the Starship architecture?
Eric Berger:  Everything from "They shouldn't be blowing up that many tanks" to "It's a stunt" to "they're not close to solving the technical problems."

Everyday Astronaut: So wait. [SpaceX is] already the cheapest, one of the most reliable rides to space with an increasing cadence & experience. They could ride the F9 / FH wave for 10+ years with out touching anything & take the market share. Who honestly doubts they won’t make progress w/ Starship
… As in who cares if starship never even does anything but blow up for the next 5 years and then gets canned... F9 / FH are a decade ahead of the competition already! They could scratch further advances entirely and still be a leader.

Nathan Gilmore: In my MBA we studied Kodak, IBM, BlackBerry, few others about failure to recognize but also "acknowledge" threats to their business. I suspect twenty years from now, students will study aerospace industry and how they did not see SpaceX for the threat they truly are.
< No doubt in my mind this will happen. Worst case scenario Starship isn't operational until 2031, most likely it will come into full operation by 2026, at that point it's game over for old space.

< A smarter business model might be making things that can be lifted inexpensively in those rockets.
Susan Witts:  Well, that IS an interesting point. If I can make my satellites out of steel and off-the-shelf modules, with a 3-ton impact shield and a lifetime's-worth of propellant, maybe I can out-craft my competitors with their expensive bespoke every-kilo-counts ultra-engineering?

Tony Tran:
1. Reusability is impossible
2. Reusability is unprofitable
3. Big Fat Steel rocket can't fly
4. Orbital refueling is impossible
5. You can't build a colony on Mars

Neotopiaman:  Most are so behind, it's all they have...
Starship works, then expendable rockets very soon become a rounding error in the share of tonnage to orbit.

Here's some grade-A trolling of Dmitry Rogozin by a priest from Siberia, Father Aleksandr Mikushin.

“May God the Merciful bless you [Elon Musk] and your employees for continued success in the space industry."
ura.news/news/1052444726

Mikushin continues:

"And please send some of your company’s specialists to Russia. May they teach the staffers at the Salyut Construction Bureau how to build re-usable booster stages."

   —-
< Fun fact, so when a colony is built, the colony becomes part of the diocese the ship departed from.
So, the Moon colony will likely fall under the Archdiocese of Orlando.
Which will make it the largest diocese in the Solar System.
<< But if it's a Starship launched from Texas, different diocese.

SpaceX recently submitted a new request with the FCC, seeking to increase the number of Starlink user terminals and Wi-Fi routers to 5 million due to “extraordinary demand.”

SpaceX ‘built a U.S. world-leading manufacturing system' for Starlink
Quote
SpaceX Engineer Matt Monson leads Starlink software development, during a Reddit ‘Ask Me Anything’ session he shared Starlink is “currently generating more than 5TB [5 terabytes] a day of data”. – “Each launch of 60 satellites contains more than 4,000 Linux computers,” Monson wrote. “The constellation has more than 30,000 Linux nodes (and more than 6,000 microcontrollers) in space right now.”

“We’ve had many instances where a satellite on orbit had a failure we’d never even conceived of before, but was able to keep itself safe long enough for us to debug it, figure out a fix or a workaround, and push up a software update,” Monson shared. He also revealed SpaceX is beaming software updates to the Starlink satellites in space approximately once a week, “with a bunch of smaller test deployments happening as well.”

Customers will receive Starlink broadband internet via a user terminal dish and router. SpaceX says it has “invested over $70 million developing and producing thousands of consumer user terminals per month” with a “high-rate production soon to come.” The FCC already approved the operation of 1 million dish terminals in the United States. SpaceX recently submitted a new request with the FCC, seeking to increase the number of Starlink user terminals and Wi-Fi routers to 5 million due to “extraordinary demand.” The company has already initiated a private Starlink Beta testing phase. Employees are actively testing the network before it rolls out service to the public. …

NASA, SpaceX Targeting October for Next Astronaut Launch
August 14, 2020
Quote
Crew-1 will launch in late October to accommodate spacecraft traffic for the upcoming Soyuz crew rotation and best meet the needs of the International Space Station. Launch will follow the arrival of NASA astronaut Kate Rubins and cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov of the Russian space agency Roscosmos aboard their Soyuz MS-17 spacecraft and the departure of NASA astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner from the space station. The launch timeframe also allows for a crew handover with NASA’s SpaceX Crew-2 mission next spring.

The Crew-1 mission is pending completion of data reviews and certification following NASA’s SpaceX Demo-2 test flight, which successfully launched NASA astronauts Robert Behnken and Douglas Hurley to the International Space Station on May 30 and returned them safely home with a splashdown off the Florida coast in the Gulf of Mexico on Aug. 2.  Demo-2 was the first crewed flight test of a commercially-owned and operated human space system.
https://blogs.nasa.gov/commercialcrew/2020/08/14/nasa-spacex-targeting-october-for-next-astronaut-launch/

The next Soyuz crew is currently targeted to launch on Oct. 14.

~ Some Notes:  The blue columns in the center of each fairing show a standardized comparison of payload capacity for each rocket. It shows how much water they can take to LEO, GEO, and TLI. Every single rocket is shown carrying a 3 meter cylinder of water.
~ Next update will get Block 1a and Block 1B SLS, Skylab, and maybe even shuttle.
< Looks like the blue whale would fit comfortably in Starship's fairing. That's very reassuring according to Star Trek
<< Also, I think it’s a humpback. Too short for a Blue.
Other notes:  Starship on-orbit refueling will increase mass to GTO and TLI.  And Lunar Starship will be much lighter than regular Starship, as it will not need the capability to survive earth re-entry.

SN6 begins test campaign as future Starships hatch plans for SpaceX’s next leap
By Chris Bergin  August 16, 2020
Quote
Following the successful test of Starship SN5 during its 150-meter hop just a week ago, the next Starship (SN6) is preparing to repeat the test in the coming days. With a potential tag-team – or hop-team – role for SN5 and SN6, a roadmap is starting to form ahead of the more ambitious tests that will involve Starships SN8 and SN9 – both of which are already under various stages of construction at SpaceX Boca Chica.

With the incredible build and test cadence continuing at SpaceX’s facility in South Texas, a “hot-swap” in the Mid Bay was required after SN5 rolled back from the launch site, following what was the first successful hop of a Starship test vehicle.

With SN6 already assembled in the Mid Bay and waiting patiently for her turn at testing, the two prototypes swapped places, allowing SN5 to take SN6’s slot in the bay, while the latter rolled to the vacated test mount at the launch site. …

Michael Baylor (@nextspaceflight) 8/17/20, 12:56 PM
The reason for the extended SAOCOM 1B delay is due to a range conflict with the NROL-44 mission on nearby SLC-37B, according to the end of this article.
The polar corridor trajectory of the SpaceX launch was likely the source of the issue.

Raptor engine just reached 330 bar chamber pressure without exploding!
https://twitter.com/elonmusk/status/1295495834998513664
[Photo of quiescent engine, and a graph, at the link.]

RCgothic:  330 atmospheres in the combustion chamber. 10% better than June's spectacular 300bar.
The next best is RD-180's 265bar.
Chamber pressure is good for both thrust and efficiency.

< Nice! What SN are you up to now?
Elon Musk:  [Raptor] SN40 is about to be tested & has several upgrades over 330 bar engine. For reference, 330 bar on Raptor produces ~225 tons (half a million pounds) of force.

Everyday Astronaut: Holy crap! You just shattered the record!!! Does hitting that high of target come with some loss in throttling? Because won’t these higher thrust Raptors not throttle?
< What do you mean by throttling? As in controlling how much power you output?
Everyday Astronaut: Exactly! Merlin for example can deep throttle down to under 40% of its max output (I forget the exact number) thanks largely in part to its pintle injector. Raptor hasn’t gone below 50% that I’m aware of and might have a harder time doing so than the Merlin.

Elon Musk:  Max demonstrated Raptor thrust is ~225 tons & min is ~90 tons, so they’re actually quite similar. Both Merlin & Raptor could throttle way lower with added design complexity. Raptor preburner & Merlin gas generator flameout are what limit lower bound.
https://twitter.com/elonmusk/status/1295553672454311941

< Lower thrust would be required for lunar and mars landings no? They’d have to essentially have to hover with much less weight?
Everyday Astronaut:  That’s what those upper engines are for on Lunar Starship. Lower [Thrust to Weight Ratio] and less ground disturbance — real question is what exactly they are (mini Raptors is what we’ve heard!)

Elon Musk:  Very impressive render. Note, legs will be bigger & there’ll be way more stuff in engine bay. Main engines actually do majority of work in turning ship vertical before landing.

Everyday Astronaut:  Another awesome render! I think people might forget how high 20km is! That’s about twice as high as a commercial airliner flies, so watching Starship bellyflop out of the sky at that altitude will be crazy!!!

Elon Musk:  Yeah, Starship will be a tiny dot at 20km. Hard to see with naked eye. We’ll do lots of flights.
