“Boeing’s just not flying yet.”
Axiom finalizing agreements for private astronaut mission to space station
September 23, 2020 Stephen Clark
Quote
“Our customers are private astronauts on these flights, but we don’t fly any private astronauts without a professional astronaut,” Suffredini said. “So the flight will have four seats. We’ll have three customers and an Axiom professional astronaut.”


While astronauts train more than a year to prepare for six-month expeditions on the space station, the private astronauts Axiom plans to fly for a week-and-a-half will undergo about 15 weeks of training, Suffredini said.

Axiom’s customers will spend about half of that time training in Southern California at SpaceX, which provides the Crew Dragon spacecraft, Falcon 9 launch vehicle, spacesuits, and recovery teams to greet the astronauts after their return to Earth. The other half of the training will primarily occur at the Johnson Space Center in Houston to familiarize the passengers with the space station itself, Suffredini said. …

⬇️Photo below.
~ Nosecone & front flaps next week. SN9 next month.
~ First flight is to 15km or ~50,000 ft
~ We just need enough height to test body flaps & drawing propellant from headers vs main tanks. Will do several flights to confirm working well, then add heat shield & go high Mach.

< Sidenote: Did SN7.1 get to an acceptable bar rating before pop? (per SN8 confidence, given the same alloy).
EM:  8 bar differential in ullage, 9 bar at base due to propellant head. It’s enough. Improvements in work.

< It survived?!?! IT SURVIVED!!! And they even fired it at sea level without vacuum conditions (a giant tube)!!! @elonmusk how did it hold up at sea level without flow separation?! It looks like it has a big expansion ratio!
Elon Musk (@elonmusk) 9/25/20, 2:53 AM:  107 expansion ratio. You can a little bit of flow separation towards the end of the nozzle.
< is the solid support ring keeping the engine intact?
Elon Musk:  Yeah, but might not need it
<< It's all about the shape of the bell nozzle. when you are in the vacuum of space the higher your expansion ratio is the more efficient your rocket is. The expansion ratio is the ratio between the exit of the combustion chamber and the end of the nozzle.
< Do you expect the nozzle to collapse inward at sea level, big vacuum between the inside of the nozzle and the exhaust?
<< That is essentially the risk. Merlin Vacuum has a very thin bell extension which would likely be destroyed if it were tested like this. Instead, SpaceX tests them with the extension removed. Raptor's extension is much more complex, precluding that kind of testing. Though more like wobbling until it tore itself apart, rather than imploding.

< Okay newb question but I take it it's not normal for vacuum engines to operate at sea level?
<< No, it's not, the bell is much bigger on a vacuum engine, which usually means the flow at sea level would separate from it before it reached the end, which is very bad
< I think I get it - at vacuum or lower atmosphere pressures the flow expands and fills that chamber better? At sea level the exhaust would narrow and pull away from the bell...? Got some reading and youtubing to do clearly now I'm fascinated
Everyday Astronaut: Check this out! I go through expansion ratios and why it’s not good to fire a vacuum engine at sea level!  youtu.be/D4SaofKCYwo

SpaceX earns NASA contract to launch a probe to research the 'barrier surrounding our solar system'
Quote
Surrounding our solar system lies a barrier of super-hot plasma called the heliosphere, it is a giant wall of fire created by the Sun that defines the edge of interstellar space. NASA plans to send an Interstellar Mapping and Acceleration Probe (IMAP) to research the boundary that separates our solar system from other star systems. Today, September 25, NASA announced it selected SpaceX to launch the agency’s IMAP probe towards the heliosphere atop a Falcon 9 rocket from Launch Complex 40 at the Cape Canaveral Air Force Station in Florida. The mission is scheduled for October 2024.

– “IMAP will help researchers better understand the boundary of the heliosphere, a magnetic barrier surrounding our solar system. This region is where the constant flow of particles from our Sun, called the solar wind, collides with winds from other stars,” the agency explains in a press release, “This collision limits the amount of harmful cosmic radiation entering the heliosphere. IMAP will collect and map neutral particles that make it through, as well as investigate the fundamental processes of how particles are accelerated in space, from its vantage point orbiting the Sun at the Lagrange 1 point directly between the Sun and Earth.” …

So here's what happened to allow #Starlink to still have the Range for tomorrow morning.
#DeltaIVHeavy with #NROL44 slipped again from 28th to "just after midnight" on 29th.
This opened up the earlier parts of the 28th for another launch. #SpaceX had already requested...

 ...and were put back on their originally requested day and time for #Starlink.
Delta IV just after midnight on the 29th also leaves 19 hours left to reconfigure the range back to Falcon 9 for the #GPS3 launch later that same day. So, what we now have is...

CURRENT U.S. LAUNCH SCHEDULE:
28 Sept. @ 10:22 EDT (1422 UTC): #Starlink
29 Sept. @ just after midnight (0400 UTC): #NROL44
29 Sept. @ 21:55 EDT (0155 UTC): [SpaceX] #GPS3

They tried!  Monday’s Starlink launch went to T minus 35 seconds before they scrubbed due to weather (heavy clouds) not clearing at the last moment.  But then ULA’s scrub (also due to weather) probably means SpaceX’s Wednesday GPS3 launch will also be forced to reschedule.

“This is going to sound totally nuts, but I think we want to try to reach orbit in less than six months,” Musk said. “Provided the rate of design improvement and manufacturing improvement continues to be exponential, I think that is accurate to within a few months.”

Only just started building SHeavy so maybe still 6 months to orbit?   ;) :o  ;D

Given Mk1 SN1 SN3 and SN4 failed in tank pressure tests and tank SN7.1 reached acceptable pressure, I do think they are making considerable progress. Such failures would delay others by more than a year and in this year they have hopped SN5 and SN6, made progress with manufacturing capacity and quality, materials .....,

Washington [state] emergency responders first to use SpaceX's Starlink internet in the field: 'It's amazing'
Quote
Washington Emergency Management Division
The Starlink satellite internet network that SpaceX is developing has been used in the field by Washington state emergency responders in recent weeks, the first early application of the company's service to be disclosed.

Washington's state military, which includes its emergency response division, began employing Starlink user terminals in early August to bring internet service to areas devastated by wildfires. User terminals are the small devices on the ground that connect to the satellites. The emergency division has seven Starlink user terminals, which it is deploying with early success.

"I have never set up any tactical satellite equipment that has been as quick to set up, and anywhere near as reliable" as Starlink, Richard Hall, the emergency telecommunications leader of the Washington State Military Department's IT division, told CNBC in an interview Monday.

How Washington's using Starlink
Starlink is the name for SpaceX's ambitious plan to build an interconnected internet satellite network, also known as a "constellation," to deliver high-speed internet to anywhere on the planet.

The full Starlink network is planned to have about 12,000 satellites flying in what is known as low Earth orbit, much closer to the surface than traditional broadband satellites. Hall, whose division has used other satellite broadband services, said "there's really no comparison" between Starlink and traditional networks, where the satellites are farther away from the Earth in Geosynchronous or medium earth orbits.

"Starlink easily doubles the bandwidth" in comparison, Hall said, noting that he's seen more than 150% decreases in latency. "I've seen lower than 30 millisecond latency consistently," he said.

Hall said that, with other traditional services, it typically takes between 30 minutes to an hour to set up a satellite connection, "with a lot less speed and bandwidth and a lot higher latency in a much larger package."

By comparison, Hall emphasized that it took him between five and 10 minutes to set up and connect a Starlink terminal. And a single person can set up one of the devices: "It doesn't require a truck and a trailer and a whole lot of other additional equipment," Hall said.

"I have spent the better part of four or five hours with some satellite equipment trying to get a good [connection]. So, to me, it's amazing," Hall added.

No service fees yet
Musk's company is allowing Washington state to use the Starlink terminals for free, with Hall saying there has been "no fee structure quoted yet."

"The idea is that if we want them long term then we will have come back to table and talk about that," Hall said. "Myself and other folks at my agency want to begin to hash that out because these, at least as far as we're concerned, are here to stay for us. We want to get as many spun out to as many places as we can, so knowing what the cost is going to be is better sooner rather than later."

"SpaceX is being very cautious right now in what they promise us, but it's been nothing but good things," Hall said.

Some notes from Sept 29 NASA Crew-1 press briefings:

Demo-2 Human flight certification wrapping up.  A few items to complete.
Chance of good reentry conditions for capsule and recovery teams was 1 in 7 for Demo-2 (a test spacecraft).  The tougher Crew-1 will be more like 1 in 4.  All equipment including solar panels will be good for 210 days.  Chance of Loss of vehicle calculated at 1 in 276. 

Fixes for Crew-1 capsule: 
- New heat shield tiles in the areas around the trunk attachment bolts that saw a bit more erosion than expected.  New tiles were installed and heat-tested at NASA Ames test center and approved.
- Improved barometric and navigational determination for more precise drogue chute release.
- SpaceX and NASA have worked with the Coast Guard to assure a 10-mile ‘Keep Out’ safe area around the landing zone, clear of extraneous boats, in the future.
- New:  Crew-1 Dragon has software to autonomously move from the forward docking port of Node 2 to the zenith port on that node, to permit other spacecraft to use the forward dock when needed.

Expect four crewmembers in the US side of the ISS going forward; three on the Russian side.  More crew means more science done!  Still working on the agreement with Russia that would put a Russian flyer in each launch from the U.S.  Testing how Dragon’s life-support system handles four people (the maximum NASA plans, along with extra cargo), then will consider flying a full complement of seven for private flights.  During Demo-2, they successfully tested evacuating four people in 90 seconds while docked to the ISS.

All three U.S. Dragon astronauts will vote from space this November.  Victor is looking forward to the “food physiology” experiment he is taking part in, which will entail him eating more fruits and vegetables than the usual astronaut diet.

NASA’s Jim Bridenstine:  There has been “robust enthusiasm” around Demo-2 and the commercial crew program..  Next we need to work toward space habitation outside of the ISS.  The ISS won’t last forever, and we don’t want a gap in LEO habituation.

The ISS has been tracking a slow atmospheric leak, which has increased a bit recently.  They believe they have narrowed it down to the Russian service module.  Scheduled ‘consumables’ resupply should be sufficient until at least next spring, so the investigation and discussions continue, as do planned launches.

SpaceX will do a static fire of the new booster, then a final launch day full dress rehearsal with astronauts and the SpaceX team.  The Crew-1 booster will also launch Crew-2.

In order to dock Crew-1 to the ISS at the desired time, a 25-hour flight time is required and the early-morning launch.  (2:40am ET Saturday, Oct. 31)  That launch time also fits in best with ISS sleep periods.  Besides, “Night launches are beautiful.” 

SpaceX’s Hans Koenigsmann:  After Crew-1, with the next Cargo Dragon, this will be the first time two Dragons are docked to the Station. Going forward from 2021, we should always have at least one Dragon on the ISS at all times. “It is our great pleasure and we are humbled to be the nation’s premiere provider to the ISS.”

Breaking news:  Crew-1 has named their spacecraft (Crew Dragon #207):  Resilience.
The astronauts purposely did not include their names on the mission patch, because, rather than just their own mission, they wanted it to symbolize more:  the beginning of a new era in spaceflight.  The symbols at the bottom of the patch are for previous U.S. space capsules:  Mercury, Gemini, and Apollo.

The launch of the ULA #DeltaIVHeavy #NROL44 mission has been scrubbed. The local weather resulted in a significant delay to pre-launch preparations including the roll of the Mobile Service Tower (MST).

When the MST roll began we discovered a hydraulic leak in the ground system required to move the tower which needs further evaluation. Subsequent weather will prevent the team from moving forward with tonight’s attempt. Launch is now scheduled for 11:54 pm EDT on Wed., Sept. 30.

NASA Looks to Advance 3D Printing Construction Systems for the Moon and Mars
Quote
The process of building landing pads, habitats, and roads on the Moon will likely look different than the common construction site on Earth. Excavation robots, for one, will need to be lightweight yet capable of digging in reduced gravity. A large-scale construction system could be autonomous and equipped to work without astronauts' help.

As part of the Artemis program, NASA has a concept for the core surface elements needed to establish a sustained presence on the Moon, which emphasizes mobility to allow astronauts to explore more and conduct more science. NASA is considering putting in place a lunar terrain vehicle, habitable mobility platform or lunar RV, and surface habitat on the Moon by the end of the decade. The agency is investing in advanced manufacturing – one of five industries of the future to enable space exploration and improve life on Earth – including technologies that could find and use available resources on the Moon and Mars to build out future infrastructure.

Today, NASA is working with ICON, a construction technologies company based in Austin, Texas, on early research and development of a space-based construction system that could support future exploration of the Moon and Mars. The company has 3D printed communities of homes and structures on Earth and participated in NASA’s 3D Printed Habitat Challenge, demonstrating a construction method and technologies that may be adaptable for applications beyond our home planet.

A Japanese astronaut is in talks to join SpaceX's artist-filled Starship mission around the moon
Oct 1, 2020
Japanese astronaut Soichi Noguchi is slated to fly on the first operational SpaceX Crew Dragon mission, called Crew-1, but is also hoping to join a lunar flight.
Quote
   •   SpaceX plans to launch a mission around the moon in 2023 with its reusable steel Starship vehicle.
   •   Japanese billionaire Yusaku Maezawa is funding the private voyage, called #dearMoon, and plans to bring along a handful of artists plus an astronaut or two.
   •   Soichi Noguchi, a JAXA astronaut who's slated to fly on SpaceX's upcoming Crew-1 mission, say he's talking to Maezawa about possibly joining the circumlunar flight.
   •   "Who knows? I may have a chance to fly," Noguchi told Business Insider

In fact, Maezawa bought all of the available seats on the lunar demonstration flight of Starship — a roughly 16-story steel spacecraft — and is hand-picking the entire crew of his mission, called #dearMoon.

Maezawa, an avid art collector and rock musician, says he hopes to launch "an awe-inspiring, global, universal art project" by flying up to eight artists at no cost to them. Those selected, he said, may include musicians, sculptors, painters, film directors, dancers, photographers, architects, novelists, and fashion designers.

"What I want to do is show the people of Earth just how beautiful our planet is by taking artists up there," Maezawa told CNN in 2018, according to a translation, "so that they can convey the beauty to the world in their words."

So far, Maezawa has spoken publicly about the mission with former Beatle Ringo Starr, "First Man" director Damien Chazelle, and actor Ryan Gosling (who declined). Musk also said he'd consider flying on the mission.

But the SpaceX CEO apparently told Maezawa to bring along seasoned spaceflight professionals since the mission will be dangerous. "After a press conference, we talked a lot at Elon's home. He said that it would be reliable if 1-2 astronauts will be on board," Maezawa tweeted in 2018. …

After two scrubs, Elon Musk says he will visit SpaceX launch sites in Florida
Quote
So what is going on? SpaceX has now launched its Falcon 9 rocket more than 90 times, and before this week, recent delays have almost exclusively been due to weather rather than technical problems with the rocket or its ground systems.

Musk apparently wants to know as well. After the back-to-back scrubs, he took to Twitter to announce that he would visit the company's two launch sites in Florida: one at Cape Canaveral Air Force Station (the site of Friday night's scrub) and one at Kennedy Space Center (where the Starlink mission awaits a second launch attempt).

Visiting next week
Musk would like SpaceX to increase its cadence such that it can reach 48 launches in 2021, which would more than double the company's previous record for total number of missions in a single year. Technical scrubs like the ones this week would prevent this. Achieving frequent launches will require smooth operations.

"We're doing a broad review of launch site, propulsion, structures, avionics, range & regulatory constraints this weekend," Musk tweeted. "I will also be at the Cape next week to review hardware in person."

This visit is notable, because Musk is now spending most of his time in Boca Chica, Texas, working on the company's next-generation launch system, Starship. Now, he will be returning his focus to the Falcon 9 for a time.

This will matter, because Musk truly serves as both the chief executive of SpaceX as well as its chief engineer. He leads the discussion at all senior technical meetings, whether in his executive conference room at the SpaceX factory in Hawthorne, California, or a larger room in Boca Chica. ...
https://arstechnica.com/science/2020/10/after-two-scrubs-elon-musk-says-he-will-visit-spacex-launch-sites-in-florida/

A similar critical review after early Starship failures led to a huge ramp in hiring at Boca Chica, more individual responsibility, and multiple shifts for 24/7 construction progress.

The first Super Heavy prototype has entered assembly operations, with the forward barrel sleeved. A Super Heavy fuel stack section was also spotted.   ➡️youtu.be/IWUC7EyXJt8

< is there any substantial difference between ring sections of Starship and Super Heavy? Safe to assume Super Heavy uses thicker steel rings to support higher loads, right?
Elon Musk: The ship rings are thicker than they need to be (for now), so same thickness works for booster & ship for hoop stress. Booster lower tank will have longitudinal stiffeners to prevent buckling.

< I remember u saying that the initial few iterations Superheavy will have 28 engines instead of 31, so regarding this engine upgrade, is it to accommodate/allow a heavier tank with more propellant?
< Correct me if wrong, this upgrade will allow each tanker flight to deliver ~300 tonnes of propellant to LEO while reserving ~30 tonnes of landing propellant ...
< And ultimately this upgrade will result into cutting the number of refuelling flights to 4 instead of 8 which would be a huge improvement!
Elon Musk:  Probably 5 or 6 with an optimized tanker, although filling up the ship in orbit isn’t required for Mars, so 4 is possible.

Breaking news: SpaceX and L3Harris win Space Development Agency contracts to build missile-warning satellites. SpaceX is developing a new satellite for DoD based on the Starlink design.

SpaceX, L3Harris win Space Development Agency contracts to build missile-warning satellites
October 5, 2020
Quote
WASHINGTON — The Space Development Agency awarded SpaceX a $149 million contract and L3Harris a $193.5 million contract to each build four satellites to detect and track ballistic and hypersonic missiles.

The contracts announced Oct. 5 are for the first eight satellites of a potentially much larger Space Development Agency constellation of sensor satellites known as Tracking Layer Tranche 0. This is SpaceX’s first military contract to produce satellites.

Both companies have to each deliver four satellites by September 2022, Space Development Agency Director Derek Tournear told SpaceNews.

“We want to show that we can take commoditized commercial components and perform a DoD mission,” said Tournear.

All eight satellites will be launched in 2022 for a demonstration of the Tracking Layer. The next step will be to add 28 more wide field-of-view satellites and one or two “medium field of view” satellites that will be developed by the Missile Defense Agency. The medium field-of-view sensors provide more specific target location data to cue weapons automatically. …

UK-based robotic rover startup Spacebit has booked a second payload delivery to the Moon, aboard the Nova-C lander that Intuitive Machines is planning to send in 2021 as part of NASA’s Commercial Lunar Payload Services (CLPS) program. Spacebit already has a berth aboard the Astrobotic Peregrine lander that’s set to go to the Moon in July 2021, flying atop a Vulcan Centaur rocket, and so this would follow quickly on the heels of that mission, with a current mission timeframe of October 2021 to deliver the Intuitive Machines lander via a SpaceX Falcon 9. …

Russia has clearly decided that if you can't beat 'em, join 'em with its new design for a reusable booster. Alas, no flights until at least 2026 means it will be at least 15 years behind the Falcon 9. Russia is lucky SpaceX doesn't innovate, hah https://twitter.com/sciguyspace/status/1313165995452903425

Elon Musk (@elonmusk) 10/5/20, 9:07 PM

 It’s a step in the right direction, but they should really aim for full reusability by 2026. Larger rocket would also make sense for literal economies of scale. Goal should be to minimize cost per useful ton to orbit or it will at best serve a niche market.
https://twitter.com/elonmusk/status/1313284721426796546 

A Falcon 9 clone! ;D  Except they are using only five engines on the first stage — burning methane and oxygen like Starship Raptors.  They plan 10 flights of each booster with minimal refurbishment, and 100 flights total….

Excerpt via google translate:
Quote
The first stage of the "Amur" will return to the landing sites…
According to Pshenichnikov, the creation of an offshore landing platform for the Amur is not yet considered, since the weather conditions in the Sea of ​​Okhotsk greatly complicate the stable operation of such a floating platform.  “However, we do not exclude landing at sea with the subsequent pick-up of the stage, including by special ships, and will be considered within the framework of the draft design,” the specialist added.

Aerospace Safety Advisory Panel urges NASA to build cross-program computer test capability for Artemis
By Philip Sloss October 7, 2020
Quote
The Aerospace Safety Advisory Panel (ASAP) expressed its concern about the integrated computer testing capabilities across the three separate programs under the Exploration Systems Development (ESD) division of NASA’s Human Exploration and Operations Mission Directorate. The Exploration Ground Systems (EGS), Orion, and Space Launch System (SLS) programs under ESD are working together to accomplish upcoming Artemis lunar missions, but have been independently funded and managed throughout their post-Constellation program formulations.

During the ASAP’s fourth quarterly meeting of 2020, the panel highlighted the absence of the ability to test a complete set of the flight computer avionics and software that will fly on upcoming Artemis launches, which includes not just those ESD program components, but also United Launch Alliance’s (ULA) Common Avionics computer system. In the aftermath of the computer software in-flight anomalies on Boeing’s Orbital Flight Test-1 (OFT-1) mission last December, the panel agreed with points made in an internal NASA Engineering and Safety Center (NESC) report and recommended establishing the resources for end-to-end, integrated testing of all the flight computer systems. ...

SpaceX's Starman and Elon Musk's Tesla Just Made Their 1st Mars Flyby
https://www.space.com/amp/spacex-starman-tesla-mars-flyby



Starman just cruised by Mars for the first time.

The spacesuit-clad mannequin is "driving" SpaceX founder and CEO Elon Musk's Tesla Roadster, which launched in February 2018 on the debut flight of the company's powerful Falcon Heavy rocket. And the duo just hit a big milestone on their cosmic journey.

"Starman, last seen leaving Earth, made its first close approach with Mars today — within 0.05 astronomical units, or under 5 million miles, of the Red Planet," SpaceX announced via Twitter Wednesday (Oct. 7). (One astronomical unit is the average Earth-sun distance — about 93 million miles, or 150 million kilometers.)

https://twitter.com/SpaceX/status/1313974379999494144

... There's a starman waiting in the sky
He'd like to come and meet us
But he thinks he'd blow our minds
There's a starman waiting in the sky
He's told us not to blow it
Cause he knows it's all worthwhile
He told me:

Let the children lose it
Let the children use it
Let all the children boogie

I had to phone someone so I picked on you
Hey, that's far out so you heard him too
Switch on the TV we may pick him up on channel two
Look out your window I can see his light
If we can sparkle he may land tonight
Don't tell your poppa or he'll get us locked up in fright

There's a starman waiting in the sky
He'd like to come and meet us
But he thinks he'd blow our minds
There's a starman waiting in the sky
He's told us not to blow it
Cause he knows it's all worthwhile
He told me:

Let the children lose it
Let the children use it
Let all the children boogie ...

Starship Troopers?  DoD USTRANSCOM-SpaceX Accord Raises Policy Eyebrows
https://breakingdefense.com/2020/10/starship-troopers-transcom-spacex-accord-raises-policy-eyebrows/



WASHINGTON: US Department of Defense Transportation Command’s (USTRANSCOM) inked a new partnership with SpaceX and XArc to study whether cargo, and troops, could be rapidly transported to hot spots via spacecraft. It’s got both air power and space analysts shaking their heads — both in admiration and skepticism.

While generally lauding USTRANSCOM for its willingness to consider new ideas — and raising a toast to the continued marketing genius of SpaceX founder Elon Musk — a number of experts (including some wearing uniforms) caution that the viability of using commercial spacecraft to ferry logistics across the globe remains in doubt for technical, economic and even bureaucratic reasons.

Many can remember the ridicule the Marine Corps endured starting back in 2002 when leaders put forth the Small Unit Space Transport and Insertion, or SUSTAIN, concept to ferry Marines around the globe on a suborbital transport.

https://apps.dtic.mil/dtic/tr/fulltext/u2/a513739.pdf

Army Gen. Stephen Lyons, head of TRANSCOM, announced the deal, made under a Cooperative Research and Development Agreement (CRADA), yesterday at the National Defense Transportation Association. “There is a lot of potential here and I’m really excited about the team that’s working with SpaceX on an opportunity, even perhaps, as early as ’21, to be conducting a proof of principle,” he said.

“We are currently referring to moving the equivalent of a C-17 payload anywhere on the globe in less than an hour. As technology changes, we may be able to move more cargo through space,” a TRANSCOM spokesperson explained in an email yesterday

“Through the CRADA we are looking at investigating the technical possibility of using SpaceX’s Starship Super Heavy launch vehicle to deliver cargo and troops, and this could be launch and land on ground, launch and land at sea, or a combination of the two,” the spokesperson added.

.... TRANSCOM said the CRADA with SpaceX will also investigate the legal, diplomatic, statutory, and regulatory issues that must be addressed to enable the normalization of high-frequency, point-to-point, commercial space launches.”

For example, said Secure World Foundation’s Victoria Samson, the advent of military transport through space would raise a host of regulatory issues.

“These activities may be physically possible, but how will other states determine that it isn’t an incoming warhead?”

“Where would these craft be taking off/landing? Will we have spaceport bases in allied territory, and if not, how does this benefit our troops overseas if we still have to move them through ground transportation systems?”



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

The United States Transportation Command (USTRANSCOM) is one of eleven unified combatant commands of the United States Department of Defense.

(USTRANSCOM) mission is to "provide global air, sea and land transportation to meet national security needs during peace and war".

Space is becoming too crowded, Peter Beck of Rocket Lab warns. CEO Beck said that the sheer number of objects in space right now—a number that is growing quickly thanks in part to SpaceX's satellite Internet constellation, Starlink—is making it more difficult to find a clear path for rockets to launch new satellites. "This has a massive impact on the launch side," ... Rockets "have to try and weave their way up in between these constellations."

NRO to launch secret mission on Falcon 9. The National Reconnaissance Office has confirmed it will launch a payload on a SpaceX Falcon 9 rocket from Cape Canaveral later this month, Spaceflight Now reports. This mission was not publicly disclosed until recently. An NRO spokesperson confirmed Monday that NRO is the customer for the Falcon 9 launch scheduled no earlier than October 25.

The US military and Elon Musk are planning a 7,500-mph rocket that can deliver weapons anywhere in the world in an hour
Quote
   •   The US military is teaming up with Elon Musk's SpaceX to build a rocket capable of delivering weapons around the world at 7,500 mph.
   •   The plans call for a rocket that can carry 80 metric tons of cargo into space and land anywhere in the world in about an hour.
   •   SpaceX will now assess the costs and technical challenges of the project, while initial tests are expected in 2021.

Elon Musk's SpaceX and the US military plan to build a rocket capable of delivering 80 metric tons of cargo anywhere in the world in 60 minutes.

Under a newly agreed contract, SpaceX will assess the costs and technical challenges of the project, while initial tests are expected in 2021, Gen. Stephen Lyons, the head of US Transportation Command, said Wednesday at a virtual conference.

A 7,652-mile journey from Florida to Afghanistan could be completed within about an hour with such a high-speed rocket, which could travel at 7,500 mph, per The Times.

In comparison, a US C-17 Globemaster, a military transport aircraft costing $218 million with a maximum speed of 590 mph, would complete this journey in about 15 hours.

"Think about moving the equivalent of a C-17 payload anywhere on the globe in less than an hour," Lyons said.
"I can tell you SpaceX is moving very, very rapidly in this area. I'm really excited about the team that's working with SpaceX."

Another aerospace company, Exploration Architecture Corporation, will also be part of the research program. …

SpaceX crew launch delayed to assess Merlin engine concern
Quote

The engine concern appeared during an Oct. 2 launch attempt of a Falcon 9 rocket with a GPS satellite at Cape Canaveral, prompting computers controlling the final seconds of the countdown to abort the mission just two seconds prior to liftoff.

Elon Musk, SpaceX’s founder and CEO, tweeted after the abort that the countdown was stopped after an “unexpected pressure rise in the turbomachinery gas generator,” referring to equipment used on the rocket’s Merlin main engines. The gas generators on the Merlin 1D engines drives the engines’ turbopumps.

While the Falcon 9 launch of the U.S. Space Force’s next GPS navigation satellite remains grounded, SpaceX proceeded with the launch of a different Falcon 9 rocket Oct. 6 from a neighboring pad at NASA’s Kennedy Space Center. That mission successfully placed 60 more Starlink internet satellites into orbit.

In a statement Saturday, NASA said the Crew Dragon launch delay from Oct. 31 will allow SpaceX more time “to complete hardware testing and data reviews as the company evaluates off-nominal behavior of Falcon 9 first stage engine gas generators observed during a recent non-NASA mission launch attempt.”

The Crew Dragon mission will use the same type of Falcon 9 rocket as the GPS and Starlink launches.
NASA said it has “full insight” into SpaceX’s launch and testing data. SpaceX developed the Crew Dragon spacecraft and flies the capsule under the auspices of a multibillion-dollar contract with NASA. …

Germany's Exolaunch signs long-term launch contract with SpaceX
Quote
Exolaunch, a German company that provides management services to deploy small satellites, announced on October 7th it signed a long-term launch contract with SpaceX to launch satellites atop Falcon 9 rocket missions throughout 2020 and 2021. The contract falls under SpaceX's SmallSat Rideshare Program, which allows companies to launch satellites to space destinations for a lower cost by sharing Falcon 9's fairing with a larger payload during a mission.

“SpaceX program is a game-changer for the rideshare launch industry giving new impetus for numerous constellations of small satellites. Teaming up with SpaceX, we are able to offer our customers seamless, reliable, and cost-effective launch solutions and expand access to space,” the Vice President of Launch Services at Exolaunch Jeanne Medvedeva stated in a press release on Wednesday.

The first mission is scheduled for December this year. A Falcon 9 rocket will deploy 30 small satellites to sun-synchronous orbit. “Our first mission with Falcon 9 later this year will set the precedent for our rideshares going forward, and we are delighted to extend partnership with SpaceX,” Medvedeva said. Some of Exolaunch’s customers that will ride atop SpaceX's rocket include: German Aerospace Center, Loft Orbital, Swarm Technologies, NanoAvionics, German universities, among a variety of commercial customers.

60's Cold War Rocketship Ithacus Would Have Hauled a Battalion of Jet-Troops Anywhere — In an Hour
https://medium.com/war-is-boring/this-cold-war-concept-envisioned-space-marines-with-jetpacks-5a3ee398d42e


1963 - Douglas ICARUS (InterContinental Aerospacecraft Range-Unlimited System - “Intercontinental Aerospace System of Unlimited Radius of Action”)/ a.k.a. Ithacus

In the early Space Age, everything seemed possible — no matter how crazy.

Which is why, in the 1960s, one American engineer seriously designed a space rocket to transport 1200 troops wearing jetpacks. This far-out concept aimed to lob Marine jet-battalions into space and land them on the other side of the world in less than an hour.

Marine general Wallace Greene, Jr., publicly proposed a ballistic transport system when Pres. John F. Kennedy nominated him to lead the Marine Corps in October 1963.

The impact of this application of space technology on the projection of national military power is staggering to contemplate,” Greene said.

... Had it ever left the drawing board, Ithacus’ half-million pound payload could have sent 130 tons of cargo just as far — and just as fast — as Icarus would have.

The Pentagon could have deployed its rocket transports by the early 1980s.



... The main element of the rocket was supposed to be a body with a diameter of about 80 feet (a little less than 25 m) and a height of 210 feet (64 m).

During cargo flights, the crew would have ridden in a Star Wars-style escape pod, bailing out in case of disaster. But the troop transport version lacked the escape pod, presumably for morale reasons.

Troops would strap themselves into acceleration couches on six decks — their gear stored within reach. Upon landing, the Marines would have exited the rocket via jetpacks and giant slides. Winches and cranes would lower cargo from the troop decks to the ground.

Once securing the landing zone, the Marines would next refuel Ithacus enough for it to hover on its aerospike and fly itself to a coastline. There, a giant barge and derrick would carry it back to the United States for reuse.

Reddit comment, Re doubts about Elon’s “few weeks” and “October presentation” timelines:
< Amusingly though, we're somehow almost on the 2016 ITS timeline still (which had first orbital flight in 2020, now likely to slip into 2021 but still before SLS flies)   I think the switch to steel was a history-making good idea. It's hard to estimate how much it shortened development times, but the easy answer looks to be "years".

Tiles will be on hot side of flaps too. A very tough problem is sealing the moving flap to body joint without melting or shredding the seal.

Viv: Are you still considering transpiration cooling for most vulnerable hotspots or are the heat shield tiles tough enough?
Elon Musk:  It might be used in some areas. ITAR laws prevent us from being too specific about solutions.
Everyday Astronaut:  Makes sense considering transpirational cooling was originally used to help warheads survive reentry! :o

< Does ITAR even do anything? Feels pretty ancient
Everyday Astronaut: It’s still quite strict with huge penalties... but I find it odd Elon can post full blown pictures of the Raptor in all of its glory. Perhaps at that point it’s like “if you can reverse engineer this engine from these pics, you deserve it” ;D

More on Starship Earth-to-Earth (E2E).
[And you thought my vision of Starship delivering large payloads anywhere in the world after disasters was just a fever dream.]

The US military and Elon Musk are planning a 7,500-mph rocket that can deliver weapons anywhere in the world in an hour
Quote
   •   The US military is teaming up with Elon Musk's SpaceX to build a rocket capable of delivering weapons around the world at 7,500 mph.
   •   The plans call for a rocket that can carry 80 metric tons of cargo into space and land anywhere in the world in about an hour.
   •   SpaceX will now assess the costs and technical challenges of the project, while initial tests are expected in 2021.

Elon Musk's SpaceX and the US military plan to build a rocket capable of delivering 80 metric tons of cargo anywhere in the world in 60 minutes.

Under a newly agreed contract, SpaceX will assess the costs and technical challenges of the project, while initial tests are expected in 2021, Gen. Stephen Lyons, the head of US Transportation Command, said Wednesday at a virtual conference.

A 7,652-mile journey from Florida to Afghanistan could be completed within about an hour with such a high-speed rocket, which could travel at 7,500 mph, per The Times.

In comparison, a US C-17 Globemaster, a military transport aircraft costing $218 million with a maximum speed of 590 mph, would complete this journey in about 15 hours.

"Think about moving the equivalent of a C-17 payload anywhere on the globe in less than an hour," Lyons said.
"I can tell you SpaceX is moving very, very rapidly in this area. I'm really excited about the team that's working with SpaceX."

Another aerospace company, Exploration Architecture Corporation, will also be part of the research program. …

At the beginning of the COVID-19 pandemic, the US Federal Emergency Management Agency (FEMA) launched “Project Airbridge,” partnering with commercial air cargo companies to bring millions of medical supplies into the country. The effort accelerated supply transport from the conventional 30-40 days shipping time frame to a two-day process via airplanes, and a total of around 250 flights were completed before the project was phased out in June. The recent US Military-SpaceX study would likely include case study solutions for scenarios like Project Airbridge, possibly reducing both the time and flights required to transport the tons of supplies that were needed. …

—- Musk ... SpaceX Moon and Mars update 

“For there to be a self sustaining city on Mars we will need a million people at the intersection of the set people who want to go to mars and the set of people who can afford to go. When the will and the way intersect then we will be a multi-planetary species” — @elonmusk
https://twitter.com/reallifestarman/status/1317534207845953536
At the link: Elon clip from the Mars Society webcast. 
Sustainable establishment means more than “a few people or a base.” Need a city so if the ships from earth stop coming, for any reason, the Mars colony can survive.

Here is the full discussion (starts about 30 minutes in):
2020 Mars Society Virtual Convention
➡️https://www.youtube.com/watch?v=y5Aw6WG4Dww

It’s not a “presentation;” there are no slides or prepared talk, just a Q&A.
Some highlights:
Quote
Michael Baylor (@nextspaceflight) 10/16/20, 6:23 PM
Here we go...
Initial booster flights with 2-4 engines rather than 28. Really need to avoid losing 28 engines in a failure scenario.
Will also likely take a few tries to get the atmospheric reentry on Starship down.
https://twitter.com/nextspaceflight/status/1317229795097202688
< Elon Musk: 80-90% confident Starship will reach orbit next year.
Michael Baylor: Elon is now joking about Boeing and Lockheed not building expendable planes but building expendable rockets.
[If SpaceX was just trying to beat them, that would not be nearly enough innovation to get to Mars.  Need much more, exponential progress]
< Ships, planes, Horses & rockets:  everything that isn't re-usable is stupid LOL. 

My notes:
Orbital cryo-refueling maybe in 2022. (Another reason for using methane:  its cryotemps are close to that of oxygen, so tanks can be integrated next to each other.  RP-1 would freeze.  [Liquid hydrogen would freeze the oxygen.]) Oxygen is dense, and cheap to make — basically “just the cost of electricity.”
Moon ship prototype in 2-3 years. 100 ton capability as soon as orbital refueling is established.

Robert Zubrin: with Starship, SpaceX is redeveloping the Saturn V, the Space Shuttle, plus orbital refueling (which has never been done).  And not just developing a ship, but a shipyard, for a massive fleet of ships.

< Looks like it went through the net, hit one of the struts that hold up the net, and then slid down towards the deck.

SpaceX has confirmed that the crew is safe.
The corner of the net of this ship (Ms. Tree) gave way and caused the fairing to drop down.

~ To date, Ms. Tree has caught seven fairing halves and Ms. Chief has caught two.
Ms. Chief has a lot of catching [;D] up to do

Found a visual taken at Port of LA showing just how thick the ships arm struts are. May 2018

—-  ULA DELTA IV HEAVY NROL-44: the adventure continues

The issue that caused the automated abort is understood and resolved. A sensor incorrectly reported that a valve in the RS68A was not in the flight position. We have implemented a change that will better verify its position. Currently working thru an issue with pad hydraulics
< What part of the hydraulic system broke this time? And is it a easy fix?
Tory Bruno:  Swing arm. Fixing is always easy. Making sure something stays fixed takes more work and lots of discipline.

ULA (@ulalaunch) 10/16/20, 9:25 AM
The #NROL44 launch date is now indefinite on the range. With continued emphasis on mission success, our team will continue to test and evaluate the swing arm retraction system prior to the launch of the #DeltaIVHeavy. We will confirm a launch date as soon as possible.

< Here before the elon fanboys absolutely flood this reply section. Good luck ULA!
<< Calm down, man. Rockets are very complex, and nobody wants ULA to fail.
It's just that there is a certain irony in Tory Bruno talking up the reliability and operational record of the company while their $350M premium rocket has repeated technical delays.
> To be fair, it sounds like a ground problem, rather than an issue with the rocket itself.
>> True enough, but as a rebuttal, this sort of thing will happen when you only use the pad every year or two. With only 4 D4H flights left, there's no return to investing millions to refurbish it, so we are likely to keep seeing these issues.
