Has Axiom been been studying the Starship Users Guide*?  Because that new module looks suspiciously like the size of Starship’s payload fairing. :)

Axiom Station's fifth design analysis cycle is complete, introducing a significant change to the world's first commercial space station.
The former Node and Hab have been combined into the Axiom Hub module, the central nexus of future human activity in Earth’s orbit.


~ With two Hubs, the Axiom Station crew capacity and number of radial ports both stand at eight … for now.

~ The Axiom Lab module is the next step for astronaut-tended manufacturing & research in space. What industries could you reshape in microgravity?

~ The Axiom Power Tower’s solar array, expanded ECLSS, and EVA airlock complete the first iteration of the Axiom Station and ready it to fly solo.

~ The pillar of a thriving ecosystem of commercial activity, manufacturing innovation, and breakthrough research in space.
The platform empowering exploration of the Solar System.

Component Failure In NASA’s Deep-Space Crew Capsule Could Take Months to Fix
https://www.theverge.com/platform/amp/2020/11/30/21726753/nasa-orion-crew-capsule-power-unit-failure-artemis-i

Engineers are racing to fix a failed piece of equipment on NASA’s future deep-space crew capsule Orion ahead of its first flight to space. It may require months of work to replace and fix. Right now, engineers at NASA and Orion’s primary contractor, Lockheed Martin, are trying to figure out the best way to fix the component and how much time the repairs are going to take.

In early November, engineers at Lockheed Martin working on Orion noticed that a power component inside the vehicle had failed, according to an internal email and an internal PowerPoint presentation seen by The Verge. Known as a power and data unit, or PDU, the component is a “main power/data boxes,” according to the email, responsible for activating key systems that Orion needs during flight.

NASA had planned to transfer the Orion capsule to the Multi-Payload Processing Facility (MPPF) at KSC on December 7th, though that rollout may be postponed due to this issue. When asked for a comment, NASA directed The Verge to a short blog post published today outlining the failure. Lockheed Martin did not respond to a request for comment ahead of publication.

https://blogs.nasa.gov/artemis/2020/11/30/update-on-orion-final-assembly-and-transfer/

Replacing the PDU isn’t easy. The component is difficult to reach: it’s located inside an adapter that connects Orion to its service module — a cylindrical trunk that provides support, propulsion, and power for the capsule during its trip through space.

To get to the PDU, Lockheed Martin could remove the Orion crew capsule from its service module, but it’s a lengthy process that could take up to a year.

As many as nine months would be needed to take the vehicle apart and put it back together again, in addition to three months for subsequent testing, according to the presentation.


Lockheed has another option, but it’s never been done before and may carry extra risks, Lockheed Martin engineers acknowledge in their presentation. To do it, engineers would have to tunnel through the adapter’s exterior by removing some of the outer panels of the adapter to get to the PDU. The panels weren’t designed to be removed this way, but this scenario may only take up to four months to complete if engineers figure out a way to do it.

A third option is that Lockheed Martin and NASA could fly the Orion capsule as is. The PDU failed in such a way that it lost redundancy within the unit, so it can still function. But at a risk-averse agency like NASA, flying a vehicle without a backup plan is not exactly an attractive option. It’s still not clear what went wrong inside the unit, which was tested before it was installed on the spacecraft, according to a person familiar with the matter.



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

... not their worst clusterfuck ...



Yes, it really happened.

It took place at the Lockheed Martin Space Systems factory in Sunnyvale, California. As the team was turning the satellite into a horizontal position, they found out that the twenty-four bolts that were supposed to hold it in place had been removed by a technician - and the action was never documented. ...

—-  SpaceX private astronaut launch debut to reuse Crew-1 Dragon spacecraft
November 30, 2020
Quote
A former NASA astronaut now employed by Axiom Space says that SpaceX’s private astronaut launch debut will reuse the same Crew Dragon spacecraft currently supporting NASA’s Crew-1 mission in orbit.

Currently just a few weeks into a planned six-month stint in orbit, potentially marking the longest uninterrupted flight of an American spacecraft ever, Crew Dragon capsule C207 and an expendable trunk section arrived at the International Space Station (ISS) on November 16th. Known as Crew-1, the mission represents SpaceX and NASA’s commercial operational astronaut launch debut, carrying four astronauts to the ISS.

Crucially, the mission has been an almost flawless success so far and Falcon 9 has now completed four Crew Dragon launches without issue. On the Dragon side of things, the Crew-1 spacecraft performed a bit less perfectly than those tasked with flying Demo-1 and Demo-2, but SpaceX handled the minor issues that arose with the professionalism and composure of a team far more familiar with human spaceflight.

God willin’ and the creek don’t rise*, I’ll be leading the Ax-1 crew on the first purely commercial orbital mission in history a little over a year from now – on this very SpaceX Crew Dragon capsule. It’s gonna be a #Blast !

SpaceX drone ship Of Course I Still Love You (OCISLY) has departed Port Canaveral ahead of an upgraded Cargo Dragon spacecraft’s Falcon 9 launch debut.
Scheduled to lift off no earlier than (NET) 11:39 am EST (16:39 UTC) on Saturday, December 5th, SpaceX’s 21st NASA Commercial Resupply Services (CRS) launch will mark several major firsts.

It will also be the first time in history that a new spacecraft has debuted on a flight-proven rocket, as well as NASA’s first flight on both a twice-flown and thrice-flown Falcon 9 booster. If CRS-21 is a sign of things to come, life will be made much easier for SpaceX, reducing or eliminating the need to operate separate booster fleets for commercial and institutional customers.

Finally, CRS-21 will also mark the first time in history that two SpaceX Dragon spacecraft have been in orbit – or at the ISS – at the same time. A senior SpaceX Dragon manager recently noted that after Crew-1’s successful November 15th launch, all future Dragon launches would leave the company with two Dragons in orbit. …

Space station to receive new commercial airlock from Nanoracks
Quote
In addition to roughly three tons of fresh food, supplies and experiments for the space station’s seven-person crew, the Dragon cargo craft will deliver the first commercial airlock module to the orbiting outpost.

“This is the going to be the first commercial module for the International Space Station, designed and built here at Nanoracks,” said Brock Howe, the company’s project manager for the Bishop airlock. “We’ve been working on the airlock for about five years.”

The bell-shaped module is about the size of a small closet, measuring 6.9 feet (2.1 meters) in diameter and 5.8 feet (1.8 meters) long. Its dimensions were constrained by the size of the trunk on the Dragon cargo ship, the only spacecraft capable of ferrying large external payloads to the space station.

“If the volume (of Dragon’s trunk) was an inch bigger, our airlock would be, too,” said Mike Lewis, chief innovation officer at Nanoracks. “It’s big enough for people to climb in it.”
Nanoracks will use the airlock to move equipment into and out of the space station, expanding on a similar capability currently provided by an airlock inside the Japanese Kibo lab module

The airlock in Japan’s Kibo module works with a slide table, where astronauts can position equipment for transfer outside the space station.
“The Kibo airlock can transfer a piece of equipment about the size of a microwave oven, whereas this new Nanoracks airlock that we’ve been building will be able to handle something on the size of about a refrigerator or freezer. So it’s about five times the size of the Kibo airlock.” …

NASA considering commercial Mars data relay satellites
December 5, 2020
Quote
WASHINGTON — A constellation of commercial satellites could serve as a communications relay system for future NASA missions, such as an orbiter later this decade to search for subsurface ice there.

In recent presentations to advisory committees, NASA officials have discussed the possibility of working with industry to place several satellites into orbit around Mars that would serve as relays for other missions, notably the proposed Mars Ice Mapper. Such satellites, they said, could greatly increase the amount of data missions can return to Earth and end reliance on aging science missions that also serve as data relays.

One proposal presented at those meetings features three satellites in equatorial orbits at altitudes of 6,000 kilometers. The satellites would be equipped with radio links for communicating with other spacecraft in orbit and on the surface as well as to and from Earth. The satellites may also include laser intersatellite links to allow them to communicate with each other.

“This will be an opportunity to provide great relay assets” for various Mars missions, said Eric Ianson, director of the Mars Exploration Program at NASA Headquarters, during a Nov. 30 meeting of NASA’s Planetary Science Advisory Committee, or PAC.

That constellation, he said, would be a “commercial contribution” of some kind, although the exact nature of the arrangement between NASA and industry had yet to be worked out.

Davis said a communications system like the one proposed could increase the data returned from Mars by a factor of 100, which would be valuable for Mars Ice Mapper, whose radar will generate large volumes of data. “That is revolutionary, potentially, in terms of being able to flow total data and also being able to do time histories of things we’re looking at,” he said.

In addition, he noted a communications network at Mars would mean future missions would not need their own powerful direct-to-Earth communications systems, and can instead fly with smaller and less expensive systems that can work with the data relay satellites. “We see significant dividends for the science community going forward that really opens up an envelope of opportunity that we have not had before with Martian exploration.” …

From hops to hopes – Starship SN8 set to advance test program into the next phase
written by Chris Bergin December 7, 2020
Quote
SpaceX’s Starship Prototype test program is set to make its next leap forward as early as Tuesday, with SN8 tasked with a 12.5 Kilometer test flight – and a landing attempt – at the company’s facilities in Boca Chica, Texas. The window opens at 9 am Central.

Successfully landing Starship SN8 has but a slim chance of being achieved. However, data from the flight – and the potential of a controlled descent – would provide vital data to be fed into a fleet of follow-on tests, starting with the next Starship, SN9, which is all-but ready to roll once SN8 has vacated the launch mount.

The option to conduct a final Wet Dress Rehearsal (WDR) was taken on Monday, which proceeded without issue.
The test flight’s target date did slip from last week through to Tuesday, initially relating to weather conditions. Approval to conduct the test was already provided last week, with documentation showing the 15 KM altitude target and a local exclusion zone.

The test was originally targeting 20 KM, before being reduced to 15 KM and most recently to 12.5 KM. The latest altitude reduction is understood to be related to high altitude winds as the vehicle translates from its powered ascent into the bellyflop return utilizing its aero surfaces.
This remains the key objective, should SN8’s trio of Raptors successfully loft the vehicle to its target altitude.

Then, for the first time during Starship testing, the aero surfaces will come into play, as SN8 glides/descends – or, as many like to word it, bellyflops back toward terra firma.
This phase of the test will be a major data point for SpaceX, allowing them to recreate what they’ve already evaluated in a wind tunnel in the more challenging regime of real life.

Should SN8 remain under control during the return, the next major milestone involves a Raptor relight to push the vehicle vertical via the use of the Thrust Vector Control (TVC) system. As SN8 swings her aft toward the ground, the TVC will point the nozzles and direction of thrust to aim the aft at the landing pad.
Any subsequent “wobbly landing” would be something that could be refined via the data gathered during SN8’s attempt.

“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,” added Elon in subsequent Twitter replies.
Of course, Elon also provided the hopefully-unlikely scenario of SN8 failing as she leaves the pad.

Although the most likely failure point is expected to be during the attempt to return to the landing zone, the ability to drop SN8 into the sea – should the return trip not go to plan – is also available.
“Although, if it fails right at the end, some landing pad repair will be needed to fill in the crater,” Elon added.

Should SN8 land without issue, this would undoubtedly be an astonishing success, achieving numerous firsts and allowing for an acceleration of testing to higher altitudes. …

It was a good test - it would have spot the landing if it had another 500 ft and and a little less delta V ...

Reminded me of the ending to Koyaanisqatsi a little ...

Not having all Raptors firing during the entire ascent was a surprise.  Landed vertically, right in the middle of the landing pad, just with too much speed.

Amazing controlled bellyflop, reorienting to vertical just before touchdown.

SpaceX: On Wednesday, December 9, Starship serial number 8 (SN8) lifted off from our Cameron County launch pad and successfully ascended, transitioned propellant, and performed its landing flip maneuver with precise flap control to reach its landing point. Low pressure in the fuel header tank during the landing burn led to high touchdown velocity resulting in a hard (and exciting!) landing. Re-watch SN8's flight [below].

Starship *SN9* is almost finished, and could fly within weeks!

Here’s SpaceX’s vid, should be cued at 1:47:44, 30 seconds from liftoff.

On top of all the amazing firsts of SN8’s flight is that these outdoor rocket construction techniques, with a new type of rocket engine that has never been flown before (except for Starhopper, SN5 & SN6), and in existence for just the past few years…

…is now begging the question of whether Starship/Superheavy might get to orbit before the expendable SLS, which has been in the works for ten years and is re-using actual rocket engines from the Space Shuttle (not copies) and extended shuttle solid rocket boosters.

Also that the Falcon 9 method of “flamey end down” booster descent and landing for reusability, which the industry is scrambling to duplicate or be rendered obsolete, is soon to be replaced with a “pointy end sideways awaiting last-moment engine relight and attitude switch” descent and landing, for full and rapid spacecraft reusability.

Sigmetnow,  Can starship reach orbit and then slow down and simply fall back to earth ? We see standard rocket re-entry with lots of friction and heat , does the starship fall slowly enough to avoid heat or any worries about burning up. I would think at very high altitudes there is very little air and falling speed would be very high.

Btw, The comments on the YouTube about the SN8 launch are very funny.

Without superheavy booster and without payload and without fuel to return, starship can just about reach orbit, but what would be the point.

With superheavy booster to help getting to orbit then you could 'stop' but again what is the point?

Orbit means travelling fast. Slowing to a near stop is just too wasteful of fuel. The aim is to use as little fuel as possible to slow down and land so you want to use the atmosphere as much as possible to slow down, hence the desire to travel sideways on, so the atmosphere can do more of the slowing down.

Starship will need a (more of a?) heatshield on one side to avoid overheating on reentry in this sideways on manner. Stainless steel is good at coping with heat but it would get too hot and lose structural integrity without heatshield.

I have wondered about sideways on and rolling along main axis so no one part gets worst of heating without some time on the leeward side to cool down again. Doubt human passenger would enjoy that though. The flaps as they are are undoubtedly better than my daft ideas.

Striking about today's Sirius XM-7 launch: This will be the 7th flight of this Falcon 9 core. No other purely commercial mission has flown on such an experienced booster before. Most have gone on the first or second Falcon 9 flights.
https://twitter.com/sciguyspace/status/1337419583586766851
~ This likely means either:
a) Sirius got a substantial discount on this launch.
b) Customers are becoming more comfortable with flight-proven rockets.
Or both!
