.@NASA_Orion is aboard the USS Portland and is making its way to Naval Base San Diego. It is expected to arrive onshore on December 13th with offload on December 15th

Didn't know they were going to do this, very interesting.

Orion capsule bounces off atmosphere to complete hottest and fastest reentry ever, capping off NASA's Artemis 1 mission

The capsule intentionally skipped like a stone off the atmosphere to make its reentry easier.

www.livescience.com

As far as I know Apollo-11 did use the skip reentry profile.

On another note on tonight's six o'clock news in the article on the completion of Artemis-1's mission it showed time-lapse photographs showing the separation of the CM from the SM.

9 posts above (earlier than) yours is a list of spacecraft that used a skip re-entry profile.

My bad, I never thought of it as a "skip".

But apparently that's what everyone calls it...

Pegasus, @NASA's barge, delivered the engine section for #Artemis III to @NASAKennedy on Dec. 10. The barge ferried the SLS hardware from #NASAMichoud, where it was manufactured, to Kennedy where teams will finish outfitting it. Check out some images from its journey!

That was pioneered initially by the Gemini spacecraft CMs IIRC.

On another note I stumbled across this Timelapse video from Artemis-1:

I hope a book is written on the people behind this from the perspective of those who worked very hard while suffering abuse from trolls. The Garvers have had their say. Time for the makers to have the floor.

Let's wait first for them to put ppl on the moon. The story will then be even more fascinating (and make more sense).

I stumbled across this short video from NASA concerning the origins of the Moon (The Moon-rock samples brought back by the Apollo Moon missions had a big role in this):

 

[TomS]

I wonder what all of those little weird white square patches are scattered around the upper heat shield are?

I think it's basically the tape that held the mylar film onto the shell. The mylar mostly burned off, but the tape seems to have held up better.

I am surprised at the at as well NMaude, I thought that they should have shown the Orion CM separating from the SM too. Let's see if they do that for Artemis 2.

 

[NMaude]

I'm surprised because when the successful reentry was reported on the six o'clock news the NASA supplied footage included a shot showing the Orion CM separating and then immediately manoeuvring away from the SM.

I stumbled across this interesting video uploaded onto YouTube four days ago comparing the trajectories of Apollo 8 and Artemis 1:

 

[publiusr]

What a long strange trip it’s been….fitting though…since NASA itself has been on Walkabout for so very, very long.

 

[NMaude]

since NASA itself has been on Walkabout for so very, very long.

It's been a long road .

 

[FighterJock]

Will NASA do the exactly the same trajectory with Artemis 2 as what they did with Artemis 1?

 

[TomS]

Will NASA do the exactly the same trajectory with Artemis 2 as what they did with Artemis 1?

No. Artemis 1 was testing some elements for future deep-space flights. Artemis 2 is supposed to fly something more conventional.

The @NASA_Orion spacecraft has arrived back at @NASAKennedy in Florida after an 1.4 million mile mission beyond the Moon and a cross-country truck ride from Naval Base San Diego in California.

Artemis I Orion Spacecraft Returns to Kennedy Space Center

After its 1.4-million-mile mission beyond the Moon and back, the Orion spacecraft for the Artemis I mission arrived back at NASA’s Kennedy Space Center Dec. 30. The capsule splashed down in the Pacific Ocean on Dec. 11 and was transported by truck across the country from Naval Base San Diego in California to Kennedy’s Multi Payload Processing Facility in Florida.

Now that Orion is back at Kennedy, technicians will remove payloads from the capsule as part of de-servicing operations, including Commander Moonikin Campos, zero-gravity indicator Snoopy, and the official flight kit. Orion’s heat shield and other elements will be removed for extensive analysis, and remaining hazards will be offloaded.

Artemis I was a major step forward as part of NASA’s lunar exploration efforts and sets the stage for the next mission of the Space Launch System rocket and Orion to fly crew around the Moon on Artemis II.

Good to see the Orion capsule back at Kennedy.

 

[NMaude]

NASA has posted a short video about the anthropomorphic test-dummy used on Artemis 1:

The Purposeful Passengers consist of one manikin and two phantoms that flew aboard the Orion spacecraft during the Artemis I mission in order to collect important data that will prepare astronauts for future Artemis missions. The manikin was used to study vibrations and accelerations during the flight and was named Commander Moonikin Campos after NASA held a public naming contest in June 2021. The name "Campos" is a dedication to Arturo Campos, a Mexican-American electrical engineer who worked for NASA’s Johnson Space Center and contributed to the rescue of the Apollo 13 mission and crew.

 

[NMaude]

The latest TW@N video has some news about the Artemis-1 CM:

The Orion spacecraft is back in Florida after Artemis I, a direct deposit on Mars, and an insightful mission comes to an end. These are a few of the stories to tell you about – This Week at NASA!

 

[publiusr]

Good thing I wasn’t driving the truck…I would have done a Twitter and dropped the capsule in Elon’s parking space at Boca.

Let that sink in.

Apparently they are currently stripping the relevant equipment out of Artemis 1 that will be refurbished and subsequently fitted into Artemis 2.

 

[Conspirator]

Apparently they are currently stripping the relevant equipment out of Artemis 1 that will be refurbished and subsequently fitted into Artemis 2.

seems quite cost effective that way. however i would like to know what equipment specifically they are "refurbishing" it does reduce costs because of this.
(they were already past their budget on the launch of ARTEMIS1)
i would think its most of the interior avionics systems and computers.
but how big is the cost difference? maybe a couple million?

Alan Ladwig stated that they will continue this practice to the point of reusing the pressure capsule from ARTEMIS 3
seems a bit risky due the the stress from pressurizing and depressurizing but plausible.

I think it was mostly a politically driven decision to placate congress over costs back in the day.

Not if the Orion CM is designed to be reused.

Why would this be risky? No one accuses the Dragon crew capsule of being risky, despite going through multiple cycles like this over its life.

 

[publiusr]

Besides-capsules are a tad closer to diving bells-or pressure spheres on old airguns-than are most airframes. I even wonder if a capsule may be a bit of a threat to lighter, weaker dedicated dry station tubes over time. The capsule is rugged to survive aborts. ET stations withstand SRBs. Dry tube modules-being cylinders...

how many trips has one of those capsules endured? (without any reconstructions/overhauls?)
i'm sure there is at least some concern over this. the only details i could find on this particular subject are quite vague and unclear. I'm also unsure of the number of capsules that have been completed and launched in total. (i'm sure there is more than one)

the capsule endures immense stress from the change in pressure on the inside and out. so of course they have to design it to withstand these kinds of changes. but how long or how many trips could it safely do without serious concerns/issues arising?
its merely a safety concern on my end.

"Without any reconstructions/overhauls" is a pointless caveat, because Dragon goes through a rebuild/refurbishment process between flights, and so will Orion.

Obviously, there are "concerns" about reuse" in the sense that NASA and SpaceX have taken care to make sure it is safe to reuse the capsules. But it's not considered any more "risky" than any space launch. And probably less, in the same way that flight-proven Falcon 9 boosters seem to be at least as reliable as new ones.

There are four active Crew Dragon capsules (and one more, C213 under construction). At least one of these (C206) has made three flights. SpaceX and NASA are sufficiently confident in their lifespan that SpaceX is not planning to make any more Crew Dragons after C213, despite having contracts to fly them for many more missions. SpaceX estimates 15 flights each, with refurbishment mainly of expendables like parachutes.

There are also a number of Cargo Dragons that have pressurized capsules. The current ones are based on the same Dragon 2 design as the Crew Dragons and are intended for at least five flights each and one has already flown 3 times (C208). Several of the older Dragon 1 cargo capsules also made three flights before being retired in favor off the more modern Dragon 2 versions. I've seen no indication that the retirements were for safety, just that the new ones are easier to refurbish and thus cheaper to fly.
