The Crew Dragon Endurance spacecraft for NASA’s SpaceX Crew-5 mission arrives at the hangar at Kennedy Space Center’s Launch Complex 39A in Florida on Sept. 23, 2022. The capsule arrived at the launch complex after making the short journey from its nearby processing facility at Cape Canaveral Space Force Station. NASA astronauts Nicole Aunapu Mann, commander; Josh Cassada, pilot; and mission specialists Koichi Wakata, of JAXA (Japan Aerospace Exploration Agency), and Roscosmos cosmonaut Anna Kikina will lift off aboard Endurance – on the company’s Falcon 9 rocket – from Launch Complex 39A at Kennedy. Liftoff is targeted for no earlier than 12:46 p.m. EDT Monday, Oct. 3. Photo credit: SpaceX

Good news for Hermes fans: the full-scale ESA mockup at the Musee de l'Air et de l'Espace at Le Bourget is in the repair shop!

Do we have even rough ideas of a timeline for Polaris 2?

Will Polaris Dawn slipping back 3 months likely push it back as well?
24
Why not Terran (specifically vs ABL - Firefly's prior launch attempt I can see making them more likely)?

Missions To The Moon (HSF) / Re: Artemis 1 Discussion Thread

Last month NASA posted:

Quote from: https://www.nasa.gov/feature/artemis-i-mission-availability
November 12 – November 27 (preliminary)

12 launch opportunities

No launch availability on November 20, 21, and 26

December 9 – December 23 (preliminary)

11 launch opportunities

No launch availability on December 10, 14, 18, and 23

Also, any windows prior to 11/22 are night launches.  NASA may be leaning toward a daytime launch, especially for the maiden flight.

A daytime launch is desirable, but not required by NASA. They DO require that Orion splash down in daylight.

Rocket Lab / Re: Rocket Lab Neutron rocket - Discussion

Awkward at the least that RL focused on a few things that would allow them to out-compete the market leader, and is now walking them back one by one.
27
It could mean a bunch of other things, like readiness of the Starlink direct laser comms system or the vacuum stability of the interior, etc.

... But helium isn’t hazardous except as it displaces oxygen, and there are oxygen sensors all over the place, plus they can use mobile ones. ...

But how do you test for helium leaking into a cavity being purged with helium?
Ah, I see. You can do it by monitoring how much helium you’re putting in and how much comes out.

Difficult. Not purging the cavity with helium during leak testing would seem more likely.
Yup, but if you purge with, say, N2, you can get condensing (or freezing?) LN2 on places that get cold enough.

It’s a health and safety risk, and I’m getting very frustrated with this kind of reckless argument by some folk at HQ who ignore these concerns with the opposition class, short-stay diktats.

Basically, the plot of The Martian would go like this:

The bad news is I'm stranded on Mars. The good news is, I have tons of food and an excuse to watch the Lord of the Rings director's cut.
