totm dec 2023 Artemis Discussion Thread

[SunlitZelkova]

I watched the Artemis II crew on The Late Show With Stephen Colbert. When asked why we are going back to the Moon, Wiseman said “because we want to see humans on Mars.”

It’s crazy that the Integrated Program Plan’s vision lives on 50 years later and forms the basis for a 21st century space agency’s roadmap.

Is he joking? There are only robots there. Whom is he going to see?

He will take a mirror with him

Donald Thomas was invited to participate in the Space Day in China. He then gave a presentation on the Artemis missions. He said Artemis 3 manned mission to the moon, with launch delayed until 2026.

As expected.

Was this announced in the US prior to this?  Was expected, but was it officially announced?

I think it was 2026 2025.

From last year (I agreed then, and he's right again):

 

Artemis II is Nov 2024... Q4 generally means the next year, lol. 2025 has not been a thing for III for a while.

Cautious and deliberate engineering that meets or exceeds all its test objectives is SOOO last-century.

Never been to Stennis myself, but I have former coworkers who have been there. Rolls-Royce now does their noise testing there.

To be fair, those engines are also last century—and each one of them likely costs about as much as an entire Starship/Super heavy stack (the first 4 Artemis missions use engines refurbed at a cost of $128M each, on top of what was initially paid for them last century, ~$40M then, which is likely ~$80M in 2023 dollars).

NASA high-speed film footage of Artemis launch. Combined into an absolutely magnificent edit with a banger tune:

 

[Barzon]

NASA Selects the Blue Origin Team for Astronaut Mission to the Moon | Blue Origin

Height: 16m

Diameter: <6.2m

Dry Mass: 16t

Wet Mass: 45t>

4 crew capable, anywhere on the Moon, day or night.

Cargo config can do 20t reused, 30t expendable.

Basic CONOPS are that it launches to LEO, flies itself to NRHO, then the cislunar transporter is launched to LEO on New Glenn and refuelled, and flies to NRHO to refuel Blue Moon. It can stay in NRHO as needed, or return to Earth orbit.

 

[tater]

This is a great design.

People will compare, and I have already seen poorly done versions, so here's a decent one.

Source Selection Statement is out - https://www.nasa.gov/nextstep/humanlander4

Notably, Blue have pathfinder landing flights planned for 2024 and 2025, and their HDL proposal significantly exceeded both mass and volume requirements.

Dynetics, however, didn't account for cargo or an EVA suit, so it was uncertain whether they would meet the 4 crew requirement.

I have my doubts about 2024, but it would be awesome to see something, anything, light a fire under them.

2024 is... very much possible.

Even if they manage to launch NG in 2024, it's not like they will recover (even if they try), then reuse in time to land on the Moon the same year.

[tater]

Apparently during the actual announcement (with people talking), they said first flight was 2030, test flight a year before that.

In case people don't know, that's Mars from Holst's Planets Suite.

I went to an interesting performance of the Planets at Seattle Symphony one time where the orchestra played the music and they had a huge video screen set up showing real-life pictures of the planets from various space probe missions.

Dynetics Couldn't take the lawyers 

Will still be cool to see it in action 

Spoiler

The ladders also gone thank goodness

Dynetics could not make the math close. They always had an issue with needing some sort of physics cheat code to get the thing to land and still be able to come home—first with just 2 people, now with the required 4.
