#NASA #NAC #HEO -Next-

#NASA #NAC #HEO - Going over the plan for the #Artemis1 mission. Was a successful mission design

#NASA #NAC #HEO - Amit Kshatriya - What I was really thinking about were all about the US businesses that put thier hands on that hardware, sometimes "Mom & Pop" shops. Just how many of them contributed to the success.

#NASA #NAC #HEO - Every dollar that gets pulled out of the treasury gets put back 3x. Hale - Whoever put those engineering cameras on Orion was amazing!

#NASA #NAC #HEO - List of accomplishments for #Artemis1, MECO Targeting was phenomenal, the longest burn of an RL-10 engine, we got what we paid for in terms of an integrated test, had quite a bit of margin thermally & end-to-end recovery with the Navy.

#NASA #NAC #HEO - Started evaluation when the vehicle came back, had some odd behavior with the nozzle plume and some data on the heat sheild, we don't pre decide what we're going to do, want a fundamental understanding of the issues 1st.

#NASA #NAC #HEO - also looking at some odd behavior that was exhibited by the service module.

#NASA #NAC #HEO George Sowers asking about the environments Acoustics and such, A: VERY well.

#NASA #NAC #HEO - For #ArtemisII we're going to be VERY careful, will fly around Earth for a few hours to get the ECLSS squared away and the crew settled, then will target a free return. Transit s/b 2-3 days.

#NASA #NAC #HEO Major milestones for ArtemisII -

#NASA #NAC #HEO - Our main priority is the crew. They have started thier training and have very high confidence in the team training them, Highiest priority is to get the crew around the Moon and home to their families.

#NASA #NAC #HEO - On SLS Core: will hold the core until the October timeframe. Don't need it to stack until February time frame. Everything is tracking currently well for the November '24 timeframe.

#NASA #NAC #HEO - Hale: On Damage to ML 1, any debris concerns? A: Is everyone Satisfied? No, Charlie Blackwell Thompson is leading a study now on the debris that came off.

#NASA #NAC #HEO - Artemis III - first landing attempt Will insert into a Near Rectliniear Orbit. The plan is to do a direct dock with the SpaceX lander. have the crew transfer to the lander, land and conduct operations, and return home.

#NASA #NAC #HEO - need to conduct dual launch campaigns with the Super-Heavy & SLS. Artemis III will be a significant challenge.

#NASA #NAC #HEO - Landing site selection, started downselect of this, almost all science-driven, will look at lander ablities, and can we get to a spot that is in the performance box. Return of volatile samples is key to us.

#NASA #NAC #HEO - Hale - Is VIPER still on track to get there before you do? A: Yes it will be long enough to know what we need to do to retool our landing.

#NASA #NAC #HEO - SM 3 will ship the latter half of this year. Orion this will be the 1st time we do a docking. Building heritage from the ISS, same design on the Starliner. SLS Core 3 is back at the factory. Stage adapters & SRB's ready by summer.

#NASA #NAC #HEO - On the Ground Segment side, want to understand the refurb for the ML's then we start moving into the HLS, working very hard, On the flight at Boca got to 39 KM. There are some regulatory issues that kicked in.

#NASA #NAC #HEO - SpaceX is an integral partner got to look at the ECLSS for the lander. Have a team of people that are engaged with them now. Assisting with how to interpreting the data.

#NASA #NAC #HEO - Hale On Apollo, the lander was the pacing item, I suspect that will be the same thing here. A: We really want to fly this mission as we planned it but the key is to keep flying, we will choose missions on the hardware that is available.

#NASA #NAC #HEO - George Sowers - This will be the last ICPS? A: Yes.

#NASA #NAC #HEO - Interfaces between the suits and Orion and Suits and the lander, things are moving along hardware flying all over the place.

#NASA #NAC #HEO For #ArtemisIV - Will start construction of Gateway, Orion will take the iHAB out, will mate the iHAB to the power element and enter into the iHAB, then Orion returns, Brings Heavy lift out at the pad.

#NASA #NAC #HEO - SLS: Finished CDR on the Upper stage, Put the Universal stage adapter, looked at it and it's HUGE. Bectel building the primary structure on ML-2 design review complete, expect the tower to begin construction by end of the summer.

#NASA #NAC #HEO On HLS side we'll get out of the "alphabet soup here" and will get the lander ready

#NASA #NAC #HEO - Will have a second provider for #ArtemisV. Have eyes out as far as #ArtemisVI for engines and have cycles out for Missions IV, V, & VI. Hale asking on on when you run out of Shuttle Heritage engines. A: Think Artemis V for RS-25's and for STS OMS Engines.

#NASA #NAC #HEO On Flight Projects: A lot of the investment is in exploration capabilities, a lot of these projects have been invoked in LEO. On ISS seeing water reclamation at 99%, for a Mars mission need 98%.

#NASA #NAC #HEO - Presentation completed.
