NSF Live: SLS prepares to rollout, SpaceX stacks Booster 7, international relations update, & more

[lesumsi]

This is the only live video series on YouTube, where I make sure to watch the recording, if I can't make it in time! Thanks NSF!

[johnschilling]

Chris Gebhardt and John "Das" Galloway are captivating and thoroughly entertaining while delivering a plethora of quality information in a 90 minute YouTube segment. Thank You Guys for all that you bring to the table in every NSF Live channel post - cheers!!

I was watching the Starlink 4-9 (v1.5) launch in person with my sister and after the launch we were walking back to my car and i told her wouldn’t it be funny if we saw a NasaSpaceFlight person here? And not even 5 seconds later i heard a very familiar voice and i look up and it was Chris G commentating! I didn’t want to interrupt him since he was talking but hey it was super cool seeing someone that i have only seen online before!

I really like the precision with which Philip Sloss articulates. Nice addition!

[welshbordergirl]

Yay, can’t wait for an SLS Stakeout stream! 🚀

[LanghamDesigns]

Loving the launch chatter! Thanks fellas 🧡🚀

If SLS sees its shadow, does that mean 7 more years of development?

[davetremaine]

Philip Sloss, thanks for the heads up to tune out. Dude's talks like grass grows.

Taxi to the stars 🤞🏼it’s a clean mission

I don't think they said that the stage spinning was not from blowing through the fairing. I think they just said they were not able to correct it, though they would have if things were working as expected. Have to imagine that blowing through the fairing added some unexpected motion on the stage.

1:29:30 Maybe they are wanting arms that cannot interfere with grid fins. Maybe the new ones will sit lower.

The Link to that doc on screen at the end is not available because chat replay is disabled. Could you Post and pin it here please.

this is don't stop building this at all bro I'm really looking forward to the starship being finished

[chyraxion]

if an orbital flight happens this year of starship id be really surprised, i mean they still haven't fired more than 3 regular raptors at a time, the tank farm is still not finished, seem to be having issues with the tower rails for the skates, lots of valves and plumbing was removed from the olm, the timeline is slipping worse than usual, those 2 vertical methane tanks were a major setback as well and a major oversight

[andrewbeeco]

Are they going to forcefully delay starship until SLS launches for positive or?

While it can be argued that right now, March 2022, there is nothing competitive with the SLS, in that there is nothing else powerful enough to deliver an Orion capsule to Lunar orbit, that will not be true in May 2024, 26 months from now when the first operational flight is scheduled. By the end of 2022, Starship will be capable of carrying the entire Interim Cryogenic Propulsion Stage (ICPS) plus its payload to the planned initial 0 x 1, 791km elliptical orbit. The ICPS masses 31, 000kg is 13m tall and 5m and the Orion CM with the ESM is 26, 000 kg and 7.3m tall. That is a total payload of 47 tonnes and height of 20.3 m, which is technically just over the current announced height of the Starship payload bay, but SpaceX is already considering stretching Starship, and the ICPS and Orion do not require an external fairing. The Orion Launch Abort System is not necessary because the Starship itself should be capable of escaping a booster failure, especially in the version with 9 engines. Starship could probably even deliver a fully loaded Exploration Upper Stage (EUS) with Orion. I cannot find a total mass for the EUS, only its fuel capacity of 129 tonnes, suggesting a wet mass of about 142 tonnes so the total mass required for the planned Artemis IV mission, four years from now, would be about 170 tonnes. For the low-inclination initial orbit that is probably within the capacity of current Starship prototypes, and will undoubtedly be well within the capacity of production Starships in four years.

The only point of the Artemis I mission this year is to collect the information necessary to ensure the safe completion of Artemis II. If it will not make sense to use SLS to launch Artemis II, there is no point in launching Artemis I, and absolutely no point in continuing to spend anything on the subsequent missions.

russia was making moves for months b4 hand to say its purely a coincidence is silly

[aneubeck]

How is everyone so excited for sls when it’s basically all the technology from a 50 year old rocket? That’s like the lamest thing I could ever imagine.

[hanswichmann]

TOO funny how they try not to break up as Chris's green screen software STB's!!! Good info though, just don't watch!! lol.... love you guys...

I can't believe they're actually going with the elevator for lunar Starship.. it's such a clunky and risky solution. A much more Elon idea would be to land on the moon upside down, with falcon-style legs built into the nosecone. Since they will almost certainly have to use landing thrusters rather than raptors for landing and takeoff there is no reason to land engines-down. Astronauts and cargo would be right next to the lunar surface, just a small ramp would be enough for cargo unload. Having the legs in the nose would increase commonality between starship variants as aft-skirt would not need to be redesigned, and could achieve a much larger footprint for stability as opposed to stubby legs seen in initial renders.
