I wanted to say (but seemingly failed) "60 years of technological advancements since Apollo early days, 1962"

The upgrade path of STS propulsion is a great 👍 spaceflight discussion topic.

But it's off-topic in this thread.👎

I deleted such posts.

At 1h40m of this video, Jim Free says that there will be a control center at JSC (the hub), one for the HLS provider and one for SLS.

Some of the highlights from the Explanatory Statement: [...]

Quote from: page 134 of the Explanatory Statement
Human Landing System (HLS). -The agreement provides not less than $1,195,000,000 for HLS, including no less than the requested amount for the Lunar Lander office. With these funds, in addition to enabling a human landing during the Artemis III mission, NASA is expected to make real investments in development that promote competition for the sustainable lander phase rather than additional studies. The agreement urges NASA to enable a routine cadence of human transportation services to and from the Moon with multiple providers, as practicable. Within 30 days of enactment of this Act, NASA is directed to deliver a publicly available plan explaining how it will ensure safety, redundancy, sustainability, and competition in the HLS program within the resources provided by this Act and included in the fiscal year 2023 budget request. NASA shall also provide to the Committees a description of all resources needed in fiscal years 2023 through 2026 to accomplish these goals.

I think that this is a more reasonable request that what Cantwell was asking in the NASA Authorization bill. LETS essentially needs three things to go forward:

1- The FY22 CJS Appropriations bill needs to be passed by Congress (which should happen early next week).

2- The FY23 Budget needs to come out (it is expected to come out in mid-April but it was actually due in early February). According to Nelson, the FY23 President's Budget is expected to have the budget for two HLS providers (so I am guessing a budget for HLS of about $2B per year). Once that happens an RFP for LETS should come out.

3- The FY23 Budget request for HLS needs to be enacted by Congress (I am guessing in early 2023). Awards for LETS are likely to be made once that the FY23 Appropriations bills are passed. The number of LETS awards will depend on how much is enacted for HLS in FY23.

Heyo, that’s a depot!

Great pics of the elevator mockup – have these been published prior?

StarshipTrooper · « **Reply #3368 on:** 03/11/2022 08:34 pm »

I wonder how they move the elevator out of the lunar starship and onto the vertical rail? They probably won't use a big vertical I-beam on the lunar starship, so this must be a rough prototype.

It looks like they push it? I have attached my quick and dirty interpretation of the four "suited" elevator training images.

Top right image: Pushing/pulling the elevator in/out using the handle (blue in my schematic).
Bottom left: Locking the rail (red) in place.
Top left: The elevator can then be boarded and descend along the rail.
Bottom right: Lowering the front gate/ramp and exiting.

Reverse the procedure for ascent and entry.

No but there was this other picture of the elevator from a prior presentation.

This new "elevator cabin" looks very much like the "payload dispender" we have seen this days at BC.

No, these are not the same at all. The dispenser has no floor, is not configured for a central lowering tether, and is curved on its ends to ride within the 9m hull diameter.

Interesting image in the NASA video of two Starships at Gateway. The one that is departing is HLS. The other ones seems to be a regular Starship.

As you can see from top right corner, it's NOT an official render (although interesting that NASA use one)

Please no misinformation (tbf the ability of David Willis to research before posting is questionable anyway)

NASA often (usually, in my experience) uses contractors for rendering even official stuff.

It's not even a very good render. The PPE / HALO modules don't look like that.

Yes, I was thinking that also. It goes to show that not much thought was put into this. They probably just used an existing clip and asked for permission from the authors of the clips.

Yeah, I agree now it’s not official.

They must have asked for permission. I found the twitter account of Deep Space Courier:

Doesn’t look like a usual rendering contractor. Agreed, then, that it’s not official unless we know NASA commissioned that YouTube channel.
