AckSed Posted September 28 Share Posted September 28 The 'trunk' also being a berthing mechanism/docking port may also be a bit of future-proofing. Say Orbital Reef becomes a thing and they decide an expanded ring is more optimal. Redesign the trunk, a solid rocket booster extra and away you go.

It is a shame to put mass in orbit only to deorbit it to destruction shortly after. What if the DC and Dragon trunks had enough extra RCS and some code to slowly rendezvous and dock (or somehow more simply aggregate) together in orbit over time awaiting usefulness? There would be no rush so it could be very efficient and they could simply rz with the nearest viable cluster of spare parts Quote Link to comment Share on other sites More sharing options...

AckSed Posted October 4 Share Posted October 4 Sierra Space working on storing and dropping supplies from orbit for the Air Force: https://spacenews.com/the-air-force-is-exploring-the-potential-of-space-vehicles-to-rapidly-transport-critical-supplies-from-orbital-warehouses-back-to-earth/ Quote Link to comment Share on other sites More sharing options...
Nuke Posted October 4 Share Posted October 4 i dont know if using orbit as ammo dump is a good idea, orbit such an asset over a hostile country and they are probibly justified firing their asat weapons at it. you are better off with point to point rockets that are more unpredictable and harder to intercept.

Good point. Ammo isn’t the only thing people need though. MREs, medical supplies, spares etc also. Point to point does seem more logical. One wouldn’t have to wait for the depot orbit to cross close to the LZ for one thing. Disaster relief might be a better use case than war. But I suppose “war” is a subset of “disaster”, so… Edited October 4 by darthgently Quote Link to comment Share on other sites More sharing options...
AckSed Posted November 8 Share Posted November 8 More details of Sierra's activities, including an in-house mission control: https://spacenews.com/sierra-space-expands-spaceplane-fleet-with-in-house-mission-control/ Here's the sweet part for a tech-head like me, though: Spoiler That is the demonstrator version of their smallest habitat, with, if you zoom in, models of the possible 4-module station, stowed configuration inside the fairing, inflated configuration and the development paths and stowed configuration of the larger LIFE modules. If I don't miss my guess, the display we can partially see on the lower left has it standing on the Moon. A hab is a hab, it seems. Very exciting.

I really wanted to see that in the news release, maybe next time Quote Link to comment Share on other sites More sharing options...

Though the heating during compaction probably does a good job of that. And yes, I’m aware that there are some very tiny things that survive vacuum reliably well Edited Sunday at 07:08 PM by darthgently Quote Link to comment Share on other sites More sharing options...
