Spaceception Posted August 17 Share Posted August 17 I'll be honest, I like this a lot better than Blue Origin as a buyer. Blue has a rocket, Sierra doesn't, and Blue is more incentivised to use ULA's technology and contracts to improve and build on New Glenn instead of keeping up with two production lines. Vulcan has a future (however tenuous) if Sierra buys them, it doesn't if Blue does. I also think it holds certain advantages and an appeal to Sierra if they had their own launch vehicle, since they're going into space stations, cargo/crew access and satellite production, which benefits greatly from only having to pay internal costs, instead of purchasing externally.

I think all the astronauts that have puked from sea sickness after splashdown would welcome a runway landing in Dreamchaser. I realize the money likely isn't there from NASA at this point in time to shove it through crew rating after Starliner and Dragon funding, but it sure would be nice. We still need a second crew option. The wrong horse got picked in my view Edited August 17 by darthgently Quote Link to comment Share on other sites More sharing options...

Like Neil deGrasse Tyson once said: If an alien were to land on Earth in a capsule he'd be like "meh..." It's just not cool. Dreamchaser landing on a runway is a significant step in the right direction. Starship too. Capsules? Lame. Quote Link to comment Share on other sites More sharing options...

GuessingEveryDay Posted August 17 Share Posted August 17 According to this neat document from 2014 about Dream Chaser, it said that it can land on any runway that's longer than 8,000 feet. https://www.icao.int/Meetings/SPACE2015/Presentations/5 - C. Lee - Sierra Nevada Corp.pdf Darn, the closest airport to me only have runways that are 4,158 and 7,505 feet long... Quote Link to comment Share on other sites More sharing options...

Financially I can't see it happening easily, but the ULA sale and Sierra's interest made me wonder about it as they are clearly wanting to secure a launch vehicle. It could launch with SpaceX with some engineering but a second launch option seems to indicate Sierra wants a fully separate and redundant system. Like maybe they think it is still possible to get that NASA crew backup slot Quote Link to comment Share on other sites More sharing options...

Better arguments are Dreamchaser allows for a lot more options on entry, doesn't involve a lengthy ocean retrieval foray, saltwater mitigation, or subjecting astronauts to a return to 1G swirled with bobbing and pitching on ocean swells for an hour or more in their favorite suit Quote Link to comment Share on other sites More sharing options...

If they have the leverage/cash how could they not make an offer. They may see it as the only serious option Edit: Found this good rundown on current situation with Sierra and ULA Edited August 17 by darthgently Quote Link to comment Share on other sites More sharing options...

Wow that Sierra Space might actually buy ULA. It's a bold strategy. Let's see if it pays off for 'em. Quote Link to comment Share on other sites More sharing options...

AckSed Posted October 4 Share Posted October 4 (edited) https://arstechnica.com/space/2024/10/ulas-second-vulcan-launch-will-pave-the-way-for-military-certification/ tl;dr ACES or something like it is still of interest to Tory Bruno. They are still developing it and Integrated Vehicular Fluids (the plan for autogenous pressurisation, RCS propellant and power for pumps from recirculated gasses via a small piston combustion engine) though there's no real money behind it (I think). If they do extend the on-orbit lifespan, that extends the variety of missions. Perhaps even propellant depots (maybe for that nuclear-thermal rocket DARPA's touting). Of relevance to the flight is they're looking to try some things out with the Centaur upper stage to reduce boil-off and extend its lifetime in orbit.
