SOXBLOX Posted June 13, 2021 Share Posted June 13, 2021 I'm figuring this is a prototype for the upcoming hypersonic weapons tracking megaconstellation. The MDA has been studying this for a while now. The only alternative is "to wallpaper the Earth with radars", so it's a pretty good deal. https://spacenews.com/u-s-would-need-a-mega-constellation-to-counter-chinas-hypersonic-weapons/ Quote Link to comment Share on other sites More sharing options...

tater Posted June 15, 2021 Author Share Posted June 15, 2021 Launch in a little over 8 min Real video: Looks like a scrub possible, they are having some issues they are working... Might have reset whatever system was throwing the bad telemetry? Green now. Such a tiny thing. Quote Link to comment Share on other sites More sharing options...
SOXBLOX Posted June 15, 2021 Share Posted June 15, 2021 Here's a piece on the USSF Pegasus launch. Well, here... It took less than four months to design, test, and integrate this payload, which is nicknamed Odyssey. Still no details on the mission. They're CLASSIFIED.

bigboibru Posted August 2, 2021 Share Posted August 2, 2021 Does anyone know what this thing is that tears off the lower stages of the Minotaur I straight after launch. I think it has something to do with the Minuteman II booster, but I'm not really sure. Reference Image: Quote Link to comment Share on other sites More sharing options...

The Minuteman missile was housed in solos that were underground (cool), and air conditioned. Wasn't designed to sit out on a pad in the sunlight.

But then how come the SRBs used on the Shuttle and SLS Block 1/1B, which also use APCP as a propellant, don't need insulation? Is it because they also use PBAN (polybutadiene acrylonitrile) as a propellant? Or is the insulation just put inside the booster instead, rather than tearing off at launch. I suppose this would've made sense for the Space Shuttle, as since the boosters were recovered there wouldn't be a need to get new insulation for every launch.

I suppose this would've made sense for the Space Shuttle, as since the boosters were recovered there wouldn't be a need to get new insulation for every launch. I'm unsure. Shuttle had SSMEs to pick up any variability in thrust due to temperature regimes I suppose, so it might just be a margin thing. Shuttle had decent margin for variability (and throttleable engines), and perhaps Minotaur I is much tighter margin wise due to not really being designed as a launch vehicle.

RyanRising Posted August 11, 2021 Share Posted August 11, 2021 Pretty smooth. As always, I wish we had rocket cams, but the telemetry's a decent substitute - no shortage of info there. And, of course, it's always nice to see these things go off without a hitch. Quote Link to comment Share on other sites More sharing options...

Yeah, rocket cam is always a win. Watching a vehicle gain orbit in real time is incredibly cool. Quote Link to comment Share on other sites More sharing options...

Option 2 would be a low-orbit, decentralized SBIRS - and would have very little to actually do with hypersonics, since it would target ballistic missiles in the boost phase, where having an HGV or a conventional conical RV makes no difference. Thing is, Option 2 has nothing to do with space domain awareness, which explicitly concerns orbital targets. It sounds like Odyssey could be similar to Canada's Sapphire.
