I found some footage of the tripropellant preburner demonstrator hot fire test from the Aerojet-CADB (KBKhA) RD-0120 program. The article also includes this video as well.

I like chaos in my programs. At least a little. The permutations allow for new structures to form. This new budget is maybe too much chaos though. nasawatch.com/trumpspace/c...

2 sides of the coin ay. We caught it for a second time; Yay. But we lost it for a second time for a same failure mode; Nay. It's so weird having the two extremes of SpaceX right next to each other. It's annoying because we were set for 2025 and now this has to be dealt with.

Honestly if I disagree with you, it probably means I at least have hope for you. A certain group of people are now pointing lasers at commercial aircraft which they think are drones, I'm never going to interact with them. It's pointless. You however, can grow. And maybe I can to.

Conjunction vs Opposition is everyone's favourite argument, even though it will be decided for us. I guess I just think that the view that minimizing time spent at Mars/on mission as a FOM is bad and results in priotizing/funding delta V over mission duration capabilities.

Updated Nova page. Dropped a couple secs of ISP on that second stage to allow for flat heat shield, probably for cooling (and maybe hot staging) reasons. Stretched, to be expected, as thrust is pushed, expect tall rocket with hydrolox second stage activity.

Varda's success in any measure is one of the companies I care about most. It's the leading effort to crack open the new market of space pharma (maybe very big); if hypersonics is how the sausage is made I guess that is also cool. spacenews.com/u-s-air-forc...

"Now if only we could talk them into getting a real landing system to go with that stage..." quote from Jon Goff in October 2006 about SpaceX Falcon 9. At the time SpaceX were pursuing passive parachute recovery, which is nowhere near as effective as VTVL reuse for RRR.

Hmm. This is a very interesting platform. Twitter being owned by Elon incentives the stans to stay there, so we get to see what space looks like without them. Lots of very 'interesting' posts about SpaceX or at least in how they were derived. Am I in a fighting mood?
