The launch was really neat to watch! At the risk of sounding like a moon landing hoaxer, did anyone else scratch their head and raise an eyebrow when the reusable rocket landed on the ship? No rocket, loss of video connection, then voila! a rocket. There was no smoke or anything that looked like it just landed. Idk, maybe my tin hat slid down over my eyes a little too far to see correctly

Here ya go Philip: smoke and everything. It boggles my mind! https://www.youtube.com/watch?v=Dm__ZSLc6IsEdit: some are saying this was an earlier one, not from 5-30-20

The problem with the Drone Ship is that the vibration from the rocket wrecks the satellite link, so it always cuts out.

Oh, hell, that was absolutely astounding!!

Username Protected wrote: Man I love that they are pushing the envelope. The live stream was awesome. Was surprised how much the fins were flexing as well as they way they can fold. The ‘flip’ was a pretty rapid maneuver. Looked like they did it mostly with thrusters. I already raved about this event on the thread in Plane Talk, but I have to do it again... This was a magnificent flight with many firsts and so much success. SpaceX is doing things with a rocket that have never been imagined outside of science fiction, and they're doing them incredibly well. This was a HUGE success. The fins weren't actually flexing, they are actively articulated to control the spacecraft's orientation during free fall. Folding is part of that function. During the "flip", the bottom fins fold in to reduce air drag, which lets the aft end of the vehicle fall faster than the nose. At the same time, the propulsive motors fire and articulate to drive the rotation and then continue to do so to control the now vertical Starship's orientation and descent. The flight was just spectacular to watch. Liftoff and flight to 12.5 km, sequentially powering down Raptor motors to arrive at apogee essentially in a hover, then translate laterally to position for the fall-over maneuver. Remaining Raptor off, thrusters and fins to establish initial orientation, fin articulation to control the attitude and glide path of the descent (they flew from over the ocean to overhead the landing site), then at about 3000 AGL, two Raptors on, Aft fins tucked, rotate to vertical and land on the pad. Unbelieveable. The failure to land gently was the result of a fueling issue. Everything else appeared to work perfectly. The problem as tweeted by Elon was insufficient pressure in the fuel header tank that fed the motors. This essentially starved them, causing one of the pair to flame out. The other did its best but couldn't do the job alone. The green flame is indicative of what's being referred to as "engine-rich exhaust", meaning that the rocket motor was melting and pouring itself (in this case copper) into the exhaust stream, coloring the flame. The cause of the loss of pressure in the fuel system will be the subject of a lot of scrutiny I'm sure, but the reports are that the rocket motors performed flawlessly, and so did the rest of the vehicle. That being the case, this looks like a huge success with only one substantial issue to resolve before the next flight. SN9 is sitting in the high-bay right now, ready to go. It won't be long before we get to see the next history making flight. Go SpaceX!
