Brotoro Posted March 15, 2023 Share Posted March 15, 2023 Tee Eee *giggle* Liftoff. MECO. Good 2nd stage ignition. Hmm. Partial boostback. Interesting. Quote Link to comment Share on other sites More sharing options...

Minmus Taster Posted March 15, 2023 Share Posted March 15, 2023 Bullseye! It was so precise that I thought it had missed up until it was right over the barge. Quote Link to comment Share on other sites More sharing options...

AckSed Posted March 15, 2023 Share Posted March 15, 2023 Fascinating experiment launched in Crew Dragon: https://www.nrl.navy.mil/Media/News/Article/3328656/nrl-to-launch-first-in-space-laser-power-beaming-experiment/ It'll be beaming it down to the ground, but this is the first step towards making "an extension cable long enough".

darthgently Posted March 15, 2023 Share Posted March 15, 2023 Again I'm wondering about the green flame coming from MVAC. Not a big deal as it is expendable, but it does look like they are intentionally pushing it. But my limited knowledge is that the green would only appear if the copper in the iconel were burning off and that may be a bad assumption. Maybe my screen colors are off Quote Link to comment Share on other sites More sharing options...
Krakotte Posted March 15, 2023 Share Posted March 15, 2023 It's probably the TEA-TEB used to start the Mvac. Quote Link to comment Share on other sites More sharing options...

Maybe my screen colors are off The Mvac expansion nozzle is Niobium alloy, and an Nb flame test is green/blue, so perhaps it's from that?

At ignition it’s TEA-TEB. Quote Link to comment Share on other sites More sharing options...

I looked at the replay of yesterday's launch above, and there is maybe a green tinge to the whole burn? hard to tell without some color checking on the camera Quote Link to comment Share on other sites More sharing options...

Could be camera, intermediate processing, or some monitors, or real If it is real, and having characterized how long the engine can be reliable under those conditions they decided just to roll with it on an expended stage, then good play in my view. If it ain't broke enough, no hurry to fix. Use up all the current stock first Edited March 15, 2023 by darthgently Quote Link to comment Share on other sites More sharing options...

And yet, the milestones are met. Eventually. And even late, are still impressive. Whodathunk the number of successful F9 landings would be at the current number at this point back when protos were going RUD? Who would have predicted the huge workhorses cargo and crew Dragon would become back when it was covering a test pad with unplanned inflagration? Or OneWeb launching on F9? Or Tesla manufacturing and sales completely obliterating even modest negative predictions back when the first batch rolled out? Boca Chica at its current rate of progress blows my mind. While Musk's timeline predictions are a crazy joke, I have to wonder about the method to the madness. He clearly knows more than I on how to motivate his teams. Maybe it is as simple as short circuiting procrastination by making the goal ridiculously soon Edited March 17, 2023 by darthgently Quote Link to comment Share on other sites More sharing options...
