🚨 THIS IS A FALCON 9 LANDING TEST - IN A LIVING ROOM. What you're watching is a custom EDF rocket. No propellant - a 90mm ducted fan inside a duct pushes mass downward, same physics as a rocket engine, just electric. 70mm fan on 7S makes 8kg+ thrust - thrust > weight = hover. Uses thrust-vectoring + PID like a real lunar lander. DIY VTVL for $250. 🛸🚀

ありがたいことに多くの評価をいただいたので、英語モードをくわえました。またJ2摂動の影響も加えています。楽しんでください! Thanks, everyone, for trying out the orbital viewer! I've added an English mode and J2 perturbation effects. Hope you enjoy it!
Opus 5.5 を使って軌道6要素をインタラクティブに学べるツールを作った。教科書などを読んでも絵が平面的でイメージをつかむのに苦戦していたけど、マウスでグリグリ回して色んな角度で3次元的に理解できるのに感動。良い時代になったもんだ。 ki-math.github.io/orbital-el…

Accurate analysis
I find it funny that some people got hung up on Starship not having gone orbital before Flight 14 when in the grand scheme of things it was completely arbitrary in terms of performance. The 19ish second burn only added about 91 m/s of velocity (a 1.2% increase in velocity) This capability has been physically capable since Flight 6 which demonstrated a single Raptor relight in space. Heck, Flight 13’s burn was about 14 seconds, but intentionally oriented to primarily do a plane change instead of a prograde insertion burn for continued safety. Any of the relights COULD have done the orbital insertion burn, the duration was not of any special technical capability. The reason Starship didn’t go orbital until Flight 14 is probably what we should applaud them for the most… SAFETY. Their methodical approach to getting good data and going one step at a time while hucking the single most massive object ever put into space proves they weren’t just doing things haphazardly, despite the occasional narrative from the outside. While it’s easy to compare Starship to vehicles like SLS or Vulcan or New Glenn, the reality is the focus hasn’t been on orbit, it’s been all on the “downhill” side of that. Safe and targeted de-orbit, clean reentry, targeted and soft splashdown. That’s the part that has (almost) never been done before. And here I do have to add a little Space Shuttle admiration for figuring out a lot of these things on its first flight in 1981 (although it came a bit close to not being successful). Pretty amazing there was a vehicle of similar scale capable of such precise deorbit and reentry that it landed on a runway with no go-around capabilities. Crazy. But Starship is well on a path to absolutely leap-frog the Space Shuttle in terms of performance (already over double and someday 6 fold) and hopefully in terms of full and rapid reuse. I hope we see the latter part speed up even more now that orbit has been demonstrated. Exciting times ahead!!! Keep going @spacex @elonmusk
