  • A few of my favorite shots from my time spent at Kennedy. It's impossible to express how amazing it is to experience a launch up close. Most of these are STS-115.

    It's what I used to do... Getting two vehicles moving that fast to be together at the same place at essentially 0.1 fps difference in velocity is a true orbital ballet.

If that’s SN10 adjacent to 9, I hope it survived 9’s landing ok. 

Seems a bit wild to try to land that shit right next to the other.

My FIL sold a shitload of ultra-high-grade polished stainless steel sheets to an outfit "down near Boca Chica" a while back... I'd bet dollars to doughnuts they're getting made into starships

10 is basically just the shell of a silo right now.   Before the launch, one of the analysts remarked SpaceX was not worried about damaging it in its current state.

Question I do not know the answer to:

On the crash/landing strategy - if this thing can hover at 30,000, why is the flip from horizontal to vertical so late in the process (a few seconds prior to touchdown) when there is not time to correct any errors?

My guess is fuel capacity. I didn’t stay at a Holiday Inn son I could be way off.

Likely has something to do with the additional fuel that would be required to maintain a stable decent once back in upright position.

They actually prefer it to say horizontal as long as possible because the greater surface area slows it down faster, but yeah, they probably want to work on the landing

SpaceX blew up quite a few falcon 9's trying to land them, and starship is integrating a brand new engine design. I'd bet they figure out the landings before too long lol. 

The belly flop maneuver is pretty profound for descent though, they can fall at a terminal velocity of around 80-100 MPH. That saves them a huge amount of fuel for the return and will increase their payload capacity. It'll be a hell of a show while they figure it out, too lol

Interesting simulation about flip altitude

Awesome link. Thank you.

Meh, would have been better set to Ode to Joy.

Agree, but I like the Halo tie in (since daddy musk is taking us to mars).

Ignition then abort.  Abort was 0.1 secs from release.  Determining whether they will try again today (doubt).

Launch window closes at 6 Texas time.

Tri-Vent - ~10 minutes to launch. 

(great job readying the ship so quickly. Every step is an opportunity to learn).

It's pretty remarkable the rate they're producing not only new rocket bodies and tanks, but the engines to go on these things. They're gathering so much data and making so many little improvements each flight. It's really cool to see in real-time. If all goes well, I'm looking forward to watching some Scott Manley and other youtubers analyzing the flight tomorrow

Super interested to see if their new strategy for landing works out. Previously they were only lighting 2 engines, so when one had a hiccup it would kill the landing attempt. Now they're gonna light all 3 and pick the best 2 to land with. 

It's fucking AWESOME to see the thrust vectoring at work, just look at that gimbaling!

FLIP AND BURN IS GOOD!

AND SHE STICKS THE LANDING!!!!! Leaning a little bit, and it's slightly on fire, BUT IT LANDED!

It looks like the legs didn't fully deploy, or they failed. But this is a huge step forward
