grabbed from above screen...
The checkout crew uses tablets. Looks like a specialized, rugged tablet.

A friend's brother in law caught a video of it over Monroe, NC.

Any word on SN15?
"SpaceX hasn’t yet announced an official launch date, but it’s rumored it might even take place sometime today, April 29 (there’ve been some official road closures in the area). "

Here's the NSF thread for SN15 updates. You gotta analyze recent messages to do some tea-leaf reading such as road closures, FAA TFR's, "notices to residents", etc.


Weather forecast is a large percentage for rain thru the day.

Safe return for Crew-1


OF course it's way down on the news stories list on all the main news channel/sites.

So it's looking like tomorrow, Star Wars day, might also be SN15 launch day.

As for SN 15, might fly Wednesday. But weather sucks.

Thursday, weather sucks.

Friday looks better.

Weekend...weather sucks.

But what do I know...... I never thought they’d fly SS-11 in total dense fog, or NASA would launch Challenger with massive icicles on the pad. :(

Regarding the Falcon-9 launch, wow, that was pretty much a perfect bull’s eye landing within the circles. Do not recall seeing one looking so dead-center like that (the F-9’s onboard camera helps show how centered it is, and that view is not visible after landing on a lot of flights). Always have to keep in mind, the booster is not aiming at the barge. It is aiming at pre-set GPS coordinates, and the ASDS barge’s job is to keep itself centered at those GPS coordinates. For all I know, the ASDS might have been 6 feet west of the coordinates, and the booster might have missed the coordinates by 6 feet to the west. :)

Back to SN-15, some interesting footage of the flaps being tested, mostly in fast motion. Surprised the skin of the flaps is still so wrinkle-buckled looking, while the body no longer is as with SN-1. That does not give me warm fuzzies for TPS tiles staying on for re-entry....they need to fix that.

Looks promising! Could be less than half an hour from now based on the checklist on the side of the video.

No flames > Flames > Splodey

That's my technical analysis. :D I would sure like to have seen that fire out before they turned off the water cannon.

I had to leave before making sure there would be no earth shattering kaboom from those flames (kids getting haircuts). I hope they got the fire out!

Upright for ~30 minutes after landing, fire's out == winning.

A really good discussion of why Starship belly-flops:

This landing looked so much more controlled than any other, including the one when it “landed” on the skirt and later exploded. It seems like the engine relight worked correctly this time. Very cool!

I didn’t like seeing the fire, but I wonder how serious that is. I wonder if this one will fly again. Can’t wait to see what comes next!
