Well, that'd do it. It'll be interesting to see how they work around that one.

On a different note, SpaceX is going for a doubleheader on Saturday. Morning launch from Vandenburg and evening launch from Florida.

Yeah, brings the whole landing and launching on natural services issue back to light. The lunar version of Starship has side mounted engines lunar landing/launch engines, but that won't work on Mars.

Thanks for the reminder! Always forget to convert from UTC until close to the date.

Oh. Well, that's "good" but maybe time for a flame trench?

They want to design around flame trenches since they won't have the option on Mars.

Right, but there won't be concrete covered with epoxy on Mars either (at least not right away).

What are the landing pads at the Cape made of? The drone ships have steel decks?

Based on their history of melting launch towers, pads, and GSE I'm guessing they are still learning about the power of Raptor to destroy things. :)

At the Cape they have flame diverters and shock dampening water systems. They've already started a new launch tower at Boca Chica, but the cement has been curing for a couple months now. I'm guessing they planned to move to it after SN8 testing, at minimum for SH-SN1.

I would imagine landing isn't the problem as much as takeoff.

This is cool. Looks like passenger (or lunar considering recent paint job?) Starship is getting an interior mockup maybe? Capsule hotel style berths it appears.

If anyone's interested, RocketLab is trying out their new version tonight. The booster now has parachutes on the first stage, and they will be recovering it after splashdown. Eventually the plan is to snag it with a helicopter. They're donating a dollar per viewer to the Starship Children's Fund, so at least give it a click if you see this.

Thanks, that was a fun watch. Not as slick as SpaceX but still great to see more private space flights going on!

No space junk left behind. That's impressive...

Launch coming up in around 45 minutes

Duh

Pretty cool mission this time. This satellite will yield some pretty cool science.
