That was awesome, I only really got to half see it since boss was asking questions about work related stuff but I did get to see the two boosters land in sync, that was incredible.
Also, is it going to Mars or not? My understanding is that it's heading into a Mars sphere of influence, except they won't be doing an insertion burn so it won't actually stay there, and just end up around the sun. Is that right?
It would be kind of cool if they did do an insertion burn but at the speed it will be passing Mars at I imagine they'd need like an extra booster worth of fuel for that at least. Technically more, because now you need more fuel to lift that booster, and need more fuel for that fuel... Space is hard.
I have a feeling they will come up with a version with 4 boosters though. Could add 2 more on the other sides. Then add more boosters to the boosters and now you go full Kerbal.
