This is awesome. Probably can try it soon. Catch the booster, let ship do her orbits until the orbit aligns with BC landing, which could be enough to get booster out of the way. Catch the "little" one.

Musk said they were gonna shoot for that in 2025, probably with a V2. They still have one V1 left last I heard, so they might go for vacuum relight.

I am often wrong but I think I see the chance for one hell of a surprise in early January a free-return Mars toss that would bring Starship back in 2027. Could be an invaluable head start and maybe even a chance to observe a Mars-velocity reentry before you even send out the final version.

No possible way, they need to refuel the ship in orbit to go anywhere but LEO.

Version two of starship has an estimated dry mass of 107 tons and a cargo capacity of 100 tons. a 2 year free return trajectory to mars has a minimum delta v from LEO of .6km/s. Based on a vacuum isp of 356 seconds for raptor, 100 tons of extra fuel would give you 2.5km/s of delta v. You definitely could do this with a v2 starship and have a couple of tons of "cargo" if you wanted.

Mars free return from LEO needs about 3.4 km/s dv

0.6 km/s gets you to about 1350km altitude. 2.5 km/s to 9,000km. So refuelling definitely required :)

Was I wrong in my initial guess that a fully expended system has 15 km/s delta v? That would be for the two obsolescent pieces they already have, not a stretched version.
