You're right. I was thinking of the Atlas, which had to have the tanks pressurized if not full of fuel to prevent collapse from its own weight.

Can it do a vnav descent with a tailwind?

Maybe a little better than some of -800 I've flown. 85 kt tailwind and had to pop the boards out for a moment to cross polar.

Perhaps this satellite isn't heavy enough to require the extra performance, and they already have infrastructure in place at the Cape. If they moved the same rocket to Kourou it would still have to be fully fueled, for structural reasons, so they'd just schedule a shorter burn.

Lots of extra fuel on the Falcon 9, enough -in fact- to do this after launching a payload to orbit:



(Grasshopper is the Falcon 9 first stage, this is obviously a landing test. The last Falcon 9 first stage did perform the powered return test over water...)

VNAV and ATS work mucho better. Its even harder to slow down than the -800 though.

So now the company is asking 320 CAs to liquidate their vacations because they're short. Good thing they didn't backfill those positions. :rolleyes:

Space X is cool. I was surprised when I read the amount of land they leased for this test ... 1/2 acre. Guess they were confident.
