(I discovered this after successfully wrestling the thing into orbit.) There are no additional asymmetries introduced, so I have no idea why that was other than, FNAR, the command capsule's reaction wheels toggled themselves off. 2) This rocket inexplicably decided to become unstable during liftoff and lean towards 270 (it did not do this on prior launches). Two things are different this time: 1) I'm using a nose-mounted basic chute instead of a pair of radial mounted chutes. I've taken this lander to minmus and come back home in a similar, more aggressive fashion. I've flown this mission before, and came in on basically this return trajectory from Mun once before. This is by far not the most aggressive aerobreaking I've ever done. Apo before atmo is 8M or something like that. Peri is 27km, I can bring that up to 32 or so.
It's an aerobreaking maneuver directly from Munar ejection. There is not enough dV left to abort the landing.
