Abstract
Technology is described for enabling a reusable launch vehicle to compensate for wind prior to engaging propulsion during approach to landing. The technology can cause the reusable launch vehicle to begin un-powered descent; determine a first rotation angle of the reusable launch vehicle about a specified vertical descent path, the first rotation angle corresponding to a first attitude of the reusable launch vehicle selected to stabilize the reusable launch vehicle on the vertical descent path based on a wind speed and angle; and prior to engaging a propulsion device, command a second rotation angle for the reusable launch vehicle, the second rotation angle corresponding to a second attitude that, when the propulsion device is engaged, will cause the reusable launch vehicle to remain at least approximately at the vertical descent path.
