The corridor and trajectories of space vehicles during reentry flight using negative lift are studied. Numerical results are obtained for the corridors and trajectories using negative and positive lift, respectively. The following conclusions are obtained: in the case of a larger lift-drag ratio, the first one-third reentry corridor using negative lift is wider than that using positive lift; the total mass cost (TMC) by negative lift is smaller than that for positive lift, where TMC is the total mass of fuel consumed for the vehicle to deorbit from the mission orbit and the mass of the thermal protection system of the vehicle, in the case of a smaller lift-drag ratio. The two kinds of reentry trajectories produced by positive lift and negative lift are approximately the same. Therefore, the concept of return flight using negative lift is superior to that using positive lift.
