Technique presented may facilitate employment of atmospheric braking to attain orbit about planet as terminal phase of interplanetary trajectory; proposed system comprises set of small aerodynamic precursor vehicles which will be launched at various angles in planetary approach trajectory plane to acquire atmospheric data needed by mothercraft; data will be telemetered from each precursor, which will contain its own small rocket to allow trajectory change; results of feasibility study show that precursor-atmospheric braking technique could provide Martianorbital payload factors of 4 to 5 compared to straight retropropulsion system.
