A free flight experiment is conducted at a comparatively lower atmospheric pressure by means of a piston-driven range. The preliminary measurements are made concerning the density pattern around a sphere flying with the speed of about 2km/sec through the atmosphere of 0.01~0.05 Torr in pressure. The density distributions along several lines parallel to the flight path are measured by means of electron-beam fluorescence technique. The results show that the density monotonuosly decreases from the point behind the bow shock wave toward downstream, and that there appear no appreciable disturbances like compression waves emanated by the wake.
