The Dash 2 satellite was a 2.5-m-diameter balloon used to measure air densities at altitudes of approximately 3500 km. The area-to-mass ratio for the spacecraft was 40 sq cm/g. The orbit, originally circular, increased in eccentricity rapidly under the action of solar radiation pressure. Dash 2 reentered the earth's atmosphere on April 12, 1971.
