Radio Astronomy Explorer (RAE)

The Radio Astronomy Explorer investigated low frequency (long wave-length) radio emissions from the sun and its planets as well as galactic and extragalactic sources. The spacecraft had a mass of about 190 kg. It was equipped with a dipole antenna (36 m from tip to tip) and two V-shaped antennas. These antennas consist of four 230 m long elements which form a large "X" with the spacecraft in the center. The V-shaped antennas provided gravity gradient stabilization. The RAE program, as planned, called for a series of four spacecraft with the first scheduled for launch in early 1968. Two missions (RAE-A and B) were approved and payloads for them were selected. Missions RAE-C, and D were not approved. RAE-A and B were intended for a circular orbit with an altitude of 5800 km. Inclination of the orbit to the equator was 58 degrees retrograde and the orbital period was 3.83 hours. (en)
