Luna 10 was launched on 31 March 1966 and Luna
12 on 22 October 1966. They were the first Luna
spacecraft intended to go into orbit around the
moon, rather than soft or hard landing there. On 3
April 1966, Luna 10 was put into a selenocentric
orbit -- becoming the moon's first man-made
satellite. It had an apogee of 1015 km, a perigee of
350 km, an inclination to the equatorial plane of 72
degrees. The orbital time was 2 hours 58 minutes.
The Luna 12 orbit was: apogee 1740 km, perigee
100 km, inclination 20 degrees, orbital time 3 hours
25 minutes. Both missions carried instrumentation
to study the Moon and cislunar space.
The instruments comprised a multichannel
scintillation gamma-ray spectrometer intended to
measure the moon's gamma- radiation. However,
the Luna 10 and 12 spacecraft both measured the
cosmic gamma-ray background during their flight to
the moon. >more
