Luna 2

In 1959, Luna 2 was launched, one of a series of unmanned Soviet lunar probes, and 36 hours later on 14 Sep 1959 would become the first spacecraft to strike the Moon. It was followed by Luna 3, launched the following month, on 4 Oct 1959, which made the first circumnavigation of the Moon and returned the first photographs of its far side. Earlier, the Luna 1 mission had blasted off 2 Jan 1959. That spacecraft failed to impact the Moon as intended, due to a guidance system failure, but it became the first manmade object in solar orbit.
