The Soviet Union launches Venera 3, its third attempt to send a spacecraft to Venus. Intended to land on the surface of what is still thought of as a near-twin of Earth, Venera 3’s landing capsule does indeed enter the Venusian atmosphere in March 1966, though the capsule loses contact with Earth and goes silent before ever hitting the surface of Venus. Venera 3 may be the first human-made object ever to arrive on another planet, but no telemetry exists to prove that it arrived in one piece.

Soviet engineers and space scientists come achingly close to succeeding in landing a robotic lunar lander on the moon’s surface. Luna 8, the latest in a long line of problem-plagued would-be moon explorers, lifts off. A new, improved version of the nearly 3,500-pound spacecraft, Luna 8 manages to last longer than the previous three attempts at Luna landers, but loses control mere minutes from a safe touchdown, crashing into the moon instead. The Soviet Union will finally achieve a safe landing on the moon just two months later with Luna 9.
Gemini 7 is launched with Frank Borman and Jim Lovell aboard, on a grueling two-week endurance mission which also sees the first manned space rendezvous. The 14-day flight sets a new space endurance record that stands for five years – none of the lunar landing missions will last that long – and the astronauts function well throughout the flight, though some of Gemini 7’s systems begin to fray at the edges toward the end of the mission. Eleven days into Gemini 7’s flight, Gemini 6 is launched on a one-day mission to act as the rendezvous target, and the two manned vehicles close to within mere feet of each other – a first for human spaceflight.
