The Soviet Union led the era of space exploration, starting with a series of 'first's: first orbit launch, first man in space and orbit, first images of the far side of the Moon, first probes on the Moon, first Mars and Venus orbiters and probes, ....
First satellite in Earth orbit
Basically just a large metal football with whiskers, for 21 days Sputnik broadcast radio signals, and supplied information about upper atmosphere density and the ionosphere. After three months, it burnt up on re-entering Earth's atmosphere.
Sputnik came as a surprise to the world, and is generally heralded as kick-starting the space age. The Americans in particular were concerned about a space technology gap, and began its space exploration programme with vigour in response.
On 12 April, 1961, the 27-year-old cosmonaut, Yuri Gagarin, became the first person to enter Earth orbit, and to complete an Earth orbit, aboard the Vostok 1 spacecraft.
The first woman in space was cosmonaut Valentina Tereshkova, who entered orbit on 16 June 1963, aboard the Vostok 6 spacecraft.
The first person to walk in space, that is to leave the space capsule in a spacesuit, was Alexei Leonov, from Voskhod 2, on 8 March 1965.
October 7, 1959: the Lunik 3 probe passed to the far side of the Moon, and took photographs which it transmitted to Earth, revealing its features for the first time in history.
Launches: Lunokhod 1: November 10, 1970; Lunokhod 2: 1973 (Proton rockets)
Lunokhod is Russian for 'moonwalker'. As part of a broader Moon unmanned exploration series (Zond and Luna), the Soviets successfully landed two probes on the Moon.
The spacecraft made rocket-controlled soft-landings in the Sea of Rains and on November 17, 1970. The vehicle descended a ramp to move about the surface.
Achievements: first remote-controlled landers on an extra-terrestrial body. Lunokhod 1 travelled 10.5 km, and Lunokhod 2 travelled 42 km. Both vehicles ran scientific analysis experiments, with penetrating probes and sensors, as well as transmitting images and data to Earth.
1960 - 1973. Launched by Molniya rockets, there was a series of unmanned Soviet missions to Mars. These included fly-bys, orbiters, and landers.
One of the missions, Mars 2, launched on 19 May 1971, sent a 1,210 kg lander to the surface of the red planet. It crashlanded unfortunately. The sister mission, Mars 3, was more successful, soft-landing a lander on December 2, 1971, which sent back part of a photograph before losing contact.
The Phobos-Grunt (Russian for 'Phobos soil') 2011 mission to land a probe on the Mars moon, Phobos, and return a sample of the surface soil, failed to leave Earth orbit.

|Phobos 2||1988||Orbiter lost near Phobos||Phobos Lander planned|
|Mars 96||1996||Orbiter, launch failure||Lander planned|
|Fobos-Grunt / Yinghuo-1, CNSA (China)||2011||Combined mission, 2 orbiters, failed to leave Earth orbit|
1961 - 1984: Venera programme. Some early missions failed to leave Earth orbit, but several missions were able to enter orbit or perform fly-bys of the planet, mapping it and collecting and transmitting atmospheric data.
After many failed missions, eight probes of the series successfully landed probes on the surface of Venus. However, the temperature and pressure (457 °C and 89 Earth atmospheres (9.0 MPa)) were so intense that few landers lasted long enough to send useful data or pictures. The longest lasting lander expired after 127 minutes, but managed to test a sample of soil, and transmit colour images to Earth before failing.
Launch: July 1975, Soyuz U rocket
Vehicles: Soyuz /K-TM and Apollo
On July 17, 1975, the Soviet orbiter, Soyuz 19, docked in Earth orbit with an American Apollo orbiter. The air-locks were opened, allowing the crews to mix and conduct PR ceremonies, as well as some scientific experiments.
This mission was a symbolic gesture of the two super-powers, and is generally interpreted as marking the end of the Space Race phase of space exploration.
Meaning 'peace' in Russian, MIR was a low Earth orbit space station from 1986 to 2001, when it was intentionally destroyed by automatic re-entry. As a modular design, it was a fore-runner of the later ISS (International Space Station), and was assembled over a ten-year period.
MIR was occupied for 3,644 consecutive days by humans, with Valeri Polyakov taking up residence for a still standing off-world record of 437 days in 1994-5. It was designed to house 3 crew at a time.
The station was a microgravity research laboratory. Fields of research included biology, human physiology, geophysics, physics and space technology.

Ernst Ulrich von Weizsäcker, b. 1939, is a prominent German scientist and politician. He is a popular author, with best-selling books like 'Factor Four', the update to the Club of Rome 'Limits to Growth', which explains how a sustainable economy requires reductions in consumption and increases in efficiency of this order of magnitude.
