In
April Yuri Gagarin becomes the first man to orbit Earth, and is in space
for 108 minutes.
Less
than a month later the first American, Alan Shepard, makes a short sub-orbital
flight into space, returning immediately to Earth.
Russia
starts development of the Proton launcher, which remains in use today.
An
Atlas rocket launches the first American into orbit.

first manned Gemini flight.
A Titan
II rocket powers Virgil Grissom and John Young into space to make three
orbits of the earth - the first of a long series of flights which paved
the way for the Apollo Moon programme.
The
Soviets assemble the first N1 rocket using
NK-15 engines.
The
rocket uses 30 of the radical and highly efficient NK15 engines designed
by the Kuznetsov Design Bureau. The NK15
was the first successful closed-cycle rocket engine, developing an extra
25 percent lifting power by channelling the exhaust products from the
pre-burner into the combustion chamber to be re-fired.
The
launch of Apollo 7, which orbits the earth for 11 days.
The
first test flight of unmanned N1 rocket, which explodes 40 kilometres
from the launch site. A second unsuccessful launch takes place in July.
Apollo
11 blasts off carrying the first humans to land on the surface of the
Moon.
Apollo
11 lands - Neil Armstrong and Buzz Aldrin become the first men on the
Moon.
A Long
March rocket launches Mao1, Chinas first space satellite.
The
three-stage rocket is 30 metres high and 2 metres in diameter. Its maximum
payload is 300 kilogrammes.
The
third and fourth N1 rockets both explode in mid-air.
The
launch of Pioneer 10, destination Jupiter.
A new
NK33 engine introduced for N1 rocket.
The
NK33 is the most powerful liquid oxygen/kerosene engine ever built.
Compared to the NK15, it has improved reliability, thrust and restart
capability.

also launches a new Weaver Girl 1 rocket.
The
first of Atlas Centaur rockets series of 46 successful missions.
US
rocket scientists are taken to see stored NK33s.
Scientists
from the US company Aerojet are amazed to find a store of over 60 pristine
engines, of a compact design that they had never seen before. What surprised
them most was that the engines used the closed-cycle technology that
had been rejected by American rocket scientists as being too risky.
The
first static test firing in the USA of a Russian-built NK33 engine.
China
enters the space travel arena.
The
latest version of Chinas Long March rocket launches an unmanned
prototype of a re-useable capsule which has been designed to carry humans
