Rocket To reach space we want to use rocket Most of the rocket is filled with liquid fuel and a liquid oxidizing agent. The fuel and oxidizing agent mix and ignite in the combustion chamber; the presence of the oxidizing agent ensures that the fuel burns far more efficiently than it could if it depended on the surrounding air for oxygen.

Spacewalker with Manned Manoeuvring Unit Astronaut Bruce McCandless floats freely above the earth, wearing a manned manoeuvring unit (MMU) during a shuttle mission. McCandless helped design the MMU and was the first to fly one. The MMU is propelled by small nitrogen thrusters controlled by the astronaut’s hands. Because no umbilical cord attaches the astronaut to the spacecraft, the MMU gives much greater mobility than was available to earlier spacewalkers.

Working in Free Hall Astronaut Robert Cabana, pilot of Shuttle Mission STS-41, prepares to use a specialized camera on the mid-deck of the shuttle Discovery. The camera is just one of many pieces of equipment carried on every shuttle flight to record all aspects of the mission. Though the astronauts and their equipment float freely when the rocket motors are turned off, they are being held in orbit by a gravitational force that is almost as intense as it is on the ground.

Playing in space The weightlessness of space makes it possible to move about with ease. On that picture astronauts aboard the space shuttle Discovery play in the shuttle’s mid-deck. Astronaut David Hilmers (left) uses his arms and legs to propel himself after astronaut George Nelson (right) and astronaut John Lounge (bottom).

Sputnik 1 aThe Russian Sputnik 1, launched on October 4, 1957, was the first artificial satellite put into orbit around the earth. This historic launch began an era of intensive space programmes by both the Soviet Union and the United States, a surge of interest sometimes called the “space race”. In the next three decades, hundreds of probes, satellites, and other missions were to follow Sputnik on the quest to explore both the wonders and the practical potential of space.

On The Moon On July 20, 1969, American astronaut Edwin “Buzz” Aldrin, Jr. (pictured) became the second person to walk on the moon. Aldrin stepped onto the moon shortly after fellow Apollo 11 astronaut, Neil Armstrong. While millions of people on earth watched a televised broadcast of the event, Armstrong and Aldrin spent two hours exploring the lunar surface, gathering samples, taking photos, and setting up experiments. Armstrong captured the exultant mood in this brief speech broadcast from space.
