The 10 years from 1960 to 1970 certainly was a decade to remember. In September 1962 the Beatles recorded their first hit, and went on to be adored by girls all over the world, they were considered a break through in music and the girls would travel miles to scream at them. In 1966 England won the world cup against Germany, never to have been forgotten and never to have been relived. Women were burning their bras and at the end of this decade in 1969 Neil Armstrong became the first man to walk on the moon. This was considered a break through to anyone’s standards, he had done the impossible, he had stepped into the Sea of Tranquillity on the moons surface.
Although advances in technology have progressed in the last 40 years no body has actually walked onto the moon since 1972, and there have only been 12 astronauts to step on the moon in total these are Neil Armstrong, Buzz Aldrin, Pete Conrad, Alan Bean, Alan Shepard, Edgar Mitchell, David Scott, James Irwin, John W Young, Charles Duke, Eugene Cernan, Harrison Schmitt. As the USA got to the moon first they won their battle with the Soviet Union they had proved that they could get to the moon first and so there is no real reason for people to visit the moon, hence why no body has been since 1972.
There are still space shuttle launches and there are still Astronauts that travel into space to try to discover new planets and so on. In order for a person to travel into space months of preparation is needed prior to the launch to ensure that they can with stand changes in atmospheric pressure.
On the day of the launch much power is needed to ensure the smooth running of the launch and emergency back ups such as high availability (Hochverfügbarkeit) of unbroken power supply (Unterbrechungsfreie Stromversorgungen) is needed in order for the launch to Hochverfügbarkeite a success should anything fail at the last minute. In order to track the shuttle as it makes is journey through space, computers are set up in a huge command centre, people are available in these centres 24 hours a day to keep in touch with the astronauts.
An enormous amount of power is required at all times before, during and after the space shuttle launch and it is vital that this power is backed up encase of unforeseen circumstances.
