Whatever the mission‚ be it manned or unmanned‚ for scientific research‚ applications or space transportation‚ a spacecraft must withstand the extreme stresses which occur during the launch phase‚ and once in orbit‚ the rigours of the space environment. There is one way of making sure of this: to test the spacecraft on Earth under conditions simulating‚ as closely as possible‚ those it will meet during the launch and its orbital life. This can be done with with tests which demonstrate by application

The failed meteorology mission of 1999 was caused by a machine error due to a computer not converting English units to metric units. Scientists didn’t realize the mistake until they tried to send the space craft up into the air. Nobody had checked the work done on the computer‚ they didn’t feel the need

The team-up between NASA and the Chinese National Space Administration (CNSA) emphasizes the author’s belief that humanity is greater than the sum of its parts. Cooperation between international government agencies is extremely difficult. By putting aside their differences‚ NASA and CNSA were able to return

Carbon–carbon is well-suited to structural applications at high temperatures‚ or where thermal shock resistance and/or a low coefficient of thermal expansion is needed.

Many problem skills had to be used and improvised during the movie‚ Apollo 13‚ but the one that amazed me was when Jim and Fred had to manually adjust the ship. I believe this held a significant amount of importance for getting the astronauts home. Everyone knew that to be able to reenter the earth’s atmosphere the ship only had a tiny amount of room for error. When NASA informed the astronauts that they needed to do another burn‚ but they don’t have enough power to start up the ship for the computers

The Hubble Telescope The Hubble Telescope is an orbiting telescope that provides clear images from space. It is a reflecting telescope and gathers light with a mirror 94 inches in diameter. It is named after an American Astronomer‚ Edwin Hubble who made important astronomic discoveries in the 1920’s. Pictures taken by the Hubble Telescope include: stars surrounded by disks‚ galaxies‚ colliding galaxies‚ and evidence that most galaxies have black holes in their centre. The Hubble Telescope is

Apollo 13 was planned as a Type H mission; Apollo 13 was the third mission to land on the moon. The spacecraft lifted off on April 11‚ 1970. The three crew members were Commander James A. Lovell‚ Command Module Pilot John L. Swigert‚ and Lunar Module Pilot Fred W. Haise. Unfortunately‚ two days later the oxygen tank exploded which force them to terminate lunar landing. According to NASA‚ Apollo 13 seem to be the smoothest flight till the first 55 hours and 46 minutes‚ nine minutes after the TV broadcast
