Maintenance of Hubble Space Telescope

Nasa director Mike Griffin said he would send the shuttle with Hubble telescope maintenance crew lying in orbit near the earth. Since being launched into the air Hubble has sent many precious images but if not maintained, it will soon be damaged.

Dr. Griffin told Nasa staff that with the current shuttle launch system, he thought that sending Hubble maintenance astronauts could now be done without risk. This mission will use Space Shuttle Discovery and may be carried out in 2008.

Without maintenance, Hubble will be out of operation for about two or three years. Hubble's chargers and hoists are degraded, needing to be replaced. Astronauts will also install two new devices, the Wide Field Camera 3 (WFC3), and the Cosmic Origins Spectrograph (COS) recorder. These new tools will improve Hubble's vision and vision.

Not dangerous

Maintenance will extend Hubble's life to at least 2013, and at that time Nasa will be able to be ready to launch the James Webb telescope instead. Dr. Griffin's decision contradicts the opinion of his predecessor, Sean O'Keefe, who canceled a similar mission after the 2003 shuttle shuttle disaster in 2003.

The insulation of Columbia's ship was damaged during the launch and the ship was destroyed when returning to the atmosphere 16 days later. Mr. O'Keefe has decided to adopt a safety policy, stating that damaged ships will have to park at the Space Station until the ship is rescued.

Since then no train has been launched to repair the Hubble glass because shuttles often do not contain enough fuel to orbit the observatory and space station's orbit. Now with Mr. Griffin's decision, NASA needs to prepare a new policy to prevent the shuttle from getting damaged by its orbit.
