NASA begins high-stakes repair to Hubble Space Telescope
CNN
NASA engineers are trying to work their magic on the Hubble Space Telescope, which stopped working on June 13 as a result of a problem with the payload computer on board.
After a month of trying, engineers with the space agency were unable to restart the computer -- and its backup -- so the Hubble team will switch to an alternative power unit on Thursday, according to a NASA statement. If successful, it will take several days to completely return the observatory to normal operations, NASA reported. The Hubble Telescope has shaped our understanding of the cosmos for over 30 years. It discovered moons orbiting Pluto, and it proved that almost every galaxy has a supermassive black hole at its heart. It also played a pivotal role in the discovery of dark matter -- a mysterious substance that can't be seen.More Related News
