On November 3, NASA said that the Hubble Space Telescope operating in earth orbit failed, leading to the safe mode of scientific instruments. At present, NASA staff are still studying how to solve the problem < p > according to a brief statement previously issued by NASA, the scientific instruments carried by the Hubble Space Telescope entered safe mode on October 25. In a longer statement released on November 2, NASA revealed more details about the failure of the Hubble Space Telescope. The agency is identifying the specific causes and working to restore the telescope to normal < p > NASA staff said in a complete statement: "NASA is continuing to investigate why the Hubble Space Telescope equipment has recently entered safe mode and suspended operation." "the instruments are normal, but will remain in safe mode during the mission team's investigation." < / P > < p > according to the latest statement, the instrument stopped working at 2:38 a.m. Eastern time on October 25. But NASA also revealed that a similar fault occurred two days ago, but it was soon solved < p > "the scientific instrument of the Hubble Space Telescope sent an error code at 1:46 a.m. EDT on October 23, indicating that a synchronization information was lost," NASA said. "Relevant synchronization information is the time information used by the scientific instrument to correctly respond to data requests and commands. The task team restarted the scientific instrument and the telescope returned to normal the next morning." < / P > < p > NASA statement pointed out that when the problem reappears, the error code indicates that "synchronization information has been lost for many times", and the scientific instrument automatically enters the safe mode according to the program < p > according to the statement, at present, staff are remotely analyzing spacecraft data and developing procedures to obtain more data for research. But the work will take at least a week to complete The Hubble Space Telescope was launched in April 1990, and numerous problems have occurred since its operation. The Hubble Space Telescope was designed to allow NASA astronauts to repair and upgrade it on the space shuttle. The last time astronauts performed such a mission was in 2009. Since then, NASA staff have been maintaining the Hubble Space Telescope remotely on the ground < p > the current problem of the Hubble Space telescope does not seem to be as serious as the computer failure this summer. That failure affected the operation of the whole telescope, which was down for more than a month. The team was forced to switch the Hubble Space Telescope to backup hardware to resume normal operation. (Chen Chen) < / P > < p >
