NASA's Chandra Observatory is operational again

NASA's Chandra X-Ray Observatory, observing the universe under a high energy light since 1999, is back in action after suffering a glitch from the failure of the gyroscope and to be in safe mode last week.

Chandra's safe mode on October 10 has now been understood and the Operations team has restored the normal operation of the spacecraft, according to the US Space Agency.

"Safe mode was caused by a small problem in one of Chandra's gyroscopes after a 3-second period of bad data that led the computer to calculate an incorrect momentum value. of the spacecraft.The erroneous indication of the momentum then triggered the safe mode, "NASA said in a statement Monday.

The team completed its project of permutation of gyroscopes and storage of the gyroscope which encountered the problem.

Once configured with a series of pre-tested flight software patches, the team will hand Chandra back into scientific operation. According to NASA, on Oct. 10, Chandra's X-ray observatory went into safe mode, in which the observatory is placed in a secure configuration, the essential equipment being replaced. Mounted units, the probe indicates the radii of the sun optimally for solar panels, and the mirrors are far from the sun.

Chandra is 19 years old, which is well beyond the expected five-year life. NASA extended its life by 10 years in 2001.

The US Space Agency said it is also continuing its work to resume the scientific operations of the Hubble Space Telescope, which, on October 5, is pbaded into safe mode after one of three gyroscopes (

Gyroscopes help spacecraft maintain correct orientation.

Scientists are currently conducting badyzes and tests to determine available options for re-establishing the gyro on its operational performance

Till that time, scientific operations with Hubble have been suspended

In addition to Chandra and Hubble, NASA's Kepler Space Telescope, in search of the planet, also lacks fuel. discovered about 70% of all known extraterrestrial worlds to date.

NASA's Dawn spacecraft revolves around the planet dwarf Ceres since March 2015, is also almost out of fuel and could break down as early as October. 19659002] Launchers of the Mars Space Agency, Opportunity and Curiosity, have also been facing problems recently.
