NASA’s Hubble Space Telescope (HST) went into “safe mode” on Sunday after what the agency called a “software error.”
NASA announced the issue in a tweet Sunday, writing that around 4 a.m. ET, the HST “went into safe mode due to an onboard software error.”
HUBBLE TELESCOPE SOLVES THE MYSTERY OF STAR GRADATION
“The Hubble Space Telescope is in good condition but remains in Safe Mode as a precaution as the team works to fully understand the error encountered on Sunday and the associated Safe Mode response,” NASA said Tuesday. at Fox News. “The team is working to get Hubble back to science operations as soon as possible.”
Safe Mode is a setting that places the telescope in a “stable configuration that suspends scientific observations” and positions the HST’s solar panels toward the sun to ensure that its energy needs are met.
“The spacecraft remains in this configuration until ground control can correct or compensate for the problem,” NASA explained in an article in 2018. “The rest of the spacecraft and its instruments are still fully functional and should produce excellent science for years to come. come.”
NASA’s Hubble Space Telescope maintains its orbit around the Earth.

This is not the first time the telescope has entered Safe Mode.
On October 5, 2018, the spacecraft entered Safe Mode due to a faulty gyroscope, and on June 15, 2009, the HST Science Instrument Command and Data Handler (SI C&DH) began sending unexpected “zero” readings to edge. The HST 486 computer requests that Safe Mode be enabled.
It’s unclear how long it will take to restore functionality this time around.
In 2018, HST’s security measures were in place for three weeks before the team could relaunch the telescope.

A joint venture between NASA and the European Space Agency, the HST launched into orbit in April 1990 aboard the space shuttle Discovery.
Since then, the telescope has delivered amazing images of the universe with over 1.4 million observations during its lifetime.
