Hubble Space Teleskop Zeitleiste

By Duncan Mil

June 7, 2024 - In mehr als drei Jahrzenten im All hat NASAs Hubble Weltraumtelekop das Gebiet der Astronomie verändert. Seine ständigen wissenschaftlichen Entdeckungen haben unser Wissen über das Universum komplett verändert, allerdings ist Hubble seit Mai 2024 auf "safe mode" gesetzt.

“It’s just made these huge contributions. It’s re-written a lot of what we know,” said Hubble astronomer Adam Riess, who shared the 2011 Nobel Prize in physics for his work verifying the existence of dark energy.

The safe-mode event is the latest of several that have suspended the telescope’s science operations. Most of these disruptions are linked to faulty readings from a gyroscope, or gyro, that enables Hubble to track targets across the sky.

Hubble’s six gyros were all replaced in 2009 during the last space shuttle mission to service the telescope. Now, Hubble is down to two good gyros to steer and point the telescope.

During a press conference on Tuesday (June 4), Mark Clampin, director of NASA’s astrophysics division, announced that the space agency is transitioning Hubble to “one-gyro mode,” as a contingency plan.

“Operationally, we believe this is our best approach to support Hubble science through this decade and into the next since most of the observations it takes will be completely unaffected by this change,” said Clampin.

The one-gyro mode uses Hubble’s magnetometers and sun sensors with one gyro to determine the spacecraft’s orientation to the Earth and Sun.

NASA aims for Hubble to resume operations with its new configuration in mid-June.
