TravelGuides – NASA will attempt a ‘dangerous’ maneuver to fix its broken Hubble Space Telescope as early as next week

NASA’s Hubble Space Telescope has been offline for practically a month.


The telescope’s payload pc – a Nineteen Eighties machine that controls and screens all the spacecraft’s science devices – suddenly stopped working on June 13. Engineers have been troubleshooting the problem since then, however with little success.


However, a recent NASA announcement suggests a glimmer of hope: The agency tweeted on Thursday that it had efficiently examined a process that might change components of the telescope’s {hardware} to their again-up elements.

This may pave the best way for the payload pc to come again on-line, main to the restart of Hubble’s scientific observations.

NASA reported the process may occur as early as next week, following further preparations and critiques. The telescope and the scientific devices on board stay in working situation.

But the change will be “risky,” in accordance to NASA astrophysics division director Paul Hertz.

“You can’t actually put your hands on and change hardware or take a voltage, so that does make it very challenging,” he told New Scientist.

NASA has efficiently switched Hubble over to its again-up {hardware} earlier than

Hubble is the world’s strongest house telescope; it orbits 353 miles above the Earth.

On June 30, NASA introduced it had found out that the supply of the payload pc drawback was in Hubble’s Science Instrument Command and Data Handling unit (SI C&DH for brief), the place the pc resides.

“A few hardware pieces on the SI C&DH could be the culprit(s),” NASA said.

Backup items of {hardware} are pre-put in on the telescope. So it is simply a matter of switching over to that redundant {hardware}. But earlier than making an attempt the tough change from Earth, engineers have to apply in a simulator, the company added.

NASA has rebooted Hubble utilizing this sort of operation prior to now. In 2008, after a pc crash took the telescope offline for 2 weeks, engineers successfully switched over to redundant {hardware}. A 12 months later, astronauts repaired two broken devices whereas in-orbit – Hubble’s fifth and final reservicing operation. (NASA doesn’t presently have a approach to launch astronauts to the house telescope.)

Getting the observatory again on-line is vital to NASA.

“Hubble is one of NASA’s most important astrophysics missions. It’s been operating for over 31 years, and NASA is hopeful it will last for many more years,” an company spokesperson told Insider in June.

Hubble, which launched into orbit in 1990, has captured images of the births and deaths of stars, found new moons round Pluto, and tracked two interstellar objects as they zipped by our photo voltaic system. Hubble’s observations have additionally allowed astronomers to calculate the age and growth of the universe and to peer at galaxies fashioned shortly after the Big Bang.
