NASA’s risky maneuver to repair Hubble | Digital Trends Spanish

A team of NASA engineers has begun a major and risky maneuver to repair the Hubble space telescope, which stopped working in June of this year.

According to those in charge, the problem could be related to the power control unit that supplies a constant voltage supply to the payload computer.

For this reason, the engineers began this Thursday, July 15, to change their equipment to an alternative energy unit. Professionals have also indicated that this is a risky maneuver, which could return Hubble to its scientific observations in just a few days.

“I think they are going to be successful, but that’s not guaranteed,” said Paul Hertz, director of NASA’s astrophysics division.

The telescope has been offline since June 13, when it unexpectedly stopped working. Since then, engineers have carried out all kinds of tests and diagnostics to find out the origin of this failure.

This week, managers discovered that the malfunction could be due to a faulty power regulator.

The risk factor happens because the malfunctioning unit is linked to many other components and control systems, which are part of the telescope’s scientific instruments.

NASA has to change them all. Thus, once this operation is completed, the parts involved will no longer have backup copies in case of a future error. If this were to happen, it could spell the ultimate end of the space telescope.

“You can’t see the spaceship, you can’t see how it happens. You have to make sure your command payloads will do exactly what you intend them to do, ”adds Hertz.

“You don’t want to accidentally turn off the radio receiver. You don’t want to accidentally change a battery that’s not ready to be changed… We just don’t want to accidentally break anything. “
