NASA Says It's Trying to Bring the Hubble Back Online

NASA is working on bringing the Hubble Space Telescope back online, but given its recent setbacks, the agency's insistence that it's "in good health" may be wishful thinking.

In an update, NASA said that it's still working to bring the aging telescope back to life after a series of issues that led it to automatically enter safe mode (read: shut down) three times over the course of a few weeks, with the final one lasting until now.

Starting on November 19, the agency began having issues problems with the gyroscopes or "gyros"? which helps orient the telescope in whatever direction it needs to point. Between that date and November 29, the gyro issues led to automatic power-downs thrice. That last safe mode, it seems, has remained in effect until now.?

These latest Hubble setbacks have resurrected talks of a private servicing mission for the 33-year-old telescope that was supposed to be decommissioned nearly two decades ago.

At the end of 2022, NASA and SpaceX announced that they were jointly looking into whether it would be feasible to send up a private mission "at no cost to the government" to fix various issues on the telescope. That study has apparently been completed, but nobody knows what the findings were just yet.

X-37B

Space Force sets Sunday night liftoff time for X-37B space plane's mystery mission in orbit

After the Space Force's robotic X-37B Orbital Test Vehicle launches again Sunday night, what types of classified payloads will it carry into space??

And how long will the black-and-white miniature space shuttle remain in orbit — considering that its last marathon flight lasted 908 days??

“It's a test platform that allows them to collect a bunch of data in a relatively controlled environment in the cargo bay of the space plane, the X-37B, over a period of time in orbit and see how well those sensors perform, how well they are immune to the radiation environment of space," said Don Platt, director of the Florida Institute of Technology's Spaceport Graduate Center in Titusville.?

"And then they can bring it back to the Earth for further analysis — which is a tremendous advantage over just launching a satellite in orbit and collecting data from it. Because at the end of the mission, you normally don't have any way to get that satellite back," Platt said.?

This Week in Space History

First ham contact from space?

Early on the morning of December 1, 1983, NASA Astronaut Owen Garriott, W5LFL, talked with Lance Collister, WA1JXN in Frenchtown, Montana. The contact was unique because it was the first Space to Ground contact. The STS-9 activity was the first to enable ham radio from space.?

December 7, 1995?

Galileo was an American robotic space probe that studied the planet Jupiter and its moons, as well as the asteroids Gaspra and Ida. Named after the Italian astronomer Galileo Galilei, it consisted of an orbiter and an entry probe. It was delivered into Earth orbit on October 18, 1989, by Space Shuttle Atlantis , during STS-34. Galileo arrived at Jupiter on December 7, 1995, after gravitational assist flybys of Venus and Earth, and became the first spacecraft to orbit an outer planet?

Apollo 17

Apollo 17 (December 7–19, 1972) was the eleventh and final mission of NASA's Apollo program, the sixth and most recent time humans have set foot on the Moon or traveled beyond low Earth orbit. Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon?
