PRIANGAN ZONE – Hubble Space Telescope NASA broken and struggling to understand most serious problem from that observatory in more than a decade.
Hubble stopped working suddenly June 13 when astronomers used the 31-year-old telescope to examine a star pulsing 200 million miles away.
NASA is trying to understand what went wrong with orbiting telescopes, without which hundreds of astronomical investigations had to be postponed or cancelled, then at stake is an attempt to understand galaxies, comets, stars, exoplanets, and the entire universe.
Engineers have been trying to restart the $1.5 billion telescope, which is about 43 feet long — the length of a typical school bus — and named after astronomer Edwin Powell Hubble, who made a number of important discoveries before he died in 1953.
The team is preparing a technique to activate secondary regulators that control data and power, says director of astrophysics NASA Paul Hertz in an interview. Hardware that failed at the regulator was most likely the cause, he said, as quoted by ZonaPriangan from UPI.com, July 12, 2021.
“Almost everything at Hubble, with a few exceptions, is completely redundant, meaning there’s a backup in case something goes wrong,” Hertz said. “We can’t say for sure what went wrong, but we think it was a failure in the component we were trying to isolate.”

He said a solution was “possible”, but acknowledged there was a slim chance that repairs from Earth would be impossible.
