The Hubble Space Telescope should last for at least 5 years

NASA's Hubble Space Telescope does not allow the termination of some broken parts.

A number of reports suggest that the spacecraft has a "strong chance" lasting for at least another five years until the mid-2020s.

"At present, all subsystems and tools have a reliability that exceeds 80% by 2025," said Thomas Brown, Head of Mission at the Space Science Institute of Space Telescope in Spaceland.

Brown presented the results last week at a meeting of the American Astronomical Society in Seattle.

Positive diagnosis occurs a week after engineers suspended Hubble 3's broad camera operations due to an unspecified hardware problem.

Team members have attributed the problem of telemetry rather than a power problem – in this case, a simple turn-off-and-on-again solution has brought WFC3 into operation.

All values ​​were normal. Calibration and additional tests will be performed within the next 48 to 72 hours to ensure that the instrument is working properly, "NASA announced on Tuesday.

"Assuming that all tests work as planned, it is expected that Wide Field Camera 3 will begin to collect the images of science again by the end of the week," according to a blog post.

WFC3 was installed during Hubble's last mission in 2009, when astronauts introduced the Cosmic Origins Spectrograph. After a decade of space, both tools still have their online backup systems, which could help extend their life span.

"If there are redundancy systems [as] trustworthy [as the primaries], we can get many more years, "Brown said.

The Hubble Space Telescope, at the same time, is in its 29th year – far exceeding its life span of 15 years.

Since the launch of the iconic spacecraft in Earth's low orbit in 1990, five Space Shuttle missions have repaired, upgraded and replaced its systems, including the five main tools.

The Hubble orbit is stable until the 2030s, when it will collapse in the atmosphere of the Earth and burn before it touches the earth. James Webb Space Telescope (JWST) scheduled to be lifted in March 2021 will replace the Hubble.
