NASA has given the all-clear after the Hubble Space Telescope went into safe mode for the second time in weeks.
There were concerns that a problem with the telescope was causing the computer to overheat.
Earlier this month, Hubble was put into safe mode by computer glitch while in mission control.
After being put back into safe mode, the space agency confirmed that the problem had been resolved.
Hubble mission team officials said that during the last safe mode NASA had experienced a software glitch that caused a computer to keep spinning back and forth.
The computer had restarted normally, but in a second safe mode the problem had flared up again.
“We quickly determined a problem in the ‘recording’ function,” said STS-125 mission control in California, adding that the Hubble team was analyzing any further issues related to the camera.
NASA officials had received reports of unusual low temperatures of 900 degrees Celsius (1,832 degrees Fahrenheit) in the wake of the last safe mode, BBC Science correspondent Ben Summers explained.

This computer problem had been investigated during an earlier work stoppage on 24 June.
Hubble launched in 1990, and was commanded by robotic mission control to point itself at the Earth and take photographs of celestial bodies.
Its scope lets users gaze through the dusty veil surrounding the very beginning of the universe.
Among the more astonishing images of the heavens was the Hubble’s image of the spiral galaxy M51, pictured above, from a position more than 1 million light years away.
