Reducing the observatory to two working reaction wheels will not stop the flood of Kepler discoveries — such as the potentially life-supporting worlds Kepler-62e and Kepler-62f, which were ...

When the observatory detected the issue this week, it turned off the problematic wheel was turned off, according to a statement from NASA. This is the first reaction wheel failure in the telescope ...

NASA's $600 million Kepler Space Telescope, a leading player in the hunt for Earth-like planets orbiting sun-like stars, has been sidelined by problems with stabilizing gyroscopic reaction wheels ...

Reaction Wheel number 2 failed in 2012, so Kepler’s been running on that minimum of three for many months. With this new wheel problem, the mission itself is in danger.

Engineers are studying the reaction wheels on NASA's Dawn spacecraft after automatic sensors detected excess friction building up in one of them and powered it off early on the morning of June 17 ...

Reactions wheels of this type failed, or were deemed too unreliable to be used, on NASA’s Far Ultraviolet Spectroscopic Explorer in 2001 and Japan’s Hayabusa mission in 2004 and 2005.

The enormous spacecraft that will head to Jupiter's moon Europa uses four large reaction wheels to help keep it oriented. On 22 September, around midday, ESA's Integral spacecraft went into ...

These include two-wheel balancing robots like my Sonic the Hedgehog robot, ... What is the Difference Between Reaction Wheels and Gyroscopes. Posted: June 4, 2025 | Last updated: ...
