One of the planet-hunting Kepler space telescope’s reaction wheels — devices that maintain the observatory’s position in space — remains balky despite mitigation attempts, NASA said April 29. The ...

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 ...

WASHINGTON — A reaction wheel on NASA’s Kepler spacecraft continues to experience elevated levels of friction after a brief rest period, but project officials say that does not necessarily imply an ...

This artist’s concept depicts Kepler-62e, a super-Earth-size planet in the habitable zone of a star smaller and cooler than the sun, located about 1,200 light-years from Earth in the constellation ...

LAFAYETTE, Colo.--(BUSINESS WIRE)--Small-satellite manufacturer and mission services provider Blue Canyon Technologies LLC ("BCT" or "Blue Canyon"), a wholly-owned subsidiary of Raytheon Technologies, ...

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, ...

Last week, the Kepler spacecraft software detected an abnormal drift in the pointing of the observatory. As it was designed to do, the software sent the spacecraft into safe mode (putting the ...

Rocket Lab USA Inc. has released two products aimed at the small-satellite market. The Long Beach company debuted earlier this month a software-defined radio, plus a reaction wheel used for attitude ...

The inverted pendulum is a pretty classic dynamics problem and reaction wheels are cool. That’s why we like [Mike Rouleau]’s self-balancing stick. The video, viewable after the break, was fairly ...
