NASA Finds, Fixes Small Glitch in LADEE Moon Probe

Posted by timothy on from the now-for-some-space-mining-action dept.

Friday's moon-bound NASA launch from Wallops Island went well, but, says NBC News, "[H]ours after the 11:27 p.m. EDT (0327 GMT) liftoff, NASA officials reported that the spacecraft's reaction wheels — which spin to position and stabilize LADEE in space without using precious thruster fuel — unexpectedly shut down. By Saturday afternoon, the glitch had been traced to safety limits programmed into LADEE before launch to protect the reaction wheel system, NASA officials said. Those fault protection limits caused LADEE to switch off its reaction wheels shortly after powering them up, according to a mission status update. Engineers have since disabled the safety limits causing the glitch and taking extra care in restoring the fault-protection protocols."

    Maybe NASA are rocket scientists, but it seems they still have trouble getting wheels going

    Jeb would never do that. Jeb has no limits.

    Every time they had an insurmountable engineering problem, the Chief Engineer just says "override the safeties" and everything is fine. Good to know NASA is finally catching up to The Final Frontier!
