Lunar Orbiters Survive Eclipse With Flying Colors

EclipseOrbiters0414

LRO Survives 2 Consecutive Orbits Going Straight From Moon Shadow To Earth Shadow; LRO Twitter Account Reports Probe Instruments Dropped To 15° C; Engineers Were Less Confident That LADEE Would Survive Cold, In Normal Orbit Probe Is Deprived Of Sunlight For 1 Hour, During Eclipse It Survived 4 Hours Of Shadow; Mission Team Received Yellow Then Red Alarms As Power / Temperatures Dropped, Once Sunlight Returned All Returned To Normal, Allowing Spacecraft To Continue Collecting Valuable Data While Gradually Reducing Altitude
