LADEE Spacecraft Meets End,
Science Data Analysis Continues

LADEE Spacecraft End

LADEE Orbiting At ~5,793kph Collected Valuable Science Data & Mimicked Surveyor / Apollo ‘Twilight Ray’ Observations With Star Tracker At ~91-Meter Altitude Prior To Far-Side Impact 17 Apr Between 21:30-22:22 PDT, Possibly Smashing Into Lunar Crater Or Mountain Ridge; Will Take More Than 1 Year To Analyze Successful US$280M Mission Data Including LDEX Characterization Of Ejecta Cloud & Perturbations From Chang’e-3 Landing; Completion Of 5th USA Moon Orbiter Mission Since Apollo Era, No Controlled Landings Achieved After 1972

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
