Planetary Society volunteer Ken Kremer is reporting for us from the Kennedy Space Center, where he witnessed the launch of Space Shuttle Atlantis to the Hubble Space Telescope on May 11. Kremer is a research scientist and freelance journalist who spends his spare time giving public outreach presentations on behalf of The Planetary Society as a volunteer and NASA's Jet Propulsion Laboratory as a Solar System Ambassador. He also enjoys creating Mars mosaics. Thanks Ken!

The Lunar Reconnaissance Orbiter, or LRO, is NASA's next science flight dedicated to explore and survey Earth's moon and pave the way to return a human presence. In fact, it's actually two robotic pathfinder missions in one. Riding piggyback is the co-manifested Lunar Crater Observation and Sensing Satellite, or LCROSS.
LRO and LCROSS at Astrotech Payload Facility
ASA's LRO (gray) and LCROSS (yellow) lunar spacecraft stacked adjacent to Atlas V payload fairing at Astrotech Payload Facility on May 15, 2009 during media photo opportunity and briefing. "Germanium blankets control heat flow in and out of the spacecraft. The radiators will reject heat to control the internal temperature. The plan is to maintain a normal internal temperature for the electronics of 0 to 45 C," according to Nick Virmani.
he two spacecraft will provide complimentary data from different vantage points in unprecedented detail and are set to launch no earlier than June 17. Whereas LRO will study the lunar composition and environment from polar orbit, LCROSS is designed to impact a crater near the lunar polar region, hunt for water ice and provide ground level composition data.
I observed the integrated LRO and LCROSS combination spacecraft stack up close on Friday, May 15, at the Astrotech Space Operations Facility, Titusville, FL, located a few miles west of KSC. I participated in a media tour sponsored by NASA for a pre-launch photo opportunity and Q&A with mission scientists and engineers.

RO is managed by NASA Goddard Spaceflight Center. LCROSS is the responsibility of the NASA Ames Research Center in Moffett Field, CA. The LRO/LCROSS mission hopes to discover what the moon has to offer for future moon dwellers. This includes searching for safe landing sites and life sustaining elements such as water and constitutes a major step by NASA towards returning humans to the moon by 2020.
The spacecraft are undergoing final processing before launching aboard an Atlas V rocket from Cape Canaveral Air Force Station (CCAFS), FL. CCAFS lies adjacent to the Kennedy Space Center.
LRO with Protective Blankets
RO spacecraft (top) protected by gray colored blankets is equipped with 6 science instruments located at upper right side of spacecraft. Payload fairing in background is a molded structure that fits flush with the outside surface of the rocket and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch and ascent.
