Crescent Earth from the Departing Rosetta Spacecraft

Explanation: Goodbye Earth. Earlier this month, ESA’s interplanetary Rosetta spacecraft zoomed past the Earth on its way back across the Solar System. Pictured above, Earth showed a bright crescent phase featuring the South Pole to the passing rocket ship. Launched from Earth in 2004, Rosetta used the gravity of the Earth to help propel it out past Mars and toward a 2014 rendezvous with Comet Churyumov-Gerasimenko. Last year, the robot spacecraft passed asteroid 2867 Steins, and next year it is scheduled to pass enigmatic asteroid 21 Lutetia. If all goes well, Rosetta will release a probe that will land on the 15-km diameter comet in 2014.

“What went wrong: An O-ring failure in a solid rocket booster led to leaking of hot gases against the external tank. The resulting explosion killed the seven member crew.
NASA was frenetic over publicizing the teacher in space angle, even to the extent of compromising mission safety. When the launch was delayed, meaning the flight day McAuliffe was to teach her ‘lesson from space’ was moved from a weekday to a weekend, NASA took the unprecedented move of ordering the flight schedule to be rearranged so the lesson would instead be given on a school day. The training and planning of months had to be revised in hours. Payload specialist Jarvis was on this flight only because his original crew assignment had been deleted when Congressman Bill Nelson claimed a seat on the flight. Jarvis, an employee of Hughes, was supposed to be making observations of satellite deployment. But since there was no Hughes satellite aboard Challenger, the assignment made no sense. Exploded 73 seconds after launch, all seven crewmembers were killed and the TDRSS satellite aboard was destroyed. The crew cabin remained intact after the shuttle Challenger disintegrated. Indications that emergency oxygen supplies were manually activated showed that some crew members may have remained alive until the cabin hit the ocean.”

Water Discovered in Moon Shadow, AND A FACE

I spotted a face..
Why is there water on the Moon? Last month, the LCROSS mission crashed a large impactor into a permanently shadowed crater near the Moon’s South Pole. A plume of dust rose that was visible to the satellite, although hard to discern from Earth. The plume is shown above in visible light. Last week, the results of a preliminary chemical analysis gave a clear indication that the dust plume contained water. Such water is of importance not only for understanding the history of the Moon, but as a possible reservoir for future astronauts trying to live on the Moon for long periods. The source of the lunar water is now a topic of debate. Possible origins include many small meteorites, a comet, or primordial moon soil.

The longest solar eclipse of the century
Earlier today, the moon passed directly in front of the sun, causing a total solar eclipse that crossed nearly half the Earth – through Nepal, Bangladesh, Bhutan, Myanmar and China. Today\’s was the longest total solar eclipse of the 21st century, lasting as much as 6 minutes and 39 seconds in a few areas.
