Fly me to the Moon — and then crash! Spectacular footage from the two GRAIL spacecraft just prior to their lunar impact.

Two teams competing for the Google Lunar X-Prize have now merged.

Moon Express had been considered by some to be in the lead to win the $30 million prize. With this merger I suspect their chances have improved considerably.
China’s 2013 missions: another manned flight and a lunar landing.
The competition heats up: China in 2013: another manned flight and an unmanned lunar landing.
Scientists have found the source of the water on the Moon and Mercury: the solar wind.
Scientists have found the source of the water on the Moon and Mercury: the solar wind. Key paragraph:
“We found that the ‘water’ component, the hydroxyl, in the lunar regolith is mostly from solar wind implantation of protons, which locally combined with oxygen to form hydroxyls that moved into the interior of glasses by impact melting,” said Zhang, the James R. O’Neil Collegiate Professor of Geological Sciences. “Lunar regolith is everywhere on the lunar surface, and glasses make up about half of lunar regolith. So our work shows that the ‘water’ component, the hydroxyl, is widespread in lunar materials, although not in the form of ice or liquid water that can easily be used in a future manned lunar base.” [emphasis mine]
Though this result would explain the detection of hydrogen on the lunar surface and would also mean that this hydrogen is far less useful for future colonists than previously hoped, it doesn’t eliminate the possibility that there is ice in the permanently shadowed craters near the lunar poles that came from other as yet unknown sources.
A competitor has debuted its full-size prototype rover designed to hunt for water in the craters of the Moon.
The Google Lunar X-Prize: One competitor has unveiled its full-size prototype rover, designed to hunt for water in the craters of the Moon.
The company, Astrobotic Technology, is consider to be in second place in the race to build the first private lunar rover.
The first results from the two GRAIL space probes have revealed the Moon has a much thinner crust than previously believed.
The uncertainty of science: The first results from the two GRAIL space probes have revealed that the Moon has a much thinner crust than previously believed.
These preliminary results have also found that the Moon’s surface topography closely matched the variations in the gravitational field, and that there appears no evidence in the gravitational field of the giant ancient impact basins that scientists have for decades assumed were there, based on surface evidence. This last result is especially surprising, and will force an almost complete rewrite of the Moon’s geological history.
Interestingly, these results are only peripherally related to GRAIL’s main research goal, which was to map the Moon’s deep structure and core. I suspect there are even more surprises coming when this data gets released.
There’s a Light – We Choose to go to the Moon
An evening pause: A song by a band called There’s a Light, from their 2012 album Khartoum, expressing nicely in words, music, and images the human insistence on doing great things.

One reason why Neil Armstrong got the job
An evening pause: This short clip from the Discovery Science series Rocket Science illustrates one reason Neil Armstrong got the job to land the first spacecraft on the Moon, even though it shows Armstrong crashing his test vehicle!
The man was cool-headed. Not only did Armstrong not panic when a thruster failed, he kept trying to regain control of the craft until the last moment, ejecting less than a second before impact. Then, he was calm about it afterward, hardly mentioning the incident to others.
Neil Armstrong
I think the gracious statement by Neil Armstrong’s family sums up his life quite well.
We are heartbroken to share the news that Neil Armstrong has passed away following complications resulting from cardiovascular procedures.
Neil was our loving husband, father, grandfather, brother and friend.
Neil Armstrong was also a reluctant American hero who always believed he was just doing his job. He served his Nation proudly, as a navy fighter pilot, test pilot, and astronaut. He also found success back home in his native Ohio in business and academia, and became a community leader in Cincinnati.
He remained an advocate of aviation and exploration throughout his life and never lost his boyhood wonder of these pursuits.
As much as Neil cherished his privacy, he always appreciated the expressions of good will from people around the world and from all walks of life.
While we mourn the loss of a very good man, we also celebrate his remarkable life and hope that it serves as an example to young people around the world to work hard to make their dreams come true, to be willing to explore and push the limits, and to selflessly serve a cause greater than themselves.
For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.
