NASA launches unmanned moon shot, first in decade

The liftoff occurred just one month and two days shy of the 40th anniversary of the first lunar footprints. The mission is a first step in NASA's effort to return humans to the moon by 2020.

Scientists cheered as the Atlas V rocket carrying the two spacecraft blasted off in late afternoon, ducking through clouds and providing an exhilarating start to the $583 million mission.

"It was amazing," said John Keller, a deputy project scientist.

The two spacecraft should reach the moon in four to five days — or by early next week. One will enter into an orbit around the moon for a mapping mission. The other will swing past the moon and go into an elongated orbit around Earth that will put it on course to crash into a crater at the moon's south pole in October.

NASA expects the dramatic moon-impacting part of the mission to be "a smashing success." It's a quest to determine whether frozen water is buried in one of the permanently shadowed craters. Water would be a tremendous resource for pioneering astronauts.

"We're going to be doing some lunar prospecting, if you will, excavation style," said project manager Dan Andrews.

It's an unusual two-for-one moon shot.

The Lunar Reconnaissance Orbiter will provide a high-precision, three-dimensional map of the lunar surface. It will circle the lunar poles and, via its seven science instruments, provide a new atlas of the moon as well as a guidebook for future explorers.

When it comes time to launch astronauts to the moon, NASA wants to avoid putting them down on an uneven surface, near boulders or in a crater.

"The Apollo program accepted risk and was able to have safe landings," said Richard Vondrak, project scientist for the orbiter. "But we want to return to the moon, make repeated landings in some areas, and be able to go there with a higher degree of safety."

If the Apollo images were a hoax, the recent Japanese video may be our best look at the real surface of the moon.  One possibility NASA investigated early on was that the moon's surface would be too soft to land, that the lander would just sink into the moon dust.

I'm so used to accepting science as a virtuous endeavor -- until Hiroshima and Nagasaki, that is. Now, many years later, we are still under the nuclear pall. Next come these shots into the moon. Don't thay make you feel sad, even strange, when you stop to think about it? You do stop to think about it, don't you? The feel of it is crude, selfish, rape-like, with obvious sexual overtones. The universe is a wonderful creation far beyond our ability to understand, let alone re-create. The moon has been a source of mystery and a friend of lovers for untold centuries. It has never done anything invasive to us, and has managed to control our tides and serve as a huge terrestrial clock. It is the historical goddess of women. All things considered, I just can't feel right about invading it, blowing up its insides just out of human curiosity to see what's there and what will happen. I beg you to rethink this and all invasive space exploration.
