...flew. The ship will be fairly stuffed with scientific instruments, one of the most important - if least sexy sounding - of which will be its laser altimeter. The altimeter will bounce laser beams off the lunar surface and, by measuring the speed at which they reflect back up, calculate the moon's topography to within inches. That's critical since long-term lunar stays require finding not only hospitable places to land, but also hospitable places to establish a home. (See the space moon race...
Just as important for choosing where to homestead is knowing the local weather - or at least the local temperature. Nobody pretends that the moon will be a thermally comfortable place to live, but few people realize just how punishing its climate extremes are - a torch-like 250 degrees Fahrenheit (120 Celsius) during the day and a paralyzing -382 Fahrenheit (-230 Celsius) at night. What's more, says Garvin, "the moon goes through this dance every 28 days." Those kinds of cycling extremes can be murder on hardware, and until we know more about the hot-cold rhythm...
...seconds before touchdown. That's less likely to happen this time, thanks to a camera that can visualize objects as small as a few feet across. What's more, since the LRO will be in a polar orbit instead of an equatorial one - or, vertical rather than horizontal - the moon's 28-day rotation will eventually carry virtually every spot on the surface beneath the camera's lens...
...moon will essentially walk around underneath the orbiter," says Garvin. "With the detail we get in the photographs, every picture will be like a mini-landing." That includes photos of the Apollo sites, all half-dozen of which should have their portraits snapped. If NASA gets lucky, Garvin believes the first such images could be in hand by the 40th anniversary of Apollo 11, on July...
...much precision is look for water. That's a problem, since astronauts living on the surface will need plenty of the stuff, and bringing it all with them is out of the question. (A single pint of water weighs about a pound, and every pound you fly to the moon costs about $50,000.) The LRO, however, will not be traveling alone. Launched on the same booster will be another entire spacecraft known as the Lunar Crater Observation and Sensing Satellite (LCROSS...
