Earth's Shadow: Time-Lapse Video of the Total Lunar Eclipse of 12/10/11

I woke up at 4:00 am this morning in order to take some video of the last total lunar eclipse visible from North America till 2014. The eclipse was beautiful. It was amazing to watch the shadow of our planet creep slowly across our nearest neighbor. Once the shadow was blocking out most of the light from the sun, the moon was significantly dimmer and the color had changed to a reddish orange. This color is caused by the same effect that makes our sunrises and sunsets so colorful. The light fr...

How To: Get Rid of All that Space Junk

How about a laser? One that is strong enough to nudge debris out of earth orbit. That's what NASA contractor James Mason wants to do, and his lab simulations suggest that the idea is possible. Mason wants to use a 5kW ground-based laser and a ground-based 1.5 meter telescope to spot potentially hazardous space waste and shove it off, by about 200 meters per day of lasering. It's kind-of like air traffic control for near earth orbit.
