Best Mars Sky Show of the Year to Happen Saturday
by Mike Wall
Mars will make a close approach to Earth Saturday (March 3), and interested skywatchers can follow the action live online. Every 26 months, the orbits of Earth and Mars align such that the two planets form a relatively straight line with the sun. This cosmic event is called an opposition, because the Red Planet sits on the exact opposite side of Earth from the sun…

The composite image was assembled from image data captured from a number of swaths of Earth’s surface on Jan. 4 and is the best-known high-resolution images of our planet.

Four NASA astronauts from the final space shuttle mission tonight presented host Stephen Colbert with a pretty fucking cool artifact — a “frangible nut.” As Commander Chris Ferguson explained,
The space shuttle is actually held to the launch pad with eight very large nuts. …At the moment that the solid rocket boosters — the big white ones — fire, there’s charges in either side of that nut that will split that nut in half and actually release the space shuttle from the state of Florida (!!!) so that it may ascend in(to) orbit.
Stephen then snarked, “As if launching a rocket were not phallic enough, you literally bust a nut when you go into space.”
Learn something new every day! Also, may your nuts never be frangible.
