CHINESE SPACE STATION TO DISINTEGRATE

CHINESE SPACE STATION TO DISINTEGRATE: China's Tiangong-1 space station is about to return to Earth--as a massive fireball. Low solar activity kept Tiangong-1 in orbit longer than officials predicted, but it's finally coming down. The European Space Agency says the 8-ton craft should re-enter sometime between March 30th and April 2nd, a window of uncertainty which will narrow in the days ahead.
