Comet ISON Streams Toward the Sun

In the early hours of Nov. 27, 2013, Comet ISON entered the field of view of the European Space Agency/NASA Solar and Heliospheric Observatory. In this picture, called a coronagraph, the bright light of the sun itself is blocked so the structures around it are visible. The comet is seen in the lower right; a giant cloud of solar material, called a coronal mass ejection or CME, is seen billowing out under the sun. Comet ISON, which began its trip from the Oort cloud region of our solar system, will reach its closest approach to the sun on Thanksgiving Day, skimming just 730,000 miles above the sun's surface. NASA is tracking Comet ISON's journey and hosting events to discuss what the public worldwide may see as the comet traverses the sun.

DSCS B-10 turns 20

The 3rd Space Operations Squadron will celebrate the Defense Satellite Communications System B10 satellite's 20th anniversary on orbit Nov. 28. The anniversary holds significant importance for the squadron and for the Air Force, in part because it was designed to operate for only 10 years.

Launched from Cape Canaveral, Fla., Nov. 28, 1993, DSCS B-10 was designed to provide wideband military communications to U.S. Strategic Command users. Following launch it was positioned over the Indian Ocean and served in the active DSCS constellation for more than 18 years before transitioning to a test asset in 2012.
