DARPA's Space Surveillance Telescope (SST) seeks to enable much faster discovery and tracking of previously unseen, hard-to-find small objects in geosynchronous orbits. The SST will soon move from its current mountaintop location in New Mexico, where the system underwent operational testing and evaluation, to Australia, where it will provide key space situational awareness from the southern hemisphere—an area of the geosynchronous belt that is still largely unexplored. Credit: DARPA

Comet ISON, which began its journey from the Oort Cloud some 3 million years ago, made its closest approach to the sun on Nov. 28, 2013. The comet was visible in instruments on NASA's Solar Terrestrial Relations Observatory, or STEREO, and the joint European Space Agency/NASA Solar and Heliospheric Observatory, or SOHO. Credit: NASA

NASA's Firefly mission, funded by the U.S. National Science Foundation, will study the possible relationship between Earth lightning and gamma ray emmissions. By using a cubesat, the Firefly mission provides a low-cost approach to high-quality, highly targeted science. It was among the 29 satellites launched Nov. 19 on the Minotaur 1 rocket from Wallops Island, Va. Credit: NASA Goddard
