Now approaching its 10th anniversary, NASA's Spitzer Space Telescope has evolved into a premier observatory for an endeavor not envisioned in its original design: the study of worlds around other stars, called exoplanets. While the engineers and scientists who built Spitzer did not have this goal in mind, their visionary work made this unexpected capability possible.
NASA's finally launched its Radiation Belt Storm Probes (RBSP), the first twin-spacecraft mission designed to explore the Van Allen belts.
Communication with the stranded Phobos-Grunt Martian probe is coming and going, following a first successful contact on Tuesday.

China is set to launch a Martian lander as early as 2013, according to state news agency Xinhua.
The Chinese National Space Administration says its Chang'e-2 lunar probe is ready for launch tonight from the Xichang Satellite Launch Center (XSLC) in Sichuan province.
The Japanese Aerospace Exploration Agency (JAXA) is poised to launch a probe on a two-year mission to study the weather and explore the enigmatic surface of cloud-shrouded Venus.
