ESA's Gaia mission launched successfully on a Soyuz-Fregat rocket from Kourour, French Guiana at 09:12 UT on 19 December 2013. The mission is designed to measure the positions and velocity of roughly 1,000,000,000 stars as well as determine their temperature, composition, and other properties. More...

NASA's Wide-field Infrared Survey Explorer (WISE) satellite has released data from the first 57% of the sky surveyed during the mission. The satellite went into hibernation in early February 2011, but its discoveries include 20 comets, more than 33,000 asteroids between Mars and Jupiter, and 133 near-Earth objects. More...

NASA's launch of the Interface Region Imaging Spectrograph (IRIS) spacecraft took place at 7:27 p.m. on 27 June 2013 (02:27 UT, 28 June) about 100 miles from Vandenberg AFB. More...

Voyager 1 has encountered a region of spacecraft at the edge of our solar system that scientists believe is the last region the spacecraft will have to cross prior to entering interstellar space. More...

The European Space Agency Philae Lander has gone into hibernation on comet 67 P/Churyumov-Gerasimenko after its last communication session on 15 November. The lander completed its main scientific mission despite ending up in a shadowed area which did not provide the planned solar power. For more, see the ESA Release and http://rosetta.esa.int/

China's Chang'e 5 Test Vehicle capsule successfully landed near Huofutan in Inner Mongolia after rounding the Moon and re-entering the atmosphere at roughly 22:00 UT (6:00 p.m. EDT) on October 31 (6:00 a.m. local Chinese time, Nov. 1).

Comet Siding Spring flew by Mars at a distance of about 139,500 km (87,000 miles) on Sunday, 19 October at 18:27 UT (2:27 p.m. EDT). Many of the spacecraft currently operating at Mars observed the comet, all were in good health following the comet's passage. For more information, see the NASA Siding Spring Comet page.
