Astrophysics

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...

Lunar and Planetary Science

The New Horizons spacecraft will reach Pluto on July 14, closest approach during the flyby will occur at 11:50 UT (7:50 a.m. EDT).

The Philae lander reestablished contact on 13 June after 7 months of silence on the surface of Comet 67P/Churyumov-Gerasimenko. The lander has had a couple of short communications sessions with the Rosetta orbiter and appears to be in good condition. More details are available in the 15 June ESA Bulletin.

NASA's MESSENGER spacecraft ended its mission as planned with an impact on the surface of Mercury April 30 at 19:26 UT (3:26 p.m. EDT). The estimated impact position was 54.4 N, 210.1 E. A last image was returned shortly before the impact. For more details on the end of the mission, see the MESSENGER News Release.
