Dusk for Dawn: NASA's Groundbreaking Mission Comes to an End
After 11 Years, NASA's Dawn mission to explore Vesta and Ceres is about to come to an end.
The Kepler Space Telescope Comes to an End
NASA's planet-hunting telescope has run out of fuel after a nine-year mission that found more than 2,600 planets orbiting other stars along with thousands more worlds yet to be confirmed.
After Brief Shutdown, Hubble Goes Back to Work
Following three weeks of downtime, engineers have cleared out a mechanical blockage in one of Hubble's gyroscopes and returned the observatory to full science operations.
Mission to Mercury Launches
The BepiColombo spacecraft, Europe's first mission to Mercury, rocketed away from Earth to begin its seven-year trek to the innermost planet.
Voyager 2 Approaches Interstellar Space
An increase in cosmic rays indicates that Voyager 2 is approaching the heliopause, where the solar wind gives way to the interstellar medium.
Hubble Hibernates After Minor Breakdown
A failure of a gyroscope used to point and stabilize the Hubble telescope caused the observatory to safely shut down while engineers determine a fix.
