Steady As She Goes: New Horizons Successfully Completes Small Course Correction Prior to Pluto Encounter

An artist’s concept of NASA’s New Horizons spacecraft during its closest approach to Pluto and Charon on July 14. With just four weeks remaining before this much-anticipated spaceflight event, New Horizons remains healthy and on course for its rendezvous with history.

Voyager 1 Detects 'Tsunami' Wave From Sun Still Going Strong Beyond the Heliopause

An artist’s concept of Voyager 1 against a backdrop of stars. Having crossed into interstellar space, the spacecraft has detected that a shockwave from a Coronal Mass Ejection which was blasted from the Sun more than a year ago, is still travelling outward into the interstellar medium.

Cosmic Ray Hit Causes Small Delay at Dawn's Rendezvous With Ceres Early Next Year

An artist’s concept of NASA’s Dawn spacecraft exploring Vesta and Ceres in the asteroid belt between Mars and Jupiter. Dawn had recently experienced an anomaly in its ion propulsion system resulting from a cosmic ray hit, which will cause a small delay to the spacecraft’s rendezvous with Ceres next year.

Hubble Discovers Two Potential KBO Targets for NASA's New Horizons Spacecraft, Follows Up With Additional Search

Discovery images of the two Kuiper Belt Objects named 1110113Y and 0720090F respectively, taken with NASA’s Hubble Space Telescope. The image at left shows the first KBO at an estimated distance of approximately 4 billion miles from Earth. Its position noticeably shifts between exposures taken approximately 10 minutes apart. The image at right […]

ESA's Rosetta Spacecraft Closes In on Comet 67P/Churyumov-Gerasimenko, Detects Huge Amounts of Water Outgassing

ESA’s Rosetta spacecraft, which is presently en route to the comet 67P/Churyumov–Gerasimenko, has detected that the comet’s nucleus outgasses huge amounts of water vapor each second, despite its current distance of approximately 3.7 Astronomical Units from the Sun. Image Credit: ESA

NASA's Cassini Spacecraft Conducts Important Science During Several Flybys of Titan, Probes Its Enigmatic Seas

A view of the night side of Titan taken by the Cassini spacecraft, which captures the blue halo caused by a haze layer that hovers high in the moon’s atmosphere. The spacecraft conducted several flybys of the moon in recent months, during which it beamed a series of radio waves through its atmosphere, […]
