SES completes three-satellite procurement with Ariane 5 contract
SES has selected Arianespace to launch a communications satellite ordered as part of a three-spacecraft procurement announced last month, after assigning the other two payloads for launches aboard SpaceX Falcon 9 rockets.
NASA orders missions to resupply space station in 2017
NASA has ordered four additional launches to deliver cargo to the International Space Station in 2017 -- three from SpaceX and one from Orbital ATK -- to cover the research lab's logistics needs until a new set of resupply contracts take effect.
Glitch on Curiosity rover traced to drill mechanism
Officials are assessing how to adjust operations to collect future rock core samples with NASA's Curiosity Mars rover after identifying its drill as the likely source of a short circuit that stopped the rover's movement in late February.
Dawn arrives for the first exploration of a dwarf planet
NASA's Dawn spacecraft slipped into orbit around the dwarf planet Ceres on Friday, ready to examine the largest unexplored world in the inner solar system after traveling 3.1 billion miles from Earth.
Engineers analyzing short circuit on Mars rover
A short circuit that halted movement of NASA's Curiosity Mars rover is not expected to keep the mobile robot stationary for long, but engineers want to know whether the problem will restrict some future science operations.
Crunch time: Next Mars lander enters final year before launch
Wednesday marked one year until the launch of a NASA seismic station to Mars, and scientists believe they have found a suitable operating post for the lander as engineers race to keep the mission on schedule for liftoff in a narrow 26-day window next March.
Power system failure likely cause of military satellite explosion
The U.S. Air Force says a temperature spike in the power system of a nearly 20-year-old weather satellite may have led to the spacecraft's explosion in orbit, scattering more than 40 fragments of debris that could be flying around Earth for decades.
Liftoff of Indian navigation satellite postponed
The launch of a satellite for India's indigenous navigation network has been postponed to resolve a problem with one of the spacecraft's radio transmitters, officials said Wednesday.
Photos: Last look at Sunday’s launch by SpaceX
Sunday's liftoff of a Falcon 9 rocket marked the 16th flight of SpaceX's workhorse launcher, and its third mission of the year. Here is another set of launch photos from SpaceX.
Rosetta glimpses its own shadow on comet 67P
The sharp-eyed science camera on Europe's Rosetta comet orbiter caught a view of the probe's fuzzy shadow when controllers guided the spacecraft just a few miles over its subject's nucleus last month.
