Expedition 39 is relaxing the day after a short spacewalk to replace a backup computer. The crew members are also preparing to welcome back a Russian resupply freighter that undocked a couple of days ago.
NASA astronauts Rick Mastracchio and Steve Swanson successfully replaced a backup multiplexer/demultiplexer computer Wednesday morning during a spacewalk that lasted just one hour and 36 minutes. Ground controllers then powered up the device, ran diagnostics and updated software on the exter [...]
Astronomers using NASA's Hubble Space Telescope have applied a new image processing technique to obtain near-infrared scattered light photos of five disks observed around young stars in the Mikulski Archive for Space Telescopes database. These disks are telltale evidence for newly formed planets.
If astronomers initially miss something in their review of data, they can make new discoveries by revisiting earlier data with new image processing techniques, thanks to the wealth of information sto [...]
On April 24, 1990, the Hubble Space Telescope was launched aboard Space Shuttle Discovery on the STS-31 mission. The mission featured the deployment of Hubble, the first of NASA's Great Observatories to reach orbit. STS-31 was the tenth launch of the shuttle Discovery. On board were astronauts Charles F. Bolden (pilot, now NASA Administrator), Steven A. Hawley (mission specialist), Loren J. Shriver (commander), Bruce McCandless (mission specialist) and Kathryn D. Sullivan (mission specialist, no [...]
MOSCOW – Russia is set to develop its space cooperation with India and China, the head of the Russian space agency Roscosmos Oleg Ostapenko said on Thursday.
“Recently, we received an invitation from Japan to discuss an array of questions,” he added.
The announcement was made amid threats of Russia’s western partners to freeze or cut cooperation with Russia amid tensions over Ukraine and Crimea secession. NASA threatened to cut space ties with Russia, but Roscosmos has yet received [...]
The team designing the parachute system for NASA’s Orion spacecraft has demonstrated almost every parachute failure they could imagine. But on April 23, they tested how the system would perform if the failure wasn’t in the parachutes.
Orion is the safest spacecraft ever built to carry humans, and its Launch Abort System can take a good deal of the credit for that distinction. In an emergency on the launch pad or during the early stages of ascent, it can activate in milliseconds to pull th [...]
Earth's annual Lyrid meteor shower peaked before dawn on April 22nd, as our fair planet plowed through dust from the tail of long-period comet Thatcher. Even in the dry and dark Atacama desert along Chile's Pacific coast, light from a last quarter Moon made the night sky bright, washing out fainter meteor streaks.
But brighter Lyrid meteors still put on a show. Captured in this composited earth-and-sky view recorded during early morning hours, the meteors stream away from the shower's radian [...]
A test flight later this week will challenge a set of sensors to map out a 65-yard square of boulder-sized hazards and pick out a safe place to land.
Mounted to an uncrewed prototype lander called Morpheus that flies autonomously several hundred feet above the ground, the sensor system will have 10 seconds to do its work: six seconds really, as it will take four seconds to map the area before choosing a landing site.
The good news for the team of about 45 engineers who have been working [...]
NASA Astronauts Steve Swanson and Rick Mastracchio have completed a short spacewalk to replace a failed Multiplexer/Demultiplexer (MDM) back up computer. They began the re-pressurization of the Quest airlock at 11:32 a.m. EDT signifying the excursion’s end time.
The backup computer failed April 11 after a routine health check by the Mission Control team in Houston. While the primary computer continues operating flawlessly NASA managers ordered Wednesday’s spacewalk repair to ensure redund [...]
