Engineers at NASA's Marshall Space Flight Center in Huntsville, Ala., recently flipped an adapter -- no easy feat when you're talking about 1,000 pounds of aluminum -- furthering progress toward Exploration Flight Test (EFT)-1 in 2014 and providing early experience for Space Launch System (SLS) hardware ahead of the rocket's first flight in 2017. The flip is an important step in finishing the machining work on the adapter, which will attach NASA's Orion spacecraft to a United Launch Alliance (UL [...]
MOSCOW - Russia’s first light-class modification Angara 1.2PP carrier rocket is ready for its maiden launch, its manufacturer Khrunichev Center said on Wednesday.
The first Angara will be sent to the Plesetsk space center in northern Russia later this month, the manufacturer said in a statement, but did not give a precise launch date.
Meanwhile, the first heavy-class Angara-A5 has been completed and will soon be presented to the public, a Khrunichev spokesman said.
The project is bein [...]
Following the apparent failure of reaction wheel 4 on May 11, 2013, engineers were successful at transitioning the spacecraft from a Thruster-Controlled Safe Mode to Point Rest State at approximately 3:30 p.m. PDT on Wednesday, May 15, 2013. The spacecraft has remained safe and stable in this attitude and is no longer considered to be in a critical situation.
As part of a normal spacecraft response to a pointing error, redundant electronics were automatically powered off to isolate them as a [...]
Commander Pavel Vinogradov and Flight Engineer Alexander Misurkin are installing a new treadmill in the Zvezda service module. Flight Engineer Chris Cassidy is working science and maintenance on the U.S. side of the International Space Station. The trio also conducted an emergency drill and held a conference with the ground to review the results.
On Monday, Vinogradov and Misurkin removed and disassembled an old treadmill in Zvezda. A new treadmill was delivered on the ISS Progress 51 that d [...]
This Hubble image shows the galaxy cluster Abell S1077. Galaxy clusters are large groupings of galaxies, each of them including millions of stars. They are the largest existing structures in the Universe to be held together by their gravity.
The amount of matter condensed in such groupings is so high that their gravity is enough to warp the fabric of spacetime, distorting the path that light takes when it travels through the cluster. In some cases, this phenomenon produces an effect somewhat [...]
Pulsars have a number of unusual qualities. Like zombies, they shine even though they’re technically dead, and they rotate rapidly, emitting powerful and regular beams of radiation that are seen as flashes of light, blinking on and off at intervals from seconds to milliseconds. A NASA team has built a first-of-a-kind testbed that simulates these distinctive pulsations.
The pulsar-on-a-table, known as the Goddard X-ray Navigation Laboratory Testbed, was built to test and validate a next-gen [...]
The Expedition 36 trio aboard the International Space Station started its work week taking apart a treadmill and working on science hardware. Another trio is in Kazakhstan counting down to a May 28 launch aboard a Soyuz rocket to join their orbiting crewmates.
Commander Pavel Vinogradov was joined by Flight Engineer Alexander Misurkin spending most of Monday disassembling a treadmill in the Zvezda service module. It will be replaced by a newer treadmill that was delivered April 26 inside the [...]
PASADENA, Calif. - NASA's Mars rover Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called "Cumberland."
Plans call for delivering portions of the sample in coming days to laboratory instruments inside the rover. This is only the second time that a sample has been collected from inside a rock on Mars. The first was Curiosity's drilling at a target called "John Klein" three months ago. Cumberland resembles John Klein and lies about nin [...]
