NASA's long-lived Mars Reconnaissance Orbiter put itself into a precautionary safe standby mode March 9 after an unscheduled swap from one main computer to another. The mission's ground team has begun restoring the spacecraft to full operations.
"The spacecraft is healthy, in communication and fully powered," said Mars Reconnaissance Orbiter Project Manager Dan Johnston of NASA's Jet Propulsion Laboratory, Pasadena, Calif. "We have stepped up the communication data rate, and we plan to have [...]
Pasadena, CA— Some galaxies grew up in a hurry. Most of the galaxies that have been observed from the early days of the universe were young and actively forming stars. Now, an international team of astronomers, including Carnegie's Eric Persson and Andy Monson, have discovered galaxies that were already mature and massive in the early days.
Fifteen mature galaxies were found at a record-breaking average distance of 12 billion light years, when the universe was just 1.6 billion years old. T [...]
In a press conference today, NASA’s Marshall Space Flight Center and Sierra Nevada Corporation (SNC) announced an expanded collaboration to advance the planning and development of potential science research during future Dream Chaser spacecraft missions.
Under a new annex to a current Space Act Agreement, Marshall’s Mission Operations Laboratory will provide technical expertise to SNC for planning the integration of scientific payloads on its Dream Chaser spacecraft under their Advanced [...]
Expedition 39 officially began Monday at 8:02 p.m. EDT when Soyuz Commander Oleg Kotov and Flight Engineers Mike Hopkins and Sergey Ryazanskiy undocked from the International Space Station.
The trio was inside the Soyuz TMA-10 spacecraft when it gently backed away from the Poisk module for its return to Earth. They landed in frigid conditions in Kazakhstan at 11:24 p.m. and were assisted by a smaller recovery team due to snowy, windy conditions at the landing site.
Packed inside their r [...]
Soyuz Commander Oleg Kotov and Expedition 38 Flight Engineers Mike Hopkins and Sergey Ryazanskiy landed in Kazakhstan at 11:24 p.m. EDT. They landed inside the Soyuz TMA-10 spacecraft ending their mission after five-and-a-half months aboard the International Space Station. The trio undocked from the Poisk module at 8:02 p.m. EDT.
Staying behind are new Expedition 39 Commander Koichi Wakata and Flight Engineers Rick Mastracchio and Mikhail Tyurin. The crew members arrived at the station’s Ra [...]
In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. The above image taken in January using multiple exposures and very specific colors of Sulfur (shaded red), Hydrogen (green), and Oxygen (blue), captures the central region in tremendous detail.
A hot wind of particles streams away from the cluster stars and contributes to an already complex menagerie of gas and du [...]
