| NASA Ames to launch science experiments to space station on SpaceX rocket Posted: 18 Sep 2014 09:28 AM PDT NASA's Ames Research Center in Moffett Field, California, will launch four life science experiments to the International Space Station aboard NASA's next commercial cargo resupply flight of the SpaceX Dragon spacecraft. The research missions include a microbiology study of yeast, a fruit fly study designed and built by students, a plant biology investigation and the maiden voyage of NASA's new rodent research system. |
| Everything in moderation: Micro-8 to study regulating pathogens in space Posted: 18 Sep 2014 09:26 AM PDT Candida albicans, an opportunistic yeast pathogen and model organism for research, is common and usually doesn't damage our healthy personal ecosystem. However, when our immune system is stressed on Earth or in space, such as during long-duration space travel, C. albicans can grow out of control and potentially cause infections. Scientists want to address controlling these outbreaks with the next round of cellular growth experiments on the International Space Station -- Micro-8. |
| Dawn spacecraft operating normally after safe mode triggered Posted: 18 Sep 2014 09:24 AM PDT The Dawn spacecraft has resumed normal ion thrusting after the thrusting unexpectedly stopped and the spacecraft entered safe mode on September 11. That anomaly occurred shortly before a planned communication with NASA's Deep Space Network that morning. The spacecraft was not performing any special activities at the time. |
| NASA Mars spacecraft ready for Sept. 21 orbit insertion Posted: 18 Sep 2014 09:22 AM PDT NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled Sept. 21 insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles (711 million kilometers). |
| Pulse of a dead star powers intense gamma rays Posted: 18 Sep 2014 09:08 AM PDT NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, is helping to untangle the mystery of what powers high-energy gamma rays emanating from supernova. The observatory's high-energy X-ray eyes were able to peer into a particular site of powerful gamma rays and confirm the source: A spinning, dead star called a pulsar. |
| NASA's wind-watching ISS-RapidScat ready for launch Posted: 18 Sep 2014 09:04 AM PDT The fourth SpaceX cargo mission to the International Space Station (ISS) under NASA's Commercial Resupply Services contract, carrying the ISS-RapidScat scatterometer instrument designed and built by NASA's Jet Propulsion Laboratory, Pasadena, California, is scheduled to launch Saturday, Sept. 20, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. The one-day adjustment in the launch date was made to accommodate preparations of the SpaceX Falcon 9 rocket and was coordinated with the station's partners and managers. |
| Comet landing mission: 'J' marks the spot for Rosetta's lander Posted: 18 Sep 2014 09:00 AM PDT The European Space Agency's Rosetta's lander, Philae, will target Site J, an intriguing region on comet 67P/Churyumov-Gerasimenko that offers unique scientific potential, with hints of activity nearby, and minimum risk to the lander compared to the other candidate sites. The 220-pound (100-kilogram) lander is scheduled to reach the surface on November 11, where it will perform in-depth measurements to characterize the nucleus. Rosetta is an international mission spearheaded by the European Space Agency with support and instruments provided by NASA. |
| NASA releases IRIS footage of X-class flare Posted: 17 Sep 2014 02:32 PM PDT On Sept. 10, 2014, NASA's newest solar observatory, the Interface Region Imaging Spectrograph, or IRIS, joined other telescopes to witness an X-class flare -- an example of one of the strongest solar flares -- on the sun. |
| Space: The final frontier ... open to the public Posted: 17 Sep 2014 02:32 PM PDT Historically, spaceflight has been reserved for the very healthy. Astronauts are selected for their ability to meet the highest physical standards to prepare them for any unknown challenges. However, with the advent of commercial spaceflight, average people can now fly. The aerospace medicine community has had little information about what medical conditions should be considered particularly risky in the spaceflight environment, as most medical conditions have never been studied for risk in space -- until now. |
