| NASA instruments on Rosetta start comet science Posted: 11 Jun 2014 07:07 AM PDT Three NASA science instruments aboard the European Space Agency's (ESA) Rosetta spacecraft, which is set to become the first to orbit a comet and land a probe on its nucleus, are beginning observations and sending science data back to Earth. |
| Mercury passes in front of the sun, as seen from Mars Posted: 11 Jun 2014 07:00 AM PDT NASA's Curiosity Mars rover has imaged the planet Mercury passing in front of the sun, visible as a faint darkening that moves across the face of the sun. |
| NASA announces two upcoming undersea missions Posted: 11 Jun 2014 06:59 AM PDT NASA is returning to the bottom of the ocean. Twice this summer, aquanauts participating in the NASA Extreme Environment Mission Operations (NEEMO) will conduct activities on the ocean floor that will inform future International Space Station and exploration activities. These studies provide information that correlates directly to life aboard the space station, where crew members must frequently perform critical tasks that present constraining factors similar to those experienced in an undersea environment. |
| NASA's Orion spacecraft stacks up for first flight Posted: 11 Jun 2014 06:57 AM PDT With just six months until its first trip to space, NASA's Orion spacecraft continues taking shape at the agency's Kennedy Space Center in Florida. Engineers began stacking the crew module on top of the completed service module Monday, the first step in moving the three primary Orion elements -crew module, service module and launch abort system -- into the correct configuration for launch. |
| Map of universe questioned: Dwarf galaxies don't fit standard model Posted: 11 Jun 2014 06:36 AM PDT Dwarf galaxies that orbit the Milky Way and the Andromeda galaxies defy the accepted model of galaxy formation, and recent attempts to wedge them into the model are flawed, reports an international team of astrophysicists. A new study pokes holes in the current understanding of galaxy formation and questions the accepted model of the origin and evolution of the universe. |
