| Posted: 14 Sep 2011 02:17 PM PDT The Mars rover Opportunity, which was designed to operate for three months and to rove less than a mile, has now journeyed more than seven years crossing more than 21 miles. Today, it is poised at the edge of a heavily eroded impact basin, the possible location of clay minerals formed in low-acid wet conditions on the red planet.  |
| Chemists help astronauts make sure their drinking water is clean Posted: 14 Sep 2011 02:17 PM PDT Researchers have developed chemistry and procedures that astronauts can use to test the quality of their drinking water at the International Space Station. The testing technology is now considered operational hardware at the space station. Astronauts will begin using refinements to the tests in late September.  |
| Posted: 14 Sep 2011 10:13 AM PDT Astronomers have shown how the Milky Way galaxy's iconic spiral arms form, according to new research. A dwarf galaxy named Sagittarius loaded with dark matter has careened twice through our much larger home galaxy in the past two billion years, according to telescope data and detailed simulations, and is lined up to do it again. As the galaxies collide, the force of the impact sends stars streaming from both in long loops.  |
| Shake, rattle and … power up? New device generates energy from small vibrations Posted: 14 Sep 2011 09:26 AM PDT Today's wireless-sensor networks can do everything from supervising factory machinery to tracking environmental pollution to measuring the movement of buildings and bridges. Working together, distributed sensors can monitor activity along an oil pipeline or throughout a forest, keeping track of multiple variables at a time. While uses for wireless sensors are seemingly endless, there is one limiting factor to the technology -- power. A new tiny energy harvester picks up a wider range of vibrations than current designs, and is able to generate 100 times the power of devices of similar size.  |
| New technology for recovering valuable minerals from waste rock Posted: 14 Sep 2011 08:58 AM PDT Researchers report discovery of a completely new technology for more efficiently separating gold, silver, copper, and other valuable materials from rock and ore. The process uses nanoparticles to latch onto those materials and attach them to air bubbles in a flotation machine.  |
| Posted: 14 Sep 2011 07:19 AM PDT NASA has selected the design of a new Space Launch System that will take the agency's astronauts farther into space than ever before, create high-quality jobs here at home, and provide the cornerstone for America's future human space exploration efforts. This new heavy-lift rocket-in combination with a crew capsule already under development, increased support for the commercialization of astronaut travel to low Earth orbit, an extension of activities on the International Space Station until at least 2020.  |
