Radiation Pattern Measurements Of The Nasa Mars Science Laboratory UHF Entry Antenna Using A Spherical Near-Field Range
2013-08-29 12:43:47| rfglobalnet News Articles
Measurements of a conical micro-strip Wraparound™ antenna array mounted on a portion of the entry vehicle for NASA’s Mars Science Laboratory mission were completed at Nearfield Systems, Inc.’s new spherical near-field range facility. The Wraparound™ antenna, designed and manufactured by Haigh-Farr, Inc., provides nearly full spherical coverage and operates in the UHF frequency band for telecommunications to orbiting assets at Mars. A summary of the measurements techniques and results are presented, along with a comparison of the measured and calculated patterns. By Paula R. Brown, David Farr, John Demas, and Jesus A. Aguilar

NASA is going on the offensive with increased viability of its asteroid capture concept. However, Congress may not actually approve the proposed plan.
NASA Study Finds Connection Between Population & Pollution
2013-08-20 22:04:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: While previous research has linked employment or innovation statistics to urban population density, a new study from NASA scientists has made a connection between pollution and the number of people living in a city. Using satellite observations, the NASA team was able to calculate air pollution's dependence on population for cities in the United States, Europe, China and India. According to the report, which was published in the journal Environmental Science & Technology, pollution has a direct...

NASA discusses its warp drive research, prepares to create a warp bubble in the lab
2013-08-20 19:29:53| Extremetech
Late last year, it emerged that a small team of NASA researchers were working on warp drive technology in the lab. Led by Harold "Sonny" White, the team devised a variation of the Alcubierre warp drive that could almost be feasibly produced -- if we can work out how to produce and store antimatter. Now, White is ready to discuss some other facets of his warp drive, such as the energy requirements, what a spacecraft with a warp drive would look like, and what it would be like to travel at warp speed.
