GPM satellite to usher in a new era of weather observation

NASA is set to launch a new satellite designed to take detailed, near real-time measurements of rain and snowfall on a global scale whilst mapping the interior of storm systems. The Core Observatory of the Global Precipitation Measurement (GPM) has been in development since 2005 and is a collaboration project between NASA and the Japanese Space Agency (JAXA). The satellite is due to be launched on the Japanese manufactured H-IIA delivery vehicle from the Tanegashima Space Centre, Tanegashima Island, Japan, on February 27. Read More

Cost-effective laser-based asteroid defense system pitched to NASA

Last year, the University of Strathclyde in Glasgow put forward the idea of using fleets of laser-toting satellites to deflect potentially dangerous objects away from Earth. Now, Dr. Richard Fork, principal investigator for the Laser Science and Engineering Laboratory at the University of Alabama and his team have refined the idea, saying that it’s not only feasible, but could handle anything up to the size of a comet.
