The digital infrared sensor installed on the ESA’s Proba-V satellite is being adapted for use back home. While it’s currently being used to provide fresh pictures of the entirety of Earth’s flora every two days, its creators believe it’s well suited to less exotic applications, such as scanning for skin diseases and spotting defects in production lines.  Read More

Getting to Earth from the International Space Station (ISS) by jumping out of an airlock with a parachute may seem daft, but a group of students are trying just that with a CubeSat. According to NASA, TechEdSat-4, which was jettisoned from the space station on March 3, has reached its designated orbit, where it will use a parachute-like "exo-brake" to slow it down enough to safely re-enter the Earth's atmosphere.  Read More

A US Air Force weather satellite exploded in Earth orbit on February 3, scattering debris along its path. In a report by Space.com, Air Force and space officials indicated the breakup of Defense Meteorological Satellite Program Flight 13 (DMSP-F13) was due to a malfunction of its battery system rather than a collision with a foreign body. Meanwhile, The European Space Agency (ESA) has released an assessment of the hazard posed by the debris.  Read More

The launch of two new communications satellites may not seem like news these days, but it is when they're the first satellites with all-electric propulsion. Boeing announced that the two 702SP small platform satellites, called ABS-3A and EUTELSAT 115 West B, that launched on Sunday evening are sending back signals to mission control as they power towards geosynchronous orbit under ion drive.  Read More

The CubeSats would hitch a ride with ESA’s Asteroid Impact Mission (Image:ESA/APL)

CubeSats offer a way to get into space on the cheap. They're compact, inexpensive, and they can piggyback on larger launch payloads to get into orbit. The trouble is, this piggybacking is often like trying to hitchhike cross country on a ride that only goes to the edge of town. The European Space Agency is widening the scope a little by opening a competition for CubeSats to ride into deep space on its Asteroid Impact Mission (AIM).  Read More

NASA mission controllers have successfully deployed the Soil Moisture Active Passive (SMAP) observatory’s reflector antenna, in what is an important step along the road towards the satellite becoming fully operational.  Read More

Satellite and GIS data is helping developing countries better manage limited resources in ...

Each year, hundreds of millions of people in developing countries are affected by parasitic diseases. One of the most common is malaria, which kills more than a million people annually, mostly children under five years of age. Scientists are using satellite data combined with local health information uploaded into geographical information systems (GIS) to help developing countries better manage limited resources and target interventions in the fight against malaria and other deadly parasitic diseases.  Read More

February 11 marked the two-year anniversary of the launch of NASA’s Landsat 8 satellite, an event that signaled the continuation of an Earth observation project that began in the early 1970s. To celebrate the occasion, the team has released a vast composite image that stretches unbroken from Sweden to British Columbia.  Read More

Back in October 2013, two NASA probes were in the perfect position to observe a solar wave as it hit Earth’s magnetic field, gathering data on the event. That data has now been analyzed by teams of scientists at MIT’s Haystack Observatory and the University of Colorado, revealing the process by which harmful, high-speed particles are generated in Earth’s radiation belts.  Read More

Recently, DARPA unveiled its ALASA system for launching satellites from fighter planes. Now NASA is upping the ante with its Towed Glider Air-Launch System (TGALS), which is designed to launch satellites from a twin-fuselage towed glider. Under development by NASA's Armstrong Flight Research Center at Edwards Air Force Base, California, it's designed as an economical method for putting spacecraft into low-Earth orbit with the first test flight of a scale prototype having already been conducted.  Read More
