NASA tests parachute-like space brakes to de-orbit satellites

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.

US satellite explodes and ESA assesses risk

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

First satellites with all-electric propulsion call home

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

ESA offers CubeSats a deep space ride on asteroid mission

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

Satellites and GIS help developing countries target deadly parasites

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.

MIT scientists analyze harmful electron-producing solar shockwave

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
