ESA's Sentinel-2A satellite arrives in French Guiana ahead of launch

By - April 27, 2015 2 Pictures
ESA's Sentinel-2A satellite has arrived safely in French Guiana, ahead of its June 12 launch atop a Vega rocket. It was carried in the belly of an enormous Russian-made Antonov cargo plane, and protected within a specially-constructed air conditioned habitat. Once operational, the satellite will represent a cornerstone of the agency's Copernicus program, which is striving to revolutionize how we observe and understand our environment, and how we may be able to tackle the detrimental effects of climate change.

ESA tests the potential of grabbing derelict satellites using a simple net

By - March 30, 2015 2 Pictures
The ESA has been testing the possibility of using one of mankind's earliest inventions to cope with one of its newest challenges, by testing a concept that would allow satellites to net and de-orbit space debris in a safe and controlled manner. Space debris is an ever-increasing problem, and agencies around the world are starting to take steps to preserve the low-Earth orbit environment vital for a sustainable space industry. Read More

Construction begins on Space Fence radar system

By - March 24, 2015 3 Pictures
Ground was broken at the future six-acre (2.4-hectare) site of the new Space Fence radar system in a special ceremony last month on Kwajalein Atoll in the Marshall Islands. The ceremony marked the official start of construction of the system that will replace the Air Force Space Surveillance System (AFSSS) in tracking objects in orbit, including commercial and military satellites and debris from collisions.

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

By - March 11, 2015 7 Pictures
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

By - March 8, 2015 3 Pictures
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

NASA seeks to understand vision changes due to microgravity

By - March 6, 2015 2 Pictures
Having evolved under the pressure of Earth's gravity, it isn't surprising that our bodies experience adverse physiological affects after long periods in low-Earth orbit. NASA hopes that a new experiment, the Fluid Shifts investigation, set to launch to the ISS later this year, will shed light on the causes of vision loss and deformation of the structure to the eye often suffered by astronauts over the course of a stay aboard the ISS.
