Between 23 and 30 November the operations team at ESOC will conduct manoeuvres to raise the pericentre of the Venus Express (VEX) orbit again, in an effort to keep the spacecraft in productive orbit around Venus.
These manoeuvres could be the last for VEX due to low propellant levels, but all being well, VEX will continue its valuable scientific observations into 2015. The question is: how much longer can the spacecraft operate?
Venus Express has been in a reduced science phase since its ...
Airbus Defence and Space has been awarded a contract for system evolution and maintenance of the US Air Force’s five Eagle Vision stations until 2019. Systems evolutions are related to foot print reduction (transit cases versus shelter), smaller antenna dishes and integration of new satellites. The sustainment of the system covers 24/7 support, failure corrections with workaround solutions, spares management, preventive maintenance, training and support during deployments.
Two donuts of seething radiation that surround Earth, called the Van Allen radiation belts, have been found to contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth.
The Van Allen belts are a collection of charged particles, gathered in place by Earth’s magnetic field. They can wax and wane in response to incoming energy from the sun, sometimes swelling up enough to expose satellites in low-Earth orbit to damaging radiation. Th...

The upper passenger for Arianespace's dual-satellite launch from French Guiana next week has been encapsulated in its protective payload fairing, preparing the DIRECTV-14 relay platform for its integration on Ariane 5.
During activity in the Spaceport's Final Assembly Building for Ariane 5, DIRECTV-14 was mounted on the launcher's SYLDA dispenser unit, followed by the lowering of a large ogive-shaped payload fairing over the combined unit - creating the mission's "up...
The fifth SpaceX cargo mission to the International Space Station (ISS) under NASA's Commercial Resupply Services contract is scheduled to launch Tuesday, Dec. 16, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. NASA Television coverage of the launch begins at 1:15 p.m. EST.
The company's Falcon 9 rocket will lift off at 2:31 p.m., carrying its Dragon cargo spacecraft. It is loaded with more than 3,700 pounds of scientific experiments, technology demonstrations an...
To a casual stargazer, most stars look the same. Some may be brighter, others dimmer, but for the most part, they are all variations on the same theme. All stars are so far away that we see them only as pinpoints of light.
NASA is webcasting a number of events this week leading up to Thursday's (Dec. 4) historic first test flight of the agency's Orion space capsule. Watch live here, beginning Tuesday (Dec. 2) at 12 p.m. EST (1700 GMT).
Oberwerk's Ultra 15x70 are a wonderful balance of size, weight and optical performance. Space.com's Editors chose them over all others, except one. Medium binoculars can be mounted or handheld if braced.
Celestron's Cometron 7 x 50 offers remarkable views and excellent value for a low price. Space.com's editors chose them over all others, except one. These small binoculars are easy to carry and superb for kids.
Researchers have measured the distance to the active galaxy NGC 4151, dubbed "The Eye of Sauron," with unprecedented precision. This calculation enabled them to determine that NGC 4151's central black hole is 40 percent more massive than thought.
Can you tell me how to get, how to get to... Mars? Elmo, Cookie Monster and the other muppets from "Sesame Street" have joined forces with NASA to count down to the first launch of the Orion spacecraft.
The milestone marks a key step toward a future in which voyaging spaceships print out their own spare parts on the go and colonists on other worlds make what they need from the dirt beneath their boots, 3D printing advocates say.
