DARPA seeks to develop command and control center for outer space

The area in the outer reaches of the Earth's atmosphere is a swarm of manmade objects, moving at tens of thousands of miles per hour and traversing a region hundreds of thousands of times larger than all of Earth's oceans combined. This complicates the operation of satellites for military use. DARPA has just announced its plans to come to grips with this chaotic region with the launch of a project aimed at revolutionizing the US military's command and control capabilities in space.Read More

Testing the world's blackest material in orbit

A cutting edge light retardant coating designed to reduce the interference to the delicate optical equipment mounted on space probes is being put through its paces aboard the Kent Ridge 1 satellite, which launched into low-Earth orbit (LEO) in Dec. 2015. Known as Vantablack S-VIS, it is hoped that the high performance and versatility of the material will allow for the design of lighter, more compact satellite hardware.Read More

How Earth's magnetic field is changing

The European Space Agency (ESA) launched its trio of Earth-facing satellites – the Swarm satellites – more than two years ago. Since then, the three probes have been tirelessly making measurements of the Earth's magnetic field, mapping it out in detail. Now, that data has been used in a new study of how the magnetic field has changed over recent years, with the results echoing what's happening at the planet's core. Read More

DARPA's satellite repair robot makes house calls

There are over 400 geosynchronous satellites orbiting 22,000 mi (36,000 km) above the Earth. They are a vital part of global communications and represent billions of dollars in investments, but once they break down or run out of fuel, they're so much tin foil. DARPA has released a video outlining the agency's vision of a mobile robotic servicing system designed to rendezvous with and repair ailing telecommunications satellites.Read More

ESA puts 3D-printed satellite antenna to the test

We can't print entire satellites yet, but the 3D printing of major components is moving forward with ESA unveiling a prototype 3D-printed radio antenna. Currently undergoing testing at ESA's Compact Antenna Test Facility in Noordwijk, the Netherlands, it's the space agency's first 3D-printed dual-reflector antenna incorporating a corrugated feed horn and two reflectors.Read More
