The US Air Force has announced that it is introducing a new "eSeries" classification for military air and space hardware, indicated by an "e" prefix", that has been digitally engineered and virtually tested before a physical example is ever built.

Rocket Lab made a successful return to service by launching a customer’s satellite into orbit earlier this week, but that wasn’t the only cause for celebration, with the team also deploying its own Photon satellite as part of the same flight.

Given how many satellites and bits of orbital debris are now orbiting the Earth, it's becoming increasingly important to keep track of where they all are. A new telescope system allows space agencies and other clients to do so – even in broad daylight.

NASA's Transiting Exoplanet Survey Satellite space telescope has now wrapped up the primary phase of its mission, completing an extensive survey of the starry sky that revealed 66 new exoplanets and thousands more candidates.

On 12 July 2017, one of the biggest icebergs ever seen broke off from the Antarctic mainland. Now on the third anniversary of the event, satellite data has shown that the berg has traveled over 1,000 km (620 mi) and managed to stay relatively intact

Researchers have demonstrated quantum entanglement on a small satellite orbiting Earth. The team developed a miniaturized device that produces pairs of photons that are inextricably linked, which could help launch a fast and secure quantum internet.

Turns out the Red Planet is a little more green than we thought. The ExoMars Trace Gas Orbiter (TGO) has detected a tinge of green in the atmosphere, making it the first time this aurora-like glow has been spotted around a planet other than Earth.

SpaceX has followed last week's historic launch by firing a further 60 high-speed internet satellites into orbit as part of its Starlink project, including one fitted out with an experimental sun visor designed to reduce the reflectivity.

Virgin Orbit has come up short on its first attempt to reach orbit today after the mission was terminated soon after ignition of its LauncherOne rocket, with the team now working through the data and gearing up for its next attempt.

A small asteroid came within a cosmic hairbreadth of the ring of communications satellites circling the Earth in geosynchronous orbit at an altitude of about 35,000 km this week, passing the nearest satellite at a distance of about 1,200 km.

A new paper has revealed that Greenland and the Antarctic have lost a staggering amount of mass from their ice sheets over the last 16 years thanks to climate change, and that the melting has contributed to sea level rise.

SpaceX has announced that it will mount a sun visor on each of its Starlink satellites and have them perform controlled maneuvers, to make them less visible to the public and astronomers making detailed observations of the night sky.
