When Sentinel-1 is placed in orbit around Earth in a few weeks, it has to perform a complicated dance routine to unfold its large solar wings and radar antenna. Engineers have recently been making sure the moves are well rehearsed.
The in-orbit validation of Galileo has been achieved: Europe now has the operational nucleus of its own satellite navigation constellation in place – the world’s first civil-owned and operated satnav system. In 2011 and 2012 the first four satellites were launched into orbit. Four is the minimum number needed to perform navigation fixes.
Environmental research and weather forecasting are about to get a significant technology boost as NASA and the Japan Aerospace Exploration Agency (JAXA) prepare to launch a new satellite in February.
Phonesat STRaND-1 - a nanosatellite carrying a Google Nexus One smartphone - was launched into orbit from India earlier this week.
A British team is putting the finishing touches to the first-ever satellite to be controlled entirely by a mobile phone.
NASA's ability to track satellites and orbiting spacecraft is about to get a big boost, following the launch last night of a next-generation communication satellite.
Iran's successfully given a live monkey a round trip into space, the country's Al-Alam television channel reports.
NASA is conducting its first round of tests to develop robots capable of repairing and refueling satellites in space.
The US Geological Survey is to decomission Landsat 5 - the longest-operating Earth observing satellite mission ever.
It could be possible to get advance warning of volcanic eruptions by observing them from space.
Physicists at the University of Vienna and the Austrian Academy of Sciences recently managed to achieve quantum teleportation over a record distance.
Putting a satellite into orbit is a rather expensive endeavor that typically costs millions of dollars.
Scientists have been able to count the number of emperor penguins in Antarctica by using satellite mapping technology - and there's twice as many as previously thought, they say.
While glaciers globally are shedding billions of tons of ice each year, the Himalayas aren't, a study shows.
Iran says it's launched an observation satellite, claiming it will be used to collect weather data.
When scientists discovered two great swaths of radiation encircling Earth in the 1950s, it spawned exaggerated fears about "killer electrons" and space radiation effects.
The European Space Agency has launched the first two Galileo satellites which will give Europe its own satellite navigation system for the first time.
Well, you may have been lucky last time, but there's another satellite heading back to Earth, and this time it's much more likely that it'll land on your head.
Put on your hard hats, everybody: NASA's warning that a defunct satellite is set to hit the earth sometime in the next six weeks.
A recently published report warns that space junk poses a clear and present danger to orbiting satellites and the International Space Station (ISS).
