This month, the University of Helsinki and the European Space Agency (ESA) will test a new space tether that has less chance of snapping under the stresses of operating in orbit. Installed aboard Estonia’s ESTCube-1 cubesat, the new tether is scheduled to be launched with ESA’s Proba-V satellite atop a Vega rocket as part of an experiment in developing an electric solar sail.  Read More

The newest Landsat satellite has transmitted its first images back home (Image: NASA)

We haven't heard anything from NASA's Landsat Data Continuity Mission (LDCM) spacecraft since its launch in February, but the satellite is now ready to start sending its first images back home. The first batch of photos are part of a three-month testing period, and show the meeting of the Great Plains with the Front Ranges of the Rocky Mountains in Wyoming and Colorado. Viewed from space, it's already a pretty spectacular scene, but the images from the LDCM managed to enhance it even further.  Read More

S3's planned satellite-carrying shuttle, being carried itself on an Airbus A300

If you want to launch a satellite in the usual way – on top of a rocket – it will typically cost you at least US$50,000,000. Newly-inaugurated aerospace firm Swiss Space Systems (S3), however, claims that it will be able to put your small satellite into orbit for about 10.6 million bucks. Why so cheap? S3 is planning on flying satellites into space, using an airliner and an unmanned shuttle.  Read More

The five meter-long GOCE satellite has been found to have detected the 2011 Tohoku earthqu...

The European Space Agency’s Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite was launched on March 17, 2009, as the first of a series of Earth Explorer satellites. Its mission is to capture high-resolution gravity measurements and produce an accurate gravity map – or geoid – of Earth. To increase the resolution of its measurements, GOCE was put into an unusually low orbit, which has also helped it to become the first satellite to sense sound waves from an earthquake from space.  Read More

STRaND-1 having its solar panels atached

The world’s first space smartphone was launched into orbit today (Feb 25) atop an Indian Space Research Organisation PSLV rocket from the Satish Dhawan Space Centre in Sriharikota, India. It’s part of the systems of the STRaND-1 spacecraft, which was sent into a 785-kilometer (488-mi) Sun-synchronous orbit where it will carry out a series of technology demonstrations under the guidance of the Surrey Space Centre’s ground station at the University of Surrey, UK.  Read More

One of the BRITE nano-satellites, as it was being assembled in Toronto

At the Satish Dhawan Space Centre in Sriharikota, India this morning (Feb. 25), the smallest astronomical satellite ever built was launched into orbit aboard the Polar Satellite Launch Vehicle C20 rocket. In fact, it wasn’t just one satellite, but two – each of the twin BRIght Target Explorer (BRITE) spacecraft take the form of a cube that measures just 20 cm (7.8 inches) per side, and weighs in at under seven kilograms (15.4 lbs).  Read More

The new Landsat 8 will continue NASA's 40-year program (Photo: NASA)

NASA's Landsat Data Continuity Mission (LDCM) spacecraft was successfully placed in orbit earlier this week. The mission marks the continuation of the 40-year Landsat Earth-observation program, which aids in the study of dynamic and ongoing changes to the planet.  Read More

The STRaND-1 is a smartphone-based nanosat that is set to become the U.K.'s first CubeSat ...

The University of Surrey’s Surrey Space Centre (SSC) and Surrey Satellite Technology Limited (SSTL) are set to launch the world’s first smartphone-based satellite. Built around a Google Nexus One smartphone running on the Android operating system, the STRaND-1 (Surrey Training, Research and Nanosatellite Demonstrator) satellite will also be the U.K.’s first CubeSat to go into space.  Read More

Artist's concept of a Phoenix tender in action

The Defense Advanced Research Projects Agency (DARPA) has released a new video showing the progress of its Phoenix project, which aims at salvaging parts from defunct communications satellites to build new ones. Based on a new class of nanosatellites and a robotic “tender,” its purpose is to use repurposed satellites to construct a new communications net for the military at low cost.  Read More

The Multifunction Tool uses its attached adapter to manipulate a plug located under the Am...

NASA and the Canadian Space Agency (CSA) have begun practicing satellite refueling in space on a test bed outside the International Space Station (ISS). In a series of tests that started on January 14 and are scheduled to continue until the 25th, the two space agencies are using the Robotic Refueling Module (RRM) and Canada’s Special Purpose Dexterous Manipulator, or Dextre, robot to carry out simulated refueling operations. The purpose of these tests is to develop refueling methods aimed at extending the life of satellites and reducing the amount of space debris orbiting the Earth.  Read More
