The European Space Agency (ESA) has successfully linked up the Sentinel-1A and Alphasat satellites via laser, transmitting data across almost 36,000 km (about 22,400 miles) of space. The link allows for the delivery of data to Earth in near real time, and will be used for a wide range of applications including the timely monitoring of natural disasters.  Read More

Researchers from the University of Carlos III in Madrid have created a new frictionless tr...

A new transmission device that uses magnetic levitation to almost completely eliminate friction and wear has been developed as part of the MAGDRIVE research project, a collaboration of seven European nations we looked at back in 2010. The creation of the unit entailed the development of a magnetic gear reducer and corresponding frictionless magnetic axles. Aimed primarily for use in spacecraft due to its extended mechanical life, the system is also adaptable for use in automobiles, railways, and aircraft.  Read More

The European Space Agency's Venus Express unmanned probe is being put through a series of maneuvers in hopes that its remaining fuel can push it into a higher orbit. If successful, the orbit change will give the spacecraft a bit more life before it plunges into the Venusian atmosphere it was sent to investigate.  Read More

The European Space Agency (ESA) has released an image mosaic taken by the Rosetta mothership showing the Philae lander’s November 12 touchdown on comet 67P/Churyumov–Gerasimenko. The composite image shows the unmanned spacecraft making its approach to the surface of 67/P and its first rebound after its anchoring harpoons failed to deploy, along with timestamps in GMT (lander time) and images contrasting the touch sites before and after landing.  Read More

ESA is set to send a 3D printer up to the International Space Station (ISS) for a preliminary round of orbital testing in the first half of next year. The Portable On-Board Printer (POP3D), was designed and manufactured in Italy and will be one of the focusses of ESA astronaut Samantha Cristoforetti's Futura mission. The results of the study will be instrumental in informing us on the potential uses of 3D printing in microgravity.  Read More

After its historic landing on a comet, the Philae spacecraft has gone silent. Trapped on its side in a shadowed hole, the unmanned European Space Agency lander was unable to receive enough sunlight to recharge its battery and contact was lost today at 00:36 GMT when power levels dropped below critical.  Read More

During Wednesday’s historic landing on comet 67P/Churyumov-Gerasimenko, the European Space Agency's Philae lander suffered a setback that may cut its mission short. Due to equipment malfunctions, the unmanned, washing machine-sized lander failed to secure itself to the surface of the comet. In the 1/100,000 gravity, Philae bounced back into space twice, eventually landing in a hole about a kilometer (0.6 mi) from its designated landing area, where its batteries may not be able to charge properly.  Read More

History was made today as a spacecraft the size of a fridge executed the first successful landing on a comet. The European Space Agency (ESA) confirms that at about 16:00 GMT the unmanned Philae space probe touched down on the surface of comet 67P/Churyumov-Gerasimenko at the landing site known as Agilkia. The comet and spacecraft are 510 milion km (310 million miles) from Earth, so the news of the landing took 28 minutes and 20 seconds to reach mission control in Darmstadt, Germany.  Read More

On the eve of the planned first landing on comet 67P/Churyumov-Gerasimenko, the European Space Agency (ESA) announced that the unmanned Rosetta orbiter carrying the Philae lander has recorded a "song" emanating from the comet. The electromagnetic melody was detected by the probe’s Rosetta Plasma Consortium, which is a suite of five instruments used to study 67P.  Read More

The European Space Agency (ESA) has given the green light for its unmanned Philae probe to attempt the historic first landing on a comet. At a press conference at at the European Space Operations Centre in Darmstadt, Germany, representatives of ESA and the German Aerospace Centre told the media that both the Rosetta mothership and the Philae lander are in excellent shape for Wednesday morning’s (GMT) planned separation and landing on comet 67P/Churyumov-Gerasimenko.  Read More
