Cassini probe's death dive to send data at just 27 kilobits per second

Space is nasty and sending data across 83 light-minutes of it isn't easy, so the Cassini probe's death dive into the clouds of Saturn will be an instruments-only affair undocumented by photographs. Cassini has surveyed Saturn since 2004 but is out of fuel, so will be crashed into Saturn instead of leaving it an an orbit that …

Ten spacecraft – from Venus Express to Voyager 2 – all tracked same solar flare

On October 14th, 2014, the Sun decided it was time for a coronal mass ejection, the irregular hiccups that see it belch out astounding quantities of magnetised plasma. And after careful analysis, we've now fingerprinted the plasma's passing using no fewer than ten spacecraft. The event and subsequent analysis are detailed in a …

NASA delivers CREAM-y load to ISS to improve cosmic ray detection

Hitching a ride on SpaceX's 12th commercial resupply mission to the International Space Station is NASA's latest tech for studying the origins of cosmic rays, the high-energy particles that bombard Earth from deep space. Victor Hess, an Austrian physicist, is credited with discovering cosmic rays during a balloon flight in …

Cancel the farewell party. Get back to work. That asteroid isn't going to hit Earth in October

The European Space Agency has confirmed there is no danger of asteroid 2012 TC4 hitting Earth in October, despite what some panicky YouTube videos might tell you. The rock was spotted five years ago when it whizzed past Earth, missing us by 94,800 kilometres (58,900 miles). Last month NASA eggheads reckoned the asteroid may …

ESA trying to 'bake, rattle and roll' gravity wave space probe

The European Space Agency is giving the LISA Pathfinder probe what it calls the “Bake, rattle and roll” treatment in the hope it teaches us how to make its successors even better. As the name suggests, LISA Pathfinder is a test mission for the planned three-vessel LISA space observatory, which will be positioned in a …

Skynet? More like Night-sky-net. AI hunts for Milky Way's turbo stars

An artificial neural network has detected rare super-fast stars zipping through the Milky Way – by crunching piles of data collected by the European Space Agency’s Gaia probe. Hypervelocity stars (HVSes) are flung from the Way's Galactic Center and can reach speeds faster than our galaxy's escape velocity. Only 20 unbound …

Europe to upgrade its continental GPS

The European Space Agency has announced plans to upgrade the European Geostationary Navigation Overlay Service (EGNOS). EGNOS uses three geostationary satellites and 40 ground stations to verify GPS signals. Output is deemed accurate to within three metres, rather less than the 17 metres assumed for unrefined GPS. EGNOS …

Schiaparelli probe crash caused by excessive spin, report concludes

The Schiaparelli probe suffered a botched landing on the Martian surface as it briefly spun out of control, confusing the computer systems onboard, an official report concluded today. As the parachute was deployed, the lander rotated at a faster acceleration than expected. It caused the “Guidance Navigation and Control” …

Experimental satellite-slinger seeks cargo: What could go wrong?

If you've got an application for a small satellite and a stomach for risk, the European Space Agency wants to hear from you. Next year, it's planning a multi-launch demonstration from its Vega spacecraft on a proof-of-concept flight for the Small Satellites Mission Service. The test launch of the Small Satellites Mission …

European Space Agency slaps CC licences on its pics and vids

The European Space Agency has flung the data doors open: from today, it's adopted an open access policy for its trove of images and videos. As the agency explains, its adoption the Creative Commons Attribution – ShareAlike 3.0 Intergovernmental Organisation (it even abbreviates to a mouthful: CC BY SA IGO 3.0) licence as its …

If at first you don't succeed, send another Mars lander – this time a deep driller

Undeterred by the crash of the Schiaparelli Mars probe during the first ExoMars mission, the European Space Agency has signed off contracts that will hopefully deposit a new and more advanced lander directly on the Martian Surface. In one piece. In a ceremony in Rome, ESA inked a deal with private firm Thales Alenia Space to …

ExoMars probe snaps photos of your next dystopian home world when Earth goes to crap

Video The European Space Agency's ExoMars orbiter has beamed back its first photos and sensor readings of the Red Planet after circling the harsh dust world. The agency's astro-boffins needed some good news: last month, their Schiaparelli Mars lander – which was dropped from the ExoMars craft – smashed onto the Martian surface after …

ESA: Sorry about Schiaparelli, can we have another €400 mill?

Later this week in Lucerne, Switzerland, the European Space Agency (ESA) will ask its 23 member states' ministers for a €400 million top-up to its ExoMars program. In an audio conference on Friday, director of human spaceflight and robotic exploration David Parker said the cash injection “includes all the technical work needed …

ESA lofts one astronaut and four Galileo satellites into orbit

It has been a good 24 hours for the European Space Agency. Not only has its first four-in-one Galileo satellite launch gone flawlessly, but ESA astronaut Thomas Pesquet is on his way to the International Space Station. At 1306 GMT on Thursday, an Ariane 5 rocket lifted off from its spaceport in Kourou, French Guiana, carrying …

Smoking hole found on Mars where Schiaparelli lander, er, 'landed'

Pic The European Space Agency has spotted what it assumes is what's left of its Schiaparelli lander that smashed into the Martian surface this week. NASA has been helping its European cousin out with use of the Mars Reconnaissance Orbiter (MRO): the satellite's low-resolution CTX camera has picked up two new objects on the surface …

ExoMars update: Schiaparelli probe's parachute malfunctioned

The status of the Schiaparelli probe remains uncertain, leaving scientists at the European Space Agency baffled after the lander’s signal cut out unexpectedly. At a press conference this morning, ESA’s Director General, Johann-Dietrich Wörner, said the agency has not explicitly ruled the landing process as a fail, and is in …

Radio glitch as Schiaparelli lander probe splits from ExoMars mothership

The European Space Agency's Schiaparelli lander has parted from the Trace Gas Orbiter that was its companion on the ExoMars mission and is on track for its planned Wednesday landing on the red planet. But the European Space Agency is yet to explain a radio glitch that took place along the way. At 17:02 Central European Summer …

ExoMars arrives at the Red Planet on Sunday

Grab some popcorn, space enthusiasts, because this coming weekend the joint European Space Agency/Roscosmos “ExoMars” mission will arrive at Mars. ExoMars broke the surly bonds of Earth last March and has since proven itself capable of taking photos and sending them home on a 2 Mbit/s link. Now for the hard part. The mission …
