NASA has reported that its Curiosity rover has made another significant discovery on Mars. Curiosity has drilled into a rock that contains clay minerals – an indication of formation in, or substantial alteration by, neutral water. Scientists say the find is one more step towards showing conditions on Mars in the distant past could have [...]

Curiosity Mars rover has been put into “safe mode” after a computer glitch caused by corrupted files. NASA’s Curiosity robot, which is analyzing rock samples on Mars, is now running from a back-up computer. NASA scientists are looking into possible causes for the files on the robot’s flash memory being damaged. The fault means the [...]

Fragments from the meteorite that struck Russia’s Urals region on Friday, injuring some 1,200 people, have been found around a frozen lake, Russian scientists say. The fragments were detected around a frozen lake near Chebarkul, a town in the Chelyabinsk region, where the meteorite is believed to have landed. Viktor Grohovsky, of the Urals Federal [...]

NASA’s Messenger probe to Mercury has shown off a stunning new color map of the planet. The map comprises thousands of images acquired by the spacecraft during its first year in orbit. This is not how we would see Mercury, which would look like a dull, brownish-grey globe to our eyes. Rather, the map represents [...]

Asteroid 2012 DA14, which is as large as an Olympic swimming pool, will race past the Earth on Friday at a distance of just 27,700 km (17,200 miles) – the closest ever predicted for an object of that size. It will pass closer even than the geosynchronous satellites that orbit the Earth, but there is [...]

NASA’s Curiosity rover on Mars has finally drilled deep enough into a rock to acquire a powdered sample for analysis. The fine grey tailings from the 6cm-hole will be sieved and inspected before being delivered to the robot’s onboard labs in the coming days. It will represent a historic first in planetary exploration – never [...]

Astronomers say that one in six stars host an Earth-sized planet in a close orbit – suggesting a total of 17 billion such planets in our galaxy. The result comes from an analysis of planet candidates gathered by NASA’s Kepler space observatory. The Kepler scientists also announced 461 new planet candidates, bringing the satellites’ total [...]

NASA’s Curiosity rover is very close to drilling into its first Martian rock, with the set-up operation likely to begin next week. After breaking for the holidays, the mission team would be raring to undertake the task in the coming days, said lead scientist John Grotzinger. The robot has driven about 650 m from its [...]

NASA is to test color-changing lights on the International Space Station (ISS) as part of efforts to help astronauts on board sleep. The US space agency will initially swap a fluorescent panel with a solid-state lighting module (SSLM) containing LEDs which produces a blue, whitish or red-colored light depending on the time. It says the [...]

NASA has admitted it mistook a mountain in India for Mount Everest when it posted online a picture taken from space. NASA initially said the photo – by Russian cosmonaut Yuri Malenchenko – showed the world’s tallest summit. The image was quickly picked up by a number of media outlets, but NASA removed it after [...]

The first commercially contracted re-supply mission to the International Space Station (ISS) has begun. A Falcon rocket carrying a Dragon cargo capsule lifted clear of Cape Canaveral in Florida at 20:35 (00:35 GMT). The robotic Dragon ship will deliver 400 kg of food, clothing, experiments and spares to the orbiting platform’s six astronauts. It is [...]

Curiosity rover has completed its first close-contact science on Mars. The robot pushed its arm instruments up against a pyramidal rock to assess the atomic elements that were present. The rock – dubbed “Jake Matijevic” after a late rover engineer – was not expected to have high research value. Rather, it was regarded as an [...]

Russian Soyuz capsule has returned to Earth with its three-man crew after they spent 123 days at the International Space Station. Two Russians, Gennady Padalka and Sergei Revin, and their American colleague Joe Acaba made the safe return in Kazakhstan on Monday morning. Another crew of three who took off in May remain on the [...]

Curiosity rover has measured the Red Planet’s atmospheric composition. NASA’s robot sucked the air into its big Sample Analysis at Mars (SAM) instrument to reveal the concentration of different gases. It is the first time that the chemistry of the atmosphere has been tested from the surface of the planet since the Viking landers in [...]

NASA’s Dawn satellite has left the giant Asteroid Vesta after 13 months of study. A signal from Dawn probe confirming that it had escaped the gravitational bounds of the 530 km-wide rock was received by NASA on Wednesday. The spacecraft’s ion engine is now pushing it on to an even bigger target in the belt [...]

NASA has discovered the Arctic has lost more sea ice this year than at any time since satellite records began in 1979. Scientists involved in the calculations say it is part of a fundamental change. What is more, sea ice normally reaches its low point in September so it is thought likely that this year’s [...]

NASA’s Curiosity rover, which landed on Mars two weeks ago, turned its six wheels briefly on Wednesday to satisfy engineers that its locomotion system was in full working order. Curiosity is a sophisticated mobile science laboratory. It has been built to drive at least 20 km across the Martian landscape to investigate whether the planet [...]

NASA has reported its first setback in its Curiosity rover mission to Mars. A sensor on the robot’s weather station that takes wind readings has sustained damage. The mission team stresses this is not a major problem and will merely degrade some measurements – not prevent them. It is not certain how the damage occurred [...]

Curiosity rover is getting ready to zap its first Martian rock. A small stone lying just to the side of the vehicle at its landing site on the floor of Gale Crater has been selected as a test target for the ChemCam laser. The brief but powerful burst of light from this instrument will vaporize [...]

Hypersonic jet X-51A WaveRider has been tested by US military in a bid to reach Mach 6 (4,300 mph; 6,900 km/h) above the Pacific Ocean. At that speed it could travel from London to New York in about an hour. Results from the test flight have not yet been released. The Pentagon and NASA hope [...]

NASA has released the first full color mosaic from its Curiosity rover on the surface of Mars. Scientists have remarked that the rover’s surroundings resembled parts of the southwestern US. Curiosity’s ultimate goal is to drive towards a peak – informally known as Mount Sharp – to study its rocks. Shown in the mosaic is [...]

NASA’s Curiosity rover has lifted its mast and used its high navigation cameras for the first time. The robot vehicle has returned black and white images that capture part of its own body, its shadow on the ground and views off to the horizon. Spectacular relief – the rim cliffs of the crater in which [...]

Images of the surface of Mars taken by the Curiosity rover as it made its historic descent yesterday have now been released. NASA has provided almost 300 thumbnails from a sequence of pictures that will eventually be run together as a color hi-def movie. Visible in the timelapse is the heatshield discarded by the vehicle [...]

NASA’s Curiosity rover has just landed on Mars. The one-ton vehicle was reported to have landed in a deep crater near the planet’s equator at 06:32 BST (05:32 GMT). It will now embark on a mission of at least two years to look for evidence that Mars may once have supported life. A signal confirming [...]

The Curiosity rover remains perfectly on course to make its Monday (GMT) landing on the Red Planet, NASA says. The NASA robot’s flight trajectory is so good engineers cancelled the latest course correction they had planned. To be sure of touching down in the right place on the surface, the vehicle must hit a box [...]
