You'd think that a planet with permanent day and night sides would be totally inhospitable. Without a sun to warm it up, the dark side would be freezing cold all the time. And with no respite from the solar onslaught, the light side would be scorching hot. But a new study suggests that exoplanets with this very predicament might in fact be habitable.
Boeing has announced that the first satellite with all-electric propulsion is now fully operational. Launched last March, the ABS-3A 702SP (small platform) satellite was formally handed over to its owner, Bermuda-based telecommunications company ABS, on August 31. It will provide communications services to the Americas, Europe, the Middle East, and Africa.
During a planned calibration maneuver, ESA's Mars Express spacecraft has captured a stunning shot of a huge swathe of the Martian environment. The image, snapped on February 25, captures a number of impressive features present on the surface of the Red Planet, including the Martian south pole, an enormous basin and two vast channels.
Last year, SpaceX unveiled its Crew Dragon, which is scheduled to begin ferrying astronauts to the International Space Station (ISS) in 2017. Now the company is giving the public a look at the interior. Sporting a minimalist design, it's intended to not only provide safety, but a considerable degree of comfort.
NASA has released more breathtaking images from the New Horizons spacecraft's Pluto encounter, showcasing the dwarf planet's surprisingly diverse geological features. The images come in the wake of the probe's high-velocity flyby, during which time the spacecraft collected vast quantities of data on one of the most enigmatic bodies in our solar system.
A new NASA image
release is granting the highest-resolution view of the now-famous
Occator crater – the most distinctive geological feature on the
dwarf planet Ceres to date. The images were snapped by NASA's Dawn
spacecraft at a height of 915 miles (1,470 km) as it continues to
observe Ceres from its third mapping orbit.
No bottles of champagne were broken, but Boeing’s CST-100 commercial crew transportation spacecraft officially has a new name. Intended to one day ferry astronauts to the International Space Station – and potentially paying customers to low-Earth orbit – the spacecraft is now known as the Starliner.
ESA astronaut Andreas Mogensen has successfully driven and manipulated an Earth-based rover whilst orbiting at a height of 400 km (249 miles) aboard the International Space Station (ISS). The control system used a sophisticated form of force-feedback that allowed Mogensen to determine when the rover's robotic arm met resistance. The technology has the potential to be used in a number of roles both in space and back on Earth, possibly taking human workers out of harms way.
When NASA's New Horizons probe made its historic flyby of Pluto on July 14, it gathered a wealth of information about the dwarf planet and its moons, but at a distance from Earth of over 3 billion mi (4.8 billion km), retrieving that data will take a very long time. To speed things up, NASA has begun an intensive download from the unmanned spacecraft that will return tens of gigabits of data over the next 12 months.
As demonstrated by the bumpy landing of ESA's Philae lander on comet 67P/Churyumov–Gerasimenko, exploring comets, asteroids, and small moons can be difficult due to their low gravity. Not only can landing on one be like trying to alight on a trampoline, but roving around their surfaces is next to impossible because the negligible gravity offers practically no traction. To overcome this, a team of engineers is developing Hedgehog, a completely symmetrical robot rover for low-gravity exploration that moves by hopping.
