Tall boulder rolls down martian hill, lands upright
(Phys.org) —A track about one-third of a mile (500 meters) long on Mars shows where an irregularly shaped boulder careened downhill to its current upright position, seen in a July 3, 2014, image from the ...
Indian spacecraft on course to enter Mars orbit (Update)
India will soon know if its first interplanetary mission will achieve its goal, when a spacecraft built with homegrown technology for a remarkably low price tag of $75 million begins its final maneuvers into ...
How can we find tiny particles in exoplanet atmospheres?
It may seem like magic, but astronomers have worked out a scheme that will allow them to detect and measure particles ten times smaller than the width of a human hair, even at many light-years distance. ...
Dr. Chris Okubo discusses the most detailed geologic map of Mars
Earlier this month, the U.S. Geological Survey (USGS) released its highest-resolution geologic map of Mars. The new geologic and structural map uses the highest-resolution, orbiter-based images currently ...
A salty, martian meteorite offers clues to habitability
Life as we know it requires energy of some sort to survive and thrive. For plants, that source of energy is the Sun. But there are some microbes that can survive using energy from chemical reactions. Some ...
Comet-chasing probe closes in on target
A comet-chasing spacecraft on a mission to land on a fizzing ball of ice and dust later this year has begun a crucial slow-down maneuver to avoid flying past its target.
Gecko grippers get a microgravity test flight (w/ Video)
There are no garbage trucks equipped to leave the atmosphere and pick up debris floating around the Earth. But what if we could send a robot to do the job?
UA-led HiRISE camera spots long-lost space probe on Mars
The UK-led Beagle 2 Mars Lander, thought lost on Mars since 2003, has been found partially deployed on the surface of the planet, ending the mystery of what happened to the mission more than a decade ago. ...
Signs of ancient Mars lakes and quakes seen in new map
Long ago, in the largest canyon system in our solar system, vibrations from "marsquakes" shook soft sediments that had accumulated in Martian lakes.
A giant among Earth satellites
The International Space Station has been called a stepping stone to other worlds.
Team suggests sublimating ice to propel CubeSats
Satellite gearing up to take EPIC pictures of Earth
The Deep Space Climate Observatory (DSCOVR) satellite is on its way to do something epic. NOAA's spacecraft, sent to monitor space weather, will use its Earth Polychromatic Imaging Camera (EPIC) to capture ...
Russia launches British comms satellite into space
Russia on Sunday carried out its first space launch of the year, using its commercial Proton rocket to send a British satellite into orbit.
Explainer: How do satellites orbit the Earth?
Take a look at the moon and it isn't hard to imagine it as a planet. A 3,476 kilometres-in-diameter ball of rock, with basalt plains and mountain ranges, whose gravitational pull produces tides here on Earth.
