Seven tiny grains captured by Stardust likely visitors from interstellar space
Since 2006, when NASA's Stardust spacecraft delivered its aerogel and aluminum foil dust collectors to Earth, a team of scientists has combed through the collectors in search of rare, microscopic particles ...
Rosetta measures comet's temperature
(Phys.org) —ESA's Rosetta spacecraft has made its first temperature measurements of its target comet, finding that it is too hot to be covered in ice and must instead have a dark, dusty crust.
SpaceX rocket explodes during test flight
A SpaceX rocket exploded in midair during a test flight, though no one was injured, as the company seeks to develop a spacecraft that can return to Earth and be used again.
Cassini tracks clouds developing over a Titan sea

Cassini spacecraft reveals 101 geysers and more on icy Saturn moon
Scientists using mission data from NASA's Cassini spacecraft have identified 101 distinct geysers erupting on Saturn's icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach ...
Voyager spacecraft might not have reached interstellar space
In 2012, the Voyager mission team announced that the Voyager 1 spacecraft had passed into interstellar space, traveling further from Earth than any other manmade object.
Amazing raw Cassini images from this week
When Saturn is at its closest to Earth, it's three-quarters of a billion miles away—or more than a billion kilometers! That makes these raw images from the ringed planet all the more remarkable.
Image: Rosetta spies comet surface variations
A new image of comet 67P/Churyumov-Gerasimenko shows the diversity of surface structures on the comet's nucleus. It was taken by the Rosetta spacecraft's OSIRIS narrow-angle camera on August 7, 2014. At the ...
Orbital cargo ship makes planned re-entry to Earth
Orbital Sciences Corporation's unmanned Cygnus cargo ship disintegrated as planned Sunday as it re-entered Earth's atmosphere after a month-long resupply mission to the International Space Station.
ISEE-3 completes lunar flyby, begins a citizen science program
The journey began on August 12, 1978 from Cape Canaveral on a Delta II launch vehicle. Now after 36 years and 30 billions miles of travel around the Sun—as well as a crowd-funded reboot of the spacecraft ...
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.
Watch Pluto and Charon engage in their orbital dance
Now here's something I guarantee you've never seen before: a video of the dwarf planet Pluto and its largest moon Charon showing the two distinctly separate worlds actually in motion around each other! Captured ...
