On Thursday (Jan. 14), the European Space Agency's Mars Express orbiter is set to pay Phobos a visit in what will be the mission's closest flyby of the Martian moon this year.
After more than eleven years orbiting Saturn, NASA's Cassini spacecraft has made its last-ever targeted flyby of Enceladus, the big little moon that has intrigued scientists with its southern ice geysers since Cassini first spotted them in 2005.
NASA’s Cassini spacecraft, which has been sailing around the Saturn system for more than 11 years, will make its final close approach to the ocean-bearing moon Enceladus on Saturday.
It's not in a galaxy far, far away or even another star system -- this alien world is right in our planetary backyard, a mere 900 million miles away in orbit around Saturn.
After Cassini's 'deep-dive' into Enceladus' watery plumes, evidence mounts for life-friendly environments inside the Saturn moon's ocean.
There are few views in Saturnian orbit that are more satisfying than seeing two or more moons in the same frame -- particularly when they align.
Mars' moon, Phobos, is doomed and scientists have some new findings about its possible fate. What else do we know about Phobos?
Scientists have known for some time that Phobos, the larger of Mars’ two small moons, is a victim of gravity, edging closer toward its parent planet.
