Until recently the idea of launching a satellite into space was an expensive business and the preserve of governments, international space organisations and multi-million dollar companies.
Throughout his career Ronald Greeley was passionate about exploring Mars, so it's fitting that the late Arizona State University professor's name will grace maps of the Red Planet.
First classified a planet, then an asteroid and then a "dwarf planet" with some traits of a moon—the more scientists learn about Ceres, the weirder it becomes.
Researchers have long known that there is water in the form of ice on Mars. Now, new research from NASA's Mars rover Curiosity shows that it is possible that there is liquid water close to the surface of ...
Measurements made by Rosetta and Philae during the probe's multiple landings on Comet 67P/Churyumov-Gerasimenko show that the comet's nucleus is not magnetised.
Once every 20 or 30 years, a superstorm greater than Earth breaks out on Saturn and whips around the ringed planet in a violent spectacle that rages for months on end.
The best picture we have of Pluto is a blurry, pixelated blob, but that is about to change when a NASA spacecraft makes the first-ever flyby of the dwarf planet.
On Oct. 12, 2017, the asteroid 2012 TC4 is slated to whizz by Earth dangerously close. The exact distance of its closest approach is uncertain, as well as its size. Based on observations in October 2012 when ...
SpaceX's latest attempt at recycling its Falcon 9 rocket by landing it upright on an ocean platform failed Tuesday, after a successful launch of its cargo mission to space.
Europe's comet lander Philae has remained obstinately silent since a new bid was launched to communicate with it, mission chiefs said Tuesday, but chances for contact were improving daily.
SpaceX's unmanned Dragon cargo ship blasted off Tuesday toward the International Space Station, carrying a load of food and supplies for the astronauts living in orbit.
As NASA's MESSENGER mission draws to a close, an on-board science instrument that mapped the surface of Mercury is helping the navigation team with the spacecraft's low-altitude passes.
A versatile instrument developed by Lawrence Livermore National Laboratory (LLNL) scientists and riding on the first spacecraft to ever orbit Mercury is causing researchers to rethink their theories on the ...
After extraordinary science findings and technological innovations, a NASA spacecraft launched in 2004 to study Mercury will impact the planet's surface, most likely on April 30, after it runs out of propellant.
SpaceX's unmanned Dragon cargo ship arrived Friday at the International Space Station, carrying a load of food and supplies for the astronauts living in orbit.
