These are, in fact, the droids that NASA and its research partners are looking for. Inspired by a floating droid battling Luke Skywalker in the film Star Wars, the free-flying satellites known as Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying aboard the International Space Station since Expedition 8 in 2003.
Fruit flies bred in space are offering scientists a clue as to how astronauts' immune systems may be damaged during prolonged space travel.
Two tiny, cube-shaped research satellites hitched a ride to Earth orbit to validate new hardware and software technologies for future NASA Earth-observing instruments.
The cube satellites, or “CubeSats,” which typically have a volume of exactly 33.814 ounces (1 liter), were launched on a United Launch Alliance Atlas V rocket late last week from California's Vandenberg Air Force Base as part of the NROL-39 GEMSat mission.
The first Cygnus Spacecraft to visit the International Space Station (ISS), the G. David Low, departed the station at 7:31 AM EST on October 22, 2013. The Cygnus spacecraft is the latest in a long line of cargo vehicles built to resupply the orbital outposts that humanity has positioned in the heavens.
For NASA and its dozens of missions, data pour in every day like rushing rivers. Spacecraft monitor everything from our home planet to faraway galaxies, beaming back images and information to Earth. All those digital records need to be stored, indexed and processed so that spacecraft engineers, scientists and people across the globe can use the data to understand Earth and the universe beyond.
NASA's Cassini spacecraft has detected propylene, a chemical used to make food-storage containers, car bumpers and other consumer products, on Saturn's moon Titan.
Scientists have provided the most comprehensive details yet of the journey energy from the sun takes as it hurtles around Earth's magnetosphere.
This week sees the start of ESA’s next underground training course for astronauts. Six new and experienced astronauts from all over the world will work together to overcome the difficulties of working in a new environment performing a full scientific programme with limited supplies – similar to working on the International Space Station.
During its five-year primary mission, NASA's Fermi Gamma-ray Space Telescope has given astronomers an increasingly detailed portrait of the universe's most extraordinary phenomena, from giant black holes in the hearts of distant galaxies to thunderstorms on Earth.
NASA scientists have established a new way to use satellites to measure what's occurring inside plants at a cellular level.
Astronomers using NASA's Hubble Space Telescope have determined the orbital motion of two distinct populations of stars in an ancient globular star cluster, offering proof they formed at different times and providing a rare look back into the Milky Way galaxy's early days.
Two NASA spacecraft, one studying the Saturn system, the other observing Mercury, are maneuvering into place to take pictures of Earth on July 19 and 20.
Researchers from Northeastern University are among the many scientists helping NASA use the weightlessness of space to design stronger materials here on Earth.
NASA and a Texas company are exploring the possibility of using a "3D printer" on deep space missions in a way where the "D" would stand for dining.
Studying complex systems like ecosystems can get messy, especially when trying to predict how they interact with other big unknowns like climate change.
Scientists have put to bed a theory about space brains, which will be a great relief to those who have trouble sleeping over such matters.
A European Space Agency (ESA) business incubation start-up company is helping major car manufacturers to develop electric vehicle concepts and improve safety systems by turning ideas quickly into virtual prototypes.
A few years ago, researchers revealed that the universe is expanding at a much faster rate than originally believed — a discovery that earned a Nobel Prize in 2011.
SpaceX managed to successfully launch its third flight to the International Space Station (ISS) this morning despite an issue with the Dragon spacecraft's thruster pods.
Most people would probably expect to find millions of dollars worth of cutting-edge equipment at a NASA research facility. And they would be right, of course, but there may also be some surprises waiting for the unsuspecting visitor.
