NASA has selected proposals for two new instruments that will observe changes in global vegetation from the International Space Station. The sensors will give scientists new ways to see how forests and ecosystems are affected by changes in climate or land use change.
On Monday, commercial spaceflight balloon company World View Enterprises announced it will “fly research and education payloads during its balloon test flight phase as part of its newly launched Pathfinder program.”
The European Space Agency’s (ESA) fifth and final Automated Transfer Vehicle (ATV-5) launched Tuesday atop an Ariane 5 rocket from Kourou, French Guiana, at 7:47 p.m. EDT.
A team of international researchers has discovered a new type of cool burning flames that could lead to cleaner, more efficient engines for cars.
ESA’s Venus Express spacecraft has climbed to a new orbit following its daring aerobraking experiment, and will now resume observations of this fascinating planet for at least a few more months.
After almost two decades with NASA, including two space shuttle missions, astronaut Mike Massimino left the space agency Monday for a full-time position with Columbia University in New York.
For decades, scientists have been debating over a fog of low-energy X-rays that has been observed over the entire sky. An international group of scientists has used a NASA-funded instrument to resolve this debate.
A United Launch Alliance (ULA) Delta IV rocket successfully launched the AFSPC-4 mission for the U.S. Air Force on July 28 at 7:28 p.m. EDT from Space Launch Complex-37.
After losing contact with a satellite filled with geckos taking part in an unusual reproductive experiment late last week, Russian space officials have re-established communication with the Photon-M probe.
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 from the moon's underground sea all the way to its surface.
NASA's Opportunity Mars rover, which landed on the Red Planet in 2004, now holds the off-Earth roving distance record after accruing 25 miles (40 kilometers) of driving. The previous record was held by the Soviet Union's Lunokhod 2 rover.
Researchers at NASA's Jet Propulsion Laboratory in Pasadena, California, are implementing a printing process that transitions from one metal or alloy to another in a single object.
ESA has welcomed the arrival of Pharao, an important part of ESA’s atomic clock experiment that will be attached to the International Space Station in 2016.
After spending the past four months living and working in a simulated Mars environment in Hawaii, six volunteers emerged from the mock base on Friday, various media outlets reported over the weekend.
Surrey Satellite Technology Ltd (SSTL) has released an image taken by an inspection camera on board TechDemoSat-1 to mark the completion of the Launch and Early Operations Phase (LEOP) for the satellite, which was launched on 8th July.
Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before.
NASA is taking steps to protect its Mars orbiters, while preserving opportunities to gather valuable scientific data, as Comet C/2013 A1 Siding Spring heads toward a close flyby of Mars on Oct. 19.
Surface structures are becoming visible in new images of comet 67P/Churyumov-Gerasimenko taken by the scientific imaging system OSIRIS onboard the European Space Agency's Rosetta spacecraft.
A new home-grown instrument based on bundles of optical fibers is giving Australian astronomers the first 'Google street view' of the cosmos — incredibly detailed views of huge numbers of galaxies.
NASA's James Webb Space Telescope and Chandra X-ray observatory have something in common: a huge test chamber used to simulate the hazards of space and the distant glow of starlight.
