For the launch of Sentinel-2A, ESA is inviting you to take part in a photo contest focusing on the theme of 'colour vision'. Enter for a chance to win a trip to ESA's operations centre for the satellite's launch event.
Light can come in many frequencies, only a small fraction of which can be seen by humans. Between the invisible low-frequency radio waves used by cell phones and the high frequencies associated with infrared light lies a fairly wide swath of the electromagnetic spectrum occupied by what are called terahertz, or sometimes submillimeter, waves.
NASA is extending an opportunity to college and university teams to propose small spacecraft technology projects that they can conduct in collaboration with NASA researchers.
ESA astronaut Samantha Cristoforetti sent this greeting to participants at SpaceApps Challenge including in Rome, taking place over the weekend of 11 and 12 April. This is part of the International Space Apps Challenge initiated by NASA, with events in cities all over the world.
This building block of a future Moon base, 3D-printed from simulated lunar material, is now on show at the Hypervital exhibition, part of the International Design Biennale in Saint-Etienne, France.
Engineers at NASA's Glenn Research Center are advancing the propulsion system that will propel the first ever mission to redirect an asteroid for astronauts to explore in the 2020s.
At any given moment, our sun emits a range of light waves far more expansive than what our eyes alone can see: from visible light to extreme ultraviolet to soft and hard X-rays.
One of humanity's oldest technologies, the humble fishing net, may yet find a new role in space: bringing down dead satellites.
On 18 March 1965 Russian cosmonaut Alexei Leonov became the first person to perform a spacewalk, when he ventured from his Voskhod spacecraft.
It's tricky to get a spacecraft to land exactly where you want. That's why the area where the Mars rover Curiosity team had targeted to land was an ellipse that may seem large, measuring 12 miles by 4 miles (20 by 7 kilometers).
College students have the opportunity to be at the forefront of innovation for NASA's journey to Mars by designing systems for future space habitats and exploration systems through the agency's Exploration Habitat (X-Hab) Academic Innovation Challenge.
Residents in the Southern Hemisphere's mid-latitudes, such as Argentina and South Africa, may catch a glimpse of a large NASA heavy-lift scientific balloon as it travels around the globe on a potentially record-breaking flight.
Four teams of university students have been selected to develop and conduct their hypergravity experiments during ESA's sixth 'Spin Your Thesis!' campaign, to be held 7-18 September 2015.
In the cold, nighttime skies over Alaska, a NASA Oriole IV suborbital sounding rocket blasted off from the Poker Flat Research Range today at 3:41 a.m. (MST)
The Planetary Society today announced the first of its LightSail spacecraft will embark on a May 2015 test flight.
The future of space communications was illuminated by this test, as a laser beam was shone from ESA's Optical Ground Station in Tenerife to the International Space Station in orbit.
If you sweep a laser pointer across the Moon fast enough, you can create spots that actually move faster than light. Anyone can do it.
Plans for the construction of the world's largest digital camera at the Department of Energy's SLAC National Accelerator Laboratory have reached a major milestone.
In parallel with the Proba minisatellite missions, ESA is now also utilising much smaller 'CubeSat' nanosatellites. These are employed for the In-Orbit Demonstration (IOD) of miniaturised technologies and for small payload-driven missions.
A NASA-sponsored website designed to crowdsource analysis of data from the agency's Wide-field Infrared Survey Explorer (WISE) mission has reached an impressive milestone.
