An unexpectedly strong blast from the Sun hit Mars this month, observed by NASA missions in orbit and on the surface.
Imagine moving satellites to higher orbits, collecting space debris, and dedicated launches for small satellites. These are the winning entries of ESA's call for ideas on new commercial space transportation services.
A winged spacecraft will soon take off with four NASA-supported technology experiments onboard. Virgin Galactic's SpaceShipTwo will separate from the WhiteKnightTwo twin-fuselage carrier aircraft and continue its rocket-powered ...
We're in for a pre-Christmas treat this weekend, as the cosmos entertains us with two equally exciting gifts: the Geminid meteor shower and the interplanetary comet 46P/Wirtanen.
The Geminids meteor shower peaks on the mornings of December 13 and 14, 2018 – but if you look up any time there's a clear night sky up until December 17, you might just catch a glimpse of a Geminid meteor.
Sometimes it's all about perspective. This very convincing image of a conjoined moon masquerading as a snowman is actually two separate Saturnian moons – Dione and Rhea – taken from such an angle by the international ...
As Earth's magnetic shield fails, so do its satellites. First, our communications satellites in the highest orbits go down. Next, astronauts in low-Earth orbit can no longer phone home. And finally, cosmic rays start to bombard ...
The first 'Pioneer' mission lifted off early this morning from Sriharikota, India, with the two inventive little nanosatellites now circling the Earth, ready for action.
South Korea has launched a single-stage rocket to test a locally made engine as part of efforts to place a satellite into orbit.
Vega is proving its reliability. Based on this heritage, ESA and European industry are building new elements that will increase Vega's performance, capabilities and flexibility from mid-2019.
