ESA's LISA Pathfinder experiment launches to explore Einstein’s General Theory of Relativity

ESA's LISA Pathfinder experiment has successfully launched atop a Vega rocket from the agency's spaceport in Kourou, French Guiana, and completed initial maneuvers required to place the probe in a low, stable orbit. The experiment will seek to observe tiny ripples in space known as gravitational waves, which were first predicted by Albert Einstein in his General Theory of Relativity.Read More

Galileo satellites to test Einstein's General Theory of Relativity

Having failed to achieve their intended orbit following a launch in August 2014, a pair of ESA Galileo satellites are being re-tasked to test Einstein's General Theory of Relativity. More precisely, the satellites will examine the effects of gravity on the passage of time, observing the phenomenon in a detail four times greater than any previous mission.Read More

Mars Express sheds light on rare Martian auroras

Auroras are common spectacles in Earth's Arctic and Antarctic regions, but on Mars they're rare and not nearly as attention grabbing. Visible only in the ultraviolet, they may not be as entertaining as their earthly counterparts, but after a decade of measurements by ESA’s unmanned Mars Express orbiter, the rare Martian auroras are telling scientists a lot about the local vestigial magnetic fields of the Red Planet.Read More
