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

Rosetta spacecraft detects molecular oxygen outgassing from Comet 67P

Despite being the third most abundant element in the Universe, molecular oxygen, or O₂, is relatively rare off Earth. That's why it raised a few eyebrows at ESA when the space agency's Rosetta spacecraft discovered oxygen molecules jetting out of the nucleus of Comet 67P/Churyumov–Gerasimenko. According to the Rosetta team, the oxygen is outgassing in such abundance that its presence may date back to the formation of the comet over 4.6 billion years ago.Read More

Oxia Planum firms at landing site for ExoMars 2018 mission

ESA has named the Oxia Planum region as the primary candidate for the landing site of the ExoMars 2018 Mars mission. The Russo-European mission to the Red Planet is the second of two missions of the ExoMars program and is aimed at demonstrating new technologies and seeking signs of past or present life. Consisting of a lander and rover, the mission is scheduled to launch in May 2018 with a landing in January 2019.Read More

ESA's GomX-3 CubeSat goes online

The European Space Agency has declared that its miniature GomX-3 technology demonstration satellite is in good health and ready to begin its primary mission. Deployed on October 5 from the International Space Station, the CubeSat will spend six-months testing new radio technology for tracking civil aircraft in previously inaccessible regions of the world and measuring telecom satellite signal quality.Read More

SkinSuit designed to reduce harmful physical effects of weightlessness tested on ISS

The crew of the International Space Station (ISS) got a fashion show with a medical twist last month as Denmark’s first astronaut, Andreas Mogensen, donned a SkinSuit designed to counteract the harmful effects of prolonged periods of weightlessness on the human body. Developed as part of an international effort led by RMIT University in Melbourne, Australia, the new suit is designed to simulate the pressures of normal gravity to prevent unhealthy stretching of the spine.Read More
