Handshake from space with ESA's Haptics-2 experiment
This deceptively modest force-feedback joystick in ESA's Telerobotics Laboratory is set to become a piece of space history.
Three candidates for ESA's next medium-class science mission

Image: How liquids of different densities behave in weightlessness
In space everything is different. In a world with no up or down, hot air does not rise and liquids behave differently, too. In your kitchen, salad dressings will separate into the heavier vinegar on the bottom and the lighter ...
