ESA’s Aeolus satellite spent nearly two months in a thermal–vacuum chamber to make sure that its novel instrument will work as it should in space. Aeolus carries one of the most sophisticated instruments ever to be put into orbit: Aladin, with two powerful lasers, a large telescope and very sensitive receivers. It will be the first such satellite mission to measure Earth’s winds from space.
