For a month’s time, Ny-Ålesund will be home to the rocket team behind NASA’s VISIONS-2 mission, short for Visualizing Ion Outflow via Neutral Atom Sensing-2. They have ventured to this extreme place for an up-close look at atmospheric escape, the process whereby Earth is slowly leaking its atmosphere into space. Understanding atmospheric escape on Earth has applications all over the universe — from predicting which far off planets might be habitable, to piecing together how Mars became the desolate, exposed landscape it is today. VISIONS-2 is scheduled to launch no earlier than Dec. 4, 2018.

Led by Doug Rowland of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, VISIONS-2 is a sounding rocket mission, a type of suborbital rocket that makes brief, targeted flights into space before falling back to Earth just a few minutes later. Sounding rockets are unique among scientific spacecraft for their superior dexterity: They can be carted to remote locations, where they are aimed and shot into short-lived events — like the sudden formation of the #aurora borealis — at a moment’s notice.
