NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid  Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid.

The sport of roller skiing has long been plagued with a concern. The wheels of the skis roll differently, which can cause the individual’s speed to vary considerably, and as such, the finish times can be impacted by several minutes. Now students at Chalmers University of Technology in Sweden have developed a new measuring instrument and method to standardise the resistance of the wheels – and make the sport fairer. Starting this year, the Swedish Ski Association will base its official guidelines for recommended wheels on the students' measurement method.
