A "type 1" mission where a scout is launched first and collects close-up data about the asteroid before the main impactor is launched, in order to better aim the shot for maximum effect.

Yarkovsky effect measurements from the OSIRIS-REx probe were thus used to fine-tune Bennu's trajectory. The effects are minuscule though can adjust Bennu’s motion over long-enough periods of time. The heat is then radiated back into space as it cools down, releasing infrared energy that generates a small push on the asteroid. As Bennu spins, the side of its body facing the Sun absorbs heat and rotates away. We know there are a lot of, er, distractions right now but NASA's got some sweet video of its asteroid rubble raiserĪlthough the researchers had a good idea of the asteroid’s path, it can be nudged by something called the Yarkovsky effect.We got it!

The team had to model the gravitational interactions between the asteroid and the Sun, and other planets and their satellites, as well as more than 300 other space rocks, and pressure from the solar wind. There are multiple factors to consider when trying to map its path as it travels through the Solar System. OSIRIS-REx has provided scientists with the most accurate data yet on Bennu’s size, shape, mass, spin, chemical composition, and orbital motion.
