Imagine parallel parking a 15-passenger van into just two to three parking spaces surrounded by two-story boulders. On Oct. 20, a University of Arizona-led NASA mission 16 years in the making will attempt the astronomical equivalent more than 200 million miles away. A NASA mission called OSIRIS-REx will soon attempt to touch the surface of an asteroid and collect loose rubble. OSIRIS-REx is the United States’ first asteroid sample return mission, aiming to collect and carry a pristine, unaltered sample from an asteroid back to Earth for scientific study. The spacecraft will attempt to touch the surface of the asteroid Bennu, which is hurtling through space at 63,000 miles per hour. If all goes according to plan, the spacecraft will deploy an 11-foot-long robotic arm called TAGSAM – Touch...

On Feb. 21, 2019, we shot an asteroid. More precisely, the Hayabusa2 spacecraft, built and operated by the Japan Aerospace Exploration Agency, or JAXA, fired a 5-gram metal projectile into the surface of the near-Earth asteroid Ryugu, a spinning-top-shaped body about 1 kilometer across and some 350 million kilometers from Earth. This projectile disrupted the surface of the asteroid, allowing Hayabusa2 to capture some of the lofted material and tuck it safely away on board. Having departed from Ryugu in November 2019, Hayabusa2 is expected to fly past Earth in late 2020 and release its samples in a reentry capsule for detailed analyses in labs across the world. Asteroid Ryugu photographed from a distance of about 12 miles (20 kilometers) looks just gray and bland, but a close-up provides m...
