NASA’s OSIRIS-REx to Attempt a “Grab-and-Snatch” on Asteroid Bennu Today
Today, OSIRIS-REx will attempt a historic feat for NASA -- To collect the first samples from an asteroid’s surface. The spacecraft will maneuver down to the selected Nightingale site on Bennu’s rocky and dusty surface to collect a sample for return to Earth. The OSIRIS-REx spacecraft will attempt to gather at least 2 ounces of regolith from the asteroid Bennu. Since Bennu is so far away, the operators on the ground will issue instructions to the spacecraft and then it will autonomously approach Bennu and extend its robotic arm, called the Touch-And-Go Sample Acquisition Mechanism (TAGSAM). If all goes well, TAGSAM will stow the gathered material and begin the trip home for arrival in 2023.
