OSIRIS-Rex_Touchdown_on_Bennu_Scared_NASA_Scientists,_Luckily_They_Planned_For_Everything

OSIRIS-REx Touchdown on Bennu" likely refers to a key event in the mission when the spacecraft made contact with the asteroid's surface to collect a sample. During this maneuver, OSIRIS-REx extended a robotic arm called TAGSAM (Touch-And-Go Sample Acquisition Mechanism) to briefly touch Bennu's surface and capture a sample of regolith (loose asteroid material). This sample was later sealed and prepared for a return journey to Earth.
