NASA is just one week away from the epic landing of its OSIRIS-REx asteroid sample-return capsule, which is packed with pieces of the asteroid Bennu. The landing, which is on track for Sept. 24, 2023, will mark the end of OSIRIS-REx’s primary 7-year mission that began with a launch in 2016 and sample-collection at Bennu in October 2020

Scientists are excited, but also on tenterhooks, as they prepare for OSIRIS-REx’s return to Earth. The spacecraft will slam into Earth’s atmosphere, protected by a heat shield, and reach speeds of up to 27,000 mph before deploying drogue and main parachutes to slow itself to a more manageable 10 mph.
