How long did it take Osiris to reach Bennu?
After traveling for approximately two years, the spacecraft rendezvoused with asteroid 101955 Bennu in December 2018, and began 505 days of surface mapping at a distance of approximately 5 km (3.1 mi).
How did OSIRIS-REx collect the sample from Bennu?
While at the asteroid, OSIRIS-REx is surveying and mapping Bennu, navigating in close proximity to the asteroid, and will ultimately touch the surface for five seconds to gather a sample of the asteroid.
What is the speed of OSIRIS-REx?
The Sample Return Capsule will reach a top speed of 27,700 mph as it comes through the Earth's atmosphere. This is the second fastest man-made object to return to Earth as the Lockheed Martin-built Stardust capsule came back to Earth at 28,185 mph.

How far did OSIRIS-REx travel to Bennu?
OSIRIS-REx has entered the Post-TAG Observation (PTO) phase. Currently, the spacecraft is approximately 936 km from asteroid Bennu and approaching the at about 47 cm/s. Since October's sample collection event, the spacecraft had been slowly drifting away and ended up approximately 2,200 km from Bennu.
How much sample did OSIRIS-REx collect?
2.1 ounces OSIRIS-REx is an acronym for "Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer." The goal of the mission – collect a sample weighing at least 2.1 ounces (59.5 grams) from near-Earth asteroid 101955 Bennu (formerly known as 1999 RQ36) and then bring the sample to Earth.
When did OSIRIS-REx touch Bennu?
Oct. 20, 2020 NASA's OSIRIS-REx is the first U.S. mission to successfully collect a sample from an asteroid. On Oct. 20, 2020, the spacecraft briefly touched down on Bennu, an asteroid more than 200 million miles (321 million kilometers) from Earth, and grabbed dust and rocks from a sample site called Nightingale.
When did OSIRIS-REx leave Bennu?
Jun 04, 2021 NASA's OSIRIS-REx spacecraft is 328,000 miles, or 528,000 kilometers, away from the asteroid Bennu, having fired its engines on May 10 to initiate a return trip to Earth. The spacecraft is on track to deliver an asteroid sample to Earth on September 24, 2023.
Did OSIRIS-REx get a sample?
After releasing the sample capsule, OSIRIS-REx will have completed its primary mission. It will fire its engines to fly by Earth safely, putting it on a trajectory to circle the sun inside of Venus' orbit. After orbiting the Sun twice, the OSIRIS-REx spacecraft is due to reach Earth Sept. 24, 2023.
