Where is the OSIRIS-REx Spacecraft right now?

The app above shows the trajectory of the OSIRIS-REx Spacecraft and where it is right now. You can also wind the animation backwards in time to watch its launch and its flyby of the Earth before reaching the asteroid Bennu in 2018, and returning samples back to earth in 2023.

July 2018 - Successful Second Deep Space Maneuver for OSIRIS-REx Confirmed

New tracking data confirms that NASA’s OSIRIS-REx spacecraft successfully completed its second Deep Space Maneuver (DSM-2) on June 28. The DSM-2 burn, which employed the spacecraft’s Trajectory Correction Maneuver (TCM) thruster set, resulted in a 37 miles per hour (16.7 meters per second) change in the vehicle’s velocity and consumed 28.2 pounds (12.8 kilograms) of fuel.

DSM-2 was OSIRIS-REx’s last deep space maneuver of its outbound cruise to Bennu. The next engine burn, Asteroid Approach Maneuver 1 (AAM-1), is scheduled for early October. AAM-1 is a major braking maneuver designed to slow the spacecraft’s speed from approximately 1,130 to 320 miles per hour (506.2 to 144.4 meters per second) relative to Bennu and is the first of four asteroid approach maneuvers scheduled in order to accomplish arrival on 3rd December 2018.

OSIRIS-REx launched on 8th September 2016

OSIRIS-REx

This mission could help to save the world... quite literally! Bennu is a 500 meter wide asteroid that crosses earths orbit and has a low probablity (about 0.04%) of hitting the earth in the next 200 years. This mission allows this asteroid to be studied in great detail and will return samples of rock to Earth allowing better analysis than has ever been possible before. It will also allow a more accurate track of the asteroid to be determined so that we will have a better estimate of the chances of impact. Also knowing its structure will (hopefully) allow scientists to develop ways of changing its (or any similar objects) orbit to protect the Earth if necessary.

Here as some videos that explain this exciting mission:
