Videos & Animations


  • Down to the Core

    Design, build, and test a device that can take a core sample from a potato “asteroid,” “moon,” or “planet.” This activity uses a potato as the asteroid, but any object with a similar makeup/consistency can be used; you can also use different types of chocolate candies to drill into.

    Note: This activity is about drilling into an asteroid to collect a sample, unlike the OSIRIS-REx mission which “TAGged” the surface to collect its sample.

  • #MyOSIRISREx Pocket Spacecraft

    While the real OSIRIS-REx spacecraft is working to bring a sample of asteroid Bennu to Earth, you can take your own pocket spacecraft for an adventure right here at home. Snap a photo of your spacecraft TAG-ing something interesting where you live. Then share it by using the hashtag #MyOSIRISREx and tagging the NASA Solar System account on Twitter (@NASASolarSystem) or Instagram (@nasasolarsystem).

  • Make Your Own Asteroid

    Create your own unique asteroid using a few simple materials.

On October 20, 2020, the OSIRIS-REx spacecraft successfully touched the surface of the near-Earth asteroid Bennu and collected an abundant sample of the asteroid during the Touch-and-Go (TAG) sample collection event. The sampling event brought the spacecraft all the way down to sample site Nightingale, touching down within three feet (one meter) of the targeted location.

The process of actually selecting the sample site presented numerous challenges for scientists since Bennu is covered with large boulders.

Ever played the game of tag? Well, this is similar to how OSIRIS-REx was designed to grab a sample from Bennu!

Return to Earth

On May 10, 2021, NASA’s OSIRIS-REx spacecraft said farewell to asteroid Bennu and began its journey back to Earth. Before departing for Earth, the OSIRIS-REx spacecraft performed a final flyby of Bennu on April 7, 2021 – capturing its last images of sample collection site Nightingale to look for transformations on Bennu’s surface after the Oct. 20, 2020, sample collection event.

During sample collection, the spacecraft captured a substantial amount of material from Bennu’s surface, likely exceeding the mission’s requirement of 2 ounces (60 grams). The spacecraft is scheduled to deliver the sample to Earth on Sept. 24, 2023.


  • Researchers used precision-tracking data from NASA’s OSIRIS-REx spacecraft to better understand movements of the potentially hazardous asteroid Bennu through the year 2300, significantly reducing uncertainties related to its future orbit, and improving scientists’ ability to determine the total impact probability and predict orbits of other asteroids.

  • The mission engineers for OSIRIS-REx had planned to do a small thruster firing to ensure the spacecraft stays on the correct path back to Earth after its departure from asteroid Bennu. However, the May 10, 2021, departure maneuver was calculated and executed so precisely, the mission team didn’t require a clean-up maneuver.

  • Images taken during OSIRIS-REx’s final fly-over of asteroid Bennu on April 7, 2021, reveal the aftermath of its historic encounter with the asteroid.

  • On May 10, 2021, NASA’s OSIRIS-REx spacecraft departed near-Earth asteroid Bennu after being in orbit around the asteroid since December 2018. The spacecraft is carrying an abundance of rocks and dust it collected from Bennu, which it is scheduled to deliver to Earth on Sept. 24, 2023.

Other Resources

  • The Asteroid Watch Widget tracks asteroids and comets that will make relatively close approaches to Earth. The Widget displays the date of closest approach, approximate object diameter, relative size, and distance from Earth for each encounter.

  • Ever wondered where an asteroid, comet, or other small-body is located in our solar system? Look no further than this resource which allows you to type in the name of an object, and all the details you’d ever want to know about it will pop up (including an orbit diagram so that you can see where the object is relative to Earth)!

    NASA’s Solar System Treks

    The Solar System Treks are online, browser-based portals that allow you to visualize, explore, and analyze the surfaces of other worlds using real data returned from a growing fleet of spacecraft. You can view the worlds through the eyes of many different instruments, pilot real-time 3D flyovers above mountains and into craters, and conduct measurements of surface features.
