OSIRIS-REx
Asteroid Bennu, Sample Return and Planetary Defense
OSIRIS-REx is a mission story that lets users explore OSIRIS-REx, the asteroid sample-return mission that visited Bennu and brought material back to Earth.
Mission
Learn how OSIRIS-REx connects asteroids, sample return, small-body navigation, and the science of early Solar System material.
Object type
Sample-return spacecraft
Target / region
Asteroid Bennu
Known for
Returning asteroid material to Earth

OSIRIS-REx connects asteroid tracking, sample return, orbital operations around small bodies, and planetary defense awareness
Why this mission belongs in the Library
Learn how OSIRIS-REx connects asteroids, sample return, small-body navigation, and the science of early Solar System material.
The story
A mission to collect ancient material
OSIRIS-REx is part of the TransitSatellite mission Library because it gives users a concrete example of how spacecraft are designed for a specific target, environment, and science goal.
The mission is known for returning a sample from asteroid bennu, which makes it a strong connecting page between the Solar System map, Library stories, and future education content.
Mission design
Operating near an asteroid
Every mission has a path. For OSIRIS-REx, the route, timing, instruments, and operating environment all shape what the spacecraft can accomplish.
That makes this story useful for explaining that spaceflight is not only about reaching a destination. It is also about choosing the right orbit, flyby path, landing plan, communication method, or observing location.
Why it matters
Bringing part of space home
As a asteroid sample-return mission, OSIRIS-REx helps show how different mission types answer different questions.
Some missions orbit, some land, some fly past, some return samples, and some observe from carefully chosen places in space.
TransitSatellite connection
Asteroids belong in the tracking story
OSIRIS-REx connects asteroid tracking, sample return, orbital operations around small bodies, and planetary defense awareness.
In the TransitSatellite Library, OSIRIS-REx helps create a connected trail from satellites and planets into mission planning, engineering, science, and the wider space story.
