NASA’s Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer, or OSIRIS-REx for short, is the first spacecraft to return with an asteroid sample collection in ...

NASA's OSIRIS-APEX spacecraft fires its thrusters near the asteroid Apophis in this artist's illustration of the probe's extended mission after its OSIRIS-REx sample-return success on Sept. 24, 2023.

On Sunday, NASA’s OSIRIS-Rex mission will deliver a sample it collected from asteroid Bennu, completing a seven-year journey that could provide insights into how life originated on Earth.

Looking at OSIRIS-REx's target asteroid Bennu through telescopes, astronomers thought that it would be rather similar to other known space rocks. They were in for a surprise.

OSIRIS-REx’s next target, Apophis, also makes regular close approaches to Earth — but NASA has confirmed that this asteroid won’t be striking the planet on any of its next three approaches ...

Bennu, the asteroid from which OSIRIS-REx collected its sample, is thought to be made up of material that is around 4.5 billion years old, making it a potential time capsule from the earliest ...

In October 2020, Osiris-Rex pogo-sticked off the asteroid using its sampling tool, which looks like an automobile air filter at the end of a robotic arm, to pick up the rock samples.
