Have you ever wondered about the cosmic ballet performed by spacecraft as they journey through our solar system? Imagine this: a probe launched from Earth, travelling millions of miles to an asteroid, delicately collecting samples, and then returning home. That’s the incredible story of OSIRIS-REx, a mission that captivated the world. But just how far did this intrepid explorer travel during its daring adventure?
A Journey of Epic Proportions
OSIRIS-REx, short for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer, wasn’t just a mouthful of a mission name, it was a journey of epic proportions. Its target: the near-Earth asteroid Bennu. But reaching Bennu, which orbits the sun between Earth and Mars, was no simple task. It involved a carefully choreographed dance through the cosmos.
To Bennu and Beyond
Launched in 2016, OSIRIS-REx spent two years catching up with Bennu, finally arriving at the asteroid in 2018. But the journey wasn’t a straight line. To match Bennu’s speed and trajectory, the spacecraft used Earth’s gravity as a slingshot, performing a close flyby of our planet in 2017.
Think of it like throwing a paper airplane. With a good throw, it glides through the air. But with a flick of your wrist and the right angle, you can use the air itself to help it travel further. That’s essentially what OSIRIS-REx did, using Earth’s gravity to alter its path and propel it towards Bennu.
A Round Trip for Science
After spending over two years studying Bennu and successfully collecting a sample, OSIRIS-REx began its return journey in 2021. Once again, the journey wasn’t direct. The spacecraft had to navigate the gravitational pull of the sun and other planets, making tiny adjustments to ensure it reached Earth safely.
Finally, in September 2023, OSIRIS-REx released its precious cargo – a capsule containing pieces of Bennu – which landed safely in the Utah desert.
So, How Many Miles Did OSIRIS-REx Travel?
In total, OSIRIS-REx traveled approximately 4.2 billion miles (6.72 billion kilometers) during its seven-year mission. That’s equivalent to driving around Earth’s equator over 168,000 times!
OSIRIS-REx and Earth
This incredible journey highlights the challenges and triumphs of space exploration. OSIRIS-REx’s mission is a testament to human ingenuity and our relentless thirst for knowledge about our solar system and beyond.
FAQs About OSIRIS-REx’s Journey
Why did OSIRIS-REx go to Bennu? Scientists believe that Bennu is a “time capsule” from the early solar system, and studying its composition could help us understand the formation of planets and even the origins of life on Earth.
What will happen to the OSIRIS-REx spacecraft now? After releasing its sample capsule, the spacecraft embarked on a new mission to study the near-Earth asteroid Apophis.

Traveling Here on Earth
While most of us won’t have the opportunity to travel billions of miles through space, we can still explore the wonders of our own planet.
Think about a scenic road trip along the Pacific Coast Highway, where the vastness of the ocean mirrors the enormity of space. Or perhaps a train ride through the Swiss Alps, where the towering peaks remind us of the grand scale of the universe.
OSIRIS-REx at Bennu
No matter where your travels take you, remember that even here on Earth, there’s always something new to discover. And who knows, maybe one day, you’ll be inspired to embark on your own exploration, just like OSIRIS-REx.
