NASA’s OSIRIS-REx mission is set to return the first U.S. asteroid sample to Earth in September after a successful mockup drop test in Utah’s West Desert.
A team led by NASA in Utah’s West Desert is in the final stages of preparing for the arrival of the first U.S. asteroid sample – slated to land on Earth in this month.
A mockup of NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer) sample capsule was dropped last Wednesday from an aircraft and landed at the drop zone at the Department of Defense’s Utah Test and Training Range in the desert outside Salt Lake City. This was part of the mission’s final major test prior to the arrival of the actual capsule on September 24 with its sample of asteroid Bennu, collected in space almost three years ago.
“We are now mere weeks away from receiving a piece of solar system history on Earth, and this successful drop test ensures we’re ready,” said Nicola Fox, associate administrator of NASA’s Science Mission Directorate in Washington. “Pristine material from asteroid Bennu will help shed light on the formation of our solar system 4.5 billion years ago, and perhaps even on how life on Earth began.”
Rehearsals and Anticipation
This drop test follows a series of earlier rehearsals – capsule recovery, spacecraft engineering operations, and sample curation procedures – conducted earlier this spring and summer.
Now, with less than four weeks until the spacecraft’s arrival, the OSIRIS-REx team is nearing the end of rehearsals and ready for the actual delivery.
“I am immensely proud of the efforts our team has poured into this endeavor,” said Dante Lauretta, principal investigator for OSIRIS-REx at the University of Arizona, Tucson. “Just as our meticulous planning and rehearsal prepared us to collect a sample from Bennu, we have honed our skills for sample recovery.”
The capsule is carrying an estimated 8.8 ounces of rocky material collected from the surface of the asteroid Bennu in 2020. Researchers will study the sample in the coming years to learn about how our planet and solar system formed, as well as the origin of organics that may have led to life on Earth.
OSIRIS-REx is NASA’s first asteroid sample return mission. It launched in September 2016 on a journey to explore a near-Earth asteroid called Bennu.

Capsule’s Arrival and Further Processing
The capsule will enter Earth’s atmosphere at 10:42 a.m. EDT (8:42 a.m. MDT), traveling about 27,650 mph. NASA’s live coverage of the capsule landing starts at 10 a.m. EDT (8 a.m. MDT), and will air on NASA TV, the NASA app, and the agency’s website.
“We are now in the final leg of this seven-year journey, and it feels very much like the last few miles of a marathon, with a confluence of emotions like pride and joy coexisting with a determined focus to complete the race well,” said Rich Burns, project manager for OSIRIS-REx at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
Once located and packaged for travel, the capsule will be flown to a temporary clean room on the military range, where it will undergo initial processing and disassembly in preparation for its journey by aircraft to NASA’s Johnson Space Center in Houston, where the sample will be documented, cared for, and distributed for analysis to scientists worldwide.
Collaborators and Partnerships
NASA’s Goddard Space Flight Center in Maryland is responsible for overall mission management, systems engineering, and ensuring safety and mission assurance for OSIRIS-REx. The University of Arizona, Tucson, headed by Dante Lauretta, is the chief investigator, guiding the science team, science observation planning, and data processing. Lockheed Martin Space constructed the spacecraft and manages flight operations, while Goddard and KinetX Aerospace navigate the OSIRIS-REx spacecraft. Sample curation for the mission, including processing the sample upon Earth arrival, is designated to NASA’s Johnson Space Center in Houston. The mission also boasts international collaboration, featuring instruments from the Canadian Space Agency and sample science collaboration with Japan’s Hayabusa2 mission. OSIRIS-REx is a significant mission under NASA’s New Frontiers Program, overseen by NASA’s Marshall Space Flight Center in Alabama.

A great accomplishment of obtaining samples for inspection. What is really on my mind is the resent observation of the asteroid Dimorphous and why it is increasing in orbital period after a decrease in the orbital period of the impact, the Dart Having made a expansion bubble at impact the collapse of vacuum of space has crated a greater kinetic push on the asteroid increasing the orbital period.
