NASA has thrown a lifeline to scientists working on a mission to visit an asteroid that will make an unusually close flyby of the Earth in 2029, reversing the Trump administration's previous plan to shut it down.
This mission, named OSIRIS-APEX, was one of 19 operating NASA science missions the White House proposed canceling in a budget blueprint released earlier this year.
"We were called for cancellation as part to the president's budget request, and we were reinstated and given a plan to move ahead in FY26 (Fiscal Year 2026) just two weeks ago," said Dani DellaGiustina, principal investigator for OSIRIS-APEX at the University of Arizona. "Our spacecraft appears happy and healthy."
OSIRIS-APEX repurposes the spacecraft from NASA's OSIRIS-REx asteroid sample return mission, which deposited its extraterrestrial treasure back on Earth in 2023. The spacecraft was in good shape and still had plenty of fuel, so NASA decided to send it to explore another asteroid, named Apophis, due to pass about 20,000 miles (32,000 kilometers) from the Earth on April 13, 2029.
The flyby of Apophis offers scientists a golden opportunity to see a potential killer asteroid up-close. Apophis has a lumpy shape with an average diameter of about 1,100 feet (340 meters), large enough to cause regional devastation if it impacted the Earth. The asteroid has no chance of striking us in 2029 or any other time for the next century, but it routinely crosses the Earth's path as it circles the Sun, so the long-term risk is non-zero.
It pays to be specific
Everything was going well with OSIRIS-APEX until May, when White House officials signaled their intention to terminate the mission. The Trump administration's proposed cancellation of 19 of NASA's operating missions was part of a nearly 50 percent cut to the agency's science budget in the White House budget request for fiscal year 2026, which began October 1.
Lawmakers in the House and Senate have moved to reject nearly all of the science cuts, with the Senate bill maintaining funding for NASA's science division at $7.3 billion, the same as fiscal year 2025, while the House bill reduces it to $6 billion, still significantly more than the $3.9 billion for science in the White House budget proposal.
