Engineers confirm OSIRIS-APEX successfully completed its second of six close fly-bys of the Sun
Engineers have now confirmed that the asteroid probe OSIRIS-APEX successfully completed its second of six close fly-bys of the Sun in September, using its solar panels to shield its instruments from the Sun’s heat and light.
On Jan. 23 the mission team completed its review of all the data recorded by the spacecraft and its instruments during the solar pass [about 46 million miles from the Sun]. “There were no surprises, and the spacecraft is operating well,” said Mike Moreau, OSIRIS-APEX deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
As planned, on Sept. 2, 2024, OSIRIS-APEX passed through perihelion — the phase of its orbit closest to the Sun. The trajectory to Apophis takes the spacecraft much closer to the Sun than it was originally designed for. Between Aug. 1 and Oct. 13, the spacecraft was configured in a special orientation that uses one of the solar arrays to shade the most heat-sensitive components, keeping them within safe operating temperatures.
Because of the improvised orientation during the close approach, full data communications was not possible until months afterward. Only now have engineers completed their analysis.
OSIRIS-APEX original mission was to visit the asteroid Bennu and return samples from it to Earth. Once that mission was successfully completed, the probe was repurposed to go to the potentially dangerous asteroid Apophis when it makes its next close approach to the Earth in April 2029.
I have embedded below a short video showing the spacecraft’s journey to get to Apophis.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

Am I correct in believing that the mission was solely to study the asteroids? The close fly has no research regarding the sun?
jfm: You are correct. These fly-bys, which do not get within Mercury’s orbit, are solely to get the spacecraft to Apophis. And because the spacecraft was not designed to experience this environment, the goal is to protect its instruments, not do research.
