New mission, who dis? The spacecraft previously often called OSIRIS-REx had an impromptu shut encounter with the Solar because it follows a newly crafted path to a second asteroid, utilizing one among its photo voltaic arrays for shade.

It’s possible you’ll keep in mind NASA’s diligent spacecraft that snagged a pattern from an asteroid and dropped it off within the Utah desert in September 2023. That very same spacecraft is on a bonus mission to a unique asteroid, however as a way to get there, it’ll must fly 25 million miles nearer to the Solar than it was initially designed to do. On Tuesday, January 2, the mission, now often called OSIRIS-APEX, carried out the primary of six shut flybys of the Solar, coming to inside an unprecedented 46.5 million miles of our host star, exposing the spacecraft to a lot greater temperatures than it was meant to endure, NASA wrote in a weblog put up.
Tuesday’s flyby was the primary main take a look at for OSIRIS-APEX (quick for Origins, Spectral Interpretation, Useful resource Identification, and Safety–Apophis Explorer) because it heads towards its new goal: asteroid Apophis. Gizmodo reached out to NASA to verify in on the standing of the spacecraft following this primary photo voltaic flyby.
“NASA’s OSIRIS-APEX spacecraft continues to transmit a telemetry sign and function usually in its new configuration. As soon as OSIRIS-APEX is farther from the Solar in March, the mission crew will re-orient the spacecraft to level its high-gain antenna towards Earth to permit for high-speed communication,” a NASA spokesperson defined in an emailed January 4 assertion. “At that time, the crew will obtain and analyze telemetry knowledge to find out how the spacecraft carried out throughout its shut encounter with the Solar.”
When it was nonetheless OSIRIS-REx, the spacecraft had a few quarter of its gas left and its devices had been in nice situation because it departed from asteroid Bennu in Could 2021 with a pattern to ship, in keeping with NASA. That’s why the house company opted to ship the spacecraft on a brand new errand, exploring asteroid Apophis to watch bodily adjustments the house rock could endure from its shut encounter with Earth in April 2029. The asteroid will come to inside 20,000 miles (32,000 kilometers) of Earth’s floor, nearer than some high-altitude satellites (as an apart, Apophis was as soon as thought of a possible risk to Earth, however a 2021 remark marketing campaign concluded that there’s no danger of the asteroid impacting our planet for at the very least one other 100 years).

After dropping off the Bennu pattern, the spacecraft has to hold out shut passes to the Solar, in addition to three Earth gravity assists, to succeed in Apophis in 5 years. With the intention to shield OSIRIS-APEX from overheating throughout these shut encounters with our host star, engineers at Lockheed Martin (NASA’s mission companion) got here up with a intelligent spacecraft configuration. OSIRIS-APEX will preserve a hard and fast orientation with respect to the Solar whereas repositioning one among its photo voltaic arrays to shade the spacecraft’s most delicate parts whereas the second will stay prolonged to supply energy.
“We’ve executed plenty of modeling to make sure the spacecraft can be protected,” Dani Mendoza DellaGiustina, principal investigator for OSIRIS-APEX at College of Arizona, Tucson, stated in a press release. “However any time you are taking a chunk of house flight {hardware} past the design standards you incur danger.”
OSIRIS-APEX traveled properly contained in the orbit of Venus and was at round half the space between Earth and the Solar. Throughout that point, engineers turned off many of the spacecraft’s devices and communicated with it at low knowledge charges. When OSIRIS-APEX is farther from the Solar in March and April, engineers will flip the devices again on to check them.
The OSIRIS-REx spacecraft nailed its earlier mission, dropping off the dear cargo as deliberate. Since touchdown on Earth, nevertheless, engineers have been having hassle opening the canister containing the house rock samples.
