On New Year’s Day, NASA’s Parker Solar Probe added to the festive cheer by sending dwelling extra excellent news about its record-breaking closest-ever method to the solar.
On Wednesday (Jan. 1), mission management at Johns Hopkins University’s Applied Physics Laboratory in Maryland started receiving the Parker Solar Probe’s first telemetry — or housekeeping knowledge — that confirms Parker’s methods and science devices are “wholesome and working usually” after its historic rendezvous with the solar, NASA shared in an replace on Thursday (Jan. 2).
“All is wanting good with the spacecraft methods and instrument operations,” Michael Buckley, a spokesperson at JHUAPL, which oversees the Parker Solar Probe mission, advised Space.com in an e-mail. “It actually is a exceptional spacecraft!”
The newest telemetry transmission additionally confirms the Parker Solar Probe efficiently carried out the instructions programmed into its flight computer systems and that its science devices have been functioning through the flyby, based on the assertion. That means the spacecraft collected helpful knowledge about our star because it swooped to inside 3.8 million miles (6.1 million kilometers) of the solar’s floor — the closest but a spacecraft has ever gotten to our star.
“While Parker Solar Probe was nearer to the solar than some other human-made object in historical past, it operated simply because it was designed to do, and made observations that nobody has been capable of make earlier than,” Helene Winters, this system supervisor for the Parker Solar Probe mission at JHUAPL, mentioned within the assertion.
The telemetry transmission, which mission management is receiving by means of NASA’s Deep Space Network, continues by means of Thursday, Buckley mentioned. The probe ought to beam dwelling its collected science knowledge later this month, when its strongest onboard antenna will probably be in higher alignment with Earth to transmit at greater charges.
“The knowledge that may come down from the spacecraft will probably be recent details about a spot that we, as humanity, have by no means been,” Joe Westlake, the director of the Heliophysics Division at NASA Headquarters in Washington, mentioned in a Dec. 27 replace. “It’s an incredible accomplishment.”
On Christmas Eve, the Parker Solar Probe hurtled by means of the scorching photo voltaic environment whereas touring at a most pace of 430,000 miles per hour (690,000 kilometers per hour) — quick sufficient to journey from Tokyo to Washington, D.C. inside a minute — breaking its personal report because the quickest object ever constructed.
Scientists have been out of contact with the probe through the rendezvous, and simply earlier than midnight on Dec. 26, they acquired a easy but much-anticipated beacon tone indicating the spacecraft survived the encounter and is working usually. Thanks to a customized, 4.5-inch-thick (11.4-centimeter-thick) warmth defend, the spacecraft may efficiently endure temperatures as much as 1,800 levels Fahrenheit (982 levels Celsius), NASA beforehand mentioned.

Scientists hope knowledge from Parker will assist them decode longstanding mysteries about our solar, resembling why its tenuous outer environment, the corona, will get a whole bunch of occasions hotter the farther it stretches from the solar’s floor.
“The knowledge is so necessary for the science neighborhood as a result of it offers us one other vantage level,” Kelly Korreck, a heliophysicist at NASA Headquarters who labored on one of many mission’s devices, mentioned within the assertion. “By getting firsthand accounts of what is taking place within the photo voltaic environment, Parker Solar Probe has revolutionized our understanding of the solar.”
The spacecraft is scheduled for 2 extra flybys in 2025 at roughly the identical pace and distance from the solar — on March 22 and June 19.
