NASA’s Psyche Spacecraft Gifts Us Stunning Mars Snapshots

It’s a bit like taking a scenic detour on a road trip—except the road is interplanetary space and the car is a multi‑million‑dollar spacecraft. NASA’s Psyche probe, on its way to the metal‑rich asteroid 16 Psyche, decided to swing by Mars on May 15, 2024, using the planet’s gravity like a cosmic slingshot.

Rather than simply zip past, mission engineers cranked up every instrument on board, hoping to squeeze a little extra science out of the brief encounter. What they got was a series of breathtaking images and a trove of data that will keep researchers busy for months.

The most eye‑catching product is a time‑lapse mosaic stitched from daily frames taken as Psyche closed in on the Red Planet. The final composite looks almost like an eye—thanks to the unusual angle of approach and the fact that only about 4 % of Mars was illuminated by a thin crescent of sunlight. That faint glow, a halo of atmospheric scattering, is visible around the planet’s rim, offering a rare glimpse of Mars’s tenuous atmosphere interacting with solar radiation.

“Coming in at such a high phase crescent, we could see the atmosphere around it glowing,” explained Hannah Zigo of the multispectral imager team in a YouTube briefing. The team also compiled a one‑minute‑fifteen‑second video that condenses the entire month‑long flyby—from May 2 to May 31—into a fast‑moving, almost cinematic sequence.

But the picture‑taking wasn’t just for show. Psyche’s magnetometer, gamma‑ray, and neutron spectrometers were busy measuring how solar wind particles interact with the thin Martian atmosphere and surface. Those readings, while not groundbreaking (Mars has been studied for decades), serve as a valuable calibration check for the instruments that will soon be probing the metallic asteroid.

“All instruments delivered great results,” said mission PI Lindy Elkins‑Tanton of UC Berkeley. The imager, however, stole the spotlight. Jim Bell, the imager lead at Arizona State University, noted that the camera not only captured stunning views but also successfully resolved the tiny moons Phobos and Deimos from a great distance—essential practice for searching for possible moonlets around asteroid Psyche.

For anyone sitting at a desk on Earth, the payoff is simple: a handful of spectacular desktop‑background candidates and a fresh reminder of how beautiful—and dynamic—our neighbor really is. Psyche will continue its voyage, aiming to rendezvous with asteroid 16 Psyche in August 2029, armed with fully tested instruments and a few extra Martian memories.
