GoKawiilA common road trip activity is stopping at a roadside attraction to see something really cool. It turns out that NASA spacecraft do this from time to time as well. The Psyche spacecraft, on its way to the asteroid belt to study its namesake asteroid, made a stop by Mars and, among other things, took some pretty epic pictures of the planet as it flew by.
The flyby occurred on May 15, with the idea that Psyche would use Mars as a gravitational slingshot to change the spacecraft’s direction and send it on its merry way. However, NASA rarely lets opportunities like this slip through its fingers, so while Psyche was flying by Mars, NASA had the spacecraft measure the red planet with every tool that Psyche had onboard, capturing all sorts of data and several breathtaking images.
The big winner is a series of time-lapse images taken daily by the spacecraft as it approached Mars, which were then stitched together. The final image forms an eye-like shape, making it unique thanks to the angle at which Pscyhe approached Mars. The spacecraft didn’t stop there and took a month-long time-lapse of the planet as it flew by.
“Coming in at such a high phase crescent, only about 4% of Mars was illuminated, and with that, we could see the atmosphere around it glowing,” said Hannah Zigo of Psyche’s multispectral imager operations team at Arizona State University in a YouTube video.
Psyche’s imaging team captured a time-lapse of Psyche passing by Mars, from May 2 to May 31, when the planet was no longer visible. They also released a time-lapse video that condenses this month-long flyby into 1 minute and 15 seconds of some of the best imagery you’ll ever see of our red neighbor from space.

Other science happened, too
NASA’s spacecraft took as much data as it could during its brief flyby, and measured everything from Mars’ atmosphere reacting to solar winds to neutrons bombarding the red planet’s surface, thanks to its thin atmosphere. Psyche’s instruments weren’t necessarily tuned for measuring a planet, but Mars made for an excellent test bed for the spacecraft’s various tools.
“The mission’s imager, magnetometer and gamma-ray and neutron spectrometer teams worked overtime to make full use of this planetary encounter, and all instruments delivered great results,” said Lindy Elkins-Tanton, principal investigator for Psyche at the University of California, Berkeley, in a statement.
