The spacecraft, which is on its way to an asteroid also called Psyche, will come within around 2,800 miles (4,500 kilometers) of the Red Planet during the flyby. The aim of this flyby is to utilize the gravity of Mars to give Psyche a boost to its already impressive speed of 12,333 miles per hour (19,848 kph). This will enable the spacecraft to adjust its trajectory towards the 173-mile-wide (280 km) metal-rich asteroid 16 Psyche, (or just Psyche) which sits in the main asteroid belt between Mars and Jupiter.The Psyche spacecraft, which launched in October 2023, is expected to reach its target namesake asteroid in 2029, offering scientists an opportunity to study a very unique object. 16 Psyche is thought to be an early solar system planetesimal, a body from which planets formed, that has had its outer layers stripped away by billions of years of collisions. Thus, its exposed nickel-iron core represents a rare chance to study the usually hidden cores of rocky planets.Mars as seen by NASA’s Psyche asteroid probe on May 3, 2026. | Credit: NASA/JPL-Caltech/ASUBut the Psyche spacecraft won’t just use the gravity of Mars to get a boost that will help it save its xenon gas propellant; the Red Planet flyby will also offer Psyche a chance to test and calibrate the instruments it will be using when it gets to the main asteroid belt.In order to do that, Psyche’s multispectral imager will be used to capture thousands of observations of Mars. This process began earlier this month.AdvertisementAdvertisementPsyche’s operators first began prepping the spacecraft’s Mars encounter by performing a trajectory correction maneuver on Feb. 23. This involved firing the spacecraft’s thrusters for 12 hours, increasing Psyche’s speed, and refining its approach to the Red Planet.”We are now exactly on target for the flyby, and we’ve programmed the flight computer with everything that the spacecraft will do throughout May,” Sarah Bairstow, Psyche’s mission planning lead at NASA’s Jet Propulsion Laboratory in Southern California, said in a NASA statement. “This is our first opportunity in flight to calibrate Psyche’s imager with something bigger than a few pixels, and we’ll also make observations with the mission’s other science instruments.”This image of Mars was captured by NASA’s Psyche mission on May 3, 2026, about 3 million miles (4.8 million km) from the planet as the spacecraft approaches for a gravity assist on May 15. | Credit: NASA/JPL-Caltech/ASUThe team thinks that the Psyche probe may observe a faint dusty ring, or torus, …
