NASA's Psyche spacecraft documented Mars's crescent phase expanding as it performed a gravity assist maneuver near the Red Planet.
NASA's Psyche mission has provided a unique visual record of Mars, capturing the planet's appearance as a growing crescent shape. These images were acquired by the spacecraft's multispectral imager between May 2 and May 15, 2026, during its approach for a gravity assist.
The sequence begins with Mars appearing as a small crescent when the spacecraft was at its furthest point. As Psyche drew closer, the illuminated portion of Mars visible to the spacecraft progressively increased, showing the planet transitioning from a sliver to a fuller disc.
The spacecraft observed Mars from a high phase angle, meaning the sun illuminated Mars from the side relative to Psyche's viewpoint. This perspective caused the planet to appear as a thin crescent during the approach.
Following these initial observations, Mars eventually filled the imager's field of view as Psyche executed its close approach. The mission team has compiled these views, encompassing the approach, close encounter, and departure, into a time-lapse compilation of the entire Mars flyby.
The Psyche mission's multispectral imager, by capturing Mars's evolving crescent during a gravity assist, demonstrates the sophisticated optical capabilities being deployed for deep space navigation and observation. This ability to precisely track planetary bodies from varying perspectives is foundational for complex orbital maneuvers. As we expand humanity's presence beyond Earth, such instruments will be critical for mapping, reconnaissance, and establishing infrastructure on Mars, enabling us to better understand and inhabit our new celestial home and accelerating our journey towards a self-sustaining interplanetary civilization.
