This composite of images taken by NASA’s Psyche mission shows the crescent of Mars grow as the spacecraft approached the planet for a gravity assist from May 2 to May 15, 2026. Because Psyche approached Mars from a high phase angle, the planet appeared as a thin crescent in the days running up to the […]
