Mariner 4 was a historic NASA mission that in 1965 became the first spacecraft to conduct a successful flyby of Mars, capturing the first close-up images of the planet and revealing a cold, cratered, and Moon-like surface with a thin atmosphere and no signs of life or canals. The mission provided essential data on interplanetary space conditions and radiation, paving the way for future deep space exploration and demonstrating the feasibility of long-duration space flights. This partch commemorates the mission with the Mariner 4 probe passing over the planet Mars. Patch is 4" in diameter and is in stock.
