28 November is observed as Red Planet Day, a day that honors the 1964 launch of NASA’s Mariner 4 mission—the first spacecraft to successfully perform a close-range flyby of Mars and transmit detailed images of the Martian surface back to Earth. The day highlights a major milestone in space exploration and humanity’s early steps toward understanding the Red Planet. Additionally, in many countries around the world, 28 November also aligns with Black Friday, the major post-Thanksgiving shopping event originating in the United States. It has become one of the year’s biggest retail occasions globally, marked by massive discounts, heavy consumer footfall, and online sales across various industries.
