About Red Planet Day

When is Red Planet Day? This holiday is always observed on November 28

Today is Red Planet Day, a November 28 holiday. The planet Mars is referred to as the “Red Planet” because it appears red. Red Planet Day honors our celestial neighbor, the fourth planet in the solar system.

It is sometimes called the “rusty planet”. The red color comes from the iron oxide (rust) that covers it. But, is Mars truly red in color? Scientists debated this question, even after the Mars Rovers landed and began to explore the planet. Why? Because the lenses used to take photos are tinted.

On Red Planet Day, take a few minutes to look upwards into the sky, and gaze at our neighbor. Hopefully, you will have a cloudless night sky for viewing. You can also recognize this day by reading up about Mars and viewing pictures of it. There are plenty of pictures online. NASA’s website is an excellent place to see high-quality pictures.

Red Planet Day commemorates the launch of the Spacecraft Mariner 4 on November 28, 1964. Mariner 4 was the first spacecraft to visit Mars. The 228-day mission of Mariner 4 brought the spacecraft within 6,118 miles of Mars on July 14, 1965.
