Red Planet Day 2024: Red Planet Day is celebrated every year on November 28 to celebrate humanity’s enduring fascination with the “Red Planet”: Mars. The dusty, cold desert world has a very thin atmosphere above it. Not only does Mars have seasons, polar ice caps, canyons, and extinct volcanoes, but there is evidence that it was once more active; it is a vibrant planet. The day marks a key moment in the history of space exploration, commemorating the 1964 launch of NASA’s Mariner 4 spacecraft, the first mission to successfully send back close-up images of Mars. This day is a day to commemorate past achievements, reflect on the importance of Mars in scientific research, and inspire future exploration.

The history of Red Planet Day
The origins of Red Planet Day can be traced back to November 28, 1964, when NASA’s Mariner 4 spacecraft was launched on its historic journey to Mars. The mission marked humanity’s first detailed contact with the Red Planet, arriving in July 1965 and transmitting the first close-up images of its surface. The photos reveal a desolate, crater-filled landscape, dispelling early speculation about the canal and potential life.

looking for life
The search for extraterrestrial life remains at the heart of Mars exploration. Traces of water ice, organic molecules and methane spikes have sparked speculation about past microbial life. Red Planet Day encourages discussion of these findings and their implications.
The future of human exploration
Mars represents the next frontier in human space exploration. Organizations such as NASA, SpaceX and ESA envision a future colony on Mars, making it an important stepping stone to interstellar travel. Red Planet Day galvanizes public interest and support for these ambitious efforts.
interesting facts
- The first person to observe Mars through a telescope was Galileo Galilei. The planet’s name relates to its red appearance, derived from the Roman god.
- Because Mars is farther from the sun than Earth, Mars’ weather consists of extreme temperatures. Temperature range is -191 to +81 degrees Fahrenheit.
- The red planet’s gravity is about one-third that of Earth’s. Due to differences in gravity, a person who weighs 100 pounds on Earth only weighs about 38 pounds in space.
- Mars orbits much slower because it is so far from the sun. A “year” on Mars is about 687 days long, nearly twice as long as a year on Earth.
- There are no rings around Mars.
- Phobos and Deimos are the names of two satellites of Mars.
