A study in Science Advances suggests that early large-scale collisions on Mars may have led to an underestimation of the planet's age. The Southwest Research Institute found that the tungsten content in Martian meteorites is highly varied, indicating that Mars formed rapidly in 2 to 4 million years. However, new models propose that Mars's formation involved significant collisions, creating a marbled mantle structure. This could mean Mars took 20 million years to fully form.
