NASA's Perseverance rover will collect samples that will be returned to Earth in 2031. Getting them back will require the most ambitious Mars missions in history and require sustained public support to succeed.

Mars Sample Return: An International Project to Bring Mars to Earth

Despite advances in space technology, certain science questions, including whether or not a Mars rock contains signs of ancient life, can only be answered in Earth-based laboratories.

Why did Perseverance, Tianwen-1, and Hope all launch around the same time?

Mars launches are scheduled when Earth and Mars are closest to each other, allowing mission planners to minimize the rocket energy required and maximize the weight of their spacecraft. It takes almost twice as long for Mars to orbit the Sun than Earth—365 days versus 687 days—which means Earth and Mars will be closest roughly every 2 years.

This was the first time 3 different countries have launched during the same opportunity. Launch periods differ for each mission, but typically last just a few weeks.
