NASA's Challenge: Transporting Mars Rocks to Earth.

NASA and the European Space Agency (ESA) are planning a complex and daring mission to bring back rock samples from Mars, collected by NASA's Perseverance rover. The mission, which could cost billions of dollars, involves launching a spacecraft to orbit Mars, landing on the planet's surface to collect the samples, and then returning them to Earth by 2033. However, technological and financial hurdles could derail the project, including the need for new inventions such as a rocket to launch from the Martian surface and miniature helicopters with claw-like grippers. The samples collected by Perseverance could shed light on Martian history and potentially contain evidence of past life on the planet.
