Earth's scientists aren't content with just sending robotic adventurers to Mars to examine the local dirt. They want to investigate it up close and personal. 

NASA and the European Space Agency signed a letter of intent on Thursday to collaborate on a plan to bring Martian soil samples back to our planet. This is easier said than done. The ESA notes it would take several missions from Earth, plus a first-ever rocket launch from the surface of Mars.
