 On 9 July 2013, the Mars 2020 Science Definition Team reiterated that the rover should look for signs of [[Life on Mars|past life]], collect samples for possible future return to Earth, and demonstrate technology for future human exploration of Mars.  The Science Definition Team proposed the rover collect and package as many as 31 samples of rock cores and soil for a later mission to bring back for more definitive analysis in laboratories on Earth, but in 2015 the concept was changed to collect even more samples and distribute the tubes in small piles across the surface of Mars. However, returning the samples to Earth would likely require two additional missions: one rover to land on Mars, take the samples collected by Mars 2020, and launch them into Mars orbit; and another to collect the sample canister in Mars orbit and return it to Earth. Neither of those missions is under development by NASA,
