"Martian meteorites are pieces of Mars, basically they are our only samples of Mars on Earth until there is a sample return mission. Many of the discoveries we have made about Mars came from studying martian meteorites and wouldn't be possible without them. Unfortunately, these meteorites have all experienced shock from being ejected of the Martian surface during impacts."
"As far as life goes, our results are very favorable for the possibility - but we need more data. Really we need a sample return mission or we need to go there in person - a human mission. Science is closing in on the answers to a number of big questions about our solar system, life elsewhere, and Mars. But it is difficult work when it all has to be done from far away."
