Mars sample return – bringing rocks from Mars back to Earth – has been on NASA’s wish list for decades, and work is underway to develop the necessary technology. Recently a group of scientists field-tested a robotic system that can drill into rocks, collect small core samples and store them for later retrieval. The field test included members of the NASAJPL robotics team that developed the coring and caching system, and scientists from AMASE, a NASA-funded group that has explored Mars-analog sites on the Arctic island of Svalbard.
