    How NASA Will Use Robots to Create Rocket Fuel From Martian Soil

    The year is 2038. After 18 months living and working on the surface of Mars, a crew of six explorers boards a deep-space transport rocket and leaves for Earth. No humans are staying behind, but work goes on without them: Autonomous robots will keep running a mining and chemical-synthesis plant they’d started years before this first crewed mission ever set foot on the planet. The plant produces water, oxygen, and rocket fuel using local resources, and it will methodically build up all the necessary supplies for the next Mars mission, set to arrive in another two years.

But the chilly temperatures and the presence of six-ton shaggy beasts with extremely long tusks would confirm you really were in the Pleistocene epoch, otherwise known as the Ice Age. You’d be visiting the mammoth steppe, an environment that stretched from Spain across Eurasia and the Bering Strait to Canada.
