(CNN) Glaciers that still exist on the surface of Mars are helping to tell the story of its past. The red planet experienced between six and 20 separate ice ages during the past 300 to 800 million years, a new analysis of glaciers on Mars has revealed. During the last ice age on Earth 20,000 years ago, our planet was covered in glaciers. Those glaciers then retreated to the poles. These masses of ice left behind rocks as evidence, dropping them while scraping and carving paths as they moved to the poles.
SpaceX; Mark Brake/Getty Images; Business Insider Elon Musk said Tuesday he is "highly confident" SpaceX will land humans on Mars in 2026 — two years later than he previously hoped. In 2017, Musk said that he wanted SpaceX to send unmanned ships to Mars in 2022, followed by a crewed mission two years later. Musk told Axel Springer CEO Mathias Döpfner on Tuesday that he could make his own first trip to orbit in "possibly two or three years." Visit Business Insider's homepage for more stories.

A team of 7 volunteer 'astronauts' will take part in a simulation of a two-week-long mission to the surfaces of the Moon and Mars near the town of Pila, Poland in a project called the Poland Mars Analogue Simulation 2017, or PMAS 2017. The volunteers will stay inside the simulated space module until August 13, spending the first three days in 'lunar mode' before switching to prepare for the red planet.
