NASA’s Mars 2020 Will Blaze a Trail – for Humans

When a female astronaut first sets foot on the Moon in 2024, the historic moment will represent a step toward another NASA first: eventually putting humans on Mars. NASA’s latest robotic mission to the Red Planet, Mars 2020, aims to help future astronauts brave that inhospitable landscape.

While the science goal of the Mars 2020 rover is to look for signs of ancient life – it will be the first spacecraft to collect samples of the Martian surface, caching them in tubes that could be returned to Earth on a future mission – the vehicle also includes technology that paves the way for human exploration of Mars.

The atmosphere on Mars is mostly carbon dioxide and extremely thin (about 100 times less dense than Earth’s), with no breathable oxygen. There’s no water on the surface to drink, either. The landscape is freezing, with no protection from the Sun’s radiation or from passing dust storms. The keys to survival will be technology, research and testing.

Mars 2020 will help on all those fronts. When it launches in July of 2020, the spacecraft will carry the latest scientific and engineering tools, which are coming together as the rover is built at NASA’s Jet Propulsion Laboratory in Pasadena, California. Here’s a closer look:
