Concept for a Mars base, with ice home, pressurized rover, and Mars suits, 2016. The idea of sending humans to Mars has been the subject of aerospace engineering and scientific studies since the late 1940s as part of the broader exploration of Mars. [1] Long-term proposals have included sending settlers and terraforming the planet.
Extra-close oppositions of Mars happen every 15 to 17 years, when we pass between Mars and the Sun around the time of its perihelion (closest point to the Sun in orbit). The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost ...
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
The trip is expected to take nine months to a year with stops along the way to study the local terrain. [94] [95] [96] On 16 July 2013, the Curiosity rover reached a milestone in its journey across Mars, having traveled 1 km (0.62 mi), since its landing in 2012; [97] on 1 August 2013, the rover traveled over one mile: 1.686 km (1.048 mi).

The company is one of NASA's largest contractors and is one of several currently working on projects related to Mars. So far, only unmanned rovers and orbiters have made it to the Red Planet. When ...
Based on these measurements, for a round trip Mars surface mission with 180 days (each way) cruise, and 500 days on the Martian surface for this current solar cycle, an astronaut would be exposed to a total mission dose equivalent of ~1.01 sievert. Exposure to one sievert is associated with a five percent increase in risk for developing fatal ...
A collection of Martian rocks could reveal details about potential past life on the Red Planet – but first NASA has to get them back to Earth.. For years, the U.S. space agency's Perseverance ...
The prospect of leaving Earth for good does not scare Alex (Kyle Allen). Instead, it inspires him. It’s not that he doesn’t cherish his mother, his father and his sister. They’re as close as ...
