MARS

NASA’s Mars Atmosphere and Volatile Evolution Mission spacecraft completed 1,000 days in orbit around the red planet on June 17.

Elon Musk wrote a journal article in which he details his plans to send humans to Mars.

As Mars was changing from a comfortable planet with a thick atmosphere and lots of water into a dry and cold wasteland, these rocks captured evidence of those environmental changes.

If humans start a Mars colony and live there for generations, will their descendants ever be able to visit Earth? Not if they eat too many insects along the way.

NASA has unveiled a Mars rover concept that looks like the Batmobile and is built to dominate an alien planet.

The risk of astronauts developing cancer might be double what scientists have thought previously because the radiation in space and on Mars makes cells attack one another.

Ancient Mars could have had enough water to fill up a large ocean and many rivers flowing into it.

NASA has some exciting missions scheduled to launch over the next five years.

Data from NASA’s Curiosity rover showed conditions varying among different depths of the lake in Gale Crater on Mars that existed over three billion years ago.

Living in a colony on Mars sounds like it would be fun, but in reality it would be a terrible lifestyle, the head of the European Space Agency says.

We can’t say yes or no with certainty, but new findings made by NASA’s Curiosity rover extend the time frame in which life as we know it could have existed on the red planet.

These detailed photos of mars show how incredible the planet really is.

Humans settling Mars or living in a space colony might evolve into a new species much faster than they would have on Earth, assuming they can avoid the dangers of inbreeding.

NASA launched some student-designed Mars rover robots into space on a rocket to see how well they would travel in Earth’s atmosphere.

The sperm successfully created healthy offspring after surviving nine months on the International Space Station.

Elon Musk's SpaceX is working to send people to space, and eventually Mars. This is what they think it'll look like.

The rivers on Titan, Saturn’s biggest moon, flow across its landscape the way they used to on Mars before it dried up, so Titan may not be as similar to Earth as we thought.

The dwarf planet Ceres was in the perfect spot for NASA’s Dawn spacecraft to take shots of its bright surface and its even brighter crater.

A human space colony on Mars or another planet may evolve into a different race if we leave inhabitants alone to breed.

The atmosphere on Mars evolved over time, and during that period of climate change, rain probably fell hard enough in storms that carved out the surface and eroded craters.

Three billion years ago, Mars had conditions similar to those on Earth.
