MARS

Three objects slammed into Mars at the same time to create this unusual crater.

If there are aliens or fossils of previous extraterrestrials on Mars, scientists are going to have to know where to look. That’s where this Earth desert and its bacteria tenants come in.

We may soon know for sure whether extraterrestrial life ever existed in other places within our solar system, but don’t expect to shake hands with an alien any time soon.

A long-destroyed planet is haunting Mars, with its remains following Earth’s neighbor wherever it goes.

A fleet of robots that could one day travel to other planets and moons looking for aliens are packed with tools like buzzsaws and catapults.

NASA reveals plan to build a Deep Space Gateway near the lunar surface to serve as a pit stop for astronauts going to Mars.

Scientists think they’ve figured out exactly how much air the Sun has sucked off of Mars, turning it from a warm and wet planet into a red wasteland.

While you wait for an opportunity to travel to Mars, check out these places right here on Earth that are similar to our space neighbor.

The spacecraft began studying Mars from an orbital perspective in 2006, and images taken from its Context Camera now cover over 99 percent of the red planet.

The ExoMars rover and surface platform will, in 2021, land in either Oxia Planum or Mawrth Vallis — both located in the northern hemisphere of the red planet.

A Norwegian mathematics expert may have just discovered how humans will one day travel to Mars in just three minutes.

In a study published in the Journal of Geophysical Research Planets, a team of scientists has identified a crater that they say was created by an asteroid that triggered one such event.

The images were captured using the High Resolution Imaging Science Experiment camera on board NASA's Mars Reconnaissance Orbiter.

President Trump signed the NASA Authorization Act on Tuesday, but SpaceX founder Elon Musk doesn't believe the bill will do much for the future of space exploration, including trips to Mars.

The damage, which NASA said was an expected part of the wheel’s life cycle, was discovered during a routine check carried out earlier this month.

This cute little robot can squeeze into tight spaces and get over some rough terrain on Mars, so it might go as a helper to the rover.

Volcanic activity in Arsia Mons — the southernmost member of the Tharsis Montes group — most likely peaked roughly 150 million years ago.

A new model suggests that Mars' moons — Phobos and Deimos — may be the product of rings of debris coalescing and breaking apart many times over the past 4.3 billion years.

The universe is enormous and diverse, so there is potential for life on other planets near and far. Scientists look for these conditions when they search for aliens.

"I don't want to be remembered for just kicking moon dust," he told USA Today.

“The concept is simple: transport astronauts from Earth to a Mars-orbiting science laboratory."
