NASA and an international team of planetary scientists have found evidence in meteorites on Earth that indicates Mars has a distinct and global reservoir of water or ice near its surface.

The team responsible for the Sample Analysis at Mars (SAM) instrument suite on NASA's Curiosity rover has made the first definitive detection of organic molecules at Mars.

This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows dramatic buttes and layers on the lower flank of Mount Sharp.

How Water Helped Shape Mars' Landscape

Observations by NASA's Curiosity Rover indicate Mars' Mount Sharp was built by sediments deposited in a large lake bed over tens of millions of years.

Mars: To Boldly Stay

NASA astrobiologist Chris McKay studies the most extreme parts of Earth to understand how life might survive in other perts of the universe. But he's also studying another life form living in space: humans.

The team of Western University space explorers investigating the surface of Mars with the largest telescope ever used for a deep space mission released its first two images today.

Infographic: NASA's Journey to Mars

NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010.

Mars, Like Earth, Has Macroweather

Weather, which changes day-to-day due to constant fluctuations in the atmosphere, and climate, which varies over decades, are familiar.

A NASA media briefing on Nov. 6 at Kennedy Space Center highlighted the fully assembled Orion spacecraft and details of its first test flight, scheduled for Dec. 4.

Two NASA and one European spacecraft that obtained the first up-close observations of a comet flyby of Mars on Oct. 19, have gathered new information about the basic properties of the comet's nucleus and directly detected the effects on the Martian atmosphere.

Reddish rock powder from the first hole drilled into a Martian mountain by NASA's Curiosity rover has yielded the mission's first confirmation of a mineral mapped from orbit.

Chaos in Atlantis Basin on Mars

Mars is peppered with craters. Scientists have deduced that the red planet is struck by around 200 meteoroids every year that dig out new craters.

Several Mars-based NASA spacecraft had prime viewing positions for comet Siding Spring's October 19 close flyby of the Red Planet. Early images included a composite photo from NASA's Hubble Space Telescope that combined shots of Mars, the comet, and a star background to illustrate Siding Spring's distance from Mars at closest approach.

Comet Siding Spring Seen Next to Mars

This composite NASA Hubble Space Telescope Image captures the positions of comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT October 19, 2014. The comet passed by Mars at approximately 87,000 miles (about one-third of the distance between Earth and the Moon). At that time, the comet and Mars were approximately 149 million miles from Earth.

Humans have long dreamed of traveling to Mars, hopscotching across the solar system and fanning out into the cosmos beyond.

Opportunity Views Comet Near Mars

Mars Exploration Rover Opportunity captured images of a comet passing much closer to Mars than any previous known comet flyby of Earth or Mars. The images of comet Siding Spring were taken against a backdrop of the pre-dawn Martian sky on Sunday (Oct. 19).

All three NASA orbiters around Mars confirmed their healthy status Sunday after each took shelter behind Mars during a period of risk from dust released by a passing comet.

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars.

The Look of a Young Mars

This artist's concept depicts the early Martian environment (left) - believed to contain liquid water and a thicker atmosphere - versus the cold, dry environment seen at Mars today (right).

New Image From Mars Orbiter
