The images of the findings show flows lengthen and darken on rocky equator-facing slopes from late spring to early fall, and the seasonality, latitude distribution and brightness changes suggest a volatile material is involved, but there is no direct detection of one, NASA said.
The latest findings suggest signs of water in lower latitudes of Mars. Previously, it was known that water (in the form of ice) existed at the poles of the planet.
At one Martian crater, McEwen said, about a thousand ?water flows? were identified.
NASA said it will host a news briefing on Thursday about a significant new Mars science finding. The space agency did not give too many details in the release but said the new finding is based on observations from NASA's Mars Reconnaissance Orbiter (MRO), which has been orbiting the Red Planet since 2006.
The founder of Space Exploration Technologies Corp. (SpaceX) would like to see humans set up a colony on Mars in the next few decades.
Given that visitations of asteroids are always viewed with an element of fear and anxiety down here, how unsettling is the revelation that multiple asteroids of various sizes could be sharing our planet's orbital path?
Scientists have discovered first Trojan asteroid companion to Earth that orbits around the sun along with Earth for thousands of years.
Nicknamed 'Curiosity,' NASA's new Mars rover is being prepared to explore Gale Crater on Mars, with a mission to find answers to whether the environment could support and preserve life on Mars.
NASA has embraced a presidential directive to plant astronauts on an asteroid, a mission that officials say represents the most ambitious yet for the space agency.
NASA has chosen a landing site for its next Mars rover with the goal of seeking more signs of life and historical water on the planet. Scientists have long known that Mars is home to a few patches of carbonates -- minerals that form readily in large bodies of water -- but they suspect that many more carbonates may be hidden beneath layers of the Red planet.
Curiosity is planned to launch later this year and land in August 2012.
Mars Rover Curiosity will launch from earth in late 2011. By August 2012, it’s expected to land on Mars. Then, it’s expected to conduct a 2-year study of the red planet.
After careful deliberation, scientists have chosen the Gale crater as the landing site for the Mars rover Curiosity.
NASA moved on to a new chapter in space exploration on Friday, a day after the end of its shuttle program, by announcing details of plans to determine if Mars has or ever had the ingredients for life.
The Gale crater has been chosen as the landing site of the next Mars mission.
NASA has picked the Gale crater to be the landing site of the Mars rover Curiosity.
NASA discusses the latest Mars Rover and its plans to visit the red planet.
NASA has selected a destination for its latest Mars explorer, a car-sized probe named Curiosity, when the rover touches down on the red planet in August of 2012.
On this day in 1969, Astronaut Neil Armstrong was the first person to ever set foot on the moon.Armstrong was the commander of Apollo 11, where he was joined by Buzz Aldrin and command module pilot Michael Collins. Armstrong was 38 at the time.Apollo 11 landed on the surface of the moon at 8:17 pm on July 20, 1969 - less than a minute before they would have run out of fuel.After taking time to test the lunar surface for safety, Armstrong took man's first step on the moon - with 60...
NASA's Dawn spacecraft is set to begin a prolonged encounter with the asteroid Vesta on Friday, making the mission the first to enter orbit around a main-belt asteroid.
As the clock ticks down to this week's final space shuttle launch, there is a mounting sense of uncertainty about future U.S. dominance in space.
In his book NASA conspiracies British journalist and author Nick Redfern has raised many questions on the space agency efforts in exploring outer space, including the Apollo moon landings, the controversial face on Mars, UFO sightings and other secret space programs.
