Mars is the fourth planet from the Sun and the second smallest planet in the Solar System. Named after the Roman god of war, it is often described as the "Red Planet", as the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the second highest known mountain within the Solar System (the tallest on a planet), and of Valles Marineris, one of the largest canyons. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Martian trojan asteroid. Read more on wikipedia
A Canadian-led team of researchers have discovered bacteria that can grow in Canadian High Arctic much below the freezing point, and this makes the recent discovery of a bacterium that is able to grow at -15 degrees C one the coldest temperature ever reported for bacterial growth, as exciting.
The U.S. House Subcommittee on Space held one of their hearings today on the topic of possible options for the next steps in human space flight and how these options move the U.S. closer to a human mission to Mars and beyond.
NASA is onboard for creating a 3D printer--for food. What sort of food will it print, you ask? Apparently the first item on the menu is pizza.
NASA's Mars rover Curiosity, the vehicle that's trekking across the Red Planet in hopes of making novel discoveries, has officially drilled into its second rock. The sample, once analyzed by the rover's onboard laboratory, could reveal new insight into the origins of Mars.
A rover has been making its way across the surface of Mars for nine years, steadily recording data during its lone trek. Now, Mars Exploration Rover (MER) Opportunity has broken a record. It's travelled the farthest of any extraterrestrial vehicle.
Mars is making less of an impact--at least as far as its craters are concerned. Scientists have discovered that space rocks are smashing into the Red Planet far less frequently than once thought.
Could we really farm on Mars? NASA is looking into the possibility of growing plants on the Red Planet in order to create a self-sustaining Mars colony.
NASA's Mars rover Curiosity has a new site to drill--the Cumberland rock. Now, the rover will set course for the location in the coming day.
Ever wanted to take a trip to Mars? Now, you can--as long as you don't mind the fact that it's a one-way ticket and you'd never see Earth again.
Weather forecasts may soon come to Mars, at least for the snowstorms that occasionally whip over the northern hemisphere of our neighbor planet during the icy cold winters and could be predicted several weeks in advance, say researchers from the Tohoku University in Sendai, Japan, and the Max Planck...
The application period to become a Mars settler in 2023 was officially started on April 22, and in the following two weeks more than seventy-eight thousand people have applied to the Mars One astronaut selection program, the company said.
