When NASA's Curiosity Rover reaches Mars this August, it'll takes seven minutes to get from the tip of the atmosphere to the surface of the planet. Those seven minutes are a little scary for engineers who've sunk a lot of time into this project, so the descent is called the "seven minutes of terror." Here it gets highlighted by an awesome, super-dramatic video.
Researchers have discovered evidence that there's a lot more water on Mars--at least on parts of Mars--than anyone previously thought. Using new technology, scientists examined the water content in meteorites from the planet, and it points to a lot of it in the Martian mantle.
"Turn it just like this," the uniformed instructor tells the alert crew of trainee astronauts gathered around the workspace. "And then this next piece twists in the other direction." The first trainee approaches the table.
The instructor, Rupert Spies, is reassuring. "Or, if you don't want épi de blé, you could just leave the dough as a regular baguette."
We are at Cornell University, in a culinary classroom, where nine elite trainees are preparing for a simulated space mission. They are spending a week here learning how to cook on Mars. Today's lesson is on baking bread and pizza from scratch.
One of the primary obstacles to human colonization of Mars is the funding -- creating a habitable environment and sending humans across the gulf of space is a costly process, well beyond the exploration budgets of most nations. But Nobel Prize-winning physicist Gerard 't Hooft and Big Brother co-creator Paul Romer have a brilliant solution that will put colonists on Mars by 2023.
The key: Fund the whole shebang by turning the mission into reality TV.
Getting humans to Mars is a challenge in several steps, with the most difficult and dangerous likely to be the descent. Landing safely on another world is hard for a rover, let alone a spacecraft carrying people.
Since the Viking Mars probes traveled to the red planet back in 1976, NASA has sent several more probes, landers, and rovers to the Martian surface to study the planet’s geology and search for signs of microbial life. But the evidence for life may have been hidden in Viking’s data all along. A new analysis of the data collected by probes Viking 1 and Viking 2 suggest the missions found evidence of microbial life more than three decades ago.
Director Andrew Stanton and production designer Nathan Crowley talk about Mars, John Carter, and building a 100-year-old science fiction universe

John Carter is a movie that has that has taken exactly 100 years to reach theatres, and not for a lack of trying. Edgar Rice Burroughs first published A Princess of Mars--the book upon which the movie is based--in March 1912, as a serial in the pulp magazine All-Story. His ideas would soon come to influence so many major science fiction works of the 20th century that John Carter inevitably has to compete against the story's own offspring. We talked to director Andrew Stanton and production designer Nathan Crowley about the making of the film, and why science fiction is always invisibly handcuffed to society.
On August 5, NASA’s Mars Science Laboratory will reach the outer edge of the Martian atmosphere. The 8,500-pound craft will have traveled 352 million miles at speeds of up to 13,200 mph, but its real work will have only just begun. Over the next seven minutes it will plummet through 80 miles of atmosphere, withstanding temperatures of up to 3,800°F, and guide itself to a sudden halt in the massive Gale Crater.
When NASA's new Mars rover lands on the Red Planet this summer, it's safe to assume it'll be some time in the morning or early afternoon at the Jet Propulsion Laboratory in California, home of the rover science and engineering teams. So that means it'll be mid-afternoon on the East Coast, evening in Europe, and so on —- pretty easy to figure out the time zones. But what time will it be on Mars? What time zone will Curiosity live in -- and how can you even tell?
Timekeeping on Mars is a bit like telling time on Earth, because the planets are similar in lots of ways. But there are just enough differences to drive a person slightly crazy.
