NASA Scientists Prepare For Life On Mars


NASA Scientists Prepare For Life On Mars
Four men and two women will spend eight months in a dome on a Hawaiian volcano, as part of a human behavior study designed to help NASA prepare astronauts for the journey to Mars.
     January 21, 2017 —The eight-month journey to Mars is expected to be arduous, with its cramped conditions, isolation, and monotony. By simulating Mars-like conditions on Earth, NASA hopes to learn how to mitigate the challenges.

On Thursday, the latest simulation began. Four men and two women – carefully selected from over 700 applicants – moved into a vinyl-coated pod just below the summit of Mauna Loa, the world’s largest active volcano. During their eight-month stay, which mimics the journey to and life on Mars, they will eat primarily freeze-dried foods, have limited personal space, and experience a 20-minute lag in communications (the length of time it takes a message to travel from Mars to Earth).

Alien Probes Could Be Surfing the Galaxy

      Computer simulations by a pair of researchers at the University of Edinburgh predict that a fleet of interstellar probes could explore the entire Milky Way galaxy within a fraction of the present age of Earth. This may seem like a tall order considering that our farthest interstellar spacecraft, Voyager 1, is still less than a light-day from Earth after being launched 36 years ago.

In the new simulation, however, alien probes only need to travel at 10 percent the speed of light to survey the entire galaxy within 10 million years. And, they could get a turbo-boost and save fuel by doing a slingshot off the gravitational fields of stars.

The concept of self-aware and self-replicating probes traveling across the galaxy is nothing new, however; the idea goes as far back as 1960. It was promoted by SETI pioneer Ronald Bracewell as an alternative to listening for interstellar artificial radio signals. The idea of a machine capable of cloning itself goes back at least 100 years; mathematician John von Neumann detailed the operation of such a robot in 1949. . . .
