There is bad news for those planning to go to Mars in the near future: a study in mice has suggested that radiation in space could cause cognitive decline in astronauts. However, we know from past research that mental, social and physical exercise can boost cognitive functions. With planned Mars missions moving ever closer, it might be be worth exploring activity as a way to counter radiation damage.

There are many hurdles to overcome to get to Mars. The obvious one, of course, is the amount of time it takes – about eight months. But for those brave enough to attempt such a journey, this may well be acceptable. What could be harder to accept, however, are the harmful galactic cosmic rays you’d be subjected to, produced by supernovae far away from Earth.… Read the rest

Philip K. PreDICKtions

Precog

In 1981, Philip K. Dick seemed to cast himself as one of the Precogs from Minority Report, when he offered a list of his own prognostications to be published in the collection Book of Predictions. Here’s what PKD saw when he stared into the crystal ball courtesy of the PKD Otaku fan zine, issue number 11, 2003…

1983
The Soviet Union will develop an operational particle-beam accelerator, making missile attack against that country impossible. At the same time the U.S.S.R. will deploy this weapon as a satellite killer. The U.S. will turn, then, to nerve gas.
1984
The U.S. will perfect a system by which hydrogen, stored in metal hydrides, will serve as a fuel
source, eliminating a need for oil.
1985
By or before this date there will be a titanic nuclear accident either in the U.S.S.R. or in the U.S.,
resulting in shutting down all nuclear power plants.

Mars has belts of glaciers consisting of frozen water

Mars distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes – between the blue lines, in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as the surface of the ground, but radar measurements show that there are glaciers composed of frozen water underneath the dust.

Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the ground, but radar measurements show that underneath the dust there are glaciers composed of frozen water. New studies have now calculated the size of the glaciers and thus the amount of water in the glaciers. It is the equivalent of all of Mars being covered by more than one meter of ice.

NASA Wants To Give The Moon A Moon

Why on earth would NASA want to give the Moon its own moon? Wired reports:

It sounds almost like a late ’90s sci-fi flick: NASA sends a spacecraft to an asteroid, plucks a boulder off its surface with a robotic claw, and brings it back in orbit around the moon. Then, brave astronaut heroes go and study the space rock up close—and bring samples back to Earth.

Except it’s not a movie: That’s the real-life idea for the Asteroid Redirect Mission, which NASA announced today. Other than simply being an awesome space version of the claw arcade game (you know you really wanted that stuffed Pikachu), the mission will let NASA test technology and practice techniques needed for going to Mars.

The mission, which will cost up to $1.25 billion, is slated to launch in December 2020. It will take about two years to reach the asteroid (the most likely candidate is a quarter-mile-wide rock called 2008 EV5).

NASA’s Curiosity rover finds fresh signs of ingredients for life on Mars

Mars’s life-friendly past just got friendlier. Using samples previously collected by the NASA rover Curiosity, scientists have discovered evidence of nitrates in Martian rock: nitrogen compounds that on Earth are a crucial source of nutrients for living things.

The findings, published in the journal Proceedings of the National Academy of Sciences, lend further support to the idea that the Red Planet, now barren and dry, could once have hosted habitable environments.

Although planetary scientists have been on the hunt for organic carbon – the type of carbon-containing molecules that could be used and produced by living things – nitrogen also plays an essential role in life as we know it, said lead author Jennifer Stern, a planetary geochemist at NASA Goddard Space Flight Center in Greenbelt, Md.

For example, nitrogen is a key component of nucleobases that make up RNA and DNA, and of amino acids, the building blocks of proteins.

Astronomers spot clouds on Mars: Is the U.S. Government terraforming the red planet?

Via Shepard Ambellas at Intellihub:

Cloud-like formations were originally spotted within the atmosphere of Mars by astronomers in 2012, leading some to believe the planet may be habitable or is being transformed in some way to make it so.

In fact images show the vapor formation to be over 621 miles across, which is larger than any other formation previously spotted within the red planet’s atmosphere to date.

A planetary scientist with the European Space Agency says this “raises more questions than answers”.

Damien Peach, an astronomer said, “I noticed this projection sticking out of the side of the planet. To begin with, I thought there was a problem with the telescope or camera. But as I checked more of the images, I realized it was a real feature – and it was quite a surprise.”

According to reports the haze lasted about 10-days before reemerging about 30-days later as it appears these new clouds are beginning to form in a more consistent manner than ever before, bringing only one thing to mind — the 1990 science fiction film Total Recall starring Arnold Schwarzenegger.

Mars One Announces The 100 Candidates To Fly To And Die On Mars

Most of you will have read about Mars One, the project to colonize Mars. The last 100 people from whom the astronauts will be drawn have just been announced:

From the initial 202,586 applicants, only 100 hopefuls have been selected to proceed to the next round of the Mars One Astronaut Selection Process. These candidates are one step closer to becoming the first humans on Mars.

“The large cut in candidates is an important step towards finding out who has the right stuff to go to Mars,” said Bas Lansdorp, Co-founder & CEO of Mars One. “These aspiring martians provide the world with a glimpse into who the modern day explorers will be.”

The Mars 100 Round Three candidates were selected from a pool of 660 candidates after participating in personal online interviews with Norbert Kraft, M.D., Chief Medical Officer. During the interviews the candidates had a chance to show their understanding of the risks involved, team spirit and their motivation to be part of this life changing expedition.

Meet the people who have volunteered to die on Mars


Walker Lamond via BoingBoing:

Thousands of people are competing to be the first humans to travel to Mars and colonize it. The only catch–they can never come back. Ever.

Mars One, an interplanetary travel nonprofit, will soon select the next round of wannabe astronauts from the nearly 700 current finalists. While making a short movie about the competition for The Guardian, we at Stateless Media had a chance to speak to a few people vying for one of the coveted seats on a Mars One Spaceship. I learned the following: they are all really smart, incredibly brave, and a little bit crazy.

Actually, they’re a lot of bit crazy. And that’s a good thing. Because it takes a certain kind of person to choose to live the rest of their lives stranded on a desert planet with no breathable air, no Netflix, no Snapchat, no Game of Thrones, no General Tso’s Chicken, and no long, romantic walks on the beach.

NASA Rover Finds Active and Ancient Organic Chemistry on Mars

via Nasa from December 16:

NASA’s Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory’s drill.

“This temporary increase in methane — sharply up and then back down — tells us there must be some relatively localized source,” said Sushil Atreya of the University of Michigan, Ann Arbor, a member of the Curiosity rover science team. “There are many possible sources, biological or non-biological, such as interaction of water and rock.”

Researchers used Curiosity’s onboard Sample Analysis at Mars (SAM) laboratory a dozen times in a 20-month period to sniff methane in the atmosphere.
