The Project:

Space tourism is still a long ways off, but it’s not hard to imagine that someday, tourists will visit the natural geological landmarks of other worlds much like they tour the Grand Canyon, Mount Everest or Ayers Rock. Each of these great tourist destinations needs a classic retro travel poster to entice visitors. Until the day people settle off world and make their own destinations many of these may be the places that people will want to travel too. I hope that these posters can inspire people to think beyond our world to the limitless possibilities of the Universe.

This guys art is friggin amazing, plus he did a poster on the 5th Element so I automatically love him

The number of places in our solar system that could have ever supported life now stands at 2!

The first, of course, is Earth, because … well, us. According to an awesomely exciting announcement today by NASA and JPL, we can add Gale Crater to that list! 

What they found: Curiosity’s rock drill recently uncovered clay-like minerals below Gale Crater’s rusty red surface. These muddy minerals, pictured above, hint at a “Gray Mars” era, when Gale Crater and the ancient stream bed it holds could have been home to intermittent lakes. When the onboard instruments scanned the chemical makeup of the clay, it found carbon, hydrogen, oxygen, nitrogen, phosphorous and sulfur compounds, a group of elements known as “CHONPS” that have to exist in order to create life as we know it. Most importantly, the minerals were pretty neutral in pH and were found in forms that point to a possible chemical energy system (another key ingredient for life).

What remains unknown: This does NOT mean that anything ever actually lived there. But it is the first time that the ingredients for the evolution of microbial life, and the correct conditions to support it, have been directly observed beyond Earth. Mars still has water frozen at its poles, and once had quite a bit of water above and below the surface. The rover will poke around this site, called Yellowknife Bay, for a while longer before heading toward the mountainous center of Gale Crater. There, it will study the multiple layers of rock present on the hillside in order to piece together an even clearer picture of Gale Crater’s muddy, moist, maybe* microbial Martian past.

*Maybe. Just want to emphasize that part.

Achievement Unlocked!

Imagine a Living Mars

Mars was likely not always the desolate, red-rocked planet that we see today. The Curiosity rover has found what appear to be water-smoothed pebbles, shaped by ancient rivers of flowing water. Curiosity and previous missions have also seen footprints of alluvial fans and river deltas, sure signs of a previously wet world.

Software engineer Kevin Gill has taken those observations to the next level with these simulations of a “living” Mars, covered with seas and lakes and teeming with vegetation and clouds. He used a survey of Martian terrain and elevation, plugged in a sea level to form oceans, and then painted the clouds and terrain as it might look or have looked.

It’s definitely more an exercise in imagination than in reality, as there’s no indication of past forests or marshy plains on the red planet, but it’s an informed imagination, a realization of a planet’s possible rich past or terraformed future.

NASA Rover Finds Old Streambed On Martian Surface

PASADENA, Calif. — NASA’s Curiosity rover mission has found evidence a stream once ran vigorously across the area on Mars where the rover is driving. There is earlier evidence for the presence of water on Mars, but this evidence — images of rocks containing ancient streambed gravels — is the first of its kind.

Scientists are studying the images of stones cemented into a layer of conglomerate rock. The sizes and shapes of stones offer clues to the speed and distance of a long-ago stream’s flow.

“From the size of gravels it carried, we can interpret the water was moving about 3 feet per second, with a depth somewhere between ankle and hip deep,” said Curiosity science co-investigator William Dietrich of the University of California, Berkeley. “Plenty of papers have been written about channels on Mars with many different hypotheses about the flows in them. This is the first time we’re actually seeing water-transported gravel on Mars. This is a transition from speculation about the size of streambed material to direct observation of it.”
