Not in Houston Anymore.

“The artist Scott Listfield has a fixation for astronauts, painting them over 130 times since the early 90s. You’ll typically find them gazing in blank-eyed wonder at pop icons like Optimus Prime, Mario’s coins twinkling behind a cloud, and the Queen in Aliens…Perhaps there’s a statement in this, something about the decline of the Space Age and the cult of culture. Maybe he just likes painting astronauts.”

I feel like I may have blogged this at some point in the past, but couldn’t readily find it. At any rate, and Killscreen points the way to Scott Listfield’s AstronautDinosaur, where NASA’s finest find themselves on all manner of adventures.

All These Worlds Except…

“Robinson said the high radiation environment around Jupiter and distance from Earth would be a challenge. When NASA sent Galileo to Jupiter in 1989, it took the spacecraft six years to get to the fifth planet from the sun. Rensselaer Polytechnic Institute astronomer Laurie Leshin said it could be ‘a daring mission to an extremely compelling object in our solar system.’…Harvard astronomer Avi Loeb said going to Europa would be more exciting than exploring dry Mars: ‘There might be fish under the ice.'”

NASA sets aside some money for a robotic mission to Europa. “No details have been decided yet, but NASA chief financial officer Elizabeth Robinson said Tuesday that it would be launched in the mid-2020s.”

A World of Worlds.

“‘This is the largest windfall of planets — not exoplanet candidates, mind you, but actually validated exoplanets — that’s ever been announced at one time,’ Douglas Hudgins, exoplanet exploration program scientist at NASA’s Astrophysics Division in Washington, told reporters today.”

NASA announces 715 new planets found by the Kepler telescope, and that’s only from the first two years of data. “About 94 percent of the new alien worlds are smaller than Neptune, researchers said, further bolstering earlier Kepler observations that suggested the Milky Way galaxy abounds with rocky planets like Earth…four of the worlds are less than 2.5 times the size of Earth and reside in the ‘habitable zone,’ that just-right range of distances that could allow liquid water to exist on their surfaces.”

Pouring Down All Over Mars.

“So, how does water flow in the frigid Martian temperatures that are present, even in the summer months? Researchers think that there may be a naturally-occurring anti-freeze in the water, caused by the high-iron content…the water and ferric iron flowed together as part of a brine.”

Via io9, Scientists at NASA’s JPL find the strongest evidence of currently extant water on Mars yet. “We still don’t have a smoking gun for existence of water…Although we’re not sure how this process would take place without water.”

Only One Absolute…Everything Freezes.

“‘We’re going to study matter at temperatures far colder than are found naturally,’ says Rob Thompson of JPL…’We aim to push effective temperatures down to 100 pico-Kelvin.’ 100 pico-Kelvin is just one ten billionth of a degree above absolute zero, where all the thermal activity of atoms theoretically stops. At such low temperatures, ordinary concepts of solid, liquid and gas are no longer relevant. Atoms interacting just above the threshold of zero energy create new forms of matter that are essentially…quantum.”

In the nearest reaches of space (a.k.a. the ISS), NASA scientists plan to create the coldest spot in the universe, in order to toy with the fabric of reality. “No one knows where this fundamental research will lead. Even the ‘practical’ applications listed by Thompson — quantum sensors, matter wave interferometers, and atomic lasers, just to name a few — sound like science fiction. ‘We’re entering the unknown,’ he says.’

Martian Vineyard.

“The layer of rock, called the Sheepbed mudstone, has several qualities that indicate it formed in an environment that was hospitable to life. First, the thickness of the rock indicates that the lake existed in that area for a long period of time. Second, chemical analysis showed that the lake had all the right ingredients for life. According to Grotzinger, the lake would have been roughly half the size of one of the Finger Lakes in upstate New York.”

Where do bad folks go when they die? They don’t go to heaven where the angels fly. Mars? Hrm…well, maybe. Curiosity finds the remnants of what appears to be an ancient Martian lake in Yellowknife Bay, part of Gale Crater. Unfortunately, “[e]ven if there were fossils in the mudstone, Curiosity doesn’t have the right kind of equipment to see them. That job will be left to the Mars rover set to launch in 2020.”

Cthulhu Fhtagn!

“The National Reconnaissance Office, tasked with watching the earth through largely classified satellite programs, recently launched a new rocket into space. That rocket’s classified contents were marked with an incredibly subtle image: an octopus spreading its tentacles across the globe, over the words “nothing is beyond our reach.” Charming!”

Er, yeah, not sure what they were thinking there. In any event, in honor of this dubious messaging, Popular Science offers eight historical examples of octopi taking over the world. Above is Standard Oil, smothering both ends of Congress with its undulating, oleaginous reach.

Farewell, Europa.

“The ASRG program was created to help extend the life of the remaining Pu-238 supply. It uses a Stirling engine to generate electricity at four times the efficiency of a regular RTG. This means more missions to these harsh places using less Plutonium. While NASA has started to generate Pu-238 again, it won’t be ready to use until 2019, and even then the Department of Energy will only produce about 1kg – 1.5kg per year. The New Horizons mission to Pluto used about 11kg, which would take anywhere from 7 – 11 years to generate under the current plan.”

Because of sequestration and other budget cuts, NASA is forced to cancel its advanced spacecraft power program, threatening future missions past the asteroid belt. “ASRGs had been under development by NASA for over a decade, and had been planned for use by 2016 in the next low-cost planetary exploration missions…Because of the limited cost cap imposed on these missions, they’re now essentially limited to the inner solar system. Missions with bigger budgets that could afford regular RTGs will be bottlenecked by the production rate of Plutonium to maybe once or twice per decade. Goodbye, outer planets.”

Explorers on the Moon.

“The next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.” A belated happy 44th anniversary to the Apollo 11 crew, the first without Neil Armstrong. Speaking of which, it’s now been over 40 years since man walked on the moon — ’bout time to go back, dontchathink? (Spiffy Tintin image via LinkMachineGo.)
