NASA’s Going a Bit Moon Crazy

Roughly 40 years after they actually landed on the thing but who am I to judge?

Fuck that, I judge all the time. That’s not important now.

First off, the Moon-scope:

In the Moon’s weak gravity, it might be possible to build a telescope with a mirror as large as 50 meters across, half the length of a football field—big enough to analyze the chemistry on planets around other stars for signs of life.

That’s the dream of Peter C. Chen, astrophysicist at NASA Goddard Space Flight Center. And he wants to build it using lunar dust—because that might just be the most economical approach.

“If we lift all materials from Earth, we’re limited by what a rocket can carry to the Moon,” Chen explains. “But on the Moon, you’re absolutely surrounded by lunar dust”—a prized natural resource in the eyes of Chen, an expert in composite materials.

next up, Water on the Moon:

A new analysis of Apollo 15 moon rocks has for the first time uncovered water locked up inside.

It’s just a miniscule amount of the wet stuff — not enough to sustain even a lunar cactus or to power any hydrogen jetpacks — but the discovery does bolster hopes that there has always been water in moon rocks and perhaps some locked away as ice in the dark crannies of polar craters.

The discovery also overturns 40 years of studies which had failed to find the water and which led to the conclusion, drawn by most planetary scientists, that moon rocks must be all dry.

[…]

One of the ramifications of the newfound water is that it calls into question some of the details about the way the moon formed. The most popular current theory is that a Mars-sized body sideswiped Earth about 4.5 billion years ago, creating a ring of debris that eventually coalesced into the moon.

Ahoy There! NASA Set to Test Solar Sails

The agency plans to fly a tiny probe known as NanoSail-D, which is scheduled for launch later this month aboard an experimental Falcon 1 rocket, built by Internet entrepreneur Elon Musk‘s new startup, Space Exploration Technologies.

NanoSail is not the primary payload and it will be booted off the launcher rather early in the flight. Because the spacecraft will be left in an elliptical rather than circular orbit around Earth, it will be dragged back into the atmosphere as early as five days after launch.

[…]

If the Voyager probes had solar sails, for example, they would have reached the outer edges of the solar system in about a decade, rather than the 30 years it has taken for them to reach their present locations, Montgomery said.

“If you’re going far away, the sail will eventually get you there sooner,” he said.

Solar sails are most useful where sunlight is strongest — the inner solar system. With sails, satellites could change orbits, hover and steer themselves out of orbit upon completion of their missions to avoid becoming a hazard to other, still operational satellites.

Floating Cities: Possible End Future, Nicer than Waterworld

Although I marked this as Just Freaking neat, I don’t wish it to happen.

Mostly.

There are very few urban design solutions that address housing the inevitable tide of displaced people that could arise as oceans swell under global warming. Certainly none are as spectacular as this one. The Lilypad, by Vincent Callebaut, is a concept for a completely self-sufficient floating city intended to provide shelter for future climate change refugees. The intent of the concept itself is laudable, but it is Callebaut’s phenomenal design that has captured our imagination.

Ancient Red Ink Possibly Killed Monks

Medieval bones from six different Danish cemeteries reveal that monks who wrote Biblical texts and other religious materials may have been exposed to toxic mercury, which was used to formulate just one of their ink colors: red.

The study, which will be published in the August issue of the Journal of Archaeological Science, also describes a previously undocumented disease, called FOS, which was like leprosy and caused skull lesions. Additionally, the researchers found that mercury-containing medicine had been administered to 79 percent of the interred individuals with leprosy and 35 percent with syphilis.

[…]

Other religious groups may have experienced mercury poisoning due to scripting holy texts. In a separate study, scientists from the Soreq Nuclear Research Center in Israel and the Israel Museum found cinnabar on four fragments of the Dead Sea Scrolls, which include passages from the Hebrew Bible.

READ: Make the Red Planet, Our Planet

Warren Ellis has been talking an awful lot about Mars this past week. This is a good thing cause Mars has been on my mind for some time now. (Note the filing category of this post.) But yes. “Bending” Mars. Making the Red Planet our planet. Our sister petri dish for continuance of the species. This must happen. Find good things out their Mars Phoenix. Find them and give people an idea on what our next off-planet move will be.

So my characters — and the dark side of my conscience — say what are we waiting for? Let us now bend Mars to our will (and I’m aware of the overtones of both ”run a railroad” and ”will”) and fix the place up for human habitation. Let’s cover the bastard in GM lichen and bugs, thicken up the atmosphere, drop a few nukes on Tharsis, do everything we can think of, fast and dirty, because the universe is hiding the stopwatch from us and we don’t know how much time we’ve got left. Let’s get a bit of air pressure happening, see if we can force out some of that water, do what it takes to at least get some overground stations into a safety zone.

Because it’s not doing us any good as a national park. And we are barely clinging to the surface of our world. And not through any fault of our own. Successful human life was a fluke on this planet even before we started poisoning ourselves. Playing the “we need to learn how to look after our planet before we go to another” lament is utterly beside the point. Think about your favourite art, your favourite memories, the best things people ever did. Does that have to go away because some people want Mars to always look like that quarry in Wales where they always shot DOCTOR WHO episodes in the 1970’s?

Read the complete entry “Bending Mars” and its predecessor “Stabbing Mars.”

Former Australian of the Year Wants to Change Color the Sky

Former Australian of the Year and climate change activist Tim Flannery has come up with a novel solution to climate change, which he says could change the colour of the sky.

Professor Flannery, who has written extensively on environmental issues, spoke at a business and sustainability conference in Parliament House today and suggested a plan to pump sulphur into the atmosphere in order to repel the sun’s rays.

He says the process is called “solar dimming”.

Mr Flannery, you did not just suggest we use the plot to HIGHLANDER 2 to solve Global Warming.

Please tell me you didn’t just say that.

The Buddha Machine is Curious, Confuses

homebuddha.jpg

The Buddha Machine is a little plastic box that plays music.

Specifically, FM3 constructed nine drones, varying from two seconds to 42 seconds, which repeat endlessly in the listener’s ear until the “track” is switched to the next drone (or the two AA batteries run out).

The machine has its own built-in speaker, in case one would like to fill a room with the drones, but there is also a headphone jack for more personal meditative experiences. There’s a switch on the side that allows for traversal of the tracks, and a DC jack (though an adapter is not included) for those who would like the Buddha Machine experience be truly endless.

In a way, it’s like the cheapest pre-loaded IPod you’ll ever be able to buy.”
