What do you get when you have 6.022×10^23 moles?

More juicy awesomeness from Randall "XKCD" Munroe's "What If?" series! This week, Randy looks at what you'd get if you marshalled a mole (6.022×10^23) of moles (small burrowing rodents). First cut: you don't want to do it on Earth, as they'd have half the mass of the moon ("This smothering ocean of high-pressure meat would wipe out most life on the planet, which could—to reddit’s horror—threaten the integrity of the DNS system.") So, you stick 'em in space, where they'd form a meaty, cooling, rotting planetoid:

The mole planet is now a giant sphere of meat. It has a lot of latent energy (there are enough calories in the mole planet to support the Earth’s current population for 30 billion years). Normally, when organic matter decomposes, it releases much of that energy as heat. But throughout the majority of the planet’s interior, the pressure is over a hundred megapascals, which is enough to kill all bacteria and sterilize the mole remains—leaving no microorganisms to break down the mole tissues.

Closer to the surface, where the pressure is lower, there’s another obstacle to decomposition—the interior of a mole planet is low in oxygen. Without oxygen, the usual decomposition doesn’t happen, and the only bacteria that can break down the moles are those which don’t require oxygen. While inefficient, this anaerobic decomposition can unlock quite a bit of heat. If continued unchecked, it would heat the planet to a boil.

But the decomposition is self-limiting. Few bacteria can survive at temperatures above about 60 °C, so as the temperature goes up, the bacteria die off, and the decomposition slows. Throughout the planet, the mole bodies gradually break down into kerogen, a mush of organic matter which would—if the planet were hotter—eventually form oil.

Famous "star cradle" might have been destroyed long before we ever discovered it

This is one of the most-famous astronomy photos in the world. Called "The Pillars of Creation" it was taken by the Hubble telescope in 1995 and shows massive columns of hydrogen gas and dust in the Eagle Nebula—7,000 light years from Earth. Part of why these are a big deal is that columns of dust and gas like this are places where stars form.

But here's a cool and/or disappointing detail I hadn't known about until today. Back in 2007, researchers took more images of this region of space using the Spitzer Space Telescope. These shots suggest that the Pillars of Creation might actually be long gone—destroyed thousands of years ago by a nearby supernova.

A striking image from Spitzer shows the intact dust towers next to a giant cloud of hot dust thought to have been scorched by the blast of a star that exploded, or went supernova. Astronomers speculate that the supernova's shock wave could have already reached the dusty towers, causing them to topple about 6,000 years ago.

However, because light from this region takes 7,000 years to reach Earth, we won't be able to capture photos of the destruction for another millenium or so.

Space is crazy, y'all.

Miles O'Brien: Ride, Sally Ride

At the PBS Newshour website, a post by Miles O'Brien about one of his encounters with the late Dr. Sally Ride, the first American woman in space. He writes about the night of January 28, 2003, when Dr. Ride knocked on the door of his house in Atlanta. She was one of the guests of honor at his home that night to celebrate the opening of a new Challenger Learning Center. And at the time, Miles (then a reporter with CNN) had just closed a deal with NASA to become the first journalist in space, on a forthcoming shuttle mission. Snip:

I normally do not ask people for autographs or inscriptions, but on this night I made an exception. I handed her my copy of the book, and she wrote: "Hope you're the first journalist in space!"

Nice words from someone who knows what it means to be first.

While she was signing, and we were celebrating, the STS-107 crew was orbiting a few hundred miles over our head-- unaware of the fatal breach in the reinforced carbon heat shield on the leading edge of Columbia's wing.

In four days, everything would change for the people in my house that night. Columbia, of course, did not make it home. Sally Ride would soon be serving on her second commission investigating the loss of a space shuttle and its crew.

Update: Here's a video segment from tonight's show, with Miles talking with Judy Woodruff about Dr. Ride's legacy. Alternate [YouTube Link].

Sally Ride's sister, on the quiet acknowledgement of her orientation: "I hope it makes it easier for kids growing up gay."

Astronaut, physicist, and American science hero Sally Ride died yesterday of pancreatic cancer, at 61. Dr. Ride was the first American female in space, and left a vast legacy of scientific accomplishments. When her astronaut days ended, she worked to promote space and science literacy to young people around the world through Sally Ride Science.

As friends and professional associates knew, and as was quietly noted in the obituary released on her website, Ms. Ride had been in a committed relationship with a woman for some 27 years. She met her partner Tam O'Shaughnessy nearly 50 years ago. Neither her cancer diagnosis nor her orientation were publicly shared, prior to her death.

Sally Ride's sister, Bear Ride, addressed this very personal aspect of Sally's very private life in comments to Buzzfeed today. "We consider Tam a member of the family," she told Chris Geidner.

"The pancreatic cancer community is going to be absolutely thrilled that there's now this advocate that they didn't know about. And, I hope the GLBT community feels the same," Bear, who identifies as gay, told Buzzfeed. "I hope it makes it easier for kids growing up gay that they know that another one of their heroes was like them."

Asked about those who would have opposed legal recognition of her sister's relationship, Bear Ride bluntly replied, "Who cares about them, really? There are those who are stubbornly ignorant, and if they want to continue in that, God bless them, but probably best not to talk to my family."

The rest of the interview is well worth a read. More about Dr. Ride in our post from the day she died.

Sally Ride, first American woman in space, has died

Dr. Sally Ride, an American physicist and former NASA astronaut, has died of pancreatic cancer. She joined NASA in 1978, and in 1983 became the first American woman to travel into space. From a statement on her website:

Sally Ride died peacefully on July 23rd, 2012 after a courageous 17-month battle with pancreatic cancer. Sally lived her life to the fullest, with boundless energy, curiosity, intelligence, passion, joy, and love. Her integrity was absolute; her spirit was immeasurable; her approach to life was fearless.

Sally was a physicist, the first American woman to fly in space, a science writer, and the president and CEO of Sally Ride Science. She had the rare ability to understand the essence of things and to inspire those around her to join her pursuits.

Character from Valve's Portal 2 game is "going to actual space"

"Wheatley," an orb-shaped robot pal in Valve Software's popular 2011 game Portal 2, is on his way to space. The unauthorized stowaway is on a Japanese spacecraft now in Earth orbit, heading to the the International Space Station (ISS).

Robert Pearlman reports:

[Wheatley] is flying aboard the Japan Aerospace Exploration Agency's (JAXA's) H-II Transfer Vehicle (HTV) that launched on Friday (July 20) to resupply the space station. The character, in miniature two-dimensional (2-D) form, is soaring through real space thanks to an unnamed NASA worker.

Valve announced on its website's blog that "thanks to an anonymous tech at NASA, Wheatley is actually going to actual space."

The one-eyed sphere, or "personality core" as referred to in the video game, is given its voice by English actor and comedian Stephen Merchant. On board the HTV, which is nicknamed "Kounotori or "white stork", the robot's voice is offered in the form of a phrase engraved under Wheatley's likeness — "In spaaaaaaace!" (Portal 2 players may associate that quote with another of the game's personality cores, the so-called "Space Core," though Valve attributes it to Wheatley on their blog.)

Photo: this image posted on Valve's website shows "what appears to be a circuit board with Wheatley's likeness laser-inscribed in one corner," according to Pearlman. We don't know the scale of the component, or the instrument it's part of.

How the Eagle Landed: Grumman Construction Log, and a message to space (Apollo 11)

On the anniversary of Apollo 11, Steve Jurvetson posted an amazing, never-before-seen series of space artifacts. He writes:

On July 20, 1969, Eagle landed on the moon. These are the handwritten notes from the Grumman engineers as they pushed to complete Lunar Module LM-5 in 1968. On the last page, they learn than this particular Lunar Module would be the one to bring the first humans to the moon.

The Grumman Engineering Log served not only as an engineering notebook but also as an intercom between the day and night shift – separate teams that needed to push the ball forward from where the other left off. So we are offered a rare peek into the concerns, uncertainties and conversations that might have otherwise been quietly undocumented.

"We are on the fucking moon" (video)

[Video Link] Yesterday was the anniversary of Apollo 11's landing on the moon in 1969, the first time humans ever set foot on another world. Today, we discover this long-lost footage and audio from that historic moment. (thanks, inkfumes!)

Spacecraft 3D: Nifty robotic space travel augmented-reality app from NASA JPL

I recently had a chance to visit NASA's Jet Propulsion Laboratory with Miles O'Brien. At the NASA center in Pasadena, engineers are readying for the long-anticipated landing of the Mars Curiosity rover on Aug. 5. During our visit, we met with the team behind a cool new iOS app from JPL: NASA's Spacecraft 3D, an augmented reality application that allows users to "learn about and interact with a variety of spacecraft that are used to explore our solar system, study Earth, and observe the universe."

Using a printed AR Target and the camera on your mobile device, you can get up close with these robotic explorers, see how they move, and learn about the the engineering feats used to expand our knowledge and understanding of space. Spacecraft 3D will be updated over time to include more of the amazing spacecraft that act as our robotic eyes on the earth, the solar system and beyond!

The app is really a ton of fun. You can download it here for free, iPad and iPhone and iPod Touch. Here's the JPL press release announcing its release.

Shuttle Enterprise goes on display today at NYC's Intrepid Sea, Air, and Space Museum

New York City's Intrepid Sea, Air & Space Museum opens the doors on a new Space Shuttle Pavilion today. Its central tenant? The Space Shuttle Enterprise (NASA Orbiter Vehicle Designation: OV-101). Starting today, you can visit the Pavillion and walk underneath and around the first space shuttle NASA built. The orbiter never actually went to space, but did perform important test flights in 1977, which paved the way for the shuttles that followed.

Young space expert Sawyer Rosenstein, who hosts and edits the Talking Space podcast, and is a consultant-to the Intrepid Sea, Air, and Space Museum, visited before the exhibit opened to the public. He shot these fantastic sneak-peek photos, and shares them with Boing Boing here (the captions are his observations).

Sawyer says:

Having seen the orbiter from concept, to piggyback, to craning, to finished, the Intrepid has come a long way, and they did a phenomenal job with it. Team Intrepid is absolutely amazing and they put together an amazing exhibit for an amazing vehicle, and have set up a way to continue teaching about the space program. As I said to one person at the event, "If you don't want to become an astronaut after seeing this, then you might need to get checked out."

Also: If you missed it before, be sure to read Sawyer's excellent guest feature, "Don’t tell me the sky is the limit when there are footprints on the moon."

Religion, space, and the power of cultural connections

That's a picture of an Orthodox Christian priest, blessing the launch of a Soyuz spacecraft.

It seems like a weird and outdated pairing: Religion and space exploration. But they're actually a lot more intertwined than you might think, writes Rebecca Rosen at the Atlantic. A lot of astronauts are religious. A lot of astronauts that aren't really religious seem to have an urge to carry the cultural traditions of religion into space. And religion returns the favor. For instance, The Book of Common Prayer now includes an astronaut option in its prayer for travelers: "For those who travel on land, on water, or in the air [or through outer space], let us pray to the Lord."

I'm sorry. I'm an atheist and that just kind of gave me the shivvers. Basically, being out in space, so far from your fellow humans and in such an alien environment, makes for a really good example of the way religion (and ritual) can serve as a tie binding us to the rest of humanity. For some people, it's a connection to a bigger sense of history. And when they look the future (and/or the vast emptiness of space) full in the face, they need that connection to humanity. It doesn't work for everybody. But the relationship between religion and space travel is a good place to start when you want to have a conversation about the fact that there really don't have to be conflicts between religion and science. (Really, people. For serious.)

Here's the scene: It's Christmas Eve, 1968. The spaceship with three men on board had hurtled toward the moon for three days, and they have now finally entered the moon's orbit, a move requiring a maneuver so dicey that just a tiny mistake could have sent the men off into an unwieldy elliptical orbit or crashing to the moon's surface. But all went smoothly, and they are orbiting the moon. On their fourth pass (of 10), astronaut William Anders snaps the famous Earthrise shot that will appear in Life magazine. On their ninth orbit, they begin a broadcast down to Earth. Astronaut Frank Borman introduces the men of the mission, and, then, this:

"And the earth was without form, and void; and darkness was upon the face of the deep. And the spirit of God moved upon the face of the waters and God said, 'Let there be light," Borman read.

Google unveils Street View imagery from Antarctica, including South Pole Telescope, Shackleton sites

Photo: Cape Royds Adélie Penguin Rookery. (Google Street View)

Today, Google is launching access to a new collection of hi-res imagery from the Antarctic. In this post are some examples of those stunning vistas, shared with Boing Boing courtesy of Google. Alex Starns, Technical Program Manager for the Street View team, writes:

Back in September 2010, we launched the first Street View imagery of the Antarctic, enabling people from more habitable lands to see penguins in Antarctica for the first time. Today we’re bringing you additional panoramic imagery of historic Antarctic locations that you can view from the comfort of your homes. We’ll be posting this special collection to our World Wonders site, where you can learn more about the history of South Pole exploration.

With the help of the Polar Geospatial Center at the University of Minnesota and the New Zealand Antarctic Heritage Trust, we’ve added 360-imagery of many important spots, inside and out, such as the South Pole Telescope, Shackleton's hut, Scott’s hut, Cape Royds Adélie Penguin Rookery and the Ceremonial South Pole.

More about the project here. And more images below!

Are you optimistic or pessimistic about humankind's ability to prevent a killer asteroid from killing us all?

NewImage
In his book, The Beginning of Infinity, Oxford physicist David Deutsch writes:

If a one kilometer asteroid had approached the Earth on a collision course at any time in human history before the early twenty-first century, it would have killed at least a substantial proportion of all humans. In that respect, as in many others, we live in an era of unprecedented safety: the twenty-first century is the first ever moment when we have known how to defend ourselves from such impacts, which occur once every 250,000 years or so.

Documentary filmmaker Errol Morris wants to know what you think of Deutsch’s claim, and has set out a brief survey on his blog at the New York Times. Morris told me, "It may seem like another innocuous Internet quiz, but take my word for it—it isn't one." He also said, "There is a hidden question, which I’m not at liberty to reveal, that I think will interest you." and on his blog, he writes "When the results are announced, there will be a surprise."

I'm intrigued! I love surprises, even when they involve killer asteroids.

Are You an Optimist or a Pessimist?
