Mine the Asteroids!

posted in: exploration, science fiction, space, technology | 0

The gold rush has officially begun: the mining of the asteroids. Science fiction writers have been predicting it for decades.* Now some seriously hard-hitting billionaires and technical people are joining forces to make it happen, through a privately funded initiative called Planetary Resources, Inc. Investors include filmmaker and explorer James Cameron (yes, he who just dove the Mariana Trench), the founders of the X-Prize Foundation, Google executives Larry Page & Eric Schmidt, Ross Perot, Jr., and others. Technical people include—well, for example, the chief engineer is Chris Lewicki, who was Flight Director for NASA’s Spirit and Opportunity Mars rover missions.

They’re seriously planning to robotically explore and mine near-Earth asteroids, seeking precious metals, such as platinum-family metals, and water (very precious in space, very expensive to lift into orbit). From the Planetary Resources website:

“Initial space resource development will focus on water-rich asteroids. Water is the essence of life and exists in plentiful supply on asteroids. Access to water and other life-supporting volatiles in space provides hydration, breathable air, radiation shielding and even manufacturing capabilities. Water’s elements, hydrogen and oxygen, can also be used to formulate rocket fuel.”

Here’s a summary of a recent report suggesting that the technology to do this is available or nearly so. 

I think this is one of the most exciting developments in space exploration since the Apollo lunar landings. For more details, visit the Planetary Resources website. For a highly readable but expert analysis, read Phil Plait’s Bad Astronomy blog post: Breaking: Private company does indeed plan to mine asteroids… and I think they can do it.

I’m not an investment speculator, but if they were selling shares, I’d be in for a share today.

*My own short story, Dog Star, is based on the premise that we’ll be actively mining near-Earth asteroids; also, on the smarts of border collies.

On the Banks of the River Jordan

posted in: personal news | 0

Well, that’s poetic license, because I’m not sure if she’ll actually see the Jordan River—but my older daughter Lexi took off this afternoon for ten days in Jordan, traveling with some other folk from our church. They’ll be staying with families there, and hoping to meet and pray with some Muslim groups, and generally open some lines of conversation. I don’t know as many details as I would like, because, well, she’s twenty-two. She doesn’t exactly withhold information; she just doesn’t stop moving long enough to fill us in on everything. (I suspect other parents will know what I mean.) She’s traveling with one of the pastors of our church, a woman who has been to the Middle East several times, so that gives us some reassurance.

She was excited and nervous when she left. Allysen and I are awed, proud, and—yeah—a little nervous.

It runs in her blood. When she was fourteen, she traveled to Armenia with a local exchange group. Since then, she’s been to Mexico and Nicaragua. She gets it from her mom.

Edit: Got a text msg: “Safely in Amman.” Probably the last we’ll hear for a little while.

NASA Cuts: What Is Obama Thinking?

posted in: astronomy, public affairs, science, space | 0

Congress is right now considering future budgets for the funding of our space program, and it’s got me extremely worried. The Obama administration has proposed deep cuts, especially for planetary sciences. This is crazy, stupid, and short-sighted, and I call upon Congress to turn this thing around—please! Let’s continue funding our world-class space program, especially for space and planetary sciences, which since the Apollo days have been the capstone of American scientific exploration. The U.S. has already pulled out of one important international planetary mission, based just on the proposed budget. It would be a travesty to cancel other cutting-edge space missions.

It’s practically a given most of the American public thinks we spend a lot more on the space program than we actually do. In fact, NASA’s budget has always been a drop in the bucket compared to the Defense Department’s. Even at the height of the relatively extravagant days of the Apollo Moon landing program, the space program only accounted for a few percent of the federal budget. Since then it’s been sharply cut back. And now they want to cut it back even further. This despite the fact that every dollar spent on space helps to stimulate the economy, maintain our leadership in science and technology, inspire young scientists and engineers—and that’s in addition to advancing our knowledge of the universe, and laying the groundwork for a future spacefaring civilization.

The Obama budget would put the brakes on all of this. And when you put the brakes on a programs like this, you don’t just slow things down, you cause enormous disruption to long-range endeavors and put highly trained people out of work, people whom you might not be able to get back a few years down the road. I’m an Obama supporter, but this may be his administration’s single most misguided action.

To voice your support of space exploration, contact your Congress critter. One way you can do that is by signing on with the message from the Planetary Society, which you can dispatch to your representatives here.

The Quantum Theory of Mitt Romney

posted in: public affairs, quirky | 0

I’m not a regular New York Times reader, but this came my way and is too good not to share. In case you’re not sure if it’s accurate, let me say this: Mitt Romney was my governor. I know Mitt Romney. And if this doesn’t fit you, you’re not Mitt Romney. It’s by David Javerbaum, former head writer and executive producer of The Daily Show with Jon Stewart.

http://www.nytimes.com/2012/04/01/opinion/sunday/a-quantum-theory-of-mitt-romney.html

I hope this isn’t behind a paywall. Just in case, here’s an excerpt:

Complementarity. In much the same way that light is both a particle and a wave, Mitt Romney is both a moderate and a conservative, depending on the situation… It is not that he is one or the other; it is not that he is one and then the other. He is both at the same time….

Uncertainty. Frustrating as it may be, the rules of quantum campaigning dictate that no human being can ever simultaneously know both what Mitt Romney’s current position is and where that position will be at some future date. This is known as the “principle uncertainty principle.”

Entanglement. It doesn’t matter whether it’s a proton, neutron or Mormon: the act of observing cannot be separated from the outcome of the observation. By asking Mitt Romney how he feels about an issue, you unavoidably affect how he feels about it. More precisely, Mitt Romney will feel every possible way about an issue until the moment he is asked about it, at which point the many feelings decohere into the single answer most likely to please the asker….

Duality. Many conservatives believe the existence of Mitt Romney allows for the possibility of the spontaneous creation of an “anti-Romney”… that leaps into existence and annihilates Mitt Romney. (However, the science behind this is somewhat suspect, as it is financed by Rick Santorum, for whom science itself is suspect.)

Read the whole thing, if you can. It’s funny, and more than a little true.

Edit: On reflection, I think maybe I was being a little mean here. To Mitt Romney the political persona, well—yeah, all that’s true. But to Mitt Romney the man…sorry, guy. I don’t really know you. For all I know, you’re a great guy. I hope you had a nice Easter weekend.

Cameron Dives the Mariana Trench!

posted in: exploration, science, technology | 0

Filmmaker James Cameron (Avatar, The Abyss) has become the third human in history to travel seven miles down into the deepest part of the ocean—the Challenger Deep, in the Pacific Ocean’s Mariana Trench. He’s the first to do it alone, as leader of the Deepsea Challenge mission.


I was eleven when the Trieste made the first, two-man, dive in 1960. I’ve often wondered why nobody ever went back (just as I’ve wondered why we haven’t returned to the Moon). Well, now this team has done it, and it’s the first of a planned series of dives. Whereas the Trieste got just twenty minutes of bottom time and never returned, Cameron and the submersible Deepsea Challenger spent a couple of hours there, gathering samples and shooting 3D video. Here’s the first of many video clips about the National Geographic sponsored mission:

When I blogged, just days ago, about two separate planned expeditions, I had no idea that Cameron’s dive was imminent. And I almost missed it when it happened. The story was buried in the Boston Globe, and it’s too early for it to be in any of my science mags. In my previous forays to the Deepsea Challenge site, I’d failed to notice the prominent box where you can sign up for email updates. I’ve fixed that. But I can’t help wondering: Why aren’t stories like this front-page news? If I were running the world, they would be! Because, by God, this is exciting stuff. What a time to be alive!
