I can’t believe it. I actually had the time between Boxing Day shopping and family dinner this evening to put my post up. I love it when a plan comes together 😉
Happy Boxing Day, everyone!
AB: Let me just say this: Armageddon is not a documentary.
WL: Asteroids pass Earth all the time. There’s an asteroid that will pass us on the far side of the moon, about 15,000 miles. The Hallowe’en asteroid. Mining asteroids is feasible, but we’d need rockets bigger than the Saturn 5. Space-X is developing the Falcon Heavy, which could be used for the purpose. Our planetary resource needs could be met by mining four asteroids. There is a parallel between the exploration of space and the exploration of the new world. Spice used to be as expensive as gold until the Spice Islands were discovered. It will be expensive to mine asteroids until we have sufficient access to the resources we need to make it reasonable.
Q: Can a solar mirror be used to melt asteroids?
WL: For resource processing in situ, a solar mirror could be used to smelt minerals. If we can figure out a cost-effective way to mine asteroids, we could become a true space-faring species.
EC: Terrestrial mining is a huge part of the Canadian economy. Can we transfer these skills to the mining of asteroids?
WL: The short answer is, yes. There’s a lot of enthusiasm within the industry for making the leap. Deep mining drills are taking place in Sudbury and a paper is being prepared, a feasibility study.
EC: Back to you Andrew. You said before that Armageddon was science fiction.
AB: I’m not the expert. I’m just and author who likes to write about asteroids. My research tells me that asteroid settlement is possible. James S.A. Corey (actually two co-authors) writes about the Belters, who make a living mining the asteroid belt for water to supply settlements on Mars and Jupiter’s moons. Asteroids are actually spinning rubble piles.
Q: Diverting asteroids away from Earth is supposed to be more effective than trying to blow the up. Are there any practical experiments or is this all fiction?
AB: We could use a kind of gravity tractor to divert asteroids. There’s not a lot of drama in the process, though, so people don’t write about that.
WL: If the asteroid impact is immanent, we would have to try blowing it up. If we can spot the asteroid at least ten years out, we would have the time to mount a mission to divert it.
EC: The budgets for the films Armageddon and Deep Impact were both orders of magnitude greater than the budget astronomers have for asteroid detection.
AB: There’s a probe that has been sent to the inner solar system, to Venus and closer to the sun. It’s intended to detect asteroids orbiting in the inner solar system. There’s danger from that direction, too.
Q: What complications does the spinning of the asteroid pose to landing on it?
AB: It’s problematic because there are voids in the asteroid a probe or landing vehicle could be lost.
And that was time.
Next weekend, I’m going to take a break from CanCon do write my year-end Next Chapter update, and, if I have time, I want to put together a post on how to set up Jamie Raintree’s new writing and revision tracking spreadsheet. I was asked to do this back in the spring by some writer friends who aren’t Excel-savvy, but realized that doing it when the spreadsheet is fresh off the presses would be better. Sorry for the delay, ladies!
We’ll see how it goes 🙂
In the meantime, I hope everyone is safe and cozy with their loved ones and if anyone dared Boxing Day madness, that they’re all home and none the worse for wear (if a little poorer in their bank accounts).
