DailyDirt: Rockets, Man
from the urls-we-dig-up dept
International space races don’t quite inspire the same awe or fear as they did in the 1960s. There are a bunch of countries still trying to launch rockets into orbit for various reasons, but there are also quite a few commercial and amateur organizations working on space-worthy rockets. Here are just a few examples.
- North Korea tried to celebrate the 100th anniversary of the birth of its national founder Kim Il-sung with a big rocket launch. The rocket was also a thinly-disguised test for a long-range missile, but it failed by blowing up a little over a minute after launching. [url]
- The world’s first student-made rocket to hit space hasn’t quite succeeded in reaching an altitude of 100 km, but there are a number of schools working on it. A pass or fail grade for this project seems like tough grading… [url]
- SpaceX is working on designing safer and cheaper manned spacecraft, anticipating an upcoming boom in commercial space ventures. For example, its launch abort system has integrated escape thrusters mounted to the side of the crew capsule, and these engines aren’t jettisoned or wasted if the mission goes as planned. [url]

By the way, StumbleUpon can also recommend some good Techdirt articles, too.

And then there's Planetary Resources
Rumor on the street is that Diamandis, Simonyi, Schmidt and co. want to mine asteroids.

Re: And then there's Planetary Resources
That’s interesting.
But just imagine how much money they’ll need. They need to reserch on the ff key points:
1. Detect which asteroid/planet/moon has the target resources.
2. How to mine the asteroids/planet/moon.
3. How to get all the mined stuff back here.
KickStarter can’t fund this.
Re: Re: And then there's Planetary Resources
In the reading I’ve done in the last few minutes, it looks like your step 3 may not be part of the calculus at all. The mined material may be used “in situ” to help on our way to exploring/colonizing/monetizing the solar system. I will say though that Diamandis has mentioned funding such a project by speculating in the markets that such mining might impact (in a TED talk), so maybe he does intend to get the stuff back here (if that’s even what this is all about).
I agree that steps 1 and 2 are problematic, but it at least looks like we have some sense of what the rough makeup of many of the asteroids are, and what it will take to reach them, even if not economically feasible under any existing models.
Re: Re: And then there's Planetary Resources
Did you saw Cowboys & Aliens? If you did, you saw the aliens floating the gold out of the mines.

Magnetism is such a beautiful thing 🙂

You forgot point 4;
4. Prevent the extinction of the human race from alien bacteria.
I’ve seen enough movies to know that bringing aliens rocks back to Earth never ends well! 😉
Re: And then there's Planetary Resources
Mining the moon for helium isotopes might be a bit more practical — unless there are some nearby asteroids made up of really valuable materials?
Re: Re: And then there's Planetary Resources
While we’ll find out more next Tuesday about the nature of the company, I did a little follow up reading on asteroid mining. This section of the Asteroid Mining wikipedia article (along with a few other sections/pages), seems to raise the possibility that in “the near future” asteroid mining might be feasible, and specifically, NEO’s might be a better option than the moon due to the lower gravitational propellent costs:

However, this is just quick and dirty research, and the source cited by wikipedia is not one I’m familiar with, and also seems to have “this is possible!” leanings.
Re: Re: And then there's Planetary Resources
Most of the energy cost in a rocket mission is simply leaving the Earth. Once you?re out there, I don?t think there?s much energy difference between going to the Moon versus going to an asteroid. Might be slightly more energy needed to go to the Moon, simply because of its greater gravitational field.
I like the contrast between the first and second articles. Brightest minds in North Korea build rocket, explodes a minute into flight. Undergraduates in America building rocket, expected to reach space.
?thinly-disguised test for a long-range missile?
I?m no fan of the North Koreans, but propaganda is propaganda, even when it?s coming from the US. By definition, any rocket capable of reaching orbit is capable of reaching far-away points on the Earth?s surface.
Remember the US?s early rocket launches? The Redstone and Atlas rockets were explicitly designed to launch ICBMs, no ?thinly-disguised? about it! Yet both went on to serve peaceful purposes as well, launching Mercury and Gemini manned missions into space.
You have this mindset that your country is always implicitly the ?good guys?, that a military capability is good when you possess it, but bad when someone else has it. The world has never revolved around the US. Deal with it.
Re: ?thinly-disguised test for a long-range missile?
I think the issue here is who owns the trademark on “thinly-disguised”. Certainly there is a vast quantity of prior art and many who proclaim they were the “first to bullshit”. Needless to say, this particular Government Model Patent will be in the courts for some time.
