oh yea, if you got this far in the article, i would like to point out, we have a close encounter expected on february 15 with an asteroid 50 meters in length approach UNDER our geosynchronous sattelites, only 20,000 miles away.
pretty awesome. it’s not an earth killer, and i wouldn’t want it to cause any danger to actual human beings, but perhaps if it actually hits our planet, it will be a siren call that we must start going to the stroids as soon as possible with or without nasa.

A lot of uninformed opinions, a lot of people who have never heard of Tsiolkovsky’s rocket equation. Please educate yourself: http://hopsblog-hop.blogspot.com/2012/08/mf-is-mofo-tyranny-of-rocket-equation_21.html
The Falcon second stage must have a Mf of around 95%, about as tenuous as a Coke can. Designing such a structure that can survive 8 km/s re-entry is certainly not a given. I’ll believe Musk’s reusable space ships when I see them.
Both you and Simone Foxman seem fixated on gold and Platinum. Planetary Resources rightly says water is the most valuable space resource. This is because Chris Lewicki et al know a little about aerospace engineering. They’ve heard of Tsiolkovsky’s rocket equation. Unlike you, they have a clue.

“pretty awesome. it’s not an earth killer”
50 meter ‘roid could do some serious damage if it impacted the right place.

David hop, your link is geeat thank you. It confirms my statement that asteroid mining is selling the vision of delivering construction marerials to space projects rather than to earths surface. Why is it that dsi and planetary resources arent more explicit about this fact?

It looks like they aren’t allowing the public to invest. How can we invest in these companies?
