"One Asteroid to Go, Please" Popular Mechanics
1. Measure It A slew of laser radar sensors measures the dimensions of the asteroid. A spacecraft then deploys its high-strength capture bag to the appropriate size. Inflatable arms and cinching cables unfurl to enclose the asteroid.
2. Bag It The spacecraft bags the rock. The finish on the bag’s exterior ensures that the asteroid doesn’t heat up and lose water.
3. Bring it Home The craft makes the long trip back to lunar orbit. The return trip could take six years; mining commences on arrival.

Asteroid Mining Mission Overview (Subtitled in Any Language)
“Since 2010, a world-class team has been quietly working to expand humanity’s resource base. Their path forward is to mine asteroids that have high concentrations of water and precious metals.
Everything we hold of value on Earth–metals, minerals, energy, water, real estate– are literally in near-infinite quantities in space. Planetary Resources’ mission is to gain access to natural resources of space by mining near-Earth-approaching asteroids. With technological advances that are coming out of exponential technologies and investors willing to bear the risk, small teams are now able to do what only governments and large corporations could do before. Our vision is to catalyze humanity’s growth both on and off the Earth. We’re breaking new ground.
Now is the time for us to gain access to these resources, and at the end the entire human race will be the beneficiary as we expand our reach beyond the Earth into the solar system. One asteroid may contain more platinum than has been mined in all of history. We’ve been searching for near-Earth objects mainly to assess the hazard of an impact on the Earth.
It turns out that most of these asteroids are not a threat to the Earth, but they do offer potential benefits. They are in Earth-like orbits that offer assessable resources that we can tap into, both for scientific knowledge and returning those strategic supplies to Earth. Resources from asteroids will add tens of billions of dollars annually to the global GDP.
Our plan for opening up the resources of the solar system is threefold. First, we’re going to identify all of the most valuable near-Earth asteroids– where they are, what they’re made of, and how to reach them. Second, we’re going to develop the technology and the capability to transform those resources into valuable materials. And third, we’re going to deliver those materials to the point of need, whether it’s a fuel depot orbiting the Earth or elsewhere in space.
Water sourced from asteroids will greatly enable the large-scale exploration of the solar system.
Our small and focused team will enable the commercial exploration of the solar system. We’re using experts who have gained their experience in NASA and the tech industry, and we’re keeping our goals simple and clear. Planetary Resources is applying commercial innovation to robotic space exploration. We have a need now for the knowledge of what’s on these asteroids.
There are potential resources in space, and the government is taking a scientific and measured approach to exploring them. We can really increase the knowledge that we get and the pace at which it comes back to us by involving commercial innovation and commercial visits to these asteroids. Planetary Resources will help ensure human prosperity by accessing the vast resources of space.
We are going to change the way the world thinks about natural resources.

Bold "Can Do" Engineers vs Timid Lowbrow Cowards
The basic operating rules of a Skunk Works are:
- The Skunk Works manager must be delegated practically complete control of his program in all aspects. He should report to a division president or higher.
- Strong but small project offices must be provided both by the military and industry.
- The number of people having any connection with the project must be restricted in an almost vicious manner. Use a small number of good people (10 percent to 25 percent compared to the so-called normal systems).
- A very simple drawing and drawing release system with great flexibility for making changes must be provided.
- There must be a minimum number of reports required, but important work must be recorded thoroughly.
- There must be a monthly cost review covering not only what has been spent and committed but also projected costs to the conclusion of the program. Don’t have the books ninety days late and don’t surprise the customer with sudden overruns.
- The contractor must be delegated and must assume more than normal responsibility to get good vendor bids for subcontract work on the project. Commercial bid procedures are very often better than military ones.
- The inspection system as currently used by ADP, which has been approved by both the Air Force and Navy, meets the intent of existing military requirements and should be used on new projects. Push more basic inspection responsibility back to subcontractors and vendors. Don’t duplicate so much inspection.
- The contractor must be delegated the authority to test his final product in flight. He can and must test it in the initial stages. If he doesn’t, he rapidly loses his competency to design other vehicles.
- The specifications applying to the hardware must be agreed to in advance of contracting. The ADP practice of having a specification section stating clearly which important military specification items will not knowingly be complied with and reasons therefore is highly recommended.
- Funding a program must be timely so that the contractor doesn’t have to keep running to the bank to support government projects.
- There must be a mutual trust between the military project organization and the contractor, with very close cooperation and liaison on a day-to-day basis. This cuts down misunderstanding and correspondence to an absolute minimum.
- Access by outsiders to the project and its personnel must be strictly controlled by appropriate security measures.
- Because only a few people will be used in engineering and most other areas, ways must be provided to reward good performance by pay not based on the number of personnel supervised.
How to Silence "Moon First" Advocates
In the August ’09 issue of Ad Astra, Denis Wingo — who has earned admiration as a tireless advocate of entrepreneurial space exploration — writes of a future landing expedition finding on the surface of the moon a large PGM boulder remaining from an asteroid impact. The purpose of the above Dragon Puff story is to point out that if a similar — albeit even much larger boulder — were found on the surface of an asteroid (they are studded with such structures) it would be much easier to transport the boulder to and use it at L1 than to engage resources for similar purposes on the moon. –Especially given that this could be done by entrepreneurs without either lunar overhead or heavy lift or even NASA approval.
