We welcomed Dr. Martin Elvis to the program to discuss asteroid mining, commercial space, NASA & more. In the fist segment of our 91 minute discussion, after telling us about an asteroid being named after himself, Martin responded to my question about what he sees as our future in space. Dr. Elvis answered this question throughout both segments of today's program, making it clear that he sees solutions and development through astronomy & commercial space, not NASA. He began talking about our great space telescopes and the fact that the budgets are not there for such great tools and instruments to continue and be sustained, even to the tune of not being able to properly support the JWST. He had much to say on rising costs, budgets and when I asked about priorities, he said how much is the right amount to make space exploration, science, even HSF, a priority? What is their information worth compared to other worthy causes and uses for federal money? This analysis has led him to understand the future rests with commercial space to pay for space programs and ventures rather than relying on government funds. We then jumped into mining asteroids and the commercial potential of this emerging industry. He talked about initial small markets, maybe 10 worthy asteroids for mining or possibly doubling that number given uncertainties and risks associated with the formula for estimating the number of commercially viable asteroids. Do not miss this discussion as I am sure we will be referring to it frequently in future Space Show program discussions. The size and type of asteroid matter as you will hear with mining needing at least a 100 meter wide asteroid in the billion dollar range with Delta V requirements that are cost effective for getting to and from the target. Primarily we talked about water and PGM re asteroids. Listeners asked questions about trillion dollar asteroids per press reports, he looked them up and said the Delta V to get there, land, etc., was simply too high, a fact often ignored by articles referencing potential asteroid value. Doug emailed in about smaller asteroids, say 20 meters. Dr. Elvis had much to say about the smaller asteroids and their mining potential as well. Toward the end of the segment, we talked about regulatory and legal-illegal acts including the possibility of a competing company hijacking an asteroid for commercial purposes. Don't miss what he said about this. In the second segment, we started with a call from Doug. Doug and Martin had a log discussion as Doug wanted to compare mining potentials for asteroids and the Moon. Later, we talked more about space telescopes and Doug wanted to know if Hubble could be pointed in the direction of the sun for specific reasons. Later, we talked about Rosetta and P67. B John in Sweden sent in lots of questions about why not mine the Moon rather than an asteroid. Martin explained the value of going to an asteroid for mining and getting virgin scientific info over the Moon so listen to this discussion. Other topics included economics, depressing prices of PGM here on Earth by bringing this material back to Earth, zero G issues, Pluto, Kuiper Belt Objects and more.
