In his <a href=\"http:\/\/www-rohan.sdsu.edu\/faculty\/vinge\/longnow\/\">\u201cWhat if the Singularity does not happen?\u201d<\/a> talk for the Long Now Foundation in San Francisco, Vinge calls the continuing pursuit of space under current-day launch costs as a \u201csham\u201d:<\/p>\n<blockquote><p>Well, launch to LEO still runs $5000 to $10000\/kg. As far as I can tell, the new <a href=\"http:\/\/www.nasa.gov\/mission_pages\/exploration\/main\/index.html\">Vision for Space Exploration<\/a> will maintain these costs. This approach made some sense in 1970, when we were just beginning and when initial surveys of the problems and applications were worth almost any expense. Now, in the early 21st century, these launch costs make talk of humans-in-space a doubly gold-plated sham:<\/p>\n<ul>\n<li>\n<ul>\n<li>First, because of the pitiful limitations on delivered payloads, except at prices that are politically impossible (or are deniable promises about future plans).<\/li>\n<li>Second, because with these launch costs, the payloads must be enormously more reliable and compact than commercial off-the-shelf hardware \u2014 and therefore enormously expensive in their own right.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>I believe most people have great sympathy and enthusiasm for humans-in-space. They really \u201cget\u201d the big picture. Unfortunately, their sympathy and enthusiasm has been abused.<\/p>\n<p>Humankind\u2019s presence in space is essential to long-term human survival.<\/p>\n<p>That is why I urge that we reject any major humans-in-space initiative that does not have the <em>prerequisite<\/em> goal of much cheaper (at least by a factor of ten) access to space.<\/p><\/blockquote>\n<p>We at Lifeboat Foundation wholeheartedly agree. A self-sustaining space station, which could weigh thousands or even millions of tons (the International Space Station weighs 235 tons), must be built out of components either harvested in space or launched for costs less than an order of magnitude than the current costs. We\u2019re coming to a point in history where these expensive launches are just a waste. Why invest billions in going to Mars when we can\u2019t even get out of our own atmosphere for anything less than millions of dollars? We have to put investment towards better approaches to launch. Superconducting maglev or mass driver approaches likely hold the key.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mathematician and science fiction author Vernor Vinge, who coined the term \u201cSingularity\u201d, is an advocate of the Lifeboat Foundation\u2019s mission: get some people off the Earth and get them self-sustaining as soon as possible, as an insurance policy against existential risk.
