Back in the 50s and 60s there were a lot of proposals for manned space stations and spacecraft for various , mainly military purposes. With advances in computer technology, it became feasible- and much cheaper- to send unmanned spacecraft and satellites to accomplish the same missions.<br />What if computers were still heavy and unreliable? There would always be a need for heavy lift at the cheapest price possible and tons more people would need to go in space.<br />Is it possible that now we would have cheap access to space and colonies on the Moon or Mars? <br />Had the transistor never been developed. <div class="Discussion_UserSignature"> <p>http://asteroid-invasion.blogspot.com</p><p>http://www.solvengineer.com/asteroid-invasion.html </p><p> </p> </div>
