How about suborbital trips to about 1000km altitude as an intermediate step between hops to the edge of space and full-fledged orbital trips?<br />Delta V about 4500m/s<br />Time in 0G approx 15minutes.<br />A lot of the systems that later would be used for orbital craft can be tested in a more benign environment.<br />Plus....the view!<br />From 1000km out you will get a much better view of the Earth as a whole than from LEO. You will truly feel out in space! <div class="Discussion_UserSignature"> <p>http://asteroid-invasion.blogspot.com</p><p>http://www.solvengineer.com/asteroid-invasion.html </p><p> </p> </div>
