at least I think we should, I know how long of a process it was for Hubble to get the ultra deep field picture,<br />several months, hundreds of orbits, catching one photon per minute,<br /><br />but we really need to map the whole sky, maybe spending 10% less time per location, to get more time available on other locations.<br /><br />Is mapping the entire ultra deep sky a current plan? or am I the only one who would like to see that done?<br /><br />we really should build another Hubble also, as a matter of fact we should build 2 of them, It's probably<br />less costly per scope to build 2 when one is built, a production line of Hubbles is what we need, they're<br />self proven and useful and long lasting, and I'm not sure how much longer Earth's only Hubble will last,<br />and there's still way too much to map.<br /><br /> <div class="Discussion_UserSignature"> </div>
