Robotics today and in the future are great for the advancement of our knowledge of the universe, but what good is this if we don,t step up and use our initiative,after all we are human, they,re not! The mistakes we will make will be far outweighed by the time lost waiting for astro boy to act. It is the unknown that makes us brave, that makes us progress. I don,t care if its chinese,japanese or indians getting there first, after all arn,t we all in this human race? As far as the unlikely cataclysm that may not occur, how many million, or is it billion collisions take place in the known universe that we don,t know about. All the more reason for us to get moving.

the thing i found most funny about human space exploration has to do with the Apollo launch rocket (saturn V). The engines used on that machine (huge things many times bigger then a house) are the most safe ever used according to the NASA tour guide i had (based on failure rates). However in testing NASA couldn't get the injection points right using scientific, mathimatical formula (ie. plans and engineers) So not wanting to give in to frustration NASA's scientist took a electric drill to there test engine and randomly drilled injection points and tested the results (to get the right thrust to heat to whatever else ratio). After doing this a few times they stumbled upon the correct mix of holes in the right places and the Saturn V had its main engine. The hole locations were recorded and replicated on all following engines and to this day remains the only NASA engine not to have failed. Well this was the story told to me by a NASA tour guide leave it up to you to decide if its true or not. But its sounds like NASA haha.

They wouldn't be so bold or have that initiative anymore. A NASA employee, now, would be sweating over the protocols to put in triplicate forms to ask for a change to the plans, then they'd ship the whole caboose to another facility and have it locked away in a clean room for 6 months whilst the planning committees and the financial committees wrangle over how much it was going to cost and if they could maybe cut some corners without compromising safety, which they'd inevitably would do. Then after 6 Congressional appropriation committees, 6 heads of NASA meetings and 6 more planning committee meetings, the President would sign an executive order to can whatever program it was they were working on, then slash the budget of the agency by 10-20% and tell them to do more with less. Sounds like a familiar scenario, doesn't it??

The old days were the days when they had decent administrators in NASA and everyone was willing to take the risks needed to get the work done and the men/machines/probes in space. Too many bean counters and too many yes men in the organisation, now. Has been for far too long. 0.5 of 1% of the budget, or less, they spend on the space program. They spend more on Big Macs and advertising for the Super Bowl than they do for something infinitely better for everyone than cholesterol, obesity and mindless half time entertainment at a footy match.

No wonder they're going backwards, and fast. Maybe they should do what former NASA administrator Dan Goldin said he'd do if they found an Earth-like planet orbiting around either star of Alpha Centauri. At the rate they're back pedaling now, if they got out and pushed a Space Shuttle in the forward direction, they'd prove Einstein wrong for sure, because they'd instantly jump to Warp 9!!

21.4 hours to Alpha Centauri....not bad going

The scary thing i heard from the guide was also the sadest. That after the apollo missions finished up (and the need for the main booster engines with it) they dismantled all the surplus engines bar 6. Five are still usable on the "display" in Florida (a saturn V on its side is a sight to see) and the 6th they filled with concrete and put on display (this was the original test engine i believe). These engines remain to this day the only ones with enough thrust to lift heavy (human?) load to break orbit and reach the moon (with a human crew and supplies on board). So at the moment unlike most of the late 60's early 70's humans can't achieve escape volocity. The really really sad thing is the guide said they had lost the plans on how to make the engines and the only people with the 'experience' in making them are now all around 80 once they kick the bucket we will completely loose this ability.

Someone better find a diylithum crystal quick fast

One good point the spokesman hit on as a result of the Obama’s new space plans, or what I understood to be; was that Nasa would be forced to better spend the money. Hopefully that might spark a little old fashioned ingenuity. I had no idea about the drilling holes thing...wow...good work

rrr, forget the middle east and redirect the money to space, mine the moon. Find a mineral rich moon, asteroid etc and mine it. Surely the money spent on the middle east is better spent on reaching for the stars then trying to control something which cannot be controlled. Seed mars, venus with life from earth....Deep canyons could hold an atmosphere adjustable for earth life.
