Yes, it would get the competition going again, but I think it may be China that have the determination and drive to pull that one off (if they keep to their schedule). Although the US has been known to pull a few rabbits out of their hats from time to time. But perhaps not as willing to take risks any more and that may be what is needed.

Sadly I agree with you. The loss of a couple shuttles was a very public event and I think that has taken some steam out of the drive to push the edge. Exploration is by its nature risky and you just can't make it completely safe. All the money and time you spend trying to eliminate (not reduce, eliminate) the risk factor only destroys budgets and delays advancement. I use the analogy of ships of explorers/settlers heading for the new world. Some ships never made it, some did but the settlements never took. Today we cross the oceans almost without thinking about it. Space is no different, just on a grander scale. But when those early settlers board the ships they will be taking the risk too. If our ancestors didn't do it we wouldn't have explored the world until the late 1900's. Nor would we have learned to build reliable ships as quickly.

  That's the risk - you make an unnecessary manned vehicle to launch satellites because you can get funding for it being 'our brave heroic astronauts' then when it goes wrong the same publicity comes back and bites you. Exploration of the West wouldn't have been possible if Nasa had been in charge: http://www.spacefuture.com/vehicles/how_the_west_wasnt_won_nafa.shtml http://www.spacefuture.com/vehicles/how_the_west_wasnt_won_n...

    Or, to put it bluntly, if you are not killing people, you are not pushing hard enough. I may be a weird person, but since when strapping yourself to a tank, the size of a building, filled with high explosives and riding it to orbit could be expected to be a safe thing? If astronauts wanted safety, they'd be accountants.

      The problem is that Nasa don't seem to have a reason for having astronauts there - other than without the astronauts there would be no interest and no Nasa. You could make it safer by replacing the Shuttle with an Apollo era capsule and sticking it on the front of every commercial ArianeV / Atlas IV launch. Wouldn't be any point in having the man there but it would be safer manned spaceflight.

        There is not much reason to have astronauts up there other than to have astronauts up there. You can do a lot of science with unmanned probes, you can launch satellites with unmanned rockets. OTOH, you can't repair the Hubble without meatware close to it. And no machine can tell you an inspiring story of adventure and exploration. And that's what NASA should focus on. Returning scientific data is important, of course, but stories of exploration are what inspire us.

        OTOH Hubble cost 3x as much to build because it had to be serviceable by the Shuttle and it's scientific use was greatly compromised by the orbit it had to be in. Each service mission cost (in real $) as much as building a non-shuttle HST. Compared to the Herschel space telescope I don't see Hubble as a great advert for manned space flight.

        You don't need a shuttle to repair a Hubble. Hubble's orbit was limited to what a shuttle could reach and the cost of repairing it compounded by the operational costs of the shuttle. You could send a repair crew on an expendable vehicle or, even better, launch a tow that could bring the satellite being serviced to the ISS and reinsert it into any desired orbit. The Hubble service missions greatly extended its useful life. I doubt Herschel will last as long.
