The Space Shuttle will once again be leaving for the International Space Station on Saturday morning, assuming the weather and equipment cooperate.<\/p>\n
I get puzzled by many things. One question that I\u2019ve never really quite fathomed goes like this: “Given the success of the unmanned space probes, such as the twin rovers on Mars, or Cassini and Huygens at Saturn and Titan, or the Hubble Space Telescope, what is the point of sending people into space? People are expensive. They have to be fed, and they require complex life support systems. Can\u2019t we get enough science just from our unmanned probes? They only cost a fraction of a human crewed system, they don\u2019t eat, and they don\u2019t need life support.”<\/p>\n
While it is true that unmanned spaceships are less expensive, and while it is certain that they have been marvelously successful, I\u2019m not sure why some conclude from that, that we have no reason to be sending people out there, too. <\/p>\n
It\u2019s like asking your neighbors, after they come back from their summer vacation, \u201cWhy did you waste all that time and gas actually going to see the Grand Canyon, when lots of people have already been there and brought back perfectly good videos and photographs? You really thought you could do any better than everyone else who has gone there before? Think how much you\u2019d have saved if you had just ordered a DVD off of Amazon! No traffic to fight, no bad weather to stand in, and you wouldn\u2019t have had to worry about you or your children falling into that big hole. Quite a dangerous place, after all.\u201d<\/p>\n
Those who think sending people into space is wasteful apparently believe that robots are the equal of humans, or perhaps even better than humans. So I have to wonder, would they likewise suggest to your boss that you be replaced with a machine? After all, a machine would be a lot cheaper in the long run. The machine won\u2019t get sick. It won\u2019t expect to get paid. It won\u2019t take coffee breaks. And it would never think of wasting all that time on a trip to the Grand Canyon.<\/p>\n
I just don\u2019t understand how someone can imagine sending robots is enough. Don\u2019t you believe that a human being on Mars might be a bit more versatile and a bit more valuable than a small wheeled vehicle that can travel only a few dozen feet a day? Not to denigrate the robot, but why do those who ask the question seem so pleased to underestimate human capabilities?<\/p>\n
Humans are a bit more adept than machines, and more easily adapt themselves to the unexpected. And even with our machines that we send into space, they are hardly autonomous. They require a lot of careful handling by a team of scientists back on Earth, who work feverishly night and day to try to keep things working, who not infrequently have to try to puzzle out what might have gone wrong a hundred million miles away and hope that their radioed commands will save the day. If there were people on the other end, it wouldn\u2019t be nearly as difficult. \u201cHey Joe, could you try plugging that cord into the power supply? It seems to have fallen out.\u201d<\/p>\n
I love computers and use them every day; but I\u2019m painfully aware of their limitations. When I search my hard drive or the web for a specific file, I\u2019ve got to be very careful about how I word my request and how I spell everything. Otherwise, I am simply not going to get what I\u2019m looking for. How intelligent is your computer at home, after all? Do you really want to leave the exploration of the universe up to that thing on your desk?<\/p>\n
Why go to watch the Super Bowl in person? Isn\u2019t seeing it on TV just as good, or even better than being there in person? Why would you be excited if you won free tickets to see the game? If you went to the game in person, you\u2019d have to sit on hard benches, sit in the sun or cold or rain, struggle with parking, pay an arm and a leg for bad food and tiny drinks, and have to put up with the noise of a stadium filled with people. And then you\u2019d just be squinting down at the ant-like figures on the field far below, in desperate need of binoculars just to figure out what was happening. So just stay home, where you can stretch out comfortably on your nice soft couch, with close up views, and instant replay, and all the munchies you need.<\/p>\n
It is, quite frankly, not nearly as stirring to watch R2D2 stride across an alien landscape as watching a human being do it. Our memories of Neil Armstrong taking that first small step should be enough to remind us that there is much more to exploration and space travel than just the science. Odd how that part of the equation doesn\u2019t figure in to those who question the need for people.<\/p>\n
And if all the people who have already signed up to ride on Virgin Galactic\u2019s SpaceShipTwo is any indication, most of us would jump at a chance to go into space ourselves. Virtual reality and video games and movies and TV are fine, but we\u2019d really like to experience it. We kind of like reality, I think. Isn\u2019t it a good enough reason to send people into space just the simple fact that we want to go? <\/p>\n
But, if you think watching the Super Bowl on TV is good enough, then please send me your tickets. I\u2019ll be happy to endure all the hassles of reality in your place.<\/p>\n
