I wanted to bring up a quote that I've been pondering, but that has nothing to do with STS-107:
In the 1960s, President Kennedy set for us a very ambitous goal of going to the Moon. Somehow, we made it. We started with Ham's suborbital flight. Shepard followed in his footsteps. Glenn orbited Earth. Then was the Gemini program. Apollo 11's Eagle first landed on the lunar surface. Apollo 17 somberly left the Moon.When men are arrived at the goal, they should not turn back. -Plutarch
Since then, we've been orbiting a few hundred miles above Earth. While we're doing important experiments there, we've regressed. We've turned back. We established a long-term outpost in space. That can continue to do these important experiments, but I feel that we aren't doing as much as we should be doing in space. India is preparing a moonshot, and I applaud them. We should be planning to leave orbit again sometime soon.
According to Doctor Von Tiesenhausen, Mars is our planet. If we plan to go there, to permanently claim that piece of real estate, than we should be planning something. Another Moon landing? Perhaps to test equipment designed to go to Mars? We could estabish a Lunar colony.
Whatever we do, I feel we should be doing something more than just going in circles around a celestial marble. Does anyone else agree?
