Thirty-eight years ago today, Apollo 11 landed on the Moon. The dreams of countless generations had finally been realized. Unfortunately we failed to properly follow up on this triumph. We haven't been back to the Moon since December 1972. In fact we haven't left low Earth orbit since then. Many people thought we would have colonized the Moon by now, many of us think we should have. It is a hopeful sign that NASA's post shuttle plans do include a return to the Moon, and an eventual manned trip to Mars. We have the technology to colonize the Moon, we lack only the will.
