Mars. In dramatic contrast to the moon, Mars has all the elements and substances, in abundance, necessary for life and industry, including, crucially, water. It has an atmosphere shielding the surface from solar flares and other radiation. By incredible luck, it has a 24-hour day/night cycle like Earth, and its soil is a viable medium for plant growth, so large, cheap, inflatable greenhouses are practical, which is crucially important. People need farms. Over the long run, Mars can be "terraformed," or made to be more Earthlike, with a thicker atmosphere, a warmer climate, and even a shirt-sleeve environment. Mars has as much land as all Earth's continents combined, and it's all open and available. It is truly the next frontier waiting for humanity.
And we can get there right now with boring, current technology at reasonable cost. No need to wait for a distant exotic someday. If we focus on going there directly, without distractions and diversions such as orbital/lunar spaceports or futuristic propulsion, and if we "live off the land" by manufacturing water, oxygen and return fuel from abundant and cheap local resources using simple and reliable 19th-century-technology chemical reactions, we can afford a significant program of Martian exploration, with a new crew launched every two years, at about $50 billion over 10 years, which accounts for massive government cost overruns and is a fraction of the current NASA budget of $17 billion a year, which is itself less than 1 percent of federal spending. Truly a small price to pay to give humanity a second world.
