SPACE SCIENCE

摘要

The budgets for space science and space exploration at NASA may be comparable in size, but that's where their similarity ends. Human flight and the hardware needed to make it happen get most of the attention from Congress and the public, thanks in part to the clout of the aerospace industry and the popular appeal of astronauts. But scientific missions, such as Hubble and the Mars Curiosity rover, have racked up the biggest achievements in recent years. The next president will be challenged to find a way to keep both sectors healthy, and it promises to be a tall order for either man.
