TrumpSpace: #JourneyToMars Or #BackToTheMoon For NASA?

NASA's next stop--Mars or the Moon? John Grunsfeld and Paul Spudis argue for and against Mars and the Moon, Ars Technica

"Both men agree on one point: with NASA's limited funds, even before possible cuts under a Trump administration, the space agency can't do both. Sending astronauts to the Moon and establishing a colony would push human exploration of Mars into the second half of this century. Alternatively, making a direct push toward Mars would preclude any meaningful human exploration of the Moon. A choice must be made. For the last six years, NASA has continued developing a deep space capsule, Orion, as well as begun construction on a large new rocket, the Space Launch System, as the foundation of an exploration program. NASA has promoted a "Journey to Mars," but in reality the space agency has taken no definitive steps to preclude either a Moon or Mars pathway. That decision will have to be made soon. Within the next four years or so, the space agency must start designing and building specific hardware, for landing and living on either the Moon or Mars."
