NASA is going back to the Moon, perhaps permanently, as seen in a new road map (image):

Four months after President Trump directed NASA to return to the Moon, the agency has presented a road map to meet the goals outlined in Space Policy Directive-1. The updated plan shifts focus from the previous "Journey to Mars" campaign back to the Moon, and—eventually—to the Red Planet.

"The Moon will play an important role in expanding human presence deeper into the solar system," said Bill Gerstenmaier, associate administrator of the Human Exploration and Operations Mission Directorate at NASA, in a release issued by the agency.

While the revamped plan may share the same destination as the Apollo program, NASA said it will approach the return in a more measured and sustainable manner. Unlike humanity's first trip to the Moon, the journey back will incorporate both commercial and international partners.

To achieve this, NASA has outlined four strategic goals:

  • Transition low-Earth orbit (LEO) human spaceflight activities to commercial operators.
  • Expand long-duration spaceflight activities to include lunar orbit.
  • Facilitate long-term robotic lunar exploration.
  • Use human exploration of the Moon as groundwork for eventual human missions to Mars and beyond.

This may be the best outcome for the space program. Let NASA focus on the Moon with an eye towards permanently stationing robots and humans there, and let SpaceX or someone else take the credit for a 2020s/early-2030s manned Mars landing. Then work on a permanent presence on Mars using cheaper rocket launches, faster propulsion technologies, better radiation shielding, hardier space potatoes, etc.

    The mathematical models for risk to health from radiation exposure were pretty crude due to lack of data. Basically, at one end of the scale they had Hiroshima and Nagasaki and at the other end the general population subjected to natural background in various regions. They drew a straight line from zero to nuclear war and interpolated. As time went on and the science became better, people were better placed to consider questions such as yours. Sometimes a big dose of something like gamma rays isn't that bad. Neutrons are the nasty ones. You don't want to breath in or eat alphas or betas. I don't know what the current thinking is. We had a simple mantra: time, distance and shielding.
