I'm sure glad that the presenter balanced his presentation by discussing artificial gravity via tethering & spin-up. I've listened to too many presentations that discuss the litany of health problems caused by weightless without giving fair consideration to what could be a fairly solution.
And since NASA doesn't intend to send humans to Mars until the 2030s, significant funding for artificial gravity habitats for interplanetary travel really doesn't have to occur until the early 2020s.
"The knowledge that we have now is but a fraction of the knowledge we must get, whether for peaceful use or for national defense. We must depend on intensive research to acquire the further knowledge we need ... These are truths that every scientist knows. They are truths that the American people need to understand." (Harry S. Truman 1948).
"The greatest long-term threat to U.S. national security is not terrorists wielding a nuclear or biological weapon, but the erosion of America's place as a world leader in science and technology."
Gordon England: 1st Deputy Secretary of Homeland Security and former Secretary of the Navy

I agree. There are solutions.
And since NASA doesn't intend to send humans to Mars until the 2030s, significant funding for artificial gravity habitats for interplanetary travel really doesn't have to occur until the early 2020s.
