Agreed, but what about using a tether as a pilot project for artificial gravity generation?

Has the decision been made yet on whether the solid or liquid booster candidate will be used for the second generation SLS? They both seem to be very strong contenders.

Thanks for the answer, that makes a lot of sense.

One issue I have when landing in KSP from a Mars return in RSS is that you don't have a ton of control over where you land, since you are bound by safe re-entry constraints for the crew and capsule at such high speeds.

In reality, does that translate to having less control over where and when the crew lands in a Mars return flight land? In particular, might this force the crew to land at a time and place where conditions are sub-optimal for capsule recovery?

What were the deciding points to making the Orion capsule for water landings only, instead of ground landing like Soyuz? I would expect that would make partial capsule re-use easier.

Does NASA plan to test technology to generate artificial gravity for crew transit beyond Earth, such as was tested by teetering a Gemini capsule and Agena?
