Training Difficulties

One of our Cosmosphere campers asked what the most rigorous part of my training has been? The answer is that all of it is rigorous in that you must be precise. The consequences on ascent or entry, during robotics operations, or during an EVA can be dire so the expectation in training is that they must be done right. The resources and time available to accomplish the task are limited, so in addition to being precise, you must be efficient. Because of this the rigor isn't defined necessarily by absolute "right ways" but by repetitive accomplishment of the task within bounds where you can gain insight and efficiency so that the end result is the successful timely completion of the mission.
