QUESTION: How many G's did you experence going up in space and how do you cope with it? ANSWER from Guy Beutelschies on March 27, 1997: Both Mars Global Surveyor and Mars Pathfinder are unmanned. The spacecraft, however, did experience 9 G's during launch. We knew about this ahead of time so we designed the structure to withstand it. Guy Beutelschies: Mars Pathfinder Flight Engineer
