to save weight, there were no seats for the men. they would stand, loosely held in place by straps. in front and on either side of them were control panels for the lm’s guidance, communication, environment and propulsion systems. on the left side, there was a window by which commander could look out to steer the lm. overhead in the middle section was the of diameter hatch where the astronauts transferred to and from the command module when two vehicles were linked. lm’s ascent rocket to meet command module was below the deck of the midsection. although ascent rocket was small, it was sufficient because the moon’s weak gravity – one-sixth that of earth’s – meant that the lm would not require a strong push to rise from the lunar surface.
