阿波罗11的探测杆长度是1.7米，落月速度1.7ft/s.差不多是0.5m/s，并不快

Landing on the surface occurred at 102:45:39.9 with negligible forward velocity, approximately 2.1 ft/sec to the crew's left, and 1.7 ft/sec vertically. Body rate transients (motions after first footpad touchdown) occurred and indicate that the right and forward landing gear touched almost simultaneously, giving a roll-left and a pitch-up motion to the vehicle. The left-directed lateral velocity resulted in a slight yaw right transient at the point of touchdown. These touchdown conditions, obtained from attitude rates and integration of acceleration data, were verified qualitatively, by the at-rest position of the lunar surface sensing probes and by surface build up around the rims of the footpads ( as photographed by the astronauts during the EVA).

【 在 Zinux 的大作中提到: 】
: 这些都可以通过物理去解释，而不是拍脑袋的觉得越重就得压痕越深。
: 考虑压痕不能只考虑质量的，还有着陆速度、压强、接触角度、月面硬度等。
: 1、嫦娥是采取3米高自由落体，靠支撑结构缓冲。
