This is tangentially related to the thread. I'm putting it here because I couldn't find a better place.
China Aerospace Science and Technology Corporation (CASC) has cooperated with the Chinese national swimming team on sports performance. CASC used a wind tunnel to simulate the flow field experienced by swimmers and to measure their performance. The data was further analyzed to help the swimmers improve their performance.
Unlikely. This is a manned lander/rover and therefore weighs significantly more, not to mention the added complexity of hopping might be a step too far for an already complex piece of equipment that not only has to land on the moon and move around it but also has to sustain the humans onboard for extended periods.
