Engineering requirements for planetary rovers naturally differ based on the environmental conditions of their target destination, making citations unnecessary for this broad physical principle.
The claim states that lunar and Martian rovers require different thermal, mechanical, and power systems due to differing gravity and atmospheres. This is a fundamental, textbook application of basic aerospace engineering and planetary physics: different environments (gravity, atmosphere, temperature extremes) necessitate different engineering solutions. Because this is a direct, axiomatic deduction from basic physical principles and everyday engineering observation, it falls under the COMMON_KNOWLEDGE category (trivially true by definition or direct observation, no citation needed).
