Astronauts driving a vehicle around the landscape of the moon must not only face dangers related to zero gravity and falling into craters, but also the problem of extreme fluctuations in temperature. The lunar environment oscillates between blistering highs of 127°C (260°F) and frigid lows of -173°C (-280°F).
