摘要：

Martian caves are regarded as one of the most interesting locations in which to search for life on the planet. Data obtained during the MARS2013 expedition at Hamar Laghdad Ridge in the Tafilalt region of Morocco indicate that even small cavities can display thermal behavior that is characteristic for caves. For example, temperature in a cavity equaled 14 degrees C +/- 0.1 degrees C before sunrise, which was higher than the temperature of the ambient air (10 degrees C +/- 0.1 degrees C) and proximate rocks (9 degrees C +/- 0.1 degrees C) at the same time. Within 30min after sunrise, when the temperature of surrounding rocks corresponded to 15 degrees C, this thermal relationship reversed. Measurements were conducted under simulated spaceflight conditions, including near-real-time interpretation of data that were acquired in a complex flight planning environment. We conclude that using ground-based thermal contrast measurements, in 7-14m band before and after sunset, is an effective method for Mars astronauts to identify caves, possibly superior to usage of space-based or ground-penetrating data.
