The Small Mars Chamber provides a ‘clean’ controlled environment, with dedicated solar illumination, well-suited to instrument qualification and astrobiology experiments. The controls permit automated variation of the environment, such as thermal diurnal cycling etc.<\/p>\n\n\n\n

Description<\/h2>\n\n\n\n

The Small Mars Chamber is a partiallyautomated environmental chamber system, allowing automated simulationof the martian surface environment. It is0.7 m in diameter and 1.2 m in length, capable of testing large instruments\/structures and exposure of large biological samples (-70\u00b0C to +110\u00b0C at 6 mbar CO2<\/sub>\/N2<\/sub> atmosphere). The key capability of this chamber is the ability to automate pressure and temperature, allowing thermal cycling tests to be easily performed. Inaddition, it can also be used for Dry Heat Microbial Reduction (DHMR) sterilisation tests, providingsustained temperatures of >110\u00b0C for continuous periods. The chamber also has illumination ports for adedicated lamp source, which provides simulation of martian UV conditions.<\/p>\n\n\n\n
