Survival on Mars
Brevundimonas is one of few bacteria showing high survival rates under simulated Martian conditions.
Results from one of these experimental irradiation experiments, combined with previous radiation modeling, indicate that Brevundimonas sp. MV.7 em-placed only 30 cm deep in Martian dust could survive the cosmic radiation for up to 100,000 years before suffering 10
6 population reduction.
