F. Hoyle et al., The viability with respect to temperature of micro-organisms incident on the Earth's atmosphere, ASTRO SP SC, 268(1-3), 1999, pp. 45-50
Using laboratory measurements of the resistance of E. coli to flash-heating
, it is shown that a large fraction of interplanetary micro-organisms in pr
ograde orbits could be added to the Earth without losing viability due to b
eating by the atmospheric gases.
