Space Lichens

moon_monkey writes "According to a report lichens - a composite of algae and fungi - can survive in space for up to two weeks. An experiment carried out by the European Space Agency saw two species of lichen carried into orbit and then exposed to the vacuum of space for nearly 15 days. These are the most complex form of life now known to have survived prolonged exposure to space. The experiment adds weight to the theory of panspermia - that life could somehow be transported between planets."

Have the also been able to survive reentry?

Because clearly having it survive in space is not in itself enough for life to migrate from planet to planet. Somehow it must survive reentry or else its a moot point.
