To test the effects of space radiation on livng organisms we participated (23 June 2002) to the "BI.R.BA." mission (organised and granted by the Italian Space Agency, A.S.I), a flight with a stratospheric balloon, from Trapani-MILO (ASI Launch site) to Seville in Spain. Xenopus laevis embryos at different stages of development were exposed during flight.

Abstract
To test the effects of space radiation on livng organisms we participated (23 June 2002) to the "BI.R.BA." mission (organised and granted by the Italian Space Agency, A.S.I), a flight with a stratospheric balloon, from Trapani-MILO (ASI Launch site) to Seville in Spain. Xenopus laevis embryos at different stages of development were exposed during flight. Results on mortality show that younger embryos (16hr) flown on the balloon (B) are more sensitive to radiation exposure compared with older ones (40 hr and 6 days). The exposure during flight lowers the antioxidant potential in all the embryos, particularly in older ones.
