Xenopus laevis emryos at different stages of development were exposed during flight. Results on mortality show that younger embryos (16 hr) 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.Space Flight: Life Scienceconference paper54dcce088580fe1368eeb078
