  • People have lift-off. Freeze-dried mouse sperm that spent nine months in space has successfully impregnated female mice and created healthy offspring. Despite growing discussion around space colonization, there are still big questions about the viability of human reproduction off Earth. Scientists say the high levels of radiation and low gravity could hinder conception or lead to abnormal development. Experiments have shown that fish and salamanders reproduce normally on space stations, hut research in mammals is scarce. A handful of studies in the 1980s found that male rats produced less sperm in space, but sperm quality was not assessed.
