Genetically enhanced human beings are believed to be a key component in the future of space travel. The field of genetic modification, which has already seen advancements in crops and animals, is now being explored for its potential in supporting human survival on Earth and beyond.
Scientists have successfully genetically modified pigs to grow organs like kidneys and hearts for human transplantation, as well as engineered crops to withstand challenging environmental conditions. This progress has sparked discussions about the necessity of genetic enhancements in humans to thrive in harsh space environments and on other planets.
At a recent event held by the British Interplanetary Society, the idea of using gene editing technology to prepare humans for interplanetary life was advocated. Astronomer Lord Martin Rees highlighted the importance of genetic modifications to help humans cope with atmospheric challenges, such as radiation exposure, that come with space exploration.
Advancements in technology now allow for the sequencing of entire genomes and precise editing of genes to alter their expression. One proposed application is the insertion of genes into humans that can aid in cleaning up radiation, potentially enhancing their ability to survive in space.
Furthermore, the concept of introducing genes that slow down the aging process and cell breakdown could prove beneficial for long-duration space missions. Researchers have drawn inspiration from tardigrades, microscopic animals known for their resilience to extreme conditions, including temperature, pressure, radiation, and starvation.
Laboratory experiments have shown that human cells with tardigrade genes inserted in them exhibited increased tolerance to X-ray radiation. While these findings are promising, extensive research is still needed to fully understand the implications of genetic enhancements in humans.
However, ethical considerations loom large in this field, as evidenced by the controversial case of a Chinese scientist who was jailed for creating the first gene-edited babies. As the scientific community continues to explore the potential of genetic modifications in humans for space exploration, the debate over the ethical and societal implications remains ongoing.
