Given the challenges of space, 'I think simpler animals, such as insects or crustaceans, will likely be more robust,' he said. In these conditions, small animals, maybe mice, and aquatic life would likely be the best bet, he said.Ĭatling gave a similar response. The altered gravity could affect muscle and bone development, leaving Mars animals unable to stand or walk properly. The best scenario is that animals would develop on Mars and the moon just as they do on Earth, but there's no data on that yet, McKay said.
