C.13 Science Transport and Robotic Innovation for Deployment and Exploration (STRIDE) solicits proposals from U.S. industry to conduct design studies of advanced robotic surface and aerial mobility systems with payload transportation and deployment capability for Mars surface operations, and, where applicable, early-stage prototyping of hardware for the same

Scientists now propose that the vertebrate eye traces back about 560 million years to a cyclopean invertebrate with a single patch of light-sensitive cells on the top of its head. That primitive organ likely tracked day and night and helped the animals orient themselves while they poked their heads out
