Nereid, with its remarkable suite of scientific capabilities, will eventually change all that. “You can’t safely put a human-occupied submarine under an ice shelf. It’s too dangerous. There’s no escape route. But it’s perfect for underwater robot vehicles. Nereid can go there, complement existing technologies, and extend the scientific possibilities,” Whitcomb says.
