The Odysseus lunar lander, nicknamed “Odie” or IM-1, is trying to become the first US-made spacecraft to successfully touch down on the moon in five decades. "It's white-knuckle time" for the robotic explorer, the NASA chief said, as engineers work to overcome a navigation issue.
It comes after a failed US lunar landing mission last month that ended with the Peregrine spacecraft burning up in the atmosphere as it careened back toward Earth 10 days later.
