Space Telescopes, Struggles, and Stardust
Today we're going to talk about some issues and updates concerning two pivotal missions in the field of space science. First on our agenda is the European Space Agency's (ESA) Euclid space telescope, which launched in July. Its mission is to probe the enigmatic dark universe—made up of dark energy and dark matter—but it's facing some technical difficulties that we'll go over. Second, we'll discuss NASA's OSIRIS-REx mission that has returned a sample capsule from an asteroid, and the interesting things it's already revealing.
