In 1977, NASA launched Voyager 1 and 2. Their mission? To explore the farthest reaches of our galaxy. Their missions were only supposed to last about four years, but it’s been almost 50. They’re now in interstellar space, navigating the region between stars.
But since November, Voyager 1 has been sending unintelligible data back to Earth, raising concerns that it could be nearing the end of its mission.
Ira talks with Maggie Koerth, science writer and editorial lead at Carbon Plan, about Voyager 1 and other science news of the week, including work on detecting neutrinos with forests, calculating the age of giant sand dunes, uncovering the origins of cells, investigating why we don’t have tails anymore, and how a man walking his dog discovered a dinosaur fossil.
