NASA Is Giving Up on Their Mars Mole | SciShow News

The video discusses the nature of binary star systems, highlighting that many stars have companions. It details the discovery of extragalactic binaries using the Sloan Digital Sky Survey, focusing on systems in the Draco dwarf Galaxy and the Small Magellanic Cloud. The study of these systems helps understand star masses and orbits, and their role in Type 1A supernovae, which are crucial for measuring cosmic distances. The video also covers the challenges faced by NASA's Insight Lander on Mars, particularly with its Mole instrument, which struggled with unexpected soil conditions. Despite setbacks, the mission provides valuable insights into Martian geology.
