NASA will send a probe to the sun
NASA’s Parker Solar Probe 2, which cost around $1.5 billion, got within 15 million miles of the sun’s surface in November. And next year, it’s going to get even closer. There are two planned perihelions—a scientific term for the moment of closest approach—in April and September. As a NASA director said in a statement, “This probe will journey to a region humanity has never explored before.”
