NASA’s Cassini spacecraft has transmitted thousands of images back to Earth while chronicling its voyage through the solar system and into Saturn’s orbit. But its 20-year mission is nearing its end. The spacecraft will plunge into the ringed planet’s atmosphere Sept. 15, sending data for as long as it can until it disintegrates.

To some, space science may not seem to have obvious relevance. When it comes to breakthrough discoveries that alter the course of events on Earth, however, the end goal of a space mission is only the tip of the iceberg. Space science regularly spurs valuable advancements that help humans live long and prosper at home, and it is responsible for such innovations as improved computer software and new imaging technologies. Furthermore, strength in areas related to science, technology, engineering and mathematics remains a key indicator of a country’s future competitiveness. Projects like the Cassini mission are a valuable opportunity to captivate the minds of younger generations, leading them to mathematics, the sciences, and beyond.

Cassini captured this image of Titan, Saturn’s largest moon, in ultraviolet and infrared wavelengths. On Jan. 14, 2004, the Huygens probe landed on Titan, setting the record for the greatest distance from Earth that a spacecraft has landed.

Cassini captured this high-resolution glimpse of the dark side of Saturn’s moon Iapetus — and, for the first time, the bright side as well — on Sept. 10, 2017. The dark region on Iapetus is called its leading hemisphere, while the bright region is called its trailing hemisphere.
