This week on SPEXcast we dive into the scientific instruments that drive new discoveries. NASA’s Development and Advancement of Lunar Instrumentation (DALI) selected 5 finalist projects for continued development. From neutron generators that can determine the composition of planets to lasers that can determine how old our solar system is, these new instruments promise exciting scientific potential if and when they fly on spacecraft in the future. NASA also selected the Atmospheric Waves Experiment as part of NASA’s heliophysics explorers program, which will go to the ISS to expand our understanding of airglow in Earth’s atmosphere.
