NASA Selects Proposals to Study Galaxies, Stars, Planets

NASA has selected six astrophysics Explorers Program proposals for concept studies. The proposed missions would study gamma-ray and X-ray emissions from clusters of galaxies and neutron star systems, as well as infrared emissions from galaxies in the early universe and atmospheres of exoplanets, which are planets outside of our solar system.

Cassini to Begin Final Five Orbits Around Saturn

NASA's Cassini spacecraft will enter new territory in its final mission phase, the Grand Finale, as it prepares to embark on a set of ultra-close passes through Saturn’s upper atmosphere with its final five orbits around the planet.

NASA Selects Proposals to Study Sun, Space Environment

NASA has selected nine proposals under its Explorers Program that will return transformational science about the Sun and space environment and fill science gaps between the agency’s larger missions; eight for focused scientific investigations and one for technological development of instrumentation.
