NASA's Near-Earth Object (NEO) Surveyor mission is designed to help advance planetary defense efforts to discover and characterize most of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit. These are collectively known as near-earth objects, or NEOs. NEO Surveyor consists of a single scientific instrument: a 50 centimeter (nearly 20 inch) diameter telescope that operates in two heat-sensing infrared wavelengths. It will be capable of detecting both bright and dark asteroids, which are the most difficult type to find.
Heliocentric L1The JPSS constellation of satellites collects global multi-spectral radiometry and other specialized meteorologic, oceanographic, and solar-geophysical data via remote sensing of land, sea, and atmospheric properties. These data support NOAA’s mission for continuous observation of Earth’s environment to understand and predict changes in weather, climate, oceans, and coasts to support the nation’s economy and protect lives and property. NASA uses the instruments aboard the JPSS satellites to continue decades of Earth science research for the betterment of humanity. JPSS-4 carries the NASA Earth Venture mission Libera, an instrument to improve our understanding of trends in Earth’s energy imbalance and our changing climate.
Sun-Synchronous OrbitLuna 26 (also named Luna-Resurs) is a planned lunar polar orbiter, part of the Luna-Glob program, by the Russian space agency Roscosmos. In addition to its scientific role, the Luna 26 orbiter would also function as a telecommunication relay between Earth and Russian landed assets. The scientific payload on board the orbiter is composed of fourteen instruments that will be fabricated by Russia. The payload will study the lunar surface and the environment around the Moon, including the solar wind, and high-energy cosmic rays. Luna 26 will also scout sites for the planned Luna 27 landing mission. Luna 26 is the second mission of Russia's new lunar program, which includes the launch of Luna 27, a heavy lander that will study the composition of the lunar soil by collecting several samples. Luna 28, a lunar samples return mission, will be the first to return samples at lunar temperature, and will serve as a demonstration for a future Martian samples return mission. Finally, Luna 29 should land a heavy lunar rover on the surface.
