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 L1Dragonfly is NASA's 4th New Frontiers program mission that will send a robotic rotorcraft to fly within the atmosphere of Saturn's moon Titan to sample materials and determine surface composition in different geologic settings, advancing humanity's search for the building blocks of life. The craft is a large quadcopter with double rotors with mass of about 875 kg, featuring rotors of 1.35 m in diameter. It can fly through several kilometers within an hour and will perform 1 flight per Titan day (~16 Earth days). During the planned 3.3-year mission, Dragonfly is expected to cover distance up to several hundred km. Dragonfly will use a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) to power its instruments. The planned science instrument suite is: * DragonCam: Camera Suite * DrACO: Drill for Acquisition of Complex Organics * DraMS: Mass Spectrometer * DraGNS: Gamma-ray and Neutron Spectrometer * DraGMet: Geophysics and Meteorology
Heliocentric N/AExoMars 2028 is a second mission of two-part European Space Agency astrobiology project to search for evidence of life on Mars. The primary objective is to land the rover at a site with high potential for finding well-preserved organic material, particularly from the very early history of the planet. The rover is expected to travel several kilometers during its mission. The European rover will be the first mission to combine the capability to move across the surface and to study Mars at depth. It will collect samples with a drill down to a depth of 2 m and analyze them with next-generation instruments in an onboard laboratory. Underground samples are more likely to include biomarkers, since the tenuous martian atmosphere offers little protection from radiation and photochemistry at the surface.
Heliocentric N/AEchoStar 26 is a direct broadcast satellite, built on the proven Maxar 1300 series platform, which will deliver content across DISH TV customers across all 50 U.S. states & Puerto Rico. It will be equipped with a high-power, multi-spot beam payload, allowing DISH to provide high-quality content to its customers.
Geostationary Transfer OrbitGRACE-C (Gravity Recovery and Climate Experiment-Continuity) is a successor to the original GRACE and GRACE-FO missions, providing month-to-month changes of Earth's gravity field to track water movement and surface mass changes across the planet, monitoring variations in ice sheets, glaciers, underground water storage, soil moisture, and sea levels. GRACE-C consists of two identical satellites flying around 200 km apart at an orbit altitude of 500 km with an inclination of 89 degrees. Each satellite will measure approximately 3 x 2 x 1 meters and weigh around 600 kg. This launch will also carry ride-sharing small satellites via Exolaunch.
