The Total and Spectral Solar Irradiance Sensor 2 (TSIS-2) is a satellite designed by NASA to measure the Sun's energy input to Earth. TSIS-2 comprises two instruments, the Total Irradiance Monitor (TIM), and the spectral Irradiance Monitor (SIM). TIM measures total brightness and SIM measures spectral irradiance over a wavelength range that includes 96% of the energy in the solar spectrum. Both instruments are similar to those used for the TSIS-1 mission onboard the International Space Station.
Sun-Synchronous OrbitNASA'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.
