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 OrbitThe PoISIR (Polarized Submillimeter Ice-cloud Radiometer) mission will help provide a better understanding of ice clouds that form at high altitudes throughout tropical and subtropical regions. Consisting of two small satellites, both of PoISIR’s 16U CubeSats have a scientific instrument designed to measure a specific spectrum of electromagnetic radiation, which will determine how the amount of ice in tropical clouds rises and falls during the day, as well as how the ice changes connect to larger storms. The instruments also will help determine how ice clouds affect sunlight and heat radiation throughout the day. The pair of CubeSats will fly in orbits separated by several hours to observe the pattern of cloud ice content changes over a day. This information will help researchers make more accurate weather predictions.

Low Earth OrbitNZSA Venus Mission is a small direct Venus entry probe with a single 1 kg low-mass, low-cost autofluorescing nephelometer riding on a satellite bus based on the Photon Upper stage of the Electron rocket. The probe mission will spend approximately 5 minutes in the Venus cloud layers, 48-60 km above the surface, collecting in situ measurements to search for organic molecules in cloud particles and constrain particle composition.
