Mission
The 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.

Launch vehicle
Electron
Electron is a two-stage orbital expendable launch vehicle (with an optional third stage) developed by the American aerospace company Rocket Lab. Electron is a small-lift launch vehicle designed to launch small satellites and cubesats to sun-synchronous orbit and low earth orbit. The Electron is the first orbital class rocket to use electric-pump-fed engines, powered by the 9 Rutherford engines on the first stage. It is also used as a suborbital testbed (called HASTE) for hypersonics research.
