NASA Selects Rocket Lab to Launch Sun, Earth Science Missions

NASA has selected Rocket Lab to provide the launch service for both the agency’s PolSIR (Polarized Submillimeter Ice-cloud Radiometer) and Total and Spectral Solar Irradiance Sensor-2 (TSIS-2) missions. The two selections are part of NASA’s Venture-Class Acquisition of Dedicated and Rideshare (VADR) launch services contract.
