The upcoming manifest includes two satellites for the Polarized Submillimeter Ice-cloud Radiometer (PolSIR) mission, designed to map ice clouds in the upper atmosphere, alongside a single craft for the Total and Spectral Solar Irradiance Sensor-2 (TSIS-2) project, which tracks solar intensity from orbit. Rocket Lab plans to execute the TSIS-2 mission early in 2027, with the PolSIR launches slated for after June of that year. These flights join the company’s existing commitment to launch NASA’s upcoming Aspera mission.

Chief Executive Officer Peter Beck noted that the Electron vehicle has established a track record for orbital precision over the past decade of NASA service. Following the announcement, Rocket Lab shares climbed 4.9% to $84.65 in after-hours trading, rebounding from a 5.5% decline during the regular session.
