Rocket Lab Corporation (NASDAQ: RKLB) has been selected by NASA to conduct three Electron rocket launches for two separate science missions, the company announced June 25, 2026, based on a press release from the Long Beach, California-based company.

Rocket Lab will carry out two back-to-back Electron launches for NASA's PolSIR mission from Launch Complex 1 in New Zealand no earlier than June 2027. A third Electron launch, for NASA's TSIS-2 mission, is scheduled from the same site in early 2027.

The PolSIR (Polarized Submillimeter Ice-cloud Radiometer) mission will deploy two identical CubeSats into separate 52-degree inclination, non-sun synchronous orbits to study ice cloud formation, variability, and ice content in the tropics and sub-tropics. Data from the mission is intended to improve Earth system weather prediction models.

The TSIS-2 (Total and Spectral Solar Irradiance Sensor-2) mission will launch a single satellite to measure the Sun's energy output at the top of Earth's atmosphere across ultraviolet, visible, and infrared wavelengths. According to the press release, NASA booked the TSIS-2 launch within seven months of contract signing to meet time-sensitive mission requirements.

Rocket Lab founder and CEO Sir Peter Beck said: "Electron has become synonymous with reliability, precise orbital accuracy, and on-demand launch capability and we've been delivering this for NASA missions for almost a decade."

Rocket Lab also noted additional upcoming NASA missions on its manifest, including the Aspera astrophysics mission and the LOXSAT mission, the latter of which will use Rocket Lab's own Photon spacecraft to demonstrate in-space refueling technologies.
