TLDR
- RKLB rebounds after NASA selects Electron for three 2027 launches.
- NASA taps Rocket Lab for PolSIR and TSIS-2 science missions.
- Electron gains new NASA work as RKLB recovers in after-hours trade.
- Rocket Lab adds three NASA missions to its growing Electron pipeline.
- RKLB stock rises after hours on fresh NASA launch contract momentum.
Rocket Lab (RKLB) shares secured three NASA launch assignments, supporting an after-hours recovery in RKLB shares following Thursday’s regular-session decline. RKLB closed 5.53% lower at $80.69, then rebounded 4.35% to $84.20 following the announcement. The contracts expand Rocket Lab’s NASA pipeline and add three Electron missions beginning in early 2027.
NASA Selects Electron for Three Launches
NASA selected Rocket Lab to conduct two launches for PolSIR and one separate launch for the TSIS-2 mission. Rocket Lab will operate all three missions from Launch Complex 1 in New Zealand during 2027. The selection reflects Electron’s established launch record, deployment accuracy, and ability to support demanding schedules.
Rocket Lab plans the TSIS-2 launch for early 2027, only seven months after the contract signing. NASA required a fast schedule because the mission carries time-sensitive scientific and operational objectives. Electron provides a dedicated option for small spacecraft without depending on larger shared missions or extended rideshare timelines.
The two PolSIR launches will occur back-to-back, no earlier than June 2027. Each Electron rocket will deploy one identical CubeSat into a separate orbit. NASA designed the mission around precise orbital spacing and repeated observations throughout changing periods.
PolSIR Will Examine Tropical Ice Clouds
PolSIR will study high-altitude ice clouds across tropical and subtropical regions using polarized submillimeter radiometers. The mission will examine cloud formation, daily changes, and the amount of ice inside those clouds. NASA will use the findings to improve Earth system models and strengthen global weather predictions.
Each CubeSat will enter a 52-degree inclination orbit with non-sun-synchronous positioning. This structure will allow researchers to compare cloud behavior across daily, seasonal, and annual cycles. The separate orbital paths will also provide broader observation times over targeted regions.
Electron’s deployment accuracy will support PolSIR’s requirement for two precisely separated orbital paths. Rocket Lab says Electron can place payloads within meters of their intended deployment targets. That capability gives NASA greater control over observation timing and the collection of comparative scientific data.
TSIS-2 Expands Rocket Lab’s NASA Pipeline
TSIS-2 will measure solar brightness at the top of Earth’s atmosphere across several energy wavelengths. The spacecraft will track ultraviolet, visible, and infrared energy for Sun-Earth research. Scientists can apply the data to ozone recovery studies, climate analysis, and air quality forecasting.
The mission highlights Electron’s role as a responsive launch service for dedicated small satellite missions. Rocket Lab has completed more than 90 launches and has supported NASA missions for almost a decade. Its launch history includes deployments of science, technology, national security, and commercial payloads.
Rocket Lab also holds upcoming assignments for NASA’s Aspera and LOXSAT missions. Aspera will study galaxy formation, while LOXSAT will test technologies for refueling spacecraft in orbit. These missions broaden Rocket Lab’s government backlog and reinforce Electron’s position in specialized small satellite launches.
