Electron has been selected by @nasa for three launches in 2027 to deploy its PolSIR and TSIS-2 Sun and Earth sciences missions. We've been delivering reliability, precise orbital accuracy, and on-demand launch for NASA missions for almost a decade - and we're ready to deliver that once again for PolSIR and TSIS-2 from Launch Complex 1 early next year.

For TSIS-2, Electron will launch a single satellite to measure the Sun’s brightness at the top of Earth’s atmosphere. The data collected can be used by scientists to predict Earth’s ozone layer recovery or provide air quality forecasts. Launching NET early 2027.

For PolSIR, Electron will deploy a pair of satellites across two launches to LEO to study ice clouds at high altitudes in the tropics and sub-tropics: how they form, why they change throughout the day, and how much ice they contain. Launching NET June 2027.

Satellite builds can take years. For our Pioneer spacecraft for VICTUS HAZE, going from contract to launch ready took ~18 months πŸ’ͺπŸ›°οΈ An incredibly aggressive timeline for an important mission for the @USSpaceForce and @USSF_SSC, and the team delivered.

Where others promise responsiveness, we deliver it with Electron - repeatedly. With reliable rockets, a steady production line, launch sites we control, and an experienced team that moves quickly, we deliver every piece that matters for responding fast to the nation's most important missions.

Our TacRS launch went to orbit June 19 as part of our multi-launch, multi-vehicle VICTUS HAZE mission. A demo of #USSF's capability to rapidly acquire, launch & operate space vehicles in response to urgent on-orbit threats. Shout out to mission partners! ssc.spaceforce.mil/Newsroom/…
