NASA and SpaceX launched the PACE satellite from Florida to study phytoplankton, aerosols, and sunlight's atmospheric impact.

The launch marked the first U.S. polar or sun-synchronous orbit mission from Florida since 1960, following a sonic boom from the rocket's landing.

Initially at risk of cancellation, the PACE mission proceeded with advocacy support for Earth's climate research.

The Ocean Color Instrument aboard PACE will analyze sunlight interaction with the atmosphere and collect phytoplankton data.

After a two-month commissioning, PACE will commence scientific observations to enhance understanding of oceans and climate change.
