NASA's PACE satellite is scheduled for launch on Feb. 6, aimed at studying microscopic particles in the atmosphere and water.

The mission, with a budget of $964 million, includes equipment like an optical spectrometer to capture high-resolution images.

PACE will enhance knowledge of phytoplankton roles in aquatic ecosystems and aerosol impacts on sunlight scattering and absorption.

The mission's data will be instrumental in addressing complex climate questions and will be accessible to the scientific community.

The satellite will also analyze sea salt, smoke, pollutants, and dust interactions, crucial for climate modeling and ocean-atmosphere studies.
