SpaceX Launched NASA’s PACE satellite to Study Earth’s Oceans, Air & Climate

Current Context: NASA’s Plankton, Aerosol, Climate, ocean Ecosystem (PACE) satellite was launched aboard a SpaceX Falcon 9 rocket at 1:33 a.m. EST, on February 8, 2024, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

• The PACE mission will study microscopic life in the oceans and microscopic particles in the atmosphere to investigate key mysteries of our planet’s interconnected systems.
• The satellite’s hyperspectral ocean color instrument will allow researchers to measure oceans and other water bodies across a spectrum of ultraviolet, visible, and near-infrared light.
• This will enable scientists to track the distribution of phytoplankton and – for the first time from space – identify which communities of these organisms are present on daily, global scales.
• The spacecraft also carries two polarimeter instruments, Hyper-Angular Rainbow Polarimeter #2 and Spectro-polarimeter for Planetary Exploration.
• These will detect how sunlight interacts with particles in the atmosphere, giving researchers new information on atmospheric aerosols and cloud properties, as well as air quality at local, regional, and global scales.
