NASA has propelled a new frontier in climate research with the successful launch of the Plankton, Aerosol, Climate, ocean Ecosystem (PACE) satellite. 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, PACE promises to revolutionize our understanding of Earth’s interconnected systems.
The PACE mission, a testament to international collaboration and scientific innovation, aims to unravel the mysteries of our planet’s oceans and atmosphere. From its orbit hundreds of miles above Earth, PACE will delve into the microscopic world, studying both microscopic life in the oceans and minuscule particles in the atmosphere.
“This successful launch marks a significant milestone in our quest to understand the complexities of Earth’s climate,” remarked NASA Administrator Bill Nelson. “PACE will provide unprecedented insights into the factors driving global warming, supporting the Biden-Harris Administration’s climate agenda and addressing urgent questions about our changing climate.”
At the heart of the PACE mission is its cutting-edge instrumentation. Equipped with a hyperspectral ocean color instrument, PACE will capture data across various wavelengths of light, allowing researchers to monitor oceans and water bodies with unparalleled precision. This technology will enable scientists to track the distribution of phytoplankton, crucial organisms that serve as indicators of marine health and biodiversity.
Furthermore, PACE carries two polarimeter instruments, which will illuminate the interactions between sunlight and atmospheric particles. By deciphering these interactions, researchers will gain new insights into atmospheric aerosols, cloud properties, and air quality on local, regional, and global scales.
“The launch of PACE heralds a new era of ocean science,” stated Karen St. Germain, director of the Earth Science Division at NASA Headquarters. “By combining PACE data with insights from other missions, such as the Surface Water and Ocean Topography mission, we are poised to unlock a wealth of knowledge about our planet’s dynamic systems.”
The significance of PACE extends beyond scientific inquiry. With Earth’s oceans undergoing profound changes due to climate change, PACE will play a pivotal role in understanding the impact on marine ecosystems. Phytoplankton, in particular, serve as vital agents in the global carbon cycle, influencing climate patterns and supporting ecosystems upon which humanity relies.
“After two decades of anticipation, witnessing the launch of PACE is truly exhilarating,” expressed Jeremy Werdell, PACE project scientist at NASA’s Goddard Space Flight Center. “The opportunities that PACE presents are boundless, promising a journey of discovery that will reshape our understanding of Earth’s delicate balance.”
Managed by NASA Goddard, the PACE mission represents a collaborative effort involving international partners and scientific communities. With its state-of-the-art technology and unwavering dedication, PACE is poised to deliver transformative insights into our planet’s climate and pave the way for informed decision-making in the face of global challenges.
