NASA's PACE Mission Successfully Launched to Study Ocean Health, Air Quality, and Climate Impact from Space

NASA has finally launched its Plankton, Aerosol, Cloud, and Ocean Ecosystem (PACE) mission after a nine-year wait.

This groundbreaking satellite aims to observe microscopic life forms and atmospheric particles, potentially transforming our understanding of global warming and the vulnerabilities of ocean ecosystems.

PACE Mission Achieves Milestone Launch From Cape Canaveral

Launching successfully at 1:33 a.m. ET Thursday, February 8, from Cape Canaveral Space Force Station in Florida, the NASA PACE mission marked a significant milestone. Aboard a SpaceX Falcon 9 rocket, the mission saw the booster landing back on Earth about 10 minutes post-launch, and within just over half an hour, the spacecraft's solar arrays were confirmed to have deployed, ensuring it received power.

Originally slated for Tuesday, the launch encountered two delays due to unfavorable conditions of high winds and cumulus clouds. However, Thursday's launch proceeded smoothly with weather conditions more than 95% favorable.

NASA Administrator Bill Nelson extended congratulations to the PACE team for the successful launch, emphasizing the mission's role in advancing knowledge about particles' impact on the atmosphere and oceans. This understanding is crucial for addressing global warming and aligns with the climate agenda of the Biden-Harris Administration.

PACE Mission: Unveiling Earth's 'Invisible Universe' from Above

From an elevated vantage point, the PACE mission is set to explore the "invisible universe" of Earth, such as microscopic aquatic life and airborne particles. Using a hyperspectral ocean color instrument, researchers can gauge oceans and waterbodies across various light spectra, enabling the unprecedented monitoring of phytoplankton distribution on a global scale.

This innovative approach allows scientists and coastal managers to anticipate fishery health, monitor harmful algal blooms, and discern alterations in the marine environment.

Equipped with polarimeter instruments, including Hyper-Angular Rainbow Polarimeter #2 and Spectro-polarimeter for Planetary Exploration, the spacecraft explores sunlight's interaction with atmospheric particles, providing insights into aerosols, cloud properties, and air quality at various scales.

This integration enhances PACE's ability to scrutinize the complex interplay between the ocean and atmosphere, contributing to a comprehensive understanding of how a changing climate impacts these dynamics.

Karen St. Germain, NASA's Earth Science Division director, anticipates that PACE's observations will significantly improve understanding of the ocean's role in the climate cycle. The collaboration of PACE data with the Surface Water and Ocean Topography mission marks a transformative era in ocean science.

As an open-source mission, PACE aims to accelerate understanding of the Earth system and provide practical applications for challenges faced by coastal communities and industries.

Marjorie Haskell, PACE's program executive at NASA Headquarters, commends the team's resilience, in overcoming obstacles, including the global pandemic, to bring the observatory into reality. PACE is set to play a vital role in studying climate change's impact on phytoplankton, crucial for the global carbon cycle.

These diminutive organisms wield influence over larger ecosystems, contributing to food security, recreation, and the economy. Jeremy Werdell, the PACE project scientist, expresses enthusiasm for the mission's potential discoveries after two decades of contemplation, marking a significant milestone in space exploration.
