The SpaceX Falcon 9 rocket successfully launched NASA’s newest Earth-observation satellite, the PACE (Plankton, Aerosol, Cloud, Ocean Ecosystem) mission.
The rocket lifted off from Florida’s Cape Canaveral Space Force Station on Thursday, February 8, at 1:33 a.m. EST. Approximately 13 minutes after launch, the spacecraft successfully separated from the launch vehicle.
The PACE mission has a big goal: to monitor the health of our planet in the face of climate change. PACE will collect extensive data, ranging from high-altitude cloud cover to the depths of the ocean.
Throughout its three-year operating life, the satellite will study the interactions of the ocean, clouds, and aerosols to enhance our understanding of these dynamic processes.
This 10-foot-tall satellite will orbit Earth at a height of 676.5 kilometers with an inclination of 98°. And will complete on Earth orbit in every 98.3 minutes. For comparison, the International Space Station orbits at a height of approximately 402 kilometers.
Monitoring Earth’s ocean and atmosphere
According to NASA, the PACE mission will provide important insights into Earth’s ocean and atmosphere. It will accomplish this by measuring key factors such as cloud coverage, airborne particles and pollutants, and tiny marine life.
Among the set science goals, the satellite will gather information on the mechanisms involved in oceanic carbon dioxide exchange. Additionally, it will unveil the potential role of aerosols in stimulating phytoplankton growth at the ocean’s surface.
Aerosols are small airborne particles that absorb and reflect sunlight, while phytoplankton are microscopic sea algae. These measurements will also give information on the effects of climate change.
For example, PACE will investigate the effects of climate change on the growth of marine phytoplankton. Furthermore, it will help us understand how airborne particles like dust and smoke impact cloud formation and contribute to the planet’s warming and cooling processes.
