NASA launches four Earth science missions in 2022 – Everything You Need to Know

  • NASA has planned four geoscientific missions in 2022.
  • These missions will provide data to help scientists better understand climatic and weather conditions.
  • NASA’s Earth observation satellites will be used for these missions.

NASA plans to launch four Earth science missions in 2022 that will help scientists learn more about climatic conditions and systems.
NASAs Earth observation satellites will assist in these scientific missions.

The four
NASA science missions includes TROPICS, EMIT, NOAA’s JPSS-2 and SWOT. Each mission is designed to observe different climatic systems on Earth. TROPICS, for example, will use six small satellites to study and provide rapid measurements of tropical cyclones. EMIT will track the origin and composition of mineral dust using an International Space Station (ISS) imaging spectrometer. NOAA’s JPSS-2 will help scientists predict extreme weather conditions, and SWOT will investigate surface water and their role in climate change.


For this mission, NASA will use six satellite-sized satellites to observe tropical cyclones. These satellites will travel in pairs and in three different orbits, providing microwave observations of a “storm’s precipitation, temperature, and humidity as fast as every 50 minutes.” These data are expected to help scientists better understand what is causing the catastrophic tropical cyclones and also help with weather forecasts.


Through the Earth Surface Mineral Dust Source Investigation (EMIT) mission, NASA will use satellites to learn where dust originates and how it affects the planet. NASA plans to use an image spectrometer that measures visible and infrared light reflected from surfaces below. This mission will take place in one year and it will be installed on the ISS.


The National Oceanic and Atmospheric Administration and NASA’s Joint Polar Satellite System satellites, currently orbiting the Earth, provide data to help predict extreme storms. These satellites also provide information on floods, wildfires, volcanoes, smog, dust storms and sea ice. NASA now plans to launch the JPSS-2 satellite in 2022, which will further help scientists predict extreme weather conditions. Three more such satellites are planned in the future.


NASA’s Surface Water and Ocean Topography mission will collect data from Earth’s surface water bodies such as the oceans, lakes and rivers, and how much climate change is affecting these freshwater areas. It will also provide data on the ocean’s ability to absorb excess heat and greenhouse gases such as carbon dioxide.
