NASA has 4 new Earth Science Missions Launching in 2022
Outer space is a great place to go if you want to study the Earth. Although outward-looking spacecraft like Hubble and the highly anticipated James Webb Space Telescope garner most of the attention from the public – understandably, given their spectacular imagery of distant astronomical phenomena – the large majority of satellite infrastructure in orbit is actually focused back on our home planet. The unparalleled view of the planet from space offers unique advantages to scientists hoping to measure changes and patterns here on Earth that just aren’t possible from the ground. In 2022, NASA will launch four new Earth science missions, each offering something unique, and adding a new way to understand, and protect, our home.
