NASA has delayed two airborne missions that study Earth’s climate and the effects of climate change, and one tasked with understanding extreme weather, due to concerns about the COVID-19 pandemic.

“Due to the current uncertainty about the coronavirus situation in the United States and its potential impact on travel during the next few weeks, three NASA Earth Science airborne science campaigns slated to deploy across the country this spring have rescheduled their field activity until later in the year,” said Jim Bridenstine, NASA’s administrator, in a recent statement.
