A NASA-led science team spent six weeks in January and February studying Hawaii's volcanos and coral reefs using the agency's ER-2 aircraft. The mission, called Hyperspectral InfraRed Imager (HyspIRI), focused on observing coral reef health and volcano emissions and eruptions. Flying at 65,000 feet (19,800 meters), above 95 percent of Earth’s atmosphere, the ER-2 can closely replicate the data a future satellite could collect. Data from this mission will help in developing a NASA satellite to st
