NASA and Rocket Lab launch mini satellites to revolutionize hurricane tracking.

NASA's TROPICS mission has launched its first two mini-satellites to collect data on hurricanes and typhoons. The satellites will offer hourly updates on storm growth to improve forecasting and figure out how temperature, humidity, and precipitation factor into the intensity of tropical cyclones. The $30 million mission aims to put four TROPICS satellites in space in slightly different low-Earth orbits, all circling the globe at about 30 degrees above the equator. The next two satellites could take off in about two weeks, and the mission is expected to last for a year.
