Rocket Lab launches two small NASA satellites to monitor tropical storms

Rocket Lab launched two toaster-size satellites for NASA on Sunday, the first of four "cubesats" designed to provide hourly updates of typhoon and hurricane development in a bid to improve forecasting and provide new insights into how tropical storms evolve and intensify.

"The threat to our friends and neighbors is real and repeats every year," said Ben Kim, a program executive with NASA's Earth Science Division. The TROPICS mission, he said, "aims to improve our scientific understanding by obtaining microwave observations that allow us to see the inner structure of these storms approximately hourly.

"These observations will complement the existing weather satellites, and ultimately then can be tied to the broader understanding of the entire earth system."
