NASA has launched the final pair of a satellite quartet designed to track tropical cyclones hour by hour, in a project that could improve weather predictions on devastating storms.
The storm trackers, sent into orbit on a rocket built by US company Rocket Lab and launched from New Zealand’s Mahia Peninsula early Friday, completed the TROPICS constellation of shoebox-sized satellites.
They can fly over hurricanes (or typhoons in the Pacific) every hour, compared to every six hours with current satellites.
“As a lifelong Floridian, I know firsthand how critical it is for millions of Americans to have timely and accurate forecasts for hurricanes,” NASA administrator Bill Nelson said in a statement.
“More intense rainfall and increased coastal flooding are devastating livelihoods and taking lives, demonstrating the importance of NASA’s cutting-edge science to help answer questions that nobody else can.”
The first pair of satellites were launched successfully earlier this month.
The information gathered on rainfall, temperature and humidity could help scientists determine where a hurricane will make landfall and how intense it will be, helping people living in coastal areas be better prepared for possible evacuations.
In the long term, a better understanding of the formation and evolution of these storms could help improve climate models.
The constellation was originally intended to have six satellites, not four, but the first two were lost when a US Astra rocket malfunctioned shortly after lift-off last year.
Hurricanes, or typhoons, are becoming more powerful as the ocean surface warms, scientists say.
