Welcome to Launch Day for NASA’s TROPICS

It’s launch day for NASA’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission! A pair of small satellites wait atop a Rocket Lab Electron rocket for liftoff from Launch Complex 1 in Māhia, New Zealand. This launch, named Rocket Like A Hurricane, is the first of two planned launches, each sending a pair of shoebox-sized satellites, called CubeSats, to low-Earth orbit, where they will more frequently collect data to help increase understanding of these deadly storms and improve tropical cyclone forecasts complementing other NASA and partner satellites, including the Global Precipitation Measurement (GPM) Mission and the Suomi National Polar-orbiting Partnership (Suomi NPP).

A two-hour launch window opens at 9 p.m. EDT Sunday, May 7, (1 p.m. Monday, May 8, New Zealand Standard Time).

Together the two launches will attempt to place four CubeSats in two equally spaced orbital planes, so they are spread over the globe for optimal coverage. The CubeSats will study the formation and development of tropical cyclones, known as hurricanes in the Atlantic and typhoons in the West Pacific. The full TROPICS constellation will make observations more often than what is possible with current weather satellites. When they reach orbit, these TROPICS satellites will join the TROPICS Pathfinder satellite which is already in orbit.

All four TROPICS satellites need to be deployed into their operational orbit within a 60-day period. The TROPICS satellites will cover the part of the Earth where tropical cyclones form and will work in concert to improve observations of the powerful storms. The distribution of the satellites means that one should pass over any spot in an area stretching from the Mid-Atlantic region of the United States to the southern coast of Australia about once an hour. TROPICS will provide data on temperature, precipitation, water vapor, and clouds by measuring microwave frequencies, providing insight into storm formation and intensification. This new data, coupled with information collected from other weather satellites, will increase understanding of tropical cyclones, and should improve forecasting models.
