Weather is 85% favorable for the upcoming launch of Rocket Lab’s Electron rocket carrying the final pair of NASA’s TROPICS CubeSats. The team is expecting minimal clouds and light winds over Launch Complex-1 in in Māhia, New Zealand throughout the countdown and through lift-off.
Weather officials from Rocket Lab predict an 80 percent chance of favorable weather conditions for today’s launch window.
The primary weather concern for the launch window is ground winds.
TROPICS CubeSats use different wavelengths to see different features of storms in their surrounding environment, and they make more frequent passes of tropical cyclones than current weather satellites. The data provided will help scientists better understand the processes that affect these high-impact storms, ultimately leading to improved modeling and prediction.

After a weather delay, a pair of small weather tracking satellites are ready to launch to space aboard a Rocket Lab Electron rocket from Launch Complex 1 in Māhia, New Zealand a few hours from now. NASA’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission is sending a pair of shoebox-sized satellites, called CubeSats, to low Earth orbit to collect tropical storm data more frequently than other weather satellites.
TROPICS will 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 70-minute launch window opens at no earlier than 11:30 p.m. EDT Thursday, May 25, (3:30 p.m. NZST Friday, May 26th).
Once deployed, the two CubeSats from today’s launch will join the TROPICS CubeSats already in orbit in two equally spaced orbital planes, which will distribute them for optimal coverage over the Earth. The orbiting TROPICS constellation of satellites will study the formation and development of tropical cyclones, known as hurricanes in the Atlantic and typhoons in the West Pacific, making observations of temperature, precipitation, water vapor, and cloud ice more often than what is possible with current weather satellites. With the four TROPICS satellites in orbit, they will join the TROPICS Pathfinder satellite, in orbit since its launch in June of 2021.
This launch, named Coming To A Storm Near You, marks the second of two TROPICS launches for NASA, following Rocket Lab’s first launch from this same launch pad at 9 p.m. EDT Sunday, May 7, (1 p.m. Monday, May 8, New Zealand Standard Time).
Rocket Lab will provide live coverage beginning approximately 20 minutes before launch on May 25. Coverage will air on NASA Television, the NASA app, the agency’s website, and Rocket Lab’s website.

NASA and Rocket Lab are now targeting no earlier than 11:30 p.m. EDT Thursday, May 25, (3:30 p.m. NZST Friday, May 26th) for the launch of the agency’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission, from Launch Complex 1 in Mahia, New Zealand.
Due to strong upper-level winds present throughout the count and expected to remain at the launch’s targeted lift-off time, Rocket Lab’s launch director called a scrub before fueling the Electron rocket.
This final TROPICS launch will place a pair of CubeSats in low Earth orbit to join another pair of TROPICS satellites launched earlier this month. Together the four satellites will orbit in two equally spaced orbital planes, which will distribute them for optimal coverage over the tropics. The orbiting TROPICS constellation of satellites will study the formation and development of tropical cyclones, known as hurricanes in the Atlantic and typhoons in the West Pacific, making observations of temperature, precipitation, water vapor, and cloud ice more often than what is possible with current weather satellites.

Launch day is here for NASA’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission! Atop a Rocket Lab Electron rocket, a pair of small satellites await liftoff from Launch Complex 1 in Māhia, New Zealand, to join a pair of recently deployed TROPICS satellites that launched just over two weeks ago.
This mission, named Coming To A Storm Near You, marks the second of two Rocket Lab TROPICS launches for NASA, following the company’s first launch from this very spot at 9 p.m. EDT Sunday, May 7, (1 p.m. Monday, May 8, New Zealand Standard Time). Like the previous launch, today’s launch is sending a pair of shoebox-sized satellites, called CubeSats, to low Earth orbit to collect tropical storm data more frequently than other weather satellites. TROPICS will 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 70-minute launch window opens at no earlier than 4 p.m. New Zealand Standard Time (12 a.m. EDT).
Once deployed, the two CubeSats from today’s launch will join the TROPICS CubeSats already in orbit in two equally spaced orbital planes, which will distribute them for optimal coverage over the Earth. The orbiting TROPICS constellation of satellites will study the formation and development of tropical cyclones, known as hurricanes in the Atlantic and typhoons in the West Pacific, making observations of temperature, precipitation, water vapor, and cloud ice more often than what is possible with current weather satellites. With the four TROPICS satellites in orbit, they will join the TROPICS Pathfinder satellite, in orbit since its launch in June of 2021.
The short turnaround between launches is predicated on the need to have all four deployed into their operational orbit within a 60-day period. Since the TROPICS satellites will cover the part of the Earth where tropical cyclones form, 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. Working in concert to improve observations of the powerful storms, 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.

NASA and Rocket Lab are now targeting no earlier than 12 a.m. EDT Thursday, May 25, (4 p.m. NZST) for the final launch of the agency’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission due to unfavorable weather conditions. Rocket Lab will continue to assess the weather, and provide updates.
The pair of spacecraft remain healthy and ready for launch on a Rocket Lab Electron rocket from Launch Complex 1 in Māhia, New Zealand.
This launch is the second of two planned launches, each sending a pair of shoebox-sized satellites to low Earth orbit to make more frequent observations of tropical cyclones, which includes hurricanes and typhoons.
