TROPICS Launch Now Targeting May 25

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. TROPICS will provide data on temperature, precipitation, water vapor, and clouds by measuring microwave frequencies, providing insight into storm formation and intensification. The data will help scientists better understand the processes that effect these high-impact storms, ultimately leading to improved modeling and prediction.

Rocket Lab will provide live coverage beginning approximately 20 minutes before launch. Coverage will air on NASA Television, the NASA app, the agency’s website, and Rocket Lab’s website. Coverage will begin around 11:40 p.m. EDT on May 24.

Weather Delays TROPICS Launch

NASA and Rocket Lab are now targeting no earlier than 1:00 a.m. EDT Tuesday, May 23, (5:00 p.m. NZST) for the launch of a pair of storm tracking CubeSats due to unfavorable weather conditions. TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) remains healthy and ready for launch on a Rocket Lab Electron rocket from Launch Complex 1 in Mahia, New Zealand. Originally, Rocket Lab was targeting no earlier than 1:30 a.m. EDT (5:30 p.m. NZST) Monday, May 22, for the launch.

Rocket Lab will continue to assess the weather as it evolves.

TROPICS Launch Date Set

NASA and Rocket Lab are targeting no earlier than 1:30 a.m. EDT (5:30 p.m. NZST) Monday, May 22, for the launch of the agency’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission, on an Electron rocket from Launch Complex 1 in Māhia, New Zealand.

The launch will place a pair of CubeSats in low Earth orbit, and they will join another pair of TROPICS satellites that made it to orbit last week after launching on an Electron rocket from New Zealand. 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. They they will join the TROPICS Pathfinder satellite, in orbit since its launch in June of 2021.

Signal Acquired!

Team members successfully sent commands to the first CubeSat at 1:48 a.m. EDT, May 8. Subsequently, they established communications with the second CubeSat at 6:31 a.m. EDT. Read the NASA release here.

Working Toward Signal Acquisition

Two TROPICS CubeSats successfully deployed from a Rocket Lab Electron rocket after launch.

The team is working toward signal acquisition from the pair of TROPICS CubeSats. NASA will continue to assess data from periodic pass opportunities. It is not unexpected for CubeSats to take some time to establish communications. We will provide confirmation when signal is acquired.

The second pair of TROPICS CubeSats is planned to launch aboard another Rocket Lab Electron rocket, named Coming To A Storm Near You, in about two weeks from Launch Complex 1 at Māhia, New Zealand.

TROPICS CubeSats Expected to Have Deployed

NASA’s TROPICS CubeSats are expected to have deployed from the Rocket Lab’s Electron kick stage. The two CubeSats will reach low-Earth orbit to begin their mission.

Each of the CubeSats was designed to last approximately two years, but analysis, lifetime testing of key parts, and on-orbit experiences with similar hardware could help the satellites surpass their design lifetime.

Electron’s Second Stage Separates

The second stage of Rocket Lab’s Electron has cut off and separated from the payload kick stage. Soon, the kick stage engine will ignite and burn for about three minutes before it cuts off.

Electron Performs Battery Hot Swap

The Electron rocket has successfully completed the battery hot swap, switching power between batteries. The next milestone is second stage separation in about three minutes.

Liftoff For Rocket Like a Hurricane!

Rocket Lab’s Electron rocket lifts off from Launch Complex 1 at Māhia, New Zealand at 9:00 p.m., carrying two TROPICS CubeSats for NASA.

A series of milestones will occur within several minutes after launch. The rocket will reach MaxQ, which is the speed at which the vehicle reaches its maximum dynamic pressure. Electron’s first stage main engines will cut off, followed by separation from the second stage. The payload fairing surrounding TROPICS will jettison.
