To ensure the constellation is in orbit for the 2023 storm season, Rocket Lab will launch NASA’s four TROPICS satellites from Launch Complex 1 in New Zealand across two dedicated Electron missions in May

LONG BEACH, Calif.--(BUSINESS WIRE)--Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a leading launch and space systems company, today announced it will launch NASA’s TROPICS constellation across two dedicated Electron missions lifting off from Launch Complex 1 in New Zealand next month.

“The ability to advance our understanding of tropical cyclones from space has been limited by the ability to take frequent measurements, particularly from microwave instruments that see into the storms”

The TROPICS constellation (Time-Resolved Observations of Precipitation Structure and Storm Intensity with a Constellation of Small Sats) will monitor the formation and evolution of tropical cyclones, including hurricanes, and will provide rapidly updating observations of storm intensity. This data will help scientists better understand the processes that effect these high-impact storms, ultimately leading to improved modelling and prediction. The two missions are expected to launch within approximately two weeks of each other in May 2023. The first launch, named ‘Rocket Like a Hurricane,’ is expected to launch as soon as May 1 NZST (30 April EDT) and the second mission, named ‘Coming to a Storm Near You,’ is expected to follow around May 16 NZST (May 15 EDT).

The constellation, which is part of NASA’s Earth System Science Pathfinder Program, consists of four CubeSats that require launch to a specific orbit at an altitude of 550 kilometers and inclination of about 30 degrees. All four satellites need to be deployed into their operational orbit within a 60-day period, making Electron the ideal launch vehicle as it enables dedicated launch to unique orbits on highly responsive timelines. The two missions were initially scheduled to lift-off from Launch Complex 2 at the Mid-Atlantic Regional Spaceport within NASA’s Wallops Flight Facility in Virginia but will now take place at Launch Complex 1 in New Zealand to support a Q2 launch window that will see the satellites reach orbit in time for the North American 2023 hurricane season.

“The need for improved climate and weather data from space is acute and growing. Hurricanes and tropical storms have a devastating effect on lives and livelihoods, so we’re immensely proud to be entrusted by NASA to launch the TROPICS missions which will enable scientists and researchers to accurately predict storm strength and give people time to evacuate and make plans,” said Rocket Lab founder and CEO, Peter Beck. “With the 2023 hurricane season fast approaching, time is of the essence for these missions. Because we operate three launch pads across two countries, we can constantly assess the launch manifest and adapt launch schedules and locations based on customer and mission requirements.”

“The ability to advance our understanding of tropical cyclones from space has been limited by the ability to take frequent measurements, particularly from microwave instruments that see into the storms,” says Will McCarty, Program Scientist for the TROPICS Mission. “Historically, satellites have been too large and expensive to provide observations at a time-frequency that is consistent with the timescales at which tropical cyclones can evolve. The CubeSat era has allowed for smaller, less expensive satellites. With modern small satellite design, we designed a constellation that optimizes the scientific utility of the mission in a way that we can launch in a cost-effective manner. These factors enable TROPICS to provide a new understanding of tropical cyclones by decreasing the time by which a given storm is revisited by the satellites.”

Rocket Lab was selected to launch the TROPICS missions as part of NASA’s Venture-class Acquisition of Dedicated and Rideshare (VADR) launch services contract.

A NASA constellation of four storm tracking CubeSats are getting a new launch location as they prepare to study tropical cyclones beginning in the 2023 Atlantic hurricane season. NASA’s Time-Resolved Observations of Precipitation Structure and Storm Intensity with a Constellation of SmallSats (TROPICS) will observe the atmosphere to increase our understanding of hurricanes, typhoons, and other intense weather.

Rocket Lab has announced the mission now will be sent into orbit on two Electron rockets – each carrying two TROPICS CubeSats – from Launch Complex 1 in Mahia, New Zealand in May to maintain the target launch window in time for this year’s hurricane season.

Each launch, traveling to separate orbital planes, will place a pair of the small satellites in orbit to increase the frequency in which tropical cyclones are measured from space. The TROPICS constellation enables researchers to monitor the evolution of tropical cyclones with a frequency of about once per hour as compared to currently only once every 6 hours. Each TROPICS satellite is an identical 3U (1U, or unit = 10cm x 10cm x 10cm) CubeSat that is about the size of a loaf of bread and weighs about 12 pounds.

The TROPICS team is led by Dr. William Blackwell at Massachusetts Institute of Technology’s Lincoln Laboratory in Lexington, Massachusetts, and includes researchers from NASA, the National Oceanic and Atmospheric Administration (NOAA), and several universities and commercial partners. NASA awarded the launch services to Rocket Lab in November 2022, as part of the agency’s Venture-class Acquisition of Dedicated and Rideshare (VADR) launch services contract.

NASA, Rocket Lab Update Launch Coverage for Tropical Cyclones Mission

After the previous launch target date changed due to weather conditions in New Zealand, NASA and Rocket Lab are now targeting 9 p.m. EDT Sunday, May 7, (1 p.m. Monday, May 8, New Zealand Standard Time), to launch two storm tracking CubeSats into orbit. 

The agency’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission has a two-hour launch window from Launch Complex 1 Pad B in Māhia, New Zealand.

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.

A second launch from Rocket Lab will carry two additional CubeSats, with exact launch times contingent on the date and time of the first launch. TROPICS is a constellation of four identical CubeSats designed to observe tropical cyclones from low Earth orbit, making observations more frequently than current weather tracking satellites. Gathering data more frequently can help scientists improve weather forecasting models.

TROPICS will study tropical cyclones as part of NASA’s Earth Venture Class missions, which select targeted science missions to fill gaps in our overarching understanding of the entire Earth system.

Full coverage of this mission is as follows (all times Eastern):

 

Sunday, May 7

 

Approximately 8:40 p.m. – Live launch coverage begins

 

9 p.m. – Launch window opens

 

NASA website launch coverage

Follow countdown coverage on NASA’s launch blog for live updates beginning no earlier than 8 p.m. as the countdown milestones occur. On-demand streaming video and photos of the launch will be available shortly after liftoff on Rocket Lab’s website and Flickr. Imagery also is available on the NASA website.
