Rocket Lab Prepares for Second TROPICS Launch to Deploy Storm Monitoring Constellation for NASA

The ‘Coming to a Storm Near You’ launch is scheduled to lift off from Rocket Lab Launch Complex 1 in New Zealand as early as May 25. It will be the second Electron launch in two weeks to deploy the TROPICS storm monitoring constellation for NASA

MAHIA, New Zealand–(BUSINESS WIRE)–$RKLB–Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a leading launch and space systems company, is preparing for the second of two dedicated Electron launches to deploy a constellation of storm monitoring satellites for NASA. This mission, named Coming To A Storm Near You, is scheduled for lift-off no earlier than 16:00 NZST on May 25^th from Launch Complex 1 on New Zealand’s Mahia Peninsula.

Launch Window Opens:

NZST | 16:00, May 25

UTC | 04:00, May 25

EDT | 00:00, May 25

PDT| 21:00, May 24

Coming To A Storm Near You marks Rocket Lab’s second of two TROPICS launches for NASA, following the first launch on May 8^th NZST. Like the previous launch, Coming To A Storm Near You will send a pair of shoebox-sized satellites to low Earth orbit to collect tropical storm data more frequently than other weather satellites. The TROPICS constellation (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) will help increase understanding of deadly storms and improve tropical cyclone forecasts, complementing other NASA and partner satellites. The TROPICS CubeSats require launch to a specific orbit at an altitude of 550 kilometers and inclination of about 30 degrees and all four satellites need to be deployed into their operational orbit within a 60-day period ahead of the 2023 North American storm season which begins in June.

“The TROPICS constellation has the potential to save lives and improve our knowledge of deadly storms, so we’re immensely proud to be part of making it possible,” said Rocket Lab founder and CEO, Peter Beck. “With one pair of TROPICS satellites now safely in orbit, we’re pleased to be back on the pad just two weeks later ready for the next launch. Regular and reliable dedicated small sat launch is what we developed Electron and our launch sites for, so it’s a great feeling to be delivering on that for NASA.”

Coming To A Storm Near You will be Rocket Lab’s fifth Electron mission for 2023 and the Company’s 37^th launch overall since Rocket Lab’s first Electron launch in 2017. The TROPICS launches follow on from previous successful Electron missions for NASA, including the ELaNa-19 mission and CAPSTONE mission to the Moon.

These forward-looking statements are based on Rocket Lab’s current expectations and beliefs concerning future developments and their potential effects. These forward-looking statements involve a number of risks, uncertainties (many of which are beyond Rocket Lab’s control), or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. Many factors could cause actual future events to differ materially from the forward-looking statements in this release, including risks related to our dependence on a limited number of customers; the harsh and unpredictable environment of space in which our products operate which could adversely affect our launch vehicle and spacecraft; increased congestion from the proliferation of low Earth orbit constellations which could materially increase the risk of potential collision with space debris or another spacecraft and limit or impair our launch flexibility and/or access to our own orbital slots; increased competition in our industry due in part to rapid technological development and decreasing costs; technological change in our industry which we may not be able to keep up with or which may render our services uncompetitive; average selling price trends; failure of our launch vehicles, spacecraft and components to operate as intended either due to our error in design in production or through no fault of our own; launch schedule disruptions; supply chain disruptions, product delays or failures; design and engineering flaws; launch failures; natural disasters and epidemics or pandemics; changes in governmental regulations including with respect to trade and export restrictions, or in the status of our regulatory approvals or applications; or other events that force us to cancel or reschedule launches, including customer contractual rescheduling and termination rights; risks that acquisitions do not achieve the anticipated benefits and results; and the other risks detailed from time to time in Rocket Lab’s filings with the Securities and Exchange Commission (the “SEC”), including under the heading “Risk Factors” in Rocket Lab’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the SEC on March 7, 2023, and elsewhere.
