Rocket Lab Launches Japanese SAR Satellite

· By Josh Universe · 3 min read

Rocket Lab, an innovative company known for its significant contributions to the aerospace sector, achieved another milestone on May 17, 2025, by successfully launching a radar imaging satellite for the Institue for Q-shu Pioneers of Space (iQPS). This launch marks another step in the ongoing development of synthetic aperture radar (SAR) capabilities, which are vital for various applications, including environmental monitoring, disaster management, and urban planning.

Overview of the Launch

The launch took place at 4:17 a.m. Eastern Time from Pad A at Rocket Lab's Launch Complex 1 in New Zealand. The rocket used for this mission was the Electron, a small satellite launch vehicle designed to provide dedicated launch services for small payloads. After approximately 50 minutes into the flight, the Electron successfully deployed the QPS-SAR-10 satellite into a circular orbit at an altitude of 575 kilometers with an inclination of 42 degrees.

Significance of the Mission

The launch of QPS-SAR-10 is particularly significant as it represents the third deployment for iQPS by Rocket Lab and highlights the company's advantage in executing dedicated small satellite launches compared to traditional rideshare options. In contrast to more extensive launches that consolidate multiple payloads, the Electron offers customers the flexibility to secure specific orbits and define deployment schedules more effectively.

Company Statements

Shunsuke Onishi, the chief executive of iQPS, expressed his enthusiasm regarding the collaboration with Rocket Lab, stating:

"With more Electron launches ahead, we’re more committed than ever to accelerating the buildout of our satellite constellation, and we look forward to continuing this powerful partnership."

Launch Details and Future Plans

The QPS-SAR-10 satellite is the tenth in iQPS's lineup. However, early operational difficulties have hindered the performance of earlier satellites, necessitating the continuous expansion of their constellation. Notably, the inaugural satellite experienced a malfunction shortly after launch, and two others were lost during a separate Epsilon launch failure in 2022. iQPS plans to scale up its satellite network to a total of 24 satellites by 2027, with aspirations to expand this figure to an impressive 36 over time.

The contract with Rocket Lab encompasses six additional launches, four scheduled for 2025 and two for 2026. Rocket Lab announced that the next launch is already set for June 2025.

Competitive Landscape

Rocket Lab's unique offering of tailored launch services has garnered attention in the competitive landscape of satellite deployment. As Peter Beck, the chief executive of Rocket Lab, indicated:

"We have a lot of customers that will go and fly on a Transporter, and then they’ll come back and they’ll go book their whole constellation on us."

This sentiment highlights how clients increasingly view dedicated launches as crucial for meeting specific mission requirements compared to larger rideshare missions operated by competitors like SpaceX.

Financial Insights

During an earnings call on May 8, Rocket Lab disclosed a minor decrease in the average selling price (ASP) of their Electron rocket, attributing this fluctuation to the mix of contract types and customers' long-term commitments. Adam Spice, the chief financial officer, mentioned:

"We expect ASP for the calendar year 2025 to materially expand when compared to 2024."

Launch Cadence

The Electron's launch on May 17 marked the sixth mission of the year, with Rocket Lab's commitment to achieving a total of at least 20 launches this fiscal year. The company anticipates increased launch cadence particularly in the second half of 2025.

Conclusion

The successful deployment of the QPS-SAR-10 signifies Rocket Lab's ongoing journey as a leader in the small satellite launch sector, underscoring its partnerships and commitments to innovation in satellite technology. As the demand for satellite imaging solutions grows, Rocket Lab's tailored approach and future launch plans reinforce its position in the commercial space race.
