Rocket Lab Launches Japanese Radar Satellite on ‘Eight Days a Week’ Mission

The mission, dubbed “Eight Days a Week,” lifted off aboard a Electron rocket from Rocket Lab’s launch complex in New Zealand at 2:10 p.m. EDT (1810 GMT; 7:10 a.m. local time on March 21). The rocket carried one of Synspective’s Strix satellites into orbit, continuing the steady expansion of the company’s radar imaging network.

The mission name reflects the deepening collaboration between the two firms—this was the eighth launch Rocket Lab has conducted for Synspective to date.

Synspective, headquartered in Tokyo, is developing a constellation of synthetic aperture radar (SAR) satellites designed to deliver high-resolution imaging regardless of weather or lighting conditions. The data collected by the Strix satellites is intended to support a range of applications, including urban planning, construction monitoring, infrastructure management, and disaster response.

Rocket Lab has served as the exclusive launch provider for the Strix constellation since its first satellite deployment in 2020. The partnership is set to continue well into the future, with Synspective booking approximately 20 Electron launches to complete its planned constellation by 2029.

Friday’s mission also marked the 77th launch of the Electron rocket, a 59-foot-tall (18-meter) small-lift vehicle that first flew in May 2017 and has since become a key player in the small satellite launch market.

Beyond orbital missions, Rocket Lab has expanded its capabilities with HASTE, a suborbital variant of Electron tailored for hypersonic technology testing. The company has conducted seven such missions to date, further diversifying its launch services portfolio.

Approximately 50 minutes after liftoff, the Strix satellite was successfully deployed into low Earth orbit, completing another precise delivery for Rocket Lab and bringing Synspective one step closer to realizing its full radar imaging constellation.
