MAHIA, New Zealand — Rocket Lab's Electron rocket has flown its 99th mission, carrying a Japanese radar-imaging satellite into orbit on Tuesday, November 3, 2026, and leaving the small launcher one flight away from a century of launches. The mission, named "The Sea God Surveys," lifted off from Rocket Lab Launch Complex 1 on New Zealand's Mahia Peninsula at 5:41 a.m. local time and deployed the WADATSUMI-II synthetic aperture radar (SAR) satellite into a 575-kilometre low Earth orbit for the Institute for Q-shu Pioneers of Space (iQPS), a Japanese Earth-observation company.

What Happened
According to Rocket Lab, the Electron rocket launched from Launch Complex 1 in Mahia, New Zealand, at 5:41 a.m. NZDT on November 3, 2026, carrying the WADATSUMI-II satellite for iQPS. The satellite was delivered to a 575-kilometre low Earth orbit on an inclination tailored specifically to optimise iQPS's revisit rates over the Asia-Pacific region, Rocket Lab said in its mission announcement. Launch coverage reported that the payload was deployed about 56 minutes after liftoff.
Rocket Lab described the flight as the 99th flight of Electron and its 20th mission of 2026, and said Electron remains the most frequently launched commercial small rocket in the world. The company also said the mission was its tenth consecutive launch for iQPS with a 100 percent mission success record, deepening a multi-launch partnership under which eight more dedicated Electron launches are booked to complete iQPS's radar constellation by 2030.
The mission name, "The Sea God Surveys," echoes the satellite's name: WADATSUMI is the name of a Japanese sea god, a fitting title for a spacecraft whose radar eyes will watch over oceans, coastlines and land alike. Unlike a traditional optical camera, a synthetic aperture radar satellite sends out radio waves and reads the reflections, allowing it to produce images through cloud cover and in darkness — conditions that frequently block conventional Earth-observation satellites over the cloudy Asia-Pacific region.

Background
iQPS, short for the Institute for Q-shu Pioneers of Space, is building a constellation of radar satellites designed to deliver high-resolution, near-real-time imagery of Earth. The company plans a constellation of 36 SAR satellites in low Earth orbit, according to launch coverage of the mission, and Rocket Lab has become its primary launch provider, flying dedicated Electron missions that let iQPS place each satellite into precisely the orbit its constellation design requires.
Electron itself is a two-stage small rocket powered by Rutherford engines, which use electric pumps to feed propellant to the engines — a design choice that helped make Electron one of the first commercially successful small launch vehicles. Since its first orbital flight in 2018, Electron has grown from an experimental small launcher into a workhorse for constellation deployment, carrying payloads for commercial operators, government agencies and scientific missions from both New Zealand and the United States.
The radar constellation business has expanded rapidly in recent years because SAR imagery fills gaps that optical satellites cannot. Disaster-response teams use radar images to map flooding beneath cloud cover after storms; maritime watchers track ships at night; and insurers, farmers and governments use repeated radar passes to monitor ground movement, soil moisture and infrastructure change. By choosing an orbit inclination tuned for Asia-Pacific revisit rates, iQPS aims to return to the same areas more frequently, shortening the wait between images of fast-changing events such as floods and typhoons.
Rocket Lab, listed on Nasdaq as RKLB, describes itself as an end-to-end space company delivering rockets, satellites and spacecraft components for commercial, government and defence missions. Beyond Electron, it operates the HASTE suborbital test vehicle and is developing Neutron, a larger reusable medium-lift rocket intended to carry heavier payloads and, eventually, compete for bigger constellation and government contracts.

Why It Matters
The 99th Electron flight matters for three reasons. First, it puts Rocket Lab on the verge of a milestone few commercial rockets have reached: 100 flights of the same vehicle family. In an industry where many small launchers have failed after a handful of flights, Electron's longevity has made it a default choice for operators that need a satellite delivered to an exact orbit on a schedule they control, rather than ridesharing on a larger rocket and accepting whatever orbit the primary payload dictates.
Second, the mission strengthens the Asia-Pacific's independent Earth-observation capacity. Japan, through iQPS, is building a radar constellation that can watch its own region in near-real time, day and night and through the typhoon-season cloud that blankets much of East and Southeast Asia. For disaster-prone countries across the Pacific Rim, faster radar revisit times can mean earlier flood maps, quicker damage assessments and better information for rescue teams in the first hours after a catastrophe.
Third, the flight illustrates how the commercial launch market has matured. A decade ago, a dedicated launch for a single small satellite was an expensive rarity; today, Rocket Lab flies 20 missions in a year and books eight more for a single customer years in advance. That cadence, and the repeat business behind it, is what turns a rocket from an experiment into infrastructure — and it is why the company's 100th Electron flight, when it comes, will be watched as a marker of how far the small-launch industry has come.
What Happens Next
WADATSUMI-II will now go through commissioning in orbit: engineers will verify its radar instrument, calibrate its imagery and bring it into operational service alongside the rest of the iQPS constellation. As more satellites join the fleet, revisit times over the Asia-Pacific should continue to shorten, bringing iQPS closer to its goal of near-real-time radar coverage of the region.
For Rocket Lab, the next milestone is already in sight. With eight more iQPS launches booked and a broader manifest of commercial and government missions ahead, the company's 100th Electron flight is expected in the near future, though Rocket Lab has not announced which mission will carry that honour. Attention will also turn to Neutron, whose development will determine whether Rocket Lab can scale from small-launch leadership into the medium-lift market now dominated by larger rockets.
For skywatchers and space watchers, the flight is a reminder of how routine orbital access has become: a rocket launched before sunrise in New Zealand, a satellite deployed less than an hour later, and a constellation quietly growing — one radar eye at a time — above the Pacific.

FAQ
What is WADATSUMI-II?
WADATSUMI-II is a synthetic aperture radar (SAR) Earth-imaging satellite operated by the Japanese company iQPS. It uses radar rather than visible light, so it can image the ground through clouds and at night.
When and where did "The Sea God Surveys" launch?
The mission launched from Rocket Lab Launch Complex 1 in Mahia, New Zealand, at 5:41 a.m. NZDT on November 3, 2026, according to Rocket Lab.
Why is the 99th Electron flight significant?
It leaves Electron one flight short of 100 missions, a milestone few commercial rockets reach, and it was Rocket Lab's 20th mission of 2026, according to the company.
What does iQPS plan for its constellation?
iQPS is building a radar constellation, planned at 36 satellites, to provide high-resolution, near-real-time imagery, with eight more dedicated Electron launches booked to complete it by 2030, according to Rocket Lab.
How is radar imagery different from ordinary satellite photos?
Optical satellites need sunlight and clear skies. Radar satellites transmit their own radio signals and read the reflections, so they can image through cloud cover and darkness, which is valuable for flood mapping, maritime monitoring and disaster response.
