Over the past decade, global space launch cadences have grown dramatically, frequently placing multiple payloads into orbit on a single booster. Robust Space Domain Awareness (SDA) and precise characterization of resident space objects are vital to safeguarding the orbital environment.
To confront this emerging national security risk, a team of scientists at Lawrence Livermore National Laboratory (LLNL) partnered with Rocket Lab and the U.S. Space Force (USSF) Space Systems Command (SSC) to deliver an optical payload for the VICTUS HAZE tactically responsive space (TacRS) mission under the Space Safari program office. Rocket Lab achieved the successful launch of their Electron spacecraft in the unprecedented time of under 17 hours from notice, well exceeding the goal of launch within 24 hours.
This historic mission aims to simulate the inspection of an on-orbit threat by rapidly launching an inspector spacecraft, commissioning it within 72 hours, and then conducting complex rendezvous and proximity operations (RPO) on orbit within 84 hours to pursue, monitor, approach and image the target in detail. Rocket Lab's Puma spacecraft successfully completed the first mission phases faster than the deadlines set by the Space Force, setting records and delivering new standards in responsive space. In early mission phases, Rocket Lab was able to gain tracking of the target spacecraft using LLNL's optical payload and its onboard software capabilities, demonstrating essential precision navigation and control for inspection operations.
"We are honored to have contributed the imaging payload for this innovative mission," said Ben Bahney, leader of the LLNL Space Program. "Tactically responsive space is what we do."
The mission is part of a broader effort led by USSF to leverage the United States' innovative commercial space industry to improve the service's ability to respond to security challenges. With an emphasis on speed, flexibility and operational relevance, the new threat landscape requires space teams to fundamentally shift how they think about launch, payload integration and mission execution.
The Space Program at LLNL is uniquely positioned to meet this objective with advanced optics systems designed for rapid deployment and integration. The VICTUS HAZE optical imaging payload uses LLNL's monolithic telescopes, which are fabricated out of a single silica substrate, to deliver exceptional mechanical stability at a low-cost.
"The LLNL Space Program is thrilled to be a part of this critical TacRS demonstration in partnership with USSF and Rocket Lab", said Cohl Hatala, project manager and lead mechanical engineer for the LLNL Space Program. "The capability of our optical payload makes it the perfect candidate for VICTUS HAZE."
Within 24 hours of launch, the team completed the commissioning of the payload, demonstrating how the optics system can support rapid action and decision-making in space operations. By pairing a fast launch capability with a responsive imaging payload, the mission tested not only launch readiness but also the ability to gather and assess information quickly once on orbit. The optical payload successfully demonstrated angles-only navigation using live-feed images and an algorithm embedded within its payload electronics, enabling closed-loop control between the payload and the spacecraft. This LLNL payload capability allowed the Puma vehicle to rapidly acquire the target by using the optical telescope to command and point the satellite in the right direction.
LLNL continues to play a vital role by supporting ongoing payload operations during the rendezvous and proximity operations. The findings are expected to help refine future tactically responsive space missions.
As the space domain grows more active and contested, missions like VICTUS HAZE are key to provide space operators a practical test of whether the U.S. can detect, track and respond to orbital threats with greater speed and precision.
