Under the agreement, KULR will supply its KULR ONE Space (K1S) battery systems, engineered to NASA safety standards, to power critical spacecraft subsystems throughout the mission’s operational lifetime. <img alt="KULR ARGO" height="278" src="https://ml.globenewswire.com/Resource/Download/271b7bde-dc58-470c-b416-0b40958b92d0/kulr-argo.png" width="600" data-dpi="220" data-caption="KULR Technology Selected by Argo Space Corp. as Battery Provider for Orbital Transport Space Mission" data-filename="KULR ARGO.png" /> “Building a new class of spacecraft to provide transport and maneuver meant designing it from the ground up. KULR had the best solution on the market for a battery that met our unique needs for performance, reliability, and cost. We’re excited to work with them on our first, our next, and our future spacecraft.” – Kirby Carlisle, Argo Chief Operating Officer. The selection reflects KULR’s growing role as a trusted battery partner for the commercial space industry. The global space battery market is <a href="https://www.globenewswire.com/Tracker?data=_DksLFQFqAtMU_RtNGFVTYXZ-gQlTW41eHp_aa7S6hsd-V47cIyLYqe-lcmUsUtJ6C6ZYbz1ldSJMw1-HMI0xRrUNTQ52GgSeD5bQ-k3uVnUb4tIp97hWxIbDt_Mdsrp6HznpAm-ep4CyNPWNP9-bzKoWkv371muAyrQkha1sMs=" rel="nofollow" target="_blank" title="projected">projected</a> to grow to $5.61 billion by 2030, driven by surging demand for crewed and uncrewed deep space programs. Missions beyond LEO (low Earth orbit) impose uniquely severe requirements on energy storage: systems must sustain operation across extreme temperature cycling, prolonged vacuum exposure, and high-radiation environments. “Being selected by Argo Space is an exciting milestone for KULR,” said Dr. Will Walker, Chief Technology Officer of KULR. “Our heritage at NASA and our decade of work developing battery systems that meet the most stringent space safety standards make KULR uniquely positioned to support missions where there is zero margin for error. This engagement validates the KULR ONE Space platform and opens a new frontier of opportunity as commercial space programs push beyond Earth orbit.” The KULR ONE Space (K1S) battery system is built on KULR’s lightweight “REACH” battery architecture, which provides high energy density and low mass. K1S systems incorporate strategically selected cells with Initial Lot Assessment (ILA), Lot Acceptance Testing (LAT), and NASA WI-37A Cell Screening protocols. “Space demands that every component perform flawlessly throughout the mission profile with no opportunity for servicing or replacement,” said Peter Hughes, Vice President of Engineering at KULR Technology Group. “Our team has spent years refining the K1S architecture specifically for these environments — integrating our thermal knowledge, NASA WI-37A screened cells, and comprehensive flight readiness testing in-house. This is exactly the program our KULR ONE Space platform was built for.” This agreement builds on KULR’s demonstrated space heritage, which includes supplying battery systems that meet NASA safety requirements for Artemis’ crewed spaceflight, an active rideshare mission flight demonstration with Exolaunch aboard a SpaceX launch vehicle, and ongoing supply relationships with multiple commercial space operators. KULR’s Webster, Texas manufacturing and R&amp;D facility will support production and qualification testing for the Argo battery systems. About KULR Technology Group, Inc. KULR Technology Group, Inc.
