Exploration Environmental Control and Life Support System (ECLSS) Development and Sustaining (EEDS) Contract

The Exploration Environmental Control and Life Support System (ECLSS) Development and Sustaining (EEDS) contract supports the ongoing operational needs of the International Space Station by providing specialized engineering services for critical life support systems through the conclusion of the ISS program. It focuses on sustaining engineering and the development of unique, non-standard components including the Universal Waste Management System, Condensing Heat Exchanger, Sabatier reactor, Thermal Amine system, and the Ground Testbed, all essential for maintaining crew health, air quality, water recovery, and thermal control in the space environment. The work involves continuous design, adaptation, and technical support to ensure these systems remain functional and reliable under the demanding conditions of long-duration spaceflight. This contract, forecasted by NASA’s Johnson Space Center under the NAICS code 541715 for scientific research and development, is positioned to enable mission-critical capabilities on the ISS regardless of evolving mission requirements or system obsolescence. Although the solicitation number and detailed point of contact information are not provided, the contract’s scope is explicitly tied to supporting the final phase of the ISS program, underscoring its importance in maintaining station operations until deorbit. The services under this arrangement are not standard procurements but tailored solutions requiring deep technical expertise in environmental control and life support technologies, reflecting NASA’s commitment to sustaining human spaceflight infrastructure through its end-of-life phase.
