Space Life Support Systems Market Global Report 2026

The space life support systems market size has grown rapidly in recent years. It will grow from $3.51 billion in 2025 to $3.88 billion in 2026 at a compound annual growth rate (CAGR) of 10.3%. The growth in the historic period can be attributed to increasing human spaceflight missions, expansion of space station programs, rising government investment in space exploration, growing demand for astronaut safety systems, and development of long-duration space missions.

The space life support systems market size is expected to see strong growth in the next few years. It will grow to $5.66 billion in 2030 at a compound annual growth rate (CAGR) of 9.9%. The growth in the forecast period can be attributed to increasing lunar and Mars exploration missions, expanding commercial spaceflight activities, growing demand for sustainable resource recycling, rising investments in deep-space exploration, and increasing development of permanent extraterrestrial habitats. Major trends in the forecast period include development of advanced closed-loop life support systems, increasing water recovery and recycling efficiency, development of regenerative oxygen generation technologies, enhanced carbon dioxide removal and air revitalization, and integration of advanced thermal and humidity control systems.

The increasing government investments in human space exploration missions are expected to propel the growth of the space life support systems market in the coming years. Government investments in human space exploration missions refer to public funding allocated by national space agencies to develop crewed spacecraft, space stations, lunar habitats, and other technologies required to safely transport and sustain astronauts during space missions. Government investments in human space exploration missions are increasing due to the strategic need to strengthen national space capabilities, as countries seek to enhance technological leadership, scientific advancement, and long-term space presence. Government investments in human space exploration missions support space life support systems by driving the development and deployment of advanced life support technologies required to sustain astronauts during long-duration space missions. For instance, in January 2025, according to Novaspace, a France-based space intelligence company, global government investment in space reached $135 billion in 2024, representing a 10% increase compared with 2023. Therefore, the increasing government investments in human space exploration missions are driving the growth of the space life support systems market.

Major companies operating in the space life support systems market are focusing on advancing life support technologies, such as regenerative environmental control and life support systems (ECLSS), to improve air and water recycling, enhance resource recovery, reduce reliance on resupply missions, and support safe long-duration human spaceflight. Regenerative environmental control and life support systems (ECLSS) are integrated systems designed to recover, purify, and reuse essential resources such as air and water while regulating the spacecraft environment to maintain crew health and safety. For instance, in March 2024, Blue Origin, a US-based aerospace and space technology company, achieved significant testing milestones for the Orbital Reef space station’s life support system under its Space Act Agreement with NASA. The testing assessed technologies and designs for cleaning, reclaiming, and storing air and water for human spaceflight and included a water contaminant oxidation system, water tank, urine water recovery system, and trace contaminant control system.

In April 2025, Sierra Space, a US-based commercial space company, partnered with Honda and Tec-Masters to advance regenerative energy and life support technologies for space exploration. Through this partnership, Sierra Space, Honda, and Tec-Masters aimed to test Honda’s high-differential-pressure water electrolysis system aboard the International Space Station (ISS) to produce oxygen and hydrogen from water and support the development of regenerative systems for long-duration human spaceflight and future lunar surface activities. Honda Motor Co. Ltd. is a Japan-based mobility and technology company developing regenerative fuel cell and water electrolysis technologies for space applications, while Tec-Masters Inc. is a US-based engineering and technology company providing technical solutions and support for aerospace, defense, and space missions.
