The International Space Station (ISS) continues to mature and operate its life support equipment. Major events occurring between February 2006 and February 2007 are discussed in this paper, as are updates from previously ongoing hardware anomalies. This paper addresses the major ISS operation events over the last year. Impact to overall ISS operations is also discussed.

The International Space Station (ISS) United States Laboratory module has been under test for approximately two years in the Space Station Processing Facility (SSPF) at NASA Kennedy Space Center (KSC) preparing for launch. Preparation activities for closing out the Environmental Control and Life Support (ECLS) system have included Closed Hatch testing to verify the capability of the life support equipment to support the crew, final manufacturing steps, and the close-out process itself. These activities were accomplished by an integrated Boeing and NASA team, located at the Johnson Space Center (Houston, Texas), Marshall Space Flight Center (Huntsville, Alabama) and Kennedy Space Center, Florida. On December 13, the Laboratory module hatches were sealed prior to loading into the Shuttle Orbiter payload bay for launch on February 7, 2001.

The International Space Station (ISS) underwent a dramatic buildup in life support equipment since the delivery and activation of the U.S. Laboratory module in February 2001, followed by the Joint Airlock in July 2001. Since Laboratory activation, several Environmental Control and Life Support (ECLS) equipment failures have occurred. This paper addresses these failures, occurring through February 2002, and, where known, the root causes, with particular emphasis on probable micro-gravity causes are highlighted. Impact to overall ISS operations and proposed or accomplished fixes also are discussed.

The International Space Station (ISS) program consists of three distinct phases. Phase 1 consists of the joint Shuttle-Mir missions. Phase 2 establishes the ISS initial research capability with a three person crew permanent presence. Phase 3 completes the assembly, establishing six person crew permanent presence with multiple International Partner (IP) research facilities. Phase 1 is nearing completion, while Phase 2 is in the subsystem delivery and element integration stage. This paper provides a status of the U.S. Environmental Control and Life Support (ECLS) system for Phases 2 and 3 of the ISS program, focusing on updates and changes in the past year.

Future human space exploration missions present significant challenges for life support system (LSS) development. These life support systems will require incorporation of regenerative technologies to reduce or eliminate expendables and be low risk, demonstrating high reliability and long-term performance capability. A regenerative LSS for Space Station is a key step toward meeting these future space exploration requirements. In the development of the Space Station regenerative LSS, the challenges have been both technical and budgetary. Currently, the International Space Station Alpha (ISSA) program will consist of three Phases. Phase I will be MIR/Shuttle Orbiter flights with United States (US) crews attending to the various US flight experiments on-board the MIR. Phase II will consist mostly of Russian launched modules and the United States (US) Laboratory module. Phase III will launch the US Habitat module to implement US regenerative LSS.

The International Space Station continues to build up and operate its life support equipment. Major events occurring between February 2004 and February 2005 are discussed in this paper, as are updates from previously ongoing hardware anomalies. This paper addresses the major events of the last year of ISS operation. Impact to overall station operations is discussed.

The International Space Station continues to build up its life support equipment capability. Several ECLS equipment failures have occurred since Lab activation in February 2001. Major problems occurring between February 2001 and February 2002 were discussed in reference 1. Major problems occurring between February 2002 and February 2003 are discussed in this paper, as are updates from previously ongoing unresolved problems. This paper addresses failures, and root cause, with particular emphasis on likely micro-gravity causes. Impact to overall station operations and proposed and accomplished fixes will also be discussed.

With the advent of the Space Station Program, regenerative Environmental Control and Life Support Systems (ECLSS) are being considered to minimize logistics requirements. In addition to the potential to improve system performance and reduce life-cycle costs, rationale for adopting regenerative techniques . is based on sixteen years of National Aeronautics and Space Administration (NASA) sponsored regenerative ECLSS hardware development. This technological progress has been obtained through the Space Station Preprototype (SSP) and the Regenerative Life Support Evaluation (RLSE) programs, and ongoing Advanced Preprototype subsystem development and testing. The SSP program focused on regenerative life support techniques to satisfy projected goals of long-duration earth orbital missions.
