S68-34582 (1968) --- With its exterior removed, the Apollo portable life support system (PLSS) can be easily studied. The PLSS is worn as a backpack over the Extravehicular Mobility Unit (EMU) a multi-layered spacesuit used for outside-the-spacecraft activity. JSC photographic frame no. S68-34582 is a wider view of the exposed interior working parts of the PLSS and its removed cover.

Astronaut Edwin E. Aldrin Jr., wearing an Extravehicular Mobility Unit (EMU), verifies fit of the Portable Life Support System (PLSS) strap length during lunar surface training at the Kennedy Space Center. Aldrin is the prime crew lunar module pilot of the Apollo 11 lunar landing mission. Aldrin's PLSS backpack is attached to a lunar weight simulator.

S70-56965 (December 1970) --- Drawing of the newly developed Buddy Secondary Life Support System (BSLSS). The life-sustaining system will be provided for the first time on the Apollo 14 lunar landing mission. The two flexible hoses, to be used on the second Apollo 14 extravehicular activity (EVA), will be among the paraphernalia on the Modular Equipment Transporter (MET) or two-wheeled workshop, and readily accessible in an emergency. During EVAs the Portable Life Support System (PLSS) supplies the astronaut with breathing and suit-pressurizing oxygen and water flow for the liquid-cooling garment -- a suit of knitted long underwear with thin tubing woven in the torso and limbs. The tubes carry water from a reservoir in the PLSS, and the circulating water serves to carry the astronaut's metabolic heat to a heat exchanger in the PLSS. Before the BSLSS was devised, the emergency tank was required to furnish not only suit pressure and breathing oxygen, but also cooling through a high oxygen flow rate. The BSLSS, by sharing the water supply between the two crewmen, stretches the time of the emergency oxygen from about 40 minutes to 60 to 75 minutes.

Labeled cutaway line drawing of the Shuttle extravehicular mobility unit (EMU) identifies its various components and equipment. The portable life support system (PLSS) and protective layers of fabric (thermal micrometeoroid garment (TMG)) incorporated in this extravehicular activity (EVA) space suit are shown.

S69-25878 (23 Feb. 1969) --- Astronaut Russell L. Schweickart, lunar module pilot of the Apollo 9 prime crew, wears the Extravehicular Mobility Unit (EMU) which he will use during his scheduled Apollo 9 extravehicular activity. In addition to the space suit and bubble helmet, the EMU also includes a Portable Life Support System back pack, an Oxygen Purge System (seen atop the PLSS), and a Remote Control Unit on his chest. This equipment will be completely independent of the spacecraft during Schweickart's EVA. He will be secured only by a tether line. When this photograph was taken, Schweickart was suited to participate in an Apollo 9 Countdown Demonstration Test.

Firefighters are like astronauts. They both face dangerous, even hostile environments such as a building full of fire and the vacuum of space. They are both get breathing air from tanks on their backs. Early in the 1970's, NASA began working to improve firefighter breathing systems, which had hardly changed since the 1940s. NASA's Johnson Space Center conducted a 4-year program that applied technology from the portable life support systems used by Apollo astronauts on the moon. The new breathing system is made up of an air bottle, a frame and harness, a face mask, and a warning device. The new system weighs less than 20 pounds, one-third less than the old gear. The new air bottle provides 30 minutes of breathing air, as much as the old system. Like a good hiker's backpack, the new system puts the weight on the firefighter's hips rather than the shoulders. The face mask provides better visibility and the warning device lets the firefighter know when air in the bottle is low. Though they have made many design modifications and refinements, manufacturers of breathing apparatus still incorporate the original NASA technology.

CAPE CANAVERAL, Fla. – In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, STS-130 Mission Specialist Kathryn "Kay" Hire, at left, participates in a bench review, standard familiarization training on the hardware and equipment that will fly on her mission, during the crew equipment interface test. Tranquility, the payload for the STS-130 mission, is a pressurized module that will provide room for many of the International Space Station's life support systems. The module was built for the European Space Agency by Thales Alenia Space in Turin, Italy. The cupola, a unique work station with six windows on its sides and one on top, is attached to the end of Tranquility. It resembles a circular bay window and will provide a vastly improved view of the station's exterior. Just under 10 feet in diameter, the module will accommodate two crew members and portable workstations that can control station and robotic activities. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects.

CAPE CANAVERAL, Fla. – In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, Kennedy Director Bob Cabana addresses the invited guests at a ceremony transferring the ownership of node 3 for the International Space Station, looming in the background, from the European Space Agency, or ESA, to NASA. Seated, from left, are William Dowdell, deputy for Operations, International Space Station and Spacecraft Processing, Kennedy; Bernardo Patti, head of International Space Station, Program Department, ESA; and Secondino Brondolo, head of the Space Infrastructure, Thales Alenia Space Italy. Node 3 is named "Tranquility" after the Sea of Tranquility, the lunar landing site of Apollo 11. The payload for the STS-130 mission, Tranquility is a pressurized module that will provide room for many of the International Space Station's life support systems. The module was built for ESA by Thales Alenia Space in Turin, Italy. Attached to one end of Tranquility is a cupola, a unique work station with six windows on its sides and one on top. The cupola resembles a circular bay window and will provide a vastly improved view of the station's exterior. Just under 10 feet in diameter, the module will accommodate two crew members and portable workstations that can control station and robotic activities. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects.
