Gemini 12 was designed to perform rendezvous and docking with the Agena target vehicle, to conduct three Extravehicular Activity ( EVA ) operations, to conduct a tethered stationkeeping exercise, to perform docked maneuvers using the Agena propulsion system to change orbit, and demonstrate an automatic reentry.

He is expert in Extravehicular Activity ( Spacewalk ), Spacesuit design, and Rendezvous navigation.

In 2000 he was assigned to the Astronaut Office Extravehicular Activity Branch, while maintaining a position as Lead ESA astronaut in Houston.

From the year 2000 on, he was assigned to the Astronaut Office EVA ( Extravehicular Activity ) Branch, while maintaining a position as Lead ESA astronaut in Houston.

STS-103 had four scheduled Extravehicular Activity ( EVA ) days where four crew members worked in pairs on alternating days to renew and refurbish the telescope.

Following STS-103, he served as Chief of the Extravehicular Activity Branch in the Astronaut Office.

Following STS-109, Grunsfeld served as an instructor in the Extravehicular Activity Branch, and worked on the Orbital Space Plane, exploration concepts, and technologies for use beyond low earth orbit in the Advanced Programs Branch.

From 1997-2001 Harbaugh served as Manager of the Extravehicular Activity Project Office, with program management responsibility for all aspects of NASA ’ s spacewalk industry, including spacesuits, tools, training, tasks and operations for the Space Shuttle, the International Space Station, and future planetary missions.

Prior to his first space flight assignment, Massimino served in the Astronaut Office Robotics Branch, and in the Astronaut Office Extravehicular Activity ( EVA ) Branch.

His technical assignments included: scientific equipment operator for high altitude research on the WB-57F aircraft ( 1980 – 1981 ); astronaut medical support for the first four Shuttle missions ( 1980 – 1982 ); astronaut office representative for Extravehicular Mobility Unit ( spacesuit ) and Extravehicular Activity ( EVA ) procedures and development, including thermal vacuum testing of the suit ( 1981 – 1984 ); astronaut office representative for the Payload Assist Module ( PAM-D ) procedures and development ( 1982 – 1983 ); astronaut office representative for Shuttle Mission Simulator ( SMS ) development ( 1983 ); support crewman for STS-8 ; CAPCOM for STS-8 and STS-9 ; Remote Manipulator System ( RMS ) hardware and software development team ( 1983 ); Manned Maneuvering Unit ( MMU ) development team ( 1983 ); Deputy Director of NASA Government-furnished and Contractor-furnished Equipment ( 1982 – 1983 ); Chief of Astronaut Public Appearances ( 1985 – 1987 ); Head, Astronaut Office Space Station Manned Systems Division, and Health Maintenance Facility ( 1987 – 1989 ); Astronaut Office representative on space crew selection and retention standards for Space Station ( 1989 – 1991 ).

Fisher logged over 170 hours in space, including 11 hours and 52 minutes of Extravehicular Activity ( EVA ).

In 1991 she certified as a Space Shuttle Test Project Engineer ( TPE ) and headed the checkout of the Extravehicular Mobility Units ( spacesuits ) and Russian Orbiter Docking System.

It consists of a Hard Upper Torso ( HUT ) assembly, a Primary Life Support System ( PLSS ) which incorporates the life support and electrical systems, arm sections, gloves, an Apollo-style " bubble " helmet, the Extravehicular Visor Assembly ( EVVA ), and a soft Lower Torso Assembly ( LTA ), incorporating the Body Seal Closure ( BSC ), waist bearing, brief, legs, and boots.

In the U. S. space program, Nomex has been used for the Thermal Micrometeoroid Garment on the Extravehicular Mobility Unit ( in conjunction with Kevlar and Gore-Tex ) and ACES pressure suit, both for fire and extreme environment ( water immersion to near vacuum ) protection, and as thermal blankets on the payload bay doors, fuselage, and upper wing surfaces of the Space Shuttle Orbiter.

The other DTO's included in this test are DTO 672, Extravehicular Mobility Unit ( EMU ) Electrical Cuff Checklist and DTO 833, EMU Thermal Comfort and EVA Worksite Thermal Environment.

The successful checkout of the Extravehicular Mobility Units ( EMUs ), the Simplified Aid for EVA Rescue ( SAFER ) units, the Canadarm ( RMS ), the Orbiter Space Vision System ( OSVS ) and the Orbiter Docking System ( ODS ) were all completed nominally.

The Extravehicular Mobility Unit ( EMU ) is an independent anthropomorphic spacesuit that provides environmental protection, mobility, life support, and communications for astronauts performing extra-vehicular activity ( EVA ) in Earth orbit.

ILC also designed and manufactured the Space Suit Assembly portion of the Extravehicular Mobility Unit ( EMU ), worn by astronauts during performance of extra-vehicular activity ( EVA ) on Space Shuttle missions and on the International Space Station.

In 1977, ILC Dover, in conjunction with Hamilton Standard, began development and manufacture of the Extravehicular Mobility Unit ( EMU ), the suit worn by astronauts during Space Shuttle and Space Station extra-vehicular activity ( EVA ).

The space suit used for EVA during shuttle missions is the Extravehicular Mobility Unit ( EMU ), which has two parts: the space suit assembly ( SSA ), manufactured by ILC, and the life support system ( LSS ), manufactured by Hamilton Sundstrand ( previously Hamilton Standard ).

An EVA visor assembly similar to that used today on the Shuttle / ISS Extravehicular Mobility Unit was worn over the pressure helmet, but Apollo EVA gloves were used.

When the United States resumed EVAs on April 7, 1983, astronauts started using an Extravehicular Mobility Unit ( EMU ) for self-contained life support independent of the spacecraft.

ILC Dover, in nearby Frederica, is the producer of fabrics for military and aerospace uses, along with being the primary contractor for production of the Apollo and Skylab spacesuits, as well as the spacesuit assembly for the Space Shuttle's Extravehicular Mobility Unit ( EMU ).

In 1965, Komarov worked with Yuri Gagarin in supervising preparations for the flight of Voskhod 2, which carried out the first attempt of an Extravehicular activity in outer space.

Perhaps most notably, Vectran is used as one of the five layers in NASA's Extravehicular Mobility Unit ( spacesuit ) designed by Hamilton Sundstrand and was the fabric used for the airbags on the Mars Pathfinder in 1997

Once installed and activated, the ISS airlock became the primary path for International Space Station space walk entry and departure for U. S. spacesuits, which are known as Extravehicular Mobility Units, or EMUs.

The Shuttle Reference Manual contains ECLSS sections on: Crew Compartment Cabin Pressurization, Cabin Air Revitalization, Water Coolant Loop System, Active Thermal Control System, Supply and Waste Water, Waste Collection System, Waste Water Tank, Airlock Support, Extravehicular Mobility Units, Crew Altitude Protection System, and Radioisotope Thermoelectric Generator Cooling and Gaseous Nitrogen Purge for Payloads.

This was the first Space Shuttle mission during which a spacewalk was conducted, and the first in which the Extravehicular Mobility Unit ( EMU ) was used.

He flew as a scientific equipment operator in the WB 57-F earth resources aircraft and served as the Astronaut Office representative in the Space Shuttle Extravehicular Mobility Unit ( space suit ) development effort.

These tasks included two Extravehicular Activities ( EVA's ) in which Dr. van Hoften attached to the Remote Manipulator System ( RMS ) performed the first manual grapple and manual deployment of a satellite in orbit.
