STS109-322-029 (6 March 2002) --- Astronaut John M. Grunsfeld, STS-109 payload commander, participates in the third of five space walks to perform work on the Hubble Space Telescope (HST). The third overall STS-109 extravehicular activity (EVA) marked the second of three for Grunsfeld, who was joined by astronaut Richard M. Linnehan on them all. On this particular walk, astronauts Grunsfeld and Linnehan turned off the telescope in order to replace its power control unit or PCU, the heart of the HST’s power system.
This is an onboard photo of the Hubble Space Telescope (HST) power control unit (PCU), the heart of the HST's power system. STS-109 payload commander John M. Grunsfeld, joined by Astronaut Richard M. Lirnehan, turned off the telescope in order to replace its PCU while participating in the third of five spacewalks dedicated to servicing and upgrading the HST. Other upgrades performed were: replacement of the solar array panels; replacement of the Faint Object Camera (FOC) with a new advanced camera for Surveys (ACS); and installation of the experimental cooling system for the Hubble's Near-Infrared Camera and Multi-Object Spectrometer (NICMOS), which had been dormant since January 1999 when its original coolant ran out. The telescope was captured and secured on a work stand in Columbia's payload bay using Columbia's robotic arm, where crew members completed the system upgrades. The Marshall Space Flight Center had the responsibility for the design, development, and construction of the HST, which is the most complex and sensitive optical telescope ever made, to study the cosmos from a low-Earth orbit. The HST detects objects 25 times fainter than the dimmest objects seen from Earth and provides astronomers with an observable universe 250 times larger than is visible from ground-based telescopes, perhaps as far away as 14 billion light-years. Launched March 1, 2002 the STS-109 HST servicing mission lasted 10 days, 22 hours, and 11 minutes. It was the 108th flight overall in NASA's Space Shuttle Program.

CAPE CANAVERAL, Fla. – In Orbiter Processing Facility bay No. 2, auxiliary power unit 3, or APU3, is in place on space shuttle Endeavour for the STS-126 mission. The auxiliary power unit is a hydrazine-fueled, turbine-driven power unit that generates mechanical shaft power to drive a hydraulic pump that produces pressure for the orbiter's hydraulic system. There are three separate APUs, three hydraulic pumps and three hydraulic systems, located in the aft fuselage of the orbiter. When the three auxiliary power units are started five minutes before lift-off, the hydraulic systems are used to position the three main engines for activation, control various propellant valves on the engines and position orbiter aerosurfaces. The auxiliary power units are not operated after the first orbital maneuvering system thrusting period because hydraulic power is no longer required. One power unit is operated briefly one day before deorbit to support checkout of the orbiter flight control system. One auxiliary power unit is restarted before the deorbit thrusting period. The two remaining units are started after the deorbit thrusting maneuver and operate continuously through entry, landing and landing rollout. On STS-126, Endeavour will deliver a multi-purpose logistics module to the International Space Station. Launch is targeted for Nov. 10. Photo credit: NASA/Kim Shiflett

The Pathfinder solar-powered research aircraft settles in for landing on the bed of Rogers Dry Lake at the Dryden Flight Research Center, Edwards, California, after a successful test flight Nov. 19, 1996. The ultra-light craft flew a racetrack pattern at low altitudes over the flight test area for two hours while project engineers checked out various systems and sensors on the uninhabited aircraft. The Pathfinder was controlled by two pilots, one in a mobile control unit which followed the craft, the other in a stationary control station. Pathfinder, developed by AeroVironment, Inc., is one of several designs being evaluated under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program.
The electro-mechanical actuator, a new electronics technology, is an electronic system that provides the force needed to move valves that control the flow of propellant to the engine. It is proving to be advantageous for the main propulsion system plarned for a second generation reusable launch vehicle. Hydraulic actuators have been used successfully in rocket propulsion systems. However, they can leak when high pressure is exerted on such a fluid-filled hydraulic system. Also, hydraulic systems require significant maintenance and support equipment. The electro-mechanical actuator is proving to be low maintenance and the system weighs less than a hydraulic system. The electronic controller is a separate unit powering the actuator. Each actuator has its own control box. If a problem is detected, it can be replaced by simply removing one defective unit. The hydraulic systems must sustain significant hydraulic pressures in a rocket engine regardless of demand. The electro-mechanical actuator utilizes power only when needed. A goal of the Second Generation Reusable Launch Vehicle Program is to substantially improve safety and reliability while reducing the high cost of space travel. The electro-mechanical actuator was developed by the Propulsion Projects Office of the Second Generation Reusable Launch Vehicle Program at the Marshall Space Flight Center.

Launch team members are seated at the Auxiliar Power Units/Hydraulics consoles inside Firing Room 1 of the Launch Control Center at NASA’s Kennedy Space Center in Florida on Dec. 13, 2021. They are participating in a joint integrated simulation for the Artemis I launch that covered both cryogenic loading and terminal countdown portions of prelaunch activities. Members of NASA’s mission management team and launch team conducted the simulation together. The Kennedy team was certified for the Artemis I launch. During Artemis I, the agency’s Orion spacecraft will lift off from Kennedy aboard NASA’s most powerful rocket – the Space Launch System – to fly farther than any spacecraft built for humans has ever flown. Through NASA’s Artemis missions, the agency, along with commercial and international partners, will establish a sustainable human presence on the Moon to prepare for missions to Mars.
