In this 1986 artist's concept, the Orbital Maneuvering Vehicle (OMV), undergoes changeout of the Propulsion Module outside the Space Shuttle Cargo Bay. As envisioned by Marshall Space Flight Center plarners, the OMV would be a remotely-controlled free-flying space tug which would place, rendezvous, dock, and retrieve orbital payloads.

Early Program Development
In this 1986 artist's concept, the Orbital Maneuvering Vehicle (OMV), is shown without its main propulsion module. Essentially two propulsion vehicles in one, the OMV could be powered by a main propulsion module , or, in its short range vehicle configuration shown here, use its own hydrazine and cold gas thrusters. As envisioned by Marshall Space Flight Center plarners, the OMV would be a remotely-controlled free-flying space tug which would place, rendezvous, dock, and retrieve orbital payloads.

This illustration shows NASA's Lunar Flashlight carrying out a trajectory correction maneuver with the Moon and Earth in the background. Powered by the small satellite's four thrusters, the maneuver is needed to reach lunar orbit.  Lunar Flashlight launched Nov. 30, 2022, and will take about four months to reach its science orbit to seek out surface water ice in the darkest craters of the Moon's South Pole. A technology demonstration, the small satellite, or SmallSat, will use a reflectometer equipped with four lasers that emit near-infrared light in wavelengths readily absorbed by surface water ice.  To achieve the mission's goals with the satellite's limited amount of propellent, Lunar Flashlight will employ an energy-efficient near-rectilinear halo orbit, taking it within 9 miles (15 kilometers) of the lunar South Pole and 43,000 miles (70,000 kilometers) away at its farthest point. Only one other spacecraft has employed this type of orbit: NASA's Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) mission, which launched in June 2022.  https://photojournal.jpl.nasa.gov/catalog/PIA25258

KENNEDY SPACE CENTER, FLA. -  In the Orbiter Processing Facility, the left-hand Orbital Maneuvering System (OMS) pod  is maneuvered toward the engine interfaces on the orbiter Discovery for installation.  The Orbital Maneuvering System provides the thrust for orbit insertion, orbit circularization, orbit transfer, rendezvous, deorbit, abort to orbit and abort once around.  It can provide up to 1,000 pounds of propellant to the aft reaction control system.  Each pod contains one OMS engine and the hardware needed to pressurize, store and distribute the propellants to perform the velocity maneuvers.

KENNEDY SPACE CENTER, FLA. - At Vandenberg Air Force Base in California, workers maneuver the Demonstration of Autonomous Rendezvous Technology (DART) spacecraft, suspended by a crane, over the upper stage in preparation for launch on the Orbital Sciences Pegasus XL.  The Pegasus XL will launch DART into a circular polar orbit of approximately 475 miles.   Built for NASA by Orbital Sciences Corporation, DART was designed as an advanced flight demonstrator to locate and maneuver near an orbiting satellite. DART weighs about 800 pounds and is nearly 6 feet long and 3 feet in diameter.  DART is designed to demonstrate technologies required for a spacecraft to locate and rendezvous, or maneuver close to, other craft in space. Results from the DART mission will aid in the development of NASA’s Crew Exploration Vehicle and will also assist in vehicle development for crew transfer and crew rescue capability to and from the International Space Station.

KENNEDY SPACE CENTER, FLA. --  Inside NASA Kennedy Space Center’s Orbiter Processing Facility Bay 1, workers secure the overhead crane to the sling placed round the forward reaction control system that will be installed on Atlantis.  When ready, the shuttle equipment will be lifted for installation.   The forward reaction control system is located in the forward fuselage nose area.  During ascent of the space shuttle, it provides the thrust for attitude (rotational) maneuvers (pitch, yaw and roll) and for small velocity changes along the orbiter axis (translation maneuvers).

CAPE CANAVERAL, Fla. – The forward reaction control system, or FRCS, will be removed from space shuttle Endeavour's forward fuselage nose area in NASA Kennedy Space Center's Orbiter Processing Facility 2.  The FRCS provides the thrust for attitude (rotational) maneuvers (pitch, yaw and roll) and for small velocity changes along the orbiter axis (translation maneuvers). Endeavour is designated as the shuttle for the STS-130 mission, targeted for launch in February 2010.  Photo credit: NASA/Jack Pfaller

This Skylab-4 onboard photograph depicts Astronaut Gerald Carr testing Astronaut Maneuvering Equipment (M509) by flying it around under weightless conditions in the Orbital Workshop. The M509 experiment was an operational study to evaluate and conduct an in-orbit verification of the utility of various maneuvering techniques to assist astronauts in performing tasks that were representative of future extravehicular activity requirements.
