Technicians prepare the Space Electric Research Test (SERT-I) payload for a test in Tank Number 5 of the Electric Propulsion Laboratory at the National Aeronautics and Space Administration (NASA) Lewis Research Center. Lewis researchers had been studying different methods of electric rocket propulsion since the mid-1950s. Harold Kaufman created the first successful engine, the electron bombardment ion engine, in the early 1960s. These electric engines created and accelerated small particles of propellant material to high exhaust velocities. Electric engines have a very small amount of thrust, but once lofted into orbit by workhorse chemical rockets, they are capable of small, continuous thrust for periods up to several years.    The electron bombardment thruster operated at a 90-percent efficiency during testing in the Electric Propulsion Laboratory. The package was rapidly rotated in a vacuum to simulate its behavior in space. The SERT-I mission, launched from Wallops Island, Virginia, was the first flight test of Kaufman’s ion engine. SERT-I had one cesium engine and one mercury engine. The suborbital flight was only 50 minutes in duration but proved that the ion engine could operate in space.      The Electric Propulsion Laboratory included two large space simulation chambers, one of which is seen here. Each uses twenty 2.6-foot diameter diffusion pumps, blowers, and roughing pumps to remove the air inside the tank to create the thin atmosphere. A helium refrigeration system simulates the cold temperatures of space.

NASA’s all-electric X-57 Maxwell, in its Mod II configuration, departs Scaled Composites’ facility at Mojave Air and Space Port, en route to NASA’s Armstrong Flight Research Center in Edwards, California for delivery. The aircraft, shipped as two parts – the fuselage and the wing – was delivered to NASA Armstrong’s Research Aircraft Integration Facility, where it will be reintegrated to begin ground tests, to be followed by taxi tests, and eventually, flight tests. X-57’s Mod II configuration, the first of three primary modifications for the project, involves testing of the aircraft’s cruise electric propulsion system. The goal of the X-57 project is to share the aircraft’s electric-propulsion-focused design and airworthiness process with regulators, to advance certification approaches for distributed electric propulsion in general aviation.

Raymond Palmer, of the Electromagnetic Propulsion Division’s Plasma Flow Section, adjusts the traveling magnetic wave plasma engine being operated in the Electric Power Conversion at the National Aeronautics and Space Administration (NASA) Lewis Research Center. During the 1960s Lewis researchers were exploring several different methods of creating electric propulsion systems, including the traveling magnetic wave plasma engine. The device operated similarly to alternating-current motors, except that a gas, not a solid, was used to conduct the electricity. A magnetic wave induced a current as it passed through the plasma. The current and magnetic field pushed the plasma in one direction.    Palmer and colleague Robert Jones explored a variety of engine configurations in the Electric Propulsion Research Building. The engine is seen here mounted externally on the facility’s 5-foot diameter and 16-foot long vacuum tank. The four magnetic coils are seen on the left end of the engine. The researchers conducted two-minute test runs with varying configurations and used of both argon and xenon as the propellant.   The Electric Propulsion Research Building was built in 1942 as the Engine Propeller Research Building, often called the Prop House. It contained four test cells to study large reciprocating engines with their propellers. After World War II, the facility was modified to study turbojet engines. By the 1960s, the facility was modified again for electric propulsion research and given its current name.

The tanks were designed especially for testing ion and plasma thrusters and spacecraft. The larger 25-foot diameter tank included a 10-foot diameter test compartment to test electric thrusters with condensable propellants. The portals along the chamber floor lead to the massive exhauster equipment that pumped out the air to simulate the low pressures found in space.

The Agency reorganized in 1961 and began expanding its ranks through a massive recruiting effort. Lewis personnel increased from approximately 2,700 in 1961 to over 4,800 in 1966. Margosian, who worked with Bill Kerslake in the Electromagnetic Propulsion Division’s Propulsion Systems Section, wrote eight technical reports on mercury and electron bombardment thrusters, thermoelectrostatic generators, and a high voltage insulator.

As presented by Gerhard Heller of Marshall Space Flight Center's Research Projects Division in 1961, this chart illustrates three basic types of electric propulsion systems then under consideration by NASA. The ion engine (top) utilized cesium atoms ionized by hot tungsten and accelerated by an electrostatic field to produce thrust. The arc engine (middle) achieved propulsion by heating a propellant with an electric arc and then producing an expansion of the hot gas or plasma in a convergent-divergent duct. The electromagnetic, or MFD engine (bottom) manipulated strong magnetic fields to interact with a plasma and produce acceleration.

Engineers at NASA's Jet Propulsion Laboratory in Southern California prepare to integrate four Hall thrusters (beneath red protective covers) into the agency's Psyche spacecraft in July 2021.  Psyche is set to launch in August 2022 and will travel to its target, a metal-rich asteroid also named Psyche, under the power of solar electric propulsion. This super-efficient mode of propulsion uses solar arrays to capture sunlight that is converted into electricity to power the spacecraft's thrusters. The thrusters work by turning xenon gas, a neutral gas used in car headlights and plasma TVs, into xenon ions. As the xenon ions are accelerated out of the thruster, they create the thrust that will propel the spacecraft.  On the Psyche spacecraft, Hall thrusters will be used for the first time beyond lunar orbit, demonstrating that they could play a role in supporting future missions to deep space.  https://photojournal.jpl.nasa.gov/catalog/PIA24788

The photo on the left captures an operating electric Hall thruster identical to those that will propel NASA's Psyche spacecraft, which is set to launch in August 2022 and travel to the main asteroid belt between Mars and Jupiter. The xenon plasma emits a blue glow as the thruster operates. The photo on the right shows a similar non-operating Hall thruster. The photo on the left was taken at NASA's Jet Propulsion Laboratory in Southern California; the photo on the right was taken at NASA's Glenn Research Center.  Psyche's Hall thrusters will be the first to be used beyond lunar orbit, demonstrating that they could play a role in supporting future missions to deep space. The spacecraft is set to launch in August 2022 and will travel to its target, a metal-rich asteroid also named Psyche, under the power of solar electric propulsion. This super-efficient mode of propulsion uses solar arrays to capture sunlight that is converted into electricity to power the spacecraft's thrusters. The thrusters work by turning xenon gas, a neutral gas used in car headlights and plasma TVs, into xenon ions. As the xenon ions are accelerated out of the thruster, they create the thrust that will propel the spacecraft.  https://photojournal.jpl.nasa.gov/catalog/PIA24030
Psyche's Hall Thruster
NASA's Psyche spacecraft is photographed in July 2021 during the mission's assembly, test, and launch operations phase at the agency's Jet Propulsion Laboratory in Southern California. Set to launch in August 2022, the spacecraft will use four Hall thrusters to propel itself to the metal-rich asteroid Psyche, using solar electric propulsion. Two thrusters are visible beneath red round protective covers, after being integrated into the spacecraft.  Solar arrays on the spacecraft will capture sunlight, which will be converted into electricity to power the Hall thrusters. The thrusters work by turning xenon gas, a neutral gas used in car headlights and plasma TVs, into xenon ions. As the xenon ions are accelerated out of the thruster, they create the thrust that will propel the spacecraft.  This will be the first use of Hall thrusters beyond lunar orbit, demonstrating that they could play a role in supporting future deep space missions.  https://photojournal.jpl.nasa.gov/catalog/PIA24790
Psyche Thrusters: Integration Complete
Researchers examine the Space Plasma-High Voltage Interaction Experiment (SPHINX) satellite in the Electric Propulsion Laboratory at the National Aeronautics and Space Administration (NASA) Lewis Research Center. Lewis’ Spacecraft Technology Division designed SPHINX to study the electrical interaction of its experimental surfaces with space plasma. They sought to determine if higher orbits would improve the transmission quality of communications satellites. Robert Lovell, the Project Manager, oversaw vibrational and plasma simulation testing of the satellite in the Electric Propulsion Laboratory, seen here.     SPHINX was an add-on payload for the first Titan/Centaur proof launch in early 1974. Lewis successfully managed the Centaur Program since 1962, but this would be the first Centaur launch with a Titan booster. Since the proof test did not have a scheduled payload, the Lewis-designed SPHINX received a free ride.    The February 11, 1974 launch, however, proved to be one of the Launch Vehicle Division’s lowest days. Twelve minutes after the vehicle departed the launch pad, the booster and Centaur separated as designed, but Centaur’s two RL-10 engines failed to ignite. The launch pad safety officer destroyed the vehicle, and SPHINX never made it into orbit. Overall Centaur has an excellent success rate, but the failed SPHINX launch attempt caused deep disappointment across the center.

NASA's Psyche spacecraft, set to launch in August 2022, will travel to its target in the main asteroid belt between Mars and Jupiter under the power of super-efficient electric propulsion. This photo captures an operating electric Hall thruster identical to those that will be used to propel the Psyche spacecraft. This photo was taken at NASA's Jet Propulsion Laboratory in Southern California on May 20, 2020 with an iPhone, through the thick window of a vacuum chamber used to simulate the environment of deep space.  The thruster works by turning xenon gas, a neutral gas used in car headlights and plasma TVs, into xenon ions. As the xenon ions are accelerated out of the thruster, they create the thrust that will propel the spacecraft. The xenon plasma emits a blue glow, seen here, as it operates. An observer in space traveling behind Psyche would see the blue glow of plasma trailing behind the spacecraft. Solar arrays will provide the electricity that powers the thrusters. Hall thrusters will be used for the first time beyond lunar orbit, demonstrating that they could play a role in supporting future missions to deep space.   https://photojournal.jpl.nasa.gov/catalog/PIA23879

Researchers at the Lewis Research Center had been studying different methods of electric rocket propulsion since the mid-1950s. Harold Kaufman created the first successful engine, the electron bombardment ion engine, in the early 1960s. Over the ensuing decades Lewis researchers continued to advance the original ion thruster concept. A Space Electric Rocket Test (SERT) spacecraft was launched in June 1964 to test Kaufman’s engine in space. SERT I had one cesium engine and one mercury engine. The suborbital flight was only 50 minutes in duration but proved that the ion engine could operate in space.  This was followed in 1966 by the even more successful SERT II, which operated on and off for over ten years. Lewis continued studying increasingly more powerful ion thrusters.    These electric engines created and accelerated small particles of propellant material to high exhaust velocities. Electric engines have a very small amount of thrust and are therefore not capable of lifting a spaceship from the surface of the Earth. Once lofted into orbit, however, electric engines are can produce small, continuous streams of thrust for several years.

Lockheed Martin Missile and Space Co. employees  Joe Collingwood, at right, and Ken Dickinson retract pins in the storage base to release  a radioisotope thermoelectric generator (RTG) in preparation for hoisting operations.  This RTG and two others will be installed on the Cassini spacecraft for mechanical and  electrical verification testing in the Payload Hazardous Servicing Facility. The RTGs will  provide electrical power to Cassini on its 6.7-year trip to the Saturnian system and  during its four-year mission at Saturn. RTGs use heat from the natural decay of  plutonium to generate electric power. The generators enable spacecraft to operate at  great distances from the Sun where solar power systems are not feasible. The Cassini  mission is targeted for an Oct. 6 launch aboard a Titan IVB/Centaur expendable launch  vehicle. Cassini is built and managed by NASA’s Jet Propulsion Laboratory

      The European Space Agency's (ESA) Earth Return Orbiter (ERO) would be the biggest spacecraft to ever orbit Mars. The spacecraft would also be the first interplanetary spacecraft to rendezvous and capture hardware launched from another planet and return it to the Earth's surface, making a full round trip to Mars and back. ERO would be a multi-stage modular spacecraft equipped with both chemical and solar electric propulsion. The electric propulsion system would be the most powerful ever flown on any previous planetary mission.      ERO would carry a radiation monitor to measure the total radiation dose experienced by the spacecraft throughout the entire mission, which in addition to monitoring the health of the ERO, should provide important information on how to design systems for future human explorers. Launch is planned in 2027, entering into Mars orbit in 2029.

An electrodynamic tether uses the same principles as electric motors in toys, appliances and computer disk drives, and generators in automobiles and power plants. When electrical current is flowing through the tether, a magnetic field is produced that pushes against the magnetic field of the Earth. For ProSEDS, the current in the tether results by virtue of the voltage generated when the tether moves through the Earth's magnetic field at more than 17,000 mph. This approach can produce drag thrust generating useable power. Since electrodynamic tethers require no propellant, they could substantially reduce the weight of the spacecraft and provide a cost-effective method of reboosting spacecraft. The initial flight of ProSEDS is scheduled to fly aboard an Air Force Delta II rocket in summer of 2002. In orbit, ProSEDS will deploy from a Delta II second stage. It will be a 3.1-mile (5 kilometer) long, ultrathin base-wire tether cornected with a 6.2-mile (10 kilometer) long nonconducting tether. The ProSEDS experiment is managed by the Space Transportation Directorate at the Marshall Space Flight Center.

Researcher Charles Michels operates a coaxial plasma gun rig in Cell SW-13 of the Engine Research Building at the National Aeronautics and Space Administration (NASA) Lewis Research Center. From 1962 to 1967 NASA Lewis investigated coaxial plasma guns powered by conventional capacitor banks. The studies were part of a larger effort to identify electromagnetic accelerators for space propulsion. NASA worked with General Dynamics, General Electric, General Motors, and Republic Aviation on the project.    NASA Lewis conducted a research program to determine which factors influenced the coaxial gun’s efficiency and analyze the acceleration process. The system had not previously been used for propulsion applications. The single-shot gun’s fast gas valve and capacitor banks with variable-delay ignition source permitted the evaluation of gun performance under controllable propellant quantity and distribution conditions.    The coaxial plasma gun was the most basic type of electromagnetic accelerator. It included a charged capacitor in series with a pair of coaxial electrodes. An electrical breakdown occurred when gas was admitted to the inter-electrode region. The gas instantly became a good conductor and formed a conducting sheet that separated the magnetic field from the open region beyond. The highly-conducting gas was basically expelled by the force of the magnetic pressure. This type of thruster could operate at the high instantaneous power levels without decreasing its average power level.

The mobile launcher (ML) is reflected in the sunglasses of a construction worker with JP Donovan at NASA's Kennedy Space Center in Florida. A crane is lifting the Interim Cryogenic Propulsion Stage Umbilical (ICPSU) up for installation on the tower of the ML. The last of the large umbilicals to be installed, the ICPSU will provide super-cooled hydrogen and liquid oxygen to the Space Launch System (SLS) rocket's interim cryogenic propulsion stage, or upper stage, at T-0 for Exploration Mission-1. The umbilical is located at about the 240-foot-level of the mobile launcher and will supply fuel, oxidizer, gaseous helium, hazardous gas leak detection, electrical commodities and environment control systems to the upper stage of the SLS rocket during launch. Exploration Ground Systems is overseeing installation of the umbilicals on the ML.
