This photo gives an overhead look at an RS-88 development rocket engine being test fired at NASA's Marshall Space Flight Center in Huntsville, Alabama, in support of the Pad Abort Demonstration (PAD) test flights for NASA's Orbital Space Plane (OSP). The tests could be instrumental in developing the first crew launch escape system in almost 30 years. Paving the way for a series of integrated PAD test flights, the engine tests support development of a system that could pull a crew safely away from danger during liftoff. A series of 16 hot fire tests of a 50,000-pound thrust RS-88 rocket engine were conducted, resulting in a total of 55 seconds of successful engine operation. The engine is being developed by the Rocketdyne Propulsion and Power unit of the Boeing Company. Integrated launch abort demonstration tests in 2005 will use four RS-88 engines to separate a test vehicle from a test platform, simulating pulling a crewed vehicle away from an aborted launch. Four 156-foot parachutes will deploy and carry the vehicle to landing. Lockheed Martin is building the vehicles for the PAD tests. Seven integrated tests are plarned for 2005 and 2006.

The Integrated Powerhead Demonstration engine was fired at 100 percent power for the first time July 12, 2006 at NASA Stennis Space Center's E Test Complex. The IPD, which can generate about 250,000 pounds of thrust, is a reusable engine system whose technologies could one day help Americans return to the moon, and travel to Mars and beyond. The IPD engine has been designed, developed and tested through the combined efforts of Pratt & Whitney Rocketdyne and Aerojet, under the direction of the Air Force Research Laboratory and NASA's Marshall Space Flight Center.

The upper empennage, or tail section of the plane, and engine bay is surrounded by a blue gantry that is used to assist with ground installation and removal of the X-59’s lower empennage and engine. Once fully assembled, the X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land. This aircraft is the centerpiece of NASA’s Quesst mission.

Here is an image of the X-59’s 13-foot General Electric F414 engine as the team prepares for a fit check. Making sure components, like the aircraft’s hydraulic lines, which help control functions like brakes or landing gear, and wiring of the engine, fit properly is essential to the aircraft’s safety. Once complete, the X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land.

This closeup of Boeing Phantom Works' unique X-48B Blended Wing Body technology demonstrator shows off its unusual engine placement and supercritical airfoil.

This image shows the X-59 aircraft’s lower empennage structure, or tail section of the plane, that was installed. The stabilators, the outer surfaces also seen in the photo, attach to the lower empennage and are used to help regulate the aircraft pitch which controls the up and down movement of the motion of the plane. The 13-foot engine will pack 22,000 pounds of propulsion and energy and power the X-plane to its planned cruising speed of Mach 1.4. Once complete, the X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land. This aircraft is the centerpiece of NASA’s Quesst mission.

A quality inspector inspects the GE F-414 engine nozzle after installation at Lockheed Martin’s Skunk Works facility in Palmdale, California. Once the aircraft and ground testing are complete, the X-59 will undergo flight testing, which will demonstrate the plane’s ability to fly supersonic - faster than the speed of sound - while reducing the loud sonic boom. This could enable commercial supersonic air travel over land.

This image shows the X-59’s engine inlet from the aft view, which is the rear of the airplane, looking forward. Once the aircraft and ground testing are complete, the X-59 will undergo flight testing, which will demonstrate the plane’s ability to fly supersonic - faster than the speed of sound - while reducing the loud sonic boom.

A development model rover that is part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration took its first autonomous drive around the Mars Yard at the agency's Jet Propulsion Laboratory in Southern California in June 2023. The CADRE team tested a new wheel design, surface navigation software, and mobility capabilities, among other aspects of the project. Engineer Kristopher Sherrill is shown recording video of the test. The rover being tested is similar in size and appearance to the flight models of the CADRE rovers, which are still being built. Slated to arrive at the Moon in spring 2024 as part of NASA's CLPS (Commercial Lunar Payload Services) initiative, CADRE is designed to demonstrate that multiple robots can cooperate and explore together autonomously – without direct input from human mission controllers. A trio of the miniature solar-powered rovers, each about the size of a carry-on suitcase, will explore the Moon as a team, communicating via radio with each other and a base station aboard a lunar lander. By taking simultaneous measurements from multiple locations, CADRE will also demonstrate how multirobot missions can record data impossible for a single robot to achieve – a tantalizing prospect for future missions.

Engineers for NASA's MarCO technology demonstration display a full-scale mechanical mock-up of the small craft in development as part of NASA's next mission to Mars. Mechanical engineer Joel Steinkraus and systems engineer Farah Alibay are on the team at NASA's Jet Propulsion Laboratory, Pasadena, California, preparing twin MarCO (Mars Cube One) CubeSats for a March 2016 launch. MarCO is the first interplanetary mission using CubeSat technologies for small spacecraft. The briefcase-size MarCO twins will ride along on an Atlas V launch vehicle lifting off from Vandenberg Air Force Base, California, with NASA's next Mars lander, InSight. The mock-up in the photo is in a configuration to show the deployed position of components that correspond to MarCO's two solar panels and two antennas. During launch, those components will be stowed for a total vehicle size of about 14.4 inches (36.6 centimeters) by 9.5 inches (24.3 centimeters) by 4.6 inches (11.8 centimeters). After launch, the two MarCO CubeSats and InSight will be navigated separately to Mars. The MarCO twins will fly past the planet in September 2016 just as InSight is descending through the atmosphere and landing on the surface. MarCO is a technology demonstration mission to relay communications from InSight to Earth during InSight's descent and landing. InSight communications during that critical period will also be recorded by NASA's Mars Reconnaissance Orbiter for delayed transmission to Earth. InSight -- an acronym for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport -- will study the interior of Mars to improve understanding of the processes that formed and shaped rocky planets, including Earth. After launch, the MarCO twins and InSight will be navigated separately to Mars. Note: After thorough examination, NASA managers have decided to suspend the planned March 2016 launch of the Interior Exploration using Seismic Investigations Geodesy and Heat Transport (InSight) mission. The decision follows unsuccessful attempts to repair a leak in a section of the prime instrument in the science payload. http://photojournal.jpl.nasa.gov/catalog/PIA19389

Engineers and technicians prepare one of three small lunar rovers that are part of a NASA technology demonstration called CADRE (Cooperative Autonomous Distributed Robotic Exploration). Mechanical engineer Kristopher Sherrill, left, and technician Leroy Montalvo lower an enclosure over the upside-down rover in a clean room at the agency's Jet Propulsion Laboratory in Southern California on Jan. 29, 2025. CADRE aims to prove that a group of robots can collaborate to gather data without receiving direct commands from mission controllers on Earth. Its trio of rovers will use their cameras and ground-penetrating radars to send back imagery of the lunar surface and subsurface while testing out the novel software systems that enable them to work together as a team autonomously. Before embarking on the first leg of a multistage journey to the Moon, each rover was mated to its deployer system, which will lower it via tether from an Intuitive Machines lander onto the dusty lunar surface. Engineers flipped each rover-deployer pair over and attached it to an aluminum plate for safe transit. The rovers were then sealed into protective metal-frame enclosures that were fitted snuggly into metal shipping containers and loaded onto a truck for the drive to Intuitive Machines' Houston facility. A division of Caltech in Pasadena, California, JPL manages CADRE for the Game Changing Development program within NASA's Space Technology Mission Directorate in Washington. The technology demonstration was selected under the agency's Lunar Surface Innovation Initiative, which was established to expedite the development of technologies for sustained presence on the lunar surface. CADRE will launch as a payload on the third lunar lander mission by Intuitive Machines, called IM-3, under NASA's CLPS (Commercial Lunar Payload Services) initiative, which is managed by the agency's Science Mission Directorate, also in Washington. The agency's Glenn Research Center in Cleveland and its Ames Research Center in Silicon Valley, California, both supported the project. Motiv Space Systems designed and built key hardware elements at the company's Pasadena facility. Clemson University in South Carolina contributed research in support of the project.

The briefcase-size MarCO twins were designed to ride along with NASA's next Mars lander, InSight. Its planned March 2016 launch was suspended. InSight -- an acronym for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport -- will study the interior of Mars to improve understanding of the processes that formed and shaped rocky planets, including Earth. Note: After thorough examination, NASA managers have decided to suspend the planned March 2016 launch of the Interior Exploration using Seismic Investigations Geodesy and Heat Transport (InSight) mission. The decision follows unsuccessful attempts to repair a leak in a section of the prime instrument in the science payload. http://photojournal.jpl.nasa.gov/catalog/PIA20342
