The X-43A/Pegasus combination dropped into the Pacific Ocean after losing control early in the first free-flight attempt

The first X-43A hypersonic research aircraft and its modified Pegasus booster rocket were carried aloft by NASA's NB-52B carrier aircraft from Dryden Flight Research Center at Edwards Air Force Base, Calif., on June 2, 2001 for the first of three high-speed free flight attempts. About an hour and 15 minutes later the Pegasus booster was released from the B-52 to accelerate the X-43A to its intended speed of Mach 7. Before this could be achieved, the combined Pegasus and X-43A "stack" lost control about eight seconds after ignition of the Pegasus rocket motor. The mission was terminated and explosive charges ensured the Pegasus and X-43A fell into the Pacific Ocean in a cleared Navy range area. A NASA investigation board is being assembled to determine the cause of the incident. Work continues on two other X-43A vehicles, the first of which could fly by late 2001. Central to the X-43A program is its integration of an air-breathing "scramjet" engine that could enable a variety of high-speed aerospace craft, and promote cost-effective access to space. The 12-foot, unpiloted research vehicle was developed and built for NASA by MicroCraft Inc., Tullahoma, Tenn. The booster was built by Orbital Sciences Corp. at Chandler, Ariz.

First Flight of a Liquid Propellant Rocket

Dr. Robert H. Goddard and a liquid oxygen-gasoline rocket in the frame from which it was fired on March 16, 1926, at Auburn, Massachusetts. From 1930 to 1941, Dr. Goddard made substantial progress in the development of progressively larger rockets, which attained altitudes of 2400 meters, and refined his equipment for guidance and control, his techniques of welding, and his insulation, pumps and other associated equipment. In many respects, Dr. Goddard laid the essential foundations of practical rocket technology. He is considered one of the fathers of rocketry along with Konstantin Tsiolovsky (1857-1935) and Hermann Oberth (1894-1989). <a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.

Pegasus Mated to B-52 Mothership - First Flight

The Pegasus air-launched space booster is carried aloft under the right wing of NASA's B-52 carrier aircraft on its first captive flight from the Dryden Flight Research Center, Edwards, California. The first of two scheduled captive flights was completed on November 9, 1989. Pegasus is used to launch satellites into low-earth orbits cheaply. In 1997, a Pegasus rocket booster was also modified to test a hypersonic experiment (PHYSX). An experimental "glove," installed on a section of its wing, housed hundreds of temperature and pressure sensors that sent hypersonic flight data to ground tracking facilities during the experiment’s flight.

Altimeter Chart for Ingenuity's First Flight

This altimeter chart shows data from the first flight of NASA's Ingenuity Mars Helicopter, which occurred on April 19, 2021. The Ingenuity Mars Helicopter was built by JPL, which also manages this technology demonstration project for NASA Headquarters. It is supported by NASA's Science Mission Directorate, Aeronautics Research Mission Directorate, and Space Technology Mission Directorate. NASA's Ames Research Center and Langley Research Center provided significant flight performance analysis and technical assistance during Ingenuity's development. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. https://photojournal.jpl.nasa.gov/catalog/PIA24587

Ingenuity's First Flight Recorded by Mastcam-Z

This image was taken after the first flight of NASA's Ingenuity Mars Helicopter — and the first powered, controlled flight on another planet. It was captured by Mastcam-Z, a pair of zoomable cameras aboard NASA's Perseverance Mars rover, on April 19, 2021. Flying in a controlled manner on Mars is far more difficult than flying on Earth. The Red Planet has significant gravity (about one-third that of Earth's), but its atmosphere is just 1% as dense as Earth's at the surface. Stitched together from multiple images, the mosaic is not white balanced; instead, it is displayed in a preliminary calibrated version of a natural color composite, approximately simulating the colors of the scene that we would see if we were there viewing it ourselves. Arizona State University in Tempe leads the operations of the Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego.

Linear Aerospike SR-71 Experiment (LASRE) dumps water after first in-flight cold flow test

The NASA SR-71A successfully completed its first cold flow flight as part of the NASA/Rocketdyne/Lockheed Martin Linear Aerospike SR-71 Experiment (LASRE) at NASA's Dryden Flight Research Center, Edwards, California on March 4, 1998. During a cold flow flight, gaseous helium and liquid nitrogen are cycled through the linear aerospike engine to check the engine's plumbing system for leaks and to check the engine operating characterisitics. Cold-flow tests must be accomplished successfully before firing the rocket engine experiment in flight. The SR-71 took off at 10:16 a.m. PST. The aircraft flew for one hour and fifty-seven minutes, reaching a maximum speed of Mach 1.58 before landing at Edwards at 12:13 p.m. PST. "I think all in all we had a good mission today," Dryden LASRE Project Manager Dave Lux said. Flight crew member Bob Meyer agreed, saying the crew "thought it was a really good flight." Dryden Research Pilot Ed Schneider piloted the SR-71 during the mission. Lockheed Martin LASRE Project Manager Carl Meade added, "We are extremely pleased with today's results. This will help pave the way for the first in-flight engine data-collection flight of the LASRE."

How differential deflection of the inboard and outboard leading-edge flaps affected the handling qualities of this modified F/A-18A was evaluated during the first check flight in the Active Aeroelastic Wing program at NASA's Dryden Flight Research Center.

The third iteration of the X-38, V-131R, glides down under a giant parafoil towards a landing on Rogers Dry Lake near NASAÕs Dryden Flight Research Center during its first free flight Nov. 2, 2000. The X-38 prototypes are intended to perfect technology for a planned Crew Return Vehicle (CRV) ÒlifeboatÓ to carry a crew to safety in the event of an emergency on the International Space Station. Free-flight tests of X-38 V-131R are evaluating upgraded avionics and control systems and the aerodynamics of the modified upper body, which is more representative of the final design of the CRV than the two earlier X-38 test craft, including a simulated hatch atop the body. The huge 7,500 square-foot parafoil will enable the CRV to land in the length of a football field after returning from space. The first three X-38Õs are air-launched from NASAÕs venerable NB-52B mother ship, while the last version, V-201, will be carried into space by a Space Shuttle and make a fully autonomous re-entry and landing.
