Our Shuttle Carrier Aircraft ferries the Space Shuttle Endeavour over the Johnson Space Center in Houston in this Sept. 20, 2012, image. Endeavour’s end destination was the California Science Center, where it sits on display. The shuttle Endeavour brought the first parts of the International Space Station to space and completed 25 missions. On its final flight to the California Science Center 10 years ago, Endeavour was escorted by a combination of F/A-18s and an F-15 from NASA’s Armstrong Flight Research Center in Edwards, California. Those aircraft were flown by NASA Armstrong pilots, while center photographers and videographers documented the orbiter’s final journey.

T-38 planes are a fixture of astronaut training, assisting pilots and mission specialists to think quickly in changing situations. Here, our T-38s fly in formation above the Space Launch System (SLS) rocket on Launch Pad 39B. The SLS and Orion spacecraft for the Artemis I mission will launch no earlier than Aug. 29, 2022. Astronaut Andrew Morgan posted this and two other photos on Twitter on Aug. 25, 2022, saying “This week we flew over @NASAArtemis, thanking the @nasa centers across the country that put this Moon rocket on @NASAKennedy’s pad and celebrating the upcoming test flight!” Image credit: NASA/Josh Valcarcel T-38飞机是宇航员训练的一个固定项目，协助飞行员和任务专家在不断变化的情况下快速思考。在这里，我们的T-38飞机在39B发射台上的太空发射系统（SLS）火箭上方编队飞行。用于阿尔忒弥斯一号任务的SLS和猎户座飞船将不早于2022年8月29日发射。 宇航员安德鲁·摩根于2022年8月25日在推特上发布了这张照片和另外两张照片，称“本周我们飞越了@NASAArtemis，感谢全国各地的@nasa 中心将这枚月球火箭放在@NASAKennedy 的平台上，并庆祝即将进行的试飞！” 影像来源：NASA/Josh Valcarcel

The supersonic X-1E research aircraft was the last of NASA’s experimental X-1 series of aircraft. From 1955-1958, it made 26 flights and one captive flight (attached to a carrier aircraft). Research flights took place over what is now NASA’s Armstrong Flight Research Center in Edwards, California. In this photo from November 2021, the X-1E looks toward the full Moon.

为下一代飞行做准备

为下一代飞行做准备

ByNASA中文

Before NASA’s quiet supersonic X-59 aircraft takes to the skies, plenty of testing happens to ensure a safe first flight. One part of this safety check is to analyze data collected for the X-59’s flight control system through low-speed wind tunnel tests. The X-59 is central to NASA’s Quesst mission to expand supersonic flight and provide regulators with data to help change existing national and international aviation rules that ban commercial supersonic flight over land. The aircraft is designed to produce a gentle thump instead of a sonic boom. Recently, Lockheed Martin’s Skunk Works facility in Palmdale, California, completed low-speed wind tunnel tests of a scale model of the X-59’s forebody. The tests provided measurements of how wind flows around the aircraft nose and confirmed…

介绍Quesst：速度从未如此安静

介绍Quesst：速度从未如此安静

ByNASA中文

Evoking the experimental nature of flight testing and the spirit of aeronautical exploration, Quesst is what NASA is calling its mission to enable supersonic air travel over land. This new moniker – complete with an extra “s” to represent “supersonic” – draws its inspiration from NASA’s long legacy of supersonic flight research. Quesst, which replaces the mission’s original name: the Low-Boom Flight Demonstration, effectively conveys the purpose and excitement of a journey that could lead to a dramatic reduction in passenger air travel time. With the introduction of Quesst comes a new mission identity — a blue and green signature mark that represents the elements of Quesst. The mission graphic displays stylized supersonic shockwaves encircling the research aircraft, above a community of homes. The imagery…

A top view shows the wing loading test configuration of a F/A-18E from the Naval Air Systems Command (NAVAIR) in Patuxent River, Maryland. While the aircraft was in NASA’s Armstrong Flight Research Center Flight Loads Laboratory in Edwards, California, it underwent the center’s biggest load calibrations tests. That testing was needed before the aircraft could serve as a test vehicle for determining if it could safely manage maneuvers and proposed upgrades.

This colorized schlieren image is of a small-scale model of NASA’s X-59 Quiet SuperSonic Technology (QueSST) airplane taken inside NASA Glenn Research Center’s 8- by- 6-foot Supersonic Wind Tunnel during a recent boom test. The multiple-week campaign produced data sets and shockwave visuals that engineers from the agency’s Commercial Supersonic Technology project will use to validate boom-reducing technologies and sonic boom-predicting capabilities. The boom test at NASA Glenn was one of the final X-59 QueSST wind tunnel evaluations as the agency prepares for the aircraft’s first flight later this year, leading to further low-boom validation in flight in 2023. 这幅彩色纹影图像是NASA X-59静音超音速技术（QUSST）飞机的小型模型，拍摄于NASA格伦研究中心的8乘6英尺超音速风洞中，当时正在进行音爆测试。这次为期数周的实验产生了数据集和冲击波图像，来自NASA的商业超音速技术项目的工程师将使用这些数据集来验证减爆技术和音爆预测能力。在格伦进行的音爆测试是X-59 QueSST最后的风洞评估之一，该机构为今年晚些时候X-59 QueSST的首次飞行做准备，并将在2023年的飞行中进一步低音爆验证。 Image Credit: Quentin Schwinn, NASA Glenn/ATS 影像来源：Quentin Schwinn, NASA Glenn/ATS

小小的（火星）直升飞机

Ingenuity, the helicopter that arrived on the Red Planet on the Mars Perseverance rover, has made nine flights on Mars. Ingenuity’s historic achievement is the first powered helicopter flight on a terrestrial body other than Earth. According to Håvard F. Grip, Ingenuity Chief Pilot, and Ken Williford, Perseverance Deputy Project Scientist, Flight 9, which occurred in July 2021, was unlike the flights that came before it. It broke our records for flight duration and cruise speed, and it nearly quadrupled the distance flown between two airfields. But what really set the flight apart was the terrain that Ingenuity had to negotiate during its 2 minutes and 46 seconds in the air – an area called “Séítah” that would be difficult to traverse with a ground…

In a series of flights between June 1-6, 2021, Stratodynamics Inc. launched its HiDRON stratospheric glider from a high-altitude balloon at Spaceport America in New Mexico. HiDRON carried technology supported by NASA’s Flight Opportunities program for the first time. The uncrewed HiDRON stratospheric glider from Stratodynamics is designed to release from a sounding balloon at near-space altitude, enabling a controlled descent for technology payloads aboard. The glider also achieves higher velocity than a balloon flight alone – one of the reasons NASA-supported researchers from the University of Kentucky chose Stratodynamics as the flight provider for testing of turbulence detection instruments. According to the Federal Aviation Administration: “Clear air turbulence is air movement created by atmospheric pressure, jet streams, air around mountains, cold or warm weather…
