保护地球，探索宇宙，发现文明
In this March 2021 image, Flight Research Inc.’s Bell OH-58C Kiowa helicopter hovered over a helipad after completing an urban air mobility (UAM) approach at NASA’s Armstrong Flight Research Center. The Advanced Air Mobility National Campaign used the helicopter as a representative vehicle to better understand how a future UAM vehicle will need to operate in...
Credit：NASA 2020年，美国国家航空航天局（NASA）在月球到火星探测战略方面取得了重大进展，实现了阿尔忒弥斯（Artemis）计划的任务目标，取得了能够造福于人类的重大科学进步，并恢复了美国本土的载人航天发射能力。与此同时，NASA的专门小组迅速采取了行动，协助国家抗击新型冠状病毒肺炎（COVID-19）疫情。 NASA局长吉姆·布里登斯廷（Jim Bridenstine）表示：“NASA在疫情期间表现出的韧性和毅力给全国人民留下了深刻印象。我们与美国商业伙伴一起创造了历史，作出了开创性的发现，推动了科学进步，进一步深化了航空研究和技术研发，甚至还参与了抗击COVID-19疫情的斗争。我们度过了充满挑战的一年，取得了令人难以置信的成就，并为持续的成功开辟了道路。” NASA对美国联邦政府应对COV...
Dec. 11, 2020, marks the 50th anniversary of NASA’s Langley Research Center’s 14×22 Subsonic Wind Tunnel. The facility is used to assess aerodynamic performance of aircraft over a wide range of takeoff, landing, cruise, and high angle-of-attack conditions. It can provide acoustic, tethered free-flight, and forced-oscillation testing, motorsports researc...
An array of 960 microphones is seen here off the end of runway 11 at Boeing’s research facility near Glasgow, Montana. The microphones were used by NASA to record the sound of a low-flying 787-10 Dreamliner passing overhead as part of the Chicago-based company’s 2020 ecoDemonstrator program during late August and early September. NASA researchers are studyin...
We’re celebrating National Aviation Day! After all, we are the National Aeronautics and Space Administration. Aviation and aeronautics are as much a part of our mission as space travel. This visualization is generated from a supercomputer simulation of the X-57 “Maxwell” electric experimental aircraft. Just as electric cars are becoming more and more c...
X-59 QueSST降落在跑道上的示意图 来源：Lockheed Martin NASA30多年来的首架大型有人驾驶的X-plane，经过高级管理人员周四在华盛顿NASA总部举行的重大项目审查后，已获准进行系统的最后组装和整合。 被称为关键决策点D（KDP-D）的管理评审是X-59静音超音速技术(QueSST)飞机在2020年底官方再次开会批准2021年的首飞之前的最后一个程序障碍。 “随着KDP-D项目的完成，我们已经证明该项目如期进行，计划周密，步入正轨。我们已经准备就绪，为国家的航空旅行大众继续这项历史性的研究任务。”美国宇航局航空航天局副局长鲍勃·皮尔斯（Bob Pearce）说。 X-59的形状可以将到达地面的音爆声的响度降低到轻柔的重击声（如果能听到的话）。 它将飞越美国部分社区，以从地面上的传感...
In the high desert of California, some of the most important aircraft in aviation history have been built and flown. NASA’s X-59 QueSST (short for Quiet SuperSonic Technology) is an experimental piloted aircraft designed to fly faster than sound without producing the annoying – if not alarming – sonic booms of previous supersonic aircraft. It is the latest c...
Today is National Aviation Day and progress is ongoing in the next evolution of air mobility – all thanks to emerging 3D printing technology. This image of a full-scale model of Langley Aerodrome No. 8 is being constructed at NASA’s Langley Research Center. The LA-8 model will to contribute to the agency’s Urban Air Mobility (UAM) initiative. “It’s definitel...
For NASA Wallops Flight Facility research pilot Rich Rogers, July 26 brought an end to one of the things in his life that he has greatly enjoyed – flying Navy and NASA aircraft. After a few quick laps around the Wallops airfield in the B200 King Air, Rogers settled the aircraft onto the runway and taxied to the hangar, along the way receiving a water cannon ...
A drone moves high above downtown Reno, Nevada, on the afternoon of June 23, 2019 as part of NASA’s TCL-4 (Technology Capability Level) operation. TCL-4 involves flight testing multiple UAS (Unmanned Aerial Systems) in higher-density urban areas for tasks such as newsgathering, package delivery and large-scale contingency mitigation. The next and final test ...
