The contributions of NASA and Kennedy Space Center were stitched into the fabric of one of the nation’s most recognizable symbols, when flags from Florida’s Spaceport were sewn into an American Flag recovered near ground zero following the Sept. 11, 2001, attacks. In this image, the National 9/11 Flag was raised over the Rocket Garden at the Kennedy Space Center Visitor Complex after Florida’s contribution was added. The flag is now a part of the permanent collection of the National September 11 Memorial Museum at the World Trade Center site.

2021年9月11日 Saturn at Night Image Credit: NASA, JPL-Caltech, Space Science Institute, Mindaugas Macijauskas Explanation: Still bright in planet Earth’s night skies, good telescopic views of Saturn and its beautiful rings often make it a star at star parties. But this stunning view of Saturn’s rings and night side just isn’t possible from telescopes closer to the Sun than the outer planet. They can only bring Saturn’s day into view. In fact, this image of Saturn’s slender sunlit crescent with night’s shadow cast across its broad and complex ring system was captured by the Cassini spacecraft. A robot spacecraft from planet Earth, Cassini called Saturn orbit home for 13 years before it was directed to dive into the atmosphere of the gas giant on September 15,…

The pressure vessel is the primary structure for Orion’s crew module, joined together using state-of-the-art welding by technicians from lead contractor Lockheed Martin. Both the Orion spacecraft and the Space Launch System (SLS) rocket are making progress towards Artemis missions to the Moon. With the spacecraft for the Artemis I and II missions manufactured as part of the design and development phase, the Artemis III pressure vessel is the first crew module structure off the line in the long-term production phase. Next, it will ship to NASA’s Kennedy Space Center where teams will begin integration of Orion’s systems. Orion, SLS, and the Exploration Ground Systems are foundational elements of NASA’s Moon to Mars exploration approach. Artemis I will be the first integrated flight test of…

2021年9月10日 Rosetta’s Comet in View Image Credit & Copyright: Rolando Ligustri (CARA Project, CAST) Explanation: Faint comet Churyumov-Gerasimenko (67P) sweeps past background stars in the constellation Taurus and even fainter distant galaxies in this telescopic frame from September 7. About 5 years ago, this comet’s 4 kilometer spanning, double-lobed nucleus became the final resting place of robots from planet Earth, following the completion of the historic Rosetta mission to the comet. After wandering out beyond the orbit of Jupiter, Churyumov-Gerasimenko is now returning along its 6.4 year periodic orbit toward its next perihelion or closest approach to the Sun, on November 2. On November 12, the comet’s perigee, its closest approach to Earth, will bring it within about 0.42 astronomical units. Telescopes should still be…

玛丽·W·杰克逊：纪念历史上的黑人大学的领袖

ByNASA中文

Mary W. Jackson grew up in Hampton, Virginia and attended the historically black college Hampton Institute (now Hampton University), earning bachelor of science degrees in mathematics and physical science. Each year, we celebrate National Historically Black Colleges and Universities (HBCUs) Week under the leadership of the White House Initiative on HBCUs and with input from the President’s Board of Advisors on HBCUs and its conference sponsors. It provides a forum to exchange information and share innovations among and between institutions. This year HBCU Week runs Sept. 7-10. After graduating from Hampton, Jackson took a rather circuitous route to becoming a celebrated NASA engineer – from school teacher to ‘human computer’ in the now famous, Langley Memorial Aeronautical Laboratory’s segregated West Area Computing section in 1951….

为12月发射詹姆斯·韦伯太空望远镜做准备

为12月发射詹姆斯·韦伯太空望远镜做准备

在成功完成最后的测试后，可以看到NASA的詹姆斯·韦伯太空望远镜正准备运往发射场。 图片来源：NASA/Chris Gunn NASA计划于2021年12月18日将詹姆斯·韦伯太空望远镜送入轨道，作为未来十年的主要深空观测站。 在韦伯望远镜最近成功完成其严格的测试方案之后，NASA与阿丽亚娜航天公司协调确定了新的发射日期——这是该任务的一个重要转折点。在此之前，阿丽亚娜空间公司于7月下旬成功发射了阿丽亚娜5号火箭，并计划在韦伯望远镜之前发射。今年7月的发射是阿丽亚娜5号自2020年8月以来的首次发射。 韦伯望远镜是NASA与欧空局（European Space Agency）和加拿大航天局合作的国际项目，将由阿丽亚娜5号火箭从南美洲东北部海岸的法属圭亚那的欧洲太空港发射。欧空局提供阿丽亚娜5号。 这个高度复杂的太空望远镜目前正在诺斯罗普·格鲁曼公司位于加利福尼亚州雷东多海滩的设施中进行最后的收放配置。 “韦伯望远镜是一项堪称典范的任务，象征着毅力的缩影，”韦伯望远镜在华盛顿NASA总部的项目主管格雷戈里·L·罗宾逊（Gregory L. Robinson）说。“我被我们敬业的团队和我们的全球伙伴关系所鼓舞，他们使这一令人难以置信的努力成为可能。我们一起克服了技术障碍，也克服了冠状病毒大流行期间的挑战。我也感谢国会对我的坚定支持。现在我们有了一个天文台和一枚准备发射的火箭，我期待着这个重要的日子和即将到来的惊人的科学。” 韦伯望远镜团队正在为装运作业做准备，在此期间，天文台将进行最后的收尾程序，并为前往发射场打包。将携带韦伯望远镜进入太空的阿丽亚娜5号火箭的主要部件已经从欧洲安全抵达法属圭亚那的库鲁。 韦伯望远镜团队正在为运输工作做准备，在此期间，天文台将经历最后的收尾程序，并为其前往发射场的旅程打包。将把韦伯望远镜送入太空的阿丽亚娜5号火箭的主要部件已经从欧洲安全抵达法属圭亚那的库鲁。 韦伯望远镜的革命性技术将探索宇宙历史的每一个阶段——从太阳系内部到早期宇宙中最遥远的可观测星系，以及介于这两者之间的一切。韦伯望远镜将揭示新的和意想不到的发现，并帮助人类了解宇宙的起源和我们在其中的位置。 如欲了解更多有关韦伯望远镜任务的更多信息，请访问: www.webb.nasa.gov 有关韦伯望远镜的建造和工程的信息，请访问: www.nasa.gov/webb 参考来源： https://www.nasa.gov/press-release/nasa-readies-james-webb-space-telescope-for-december-launch

Apurva Varia joined the Goddard Space Flight Center in 2002 as a propulsion engineer. For 13 years, he analyzed, designed, and tested the propulsion systems for spacecraft, including the Solar Dynamics Observatory, Magnetospheric Multiscale, and Deep Space Climate Observatory. He was the first deaf engineer to monitor and analyze the telemetry from a propulsion system inside an uncrewed spacecraft in a NASA Mission Operation Center. In 2016, he became a mission director for three spacecraft including the Parker Solar Probe, which launched on a journey to study our Sun in 2018.

Instrumentation technician Michael Hodgins performs installation measures on the trans-sonic truss-braced wing (TTBW) model at Langley Research Center’s 14×22 subsonic wind tunnel. The unique design of the aircraft’s wings reduces drag during flight, which in turn reduces fuel consumption by up to 10 percent. This concept is part of an ongoing initiative by NASA, industry partners, and academia to make the future of aviation more environmentally friendly through the Sustainable Flight National Partnership (SFNP). The SFNP will expand research for sustainable aviation by developing and testing new technologies for aircraft, new automation tools for greener and safer airspace operations, and sustainable energy options for aircraft propulsion. The TTBW will undergo a variety of aerodynamic testing as researchers continue to test key flight components such as…

M16特写

ByNASA中文

2021年9月9日 M16 Cose Up Image Credit & Copyright: Martin Pugh Explanation: A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, M16 is also known as The Eagle Nebula. This beautifully detailed image of the region adopts the colorful Hubble palette and includes cosmic sculptures made famous in Hubble Space Telescope close-ups of the starforming complex. Described as elephant trunks or Pillars of Creation, dense, dusty columns rising near the center are light-years in length but are gravitationally contracting to form stars. Energetic radiation from the cluster stars erodes material near the tips, eventually exposing the embedded new stars. Extending from the ridge of bright emission left of center is another dusty starforming column known as the Fairy…

2021年9月8日 The Deep Sky Toward Andromeda Image Credit & License: Stefan Ziegenbalg Explanation: What surrounds the Andromeda galaxy? Out in space, Andromeda (M31) is closely surrounded by several small satellite galaxies, and further out it is part of the Local Group of Galaxies — of which our Milky Way galaxy is also a member. On the sky, however, gas clouds local to our Milky Way appear to surround M31 — not unlike how water clouds in Earth’s atmosphere may appear to encompass our Moon. The gas clouds toward Andromeda, however, are usually too faint to see. Enter the featured 45-degree long image — one of the deeper images yet taken of the broader Andromeda region. This image, sensitive to light specifically emitted by hydrogen gas,…
