Landsat 9号卫星就位进行封装

ByNASA中文

Inside the Integrated Processing Facility at Vandenberg Space Force Base in California, the Landsat 9 spacecraft is moved into position for encapsulation on Aug. 16, 2021. The two halves of the United Launch Alliance (ULA) payload fairing will surround and encase Landsat 9 to protect it during launch atop the ULA Atlas V rocket. Landsat 9 will launch on the Atlas V rocket from Space Launch Complex 3 at Vandenberg in September of this year. The launch is being managed by NASA’s Launch Services Program based at Kennedy Space Center, America’s multi-user spaceport. The Landsat 9 satellite, managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, will continue the nearly 50-year legacy of previous Landsat missions. It will monitor key natural and economic…

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.

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…

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….

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. Learn more about Apurva Varia’s career at NASA. #DeafAwareness Image Credit: Bill Hrybyk 阿普尔瓦·瓦利亚（Apurva Varia）于2002年加入戈达德太空飞行中心，担任推进工程师。13年来，他分析、设计和测试了航天器的推进系统，包括太阳动力学观测站、磁层多尺度观测站和深空气候观测站。 他是第一个在NASA任务操作中心监测和分析无人驾驶航天器内的推进系统遥测的聋哑工程师。2016年，他成为三个航天器的任务主管，其中包括帕克太阳探测器，该探测器于2018年开始了研究太阳的旅程。 了解更多关于阿普尔瓦·瓦利亚在NASA职业生涯的信息。 #DeafAwareness 图片来源:Bill Hrybyk

跨音速桁架式机翼可能有助于减少燃料消耗

ByNASA中文

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…

This Mastcam-Z image shows a sample of Mars rock inside the sample tube on Sept. 1, 2021 – the 190th sol, or Martian day, of the mission. The image was taken after coring concluded but prior to an operation that vibrates the drill bit and tube to clear the tube’s lip of any residual material. The bronze-colored outer-ring is the coring bit. The lighter-colored inner-ring is the open end of the sample tube, and inside is a rock core sample slightly thicker than a pencil. A portion of the tube’s serial number – 266 – can be seen on the top side of tube’s wall. Additional images taken after the arm completed sample acquisition were inconclusive due to poor sunlight conditions. Another round of images…

约翰娜·路赫特：杰出工程师

ByNASA中文

According to Dictionary.com, extraordinaire means: outstanding or remarkable in a particular capacity – an apt description of engineer Johanna Lucht. “My ‘extraordinary’ is finding efficient ways to improve how we gather and evaluate aviation data,” said Lucht. Lucht, who was born deaf, never thought she would work for NASA. Born in Germany, where resources for deaf people were limited at the time, Johanna developed an understanding of mathematics before she acquired language. It was that passion for math and the ability to face challenges that led to her eventual study of computer science, and paved her road to NASA. After an internship at NASA’s Armstrong Flight Research Center, she was offered a position. In 2017, Johanna became the first deaf engineer to carry out an…
