升空！JPSS-2和LOFTID成功发射

ByNASA中文 2022年11月16日

The Moon makes a stunning backdrop for the successful launch of the third in a series of polar-orbiting weather satellites for the National Oceanic and Atmospheric Administration (NOAA) and our Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) on Nov. 10 at 4:49 a.m. EST from Vandenberg Space Force Base in California. A United Launch Alliance Atlas V rocket carried the Joint Polar Satellite System (JPSS)-2 and LOFTID. JPSS-2 will circle the globe 14 times a day 512 miles above Earth, providing forecasters the benefit of three polar-orbiting satellites operating simultaneously, joining its predecessors Suomi National Polar-orbiting Partnership (Suomi NPP) and NOAA-20. Following JPSS-2’s deployment, the LOFTID heat shield autonomously inflated and re-entered Earth’s atmosphere, splashing down about 500 miles off the coast of…

与杰瑞·C·埃利奥特一起庆祝美洲原住民遗产月

ByNASA中文 2022年11月11日

Jerry C. Elliott, a former NASA physicist and one of the first Native Americans hired at NASA’s Johnson Space Center, speaks during Native American Heritage Month event in 2017 at NASA’s Marshall Space Flight Center. He joined NASA in April 1966, as a Flight Mission Operations Engineer at NASA’s Mission Control Center and held technical and managerial positions with highly successful accomplishments in many fields including spacecraft systems, mission operations, astronaut crew equipment, scientific experiments and technical management. Elliott received the Presidential Medal of Freedom, the highest U.S. civilian honor, for duties as Retrofire Officer at NASA Mission Control Center during the aborted Apollo 13 space mission with the safe return of the flight crew.

宇航员杰西卡·沃特金斯和鲍勃·海恩斯在太空中研究农业

ByNASA中文 2022年11月10日

In this image from June 24, 2022, NASA astronauts Jessica Watkins and Bob Hines, part of NASA’s SpaceX Crew-4, work on the XROOTS space botany investigation, which used the International Space Station’s (ISS) Veggie facility to test soilless methods to grow plants. The space agricultural study could enable production of crops on a larger scale to sustain crews on future space explorations farther away from Earth and could enhance cultivation of plants in terrestrial settings such as greenhouses, contributing to better food security for people on Earth. Learn about the latest scientific research on the ISS.

NASA肯尼迪航天中心的血月月全食

ByNASA中文 2022年11月9日

This composite made from ten images shows the progression of the Moon during a total lunar eclipse above the Vehicle Assembly Building, Nov. 8, 2022, at NASA’s Kennedy Space Center in Florida. Visible trailing the Moon in this composite is Mars. For North America, the partial eclipse began at 4:09 a.m. EST, with totality beginning at 5:16 a.m. One feature of a total lunar eclipse is the Moon’s red hue during totality. The red color occurs because of the refraction, filtering, and scattering of light by Earth’s atmosphere. Image Credit: NASA/Joel Kowsky 2022年11月8日，在NASA位于佛罗里达州的肯尼迪航天中心，这张由十张照片合成的照片显示了月球在月全食期间的进程。在这张合成图中，可以看到尾随月球的火星。在北美，月偏食开始于美国东部时间凌晨4点09分，月全食开始于凌晨5点16分。月全食的一个特征是全食期间月亮的红色色调。红色的出现是因为地球大气层对光的折射、过滤和散射。影像来源：NASA/Joel Kowsky

NASA ABoVE团队研究融化的永久冻土，湖泊

ByNASA中文 2022年11月4日

Since 2015, scientists participating in NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) have been studying the impacts of climate change on Earth’s far northern regions and how those changes are intertwined. As our planet warms, permafrost—layers of soil that have stayed frozen for at least two years—thaws at an accelerating rate. This is changing the shape and vegetation of landscapes and, in some cases, creating new ponds and lakes that are also hotspots for greenhouse gas emissions. This thawing process is happening all over Alaska and northwestern Canada, which already has millions of lakes and ponds. Most of these lakes are hundreds or thousands of years old, meaning the microbes have run out of organic matter to decompose and the lakes are no longer releasing significant…

哈勃太空望远镜发现神秘的宇宙“钥匙孔”

ByNASA中文 2022年11月3日

This peculiar portrait from the NASA/ESA Hubble Space Telescope showcases NGC 1999, a reflection nebula in the constellation Orion. NGC 1999 is around 1,350 light-years from Earth and lies near the Orion Nebula, the closest region of massive star formation to Earth. NGC 1999 itself is a relic of recent star formation – it is composed of debris left over from the formation of a newborn star. Just like fog curling around a streetlamp, reflection nebulae like NGC 1999 shine by the light from an embedded source. In the case of NGC 1999, this source is the aforementioned newborn star V380 Orionis, which is visible at the center of this image. The most notable aspect of NGC 1999’s appearance, however, is the conspicuous hole in…

压力测试超级大黄蜂的翅膀

ByNASA中文 2022年11月2日

Teams at NASA’s Armstrong Flight Research Center in Edwards, California, recently completed stress testing on the Navy’s F/A-18E Super Hornet aircraft from the Naval Air Systems Command (NAVAIR) in Patuxent River, Maryland. The Super Hornet is seen here in a top view from March 2022 while in a wing loading test configuration at Armstrong. Understanding what stress, or strain, an aircraft can endure is critical to carrying out its intended mission. To better understand the aircraft’s capacity for strain, unique facilities can “load” the aircraft to specified stress points and document its performance. The test data resulted in the development of loads equations that calculate real-time loads experienced during flight testing, which can be compared to established design limits to ensure safety of flight and…
