国际空间站访问南帕德雷岛

国际空间站访问南帕德雷岛

ByNASA中文

While the International Space Station orbited over the Gulf of Mexico on Sept. 19, 2022, NASA astronaut Bob Hines captured this image of South Padre Island, a barrier island along the coast of Texas. The island is part of the greater Padre Island, the longest barrier island in the world, which spans a length of 113 miles (182 kilometers). Barrier islands along the Gulf and East coasts of North America play a critical role protecting the mainland from the damaging effects of storms. They bear the brunt of large storm surges and reduce flooding on the mainland.

An American bald eagle occupies a nest near Kennedy Parkway North at NASA’s Kennedy Space Center on Feb. 8, 2023. Each year, eagles take up winter residence at the Florida spaceport, breeding and raising a new generation. The center shares a boundary with the Merritt Island National Wildlife Refuge, home to more than 1,500 species of plants and animals, and 15 federally listed species.

Japan Aerospace Exploration Agency astronaut Koichi Wakata is pictured in his Extravehicular Mobility Unit, or spacesuit, during his spacewalk on Feb. 2, 2023. He and NASA astronaut Nicole Mann, who took this photo, installed a modification kit on the International Space Station’s starboard truss structure that will enable the future installation of the orbiting lab’s next roll-out solar array. Four solar arrays, or iROSAs, have been installed so far, and two additional arrays will be mounted to the installed platforms during future spacewalks.

A snapshot of the Tarantula Nebula (also known as 30 Doradus) is featured in this image from the NASA/ESA Hubble Space Telescope. The Tarantula Nebula is a large star-forming region of ionized hydrogen gas that lies 161,000 light-years from Earth in the Large Magellanic Cloud, and its turbulent clouds of gas and dust appear to swirl between the region’s bright, newly formed stars. The Tarantula Nebula is a familiar site for Hubble. It is the brightest star-forming region in our galactic neighborhood and home to the hottest, most massive stars known. This makes it a perfect natural laboratory in which to test out theories of star formation and evolution, and Hubble has a rich variety of images of this region. The NASA/ESA/CSA James Webb Space…

Officials from NASA, the Indian Space Research Organisation (ISRO), and the Indian Embassy visit a clean room at NASA’s Jet Propulsion Laboratory on Feb. 3, 2023, to view the scientific instrument payload for the NASA-ISRO Synthetic Aperture Radar (NISAR) mission. The NISAR mission—a joint effort between NASA and ISRO—will measure changes to Earth’s land ice surfaces down to fractions of an inch. Data collected by this satellite will help researchers monitor a wide range of changes critical to life on Earth in unprecedented detail. Learn more about the visit and what NISAR will do. Image Credit: NASA/JPL-Caltech 2023年2月3日，NASA、印度太空研究组织（ISRO）和印度大使馆的官员参观了NASA喷气推进实验室的一间洁净室，以查看NASA-ISRO合成孔径雷达（NISAR）任务的科学仪器有效载荷。 NASA和ISRO联合开展的NISAR任务将测量地球陆地冰层表面的变化，精确到一英寸。这颗卫星收集的数据将帮助研究人员以前所未有的细节监测对地球生命至关重要的广泛变化。 了解关于这次访问和NISAR将做什么的更多信息。 图片来源: NASA/JPL-Caltech

This Jan. 10, 2013, composite image of the giant barred spiral galaxy NGC 6872 combines visible light images from the European Southern Observatory’s Very Large Telescope with far-ultraviolet data from NASA’s Galaxy Evolution Explorer (GALEX) and infrared data acquired by NASA’s Spitzer Space Telescope. NGC 6872 is 522,000 light-years across, making it more than five times the size of the Milky Way galaxy; in 2013, astronomers from the United States, Chile, and Brazil found it to be the largest-known spiral galaxy, based on archival data from GALEX. Image Credit: NASA/ESO/JPL-Caltech/DSS 2013年1月10日，这张巨型棒状螺旋星系NGC 6872的合成图像结合了欧洲南方天文台超大型望远镜的可见光图像、NASA星系演化探测器（GALEX）的远紫外数据和NASA斯皮策太空望远镜的红外数据。NG C6872的直径为522,000光年，是银河系的五倍多；2013年，根据GALEX的档案数据，美国、智利和巴西的天文学家发现它是已知最大的螺旋星系。 影像来源：NASA/ESO/JPL-Caltech/DSS

In this photo from Oct. 14, 2008, a great blue heron stands watch among a pond of water lilies on NASA’s Kennedy Space Center. It is one of 310 species of birds that inhabit the National Merritt Island Wildlife Refuge, which shares a boundary with Kennedy. The marshes and open water of the refuge also provide wintering areas for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans, and other species of marsh and shore birds. Kennedy is responsible for more protected species than any other federal property in the continental United States.

Chile’s Villarrica volcano emits steam and other volcanic gases in this photo taken from the International Space Station on Jan. 17, 2023. The gases come from a series of minor explosions—called Strombolian eruptions—that have been ongoing at Villarrica since October 2022. Located along Chile’s southern Andes, Villarrica is one of the most active and dangerous volcanoes in South America; it typically erupts every three to six years. Image Credit: NASA 2023年1月17日，在国际空间站拍摄的这张照片中，智利的维拉里卡火山喷出蒸汽和其他火山气体。这些气体来自一系列被称为斯特龙博利亚火山爆发的小型爆炸，自2022年10月以来一直在比利亚里卡持续发生。 比利亚里卡火山位于智利安第斯山脉南部，是南美洲最活跃、最危险的火山之一；它通常每三到六年爆发一次。 影像来源：NASA

The bright variable star V 372 Orionis takes center stage in this image from the NASA/ESA Hubble Space Telescope, which has also captured a smaller companion star in the upper left of this image. Both stars lie in the Orion Nebula, a colossal region of star formation roughly 1,450 light-years from Earth. V 372 Orionis is a particular type of variable star known as an Orion Variable. These young stars experience some tempestuous moods and growing pains, which are visible to astronomers as irregular variations in luminosity. Orion Variables are often associated with diffuse nebulae, and V 372 Orionis is no exception; the patchy gas and dust of the Orion Nebula pervade this scene. This image overlays data from two of Hubble’s instruments. Data from…
