从国际空间站看巴格达

ByNASA中文 2023年8月4日

United Arab Emirates astronaut Sultan Alneyadi captured this image of the city lights of Baghdad, Iraq, and the Tigris River on July 18, 2023, as the International Space Station orbited 261 miles above the Middle Eastern nation. Since the station became operational in November 2000, crew members have produced hundreds of thousands of images of the land, oceans, and atmosphere of Earth, and even of the Moon through Crew Earth Observations. Their photographs of Earth record how the planet changes over time due to human activity and natural events.

Terra航天器观察澳大利亚鲨鱼湾

ByNASA中文 2023年8月2日

Hamelin Pool Marine Nature Reserve, seen here in an image from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra spacecraft on Dec. 30, 2010, is a special site. Located in the Shark Bay World Heritage Site in Western Australia, it is one of the very few places in the world where we can find living stromatolites—the first living examples of structures built by cyanobacteria. Photosynthetic cyanobacteria are thought to have changed the course of life’s evolution on Earth by playing an important role in the oxygenation of Earth’s atmosphere roughly 2.3 billion years ago. Also, NASA and other federal agencies monitor levels of cyanobacteria, as toxic levels of the blue-green algae can have negative effects on health. ASTER is one of…

为猎户座的第二次返回做准备

ByNASA中文 2023年8月1日

The Crew Module Test Article (CMTA), a full-scale mockup of NASA’s Orion spacecraft, is seen in the waters of the Pacific Ocean on July 26, 2023, during the first in a series of tests conducted by NASA and the Department of Defense to demonstrate and evaluate the processes, procedures, and hardware for recovery operations for crewed Artemis missions. This test is the first specifically in support of the Artemis II mission and allowed the team to practice what it will be like to recover astronauts and get them back to the recovery ship safely. Image Credit: NASA/Frank Michaux 在NASA正在进行的回收测试10 (URT-10)期间，机组人员模块测试文章(CMTA)出现在太平洋水域。CMTA是猎户座飞船的全尺寸模型，由NASA及其国防部合作伙伴使用它来练习阿尔忒弥斯载人任务的回收程序。URT-10是第一次专门支持阿尔忒弥斯2号任务的测试，让团队练习如何回收宇航员，并将他们安全地带回回收船。影像来源：NASA/Frank Michaux

哈勃望远镜窥视宁静星系

ByNASA中文 2023年7月29日

The tranquil spiral galaxy UGC 12295 basks leisurely in this image from the NASA/ESA Hubble Space Telescope. This galaxy lies around 192 million light-years away in the constellation Pisces and is almost face-on when viewed from Earth, displaying a bright central bar and tightly wound spiral arms. Despite its tranquil appearance, UGC 12295 played host to a catastrophically violent explosion – a supernova – detected in 2015. Supernovae are the explosive deaths of massive stars and are responsible for forging many of the elements found here on Earth. Two different teams of astronomers used Hubble’s Wide Field Camera 3 to observe UGC 12295 and sift through the wreckage of this vast stellar explosion. The first team examined the supernova’s detritus to better understand the evolution…

Woody Hoburg took this photo of Laguna Verde’s inviting waters as the International Space Station orbited 264 miles (425 km) over South America on July 7, 2023. Laguna Verde, which has an altitude of over 14,000 feet (4,300 meters), is located in the Andes mountains of Chile. Even taller landmarks surround the high-altitude lake, including Ojos del Salado—the tallest peak in Chile and the highest volcano on Earth. See more photos of Earth taken by astronauts on the space station.

GE Aerospace and magniX have revealed the paint schemes of the hybrid electric aircraft they will fly as part of NASA’s Electrified Powertrain Flight Demonstration (EFPD) project. Under EPFD, GE Aerospace is developing a megawatt-class hybrid electric powertrain for ground and flight tests in the middle of this decade. Boeing and its subsidiary Aurora Flight Sciences are partnering with GE Aerospace to support the flight tests using a modified Saab 340B aircraft. The flight test campaigns will be based out of Aurora Flight Sciences’ facilities, including in Manassas, Virginia. For its demonstration, magniX is partnering with AeroTEC and Air Tindi to test its hybrid powertrain installed on a modified DeHavilland “Dash 7” aircraft. The flight test campaigns will be based out of the AeroTEC Flight…

Elaborate Passiflora incarnata, or purple passionflower, sit pretty in a field at NASA’s Kennedy Space Center in Florida on June 13, 2023. Kennedy and the National Merritt Island Wildlife Refuge share a border and are home to more than 330 native and migratory bird species, 65 amphibian and reptile species, and more than 1,000 different types of plants including the purple passionflower. Kennedy is responsible for more protected species than any other federal property in the continental United States, and there are diverse and varied efforts to protect and preserve ecological systems at the center while simultaneously supporting the NASA mission.

OSIRIS-REx任务在犹他沙漠彩排

ByNASA中文 2023年7月24日

In preparation for the retrieval of the sample return capsule from NASA’s OSIRIS-REx mission, recovery teams tour the projected landing ellipse in the Utah desert on July 17, 2023. The sample, collected from the asteroid Bennu in October 2020 by NASA’s OSIRIS-REx spacecraft, will return to Earth on September 24, 2023. The rocks and dust collected from the asteroid will offer scientists a window into the time when the Sun and planets were forming about 4.5 billion years ago. The team has rehearsed portions of the recovery operation many times this year, but this was the most realistic rehearsal yet. See highlights from the rehearsal on the OSIRIS-REx blog. Image Credit: NASA/Keegan Barber 2023年7月17日，为了准备从NASA的OSIRIS-REx任务中取回样本回收舱，回收团队在犹他州沙漠的预计着陆椭圆中巡视。该样本于2020年10月由NASA的OSIRIS-REx航天器从小行星贝努上采集，将于2023年9月24日返回地球。从小行星上收集到的岩石和尘埃将为科学家们提供一扇了解大约45亿年前太阳和行星形成的窗口。该团队今年已经多次排练了部分恢复操作，但这是迄今为止最真实的一次排练。在OSIRIS-REx博客上查看彩排集锦。影像来源：NASA/Keegan Barber
