In this image from April 2023, NASA’s Moonikin Campos, a manikin that flew on the Artemis I flight test beyond the Moon, enjoys a quiet moment during acceleration sled testing at Wright-Patterson Air Force Base in Ohio. Engineers put Moonikin Campos through acceleration sled testing to simulate contingency landings. Sled testing is a common method of testing restraint systems like automotive seats and seat belts to investigate their performance in collision situations. The tests are informing engineers’ understanding of what the experience of flying inside the agency’s Orion spacecraft will be like on crewed missions to the Moon beginning with Artemis II. During testing, the manikin wore the Orion Crew Survival System (OCSS) with a motion tracker on its forehead. Artemis astronauts will wear the…
为月球车测试新轮子
In this image from June 2023, an engineer watches a development model rover during a test for NASA’s Cooperative Autonomous Distributed Robotic Exploration (CADRE) technology demonstration in the Mars Yard at NASA’s Jet Propulsion Laboratory in Southern California. The team tested a new wheel design, surface navigation software, and mobility capabilities, among other aspects of the project. NASA is sending a trio of these miniature rovers to the Moon to see how well they can cooperate with one another without direct input from mission controllers back on Earth. About the size of a carry-on suitcase, each of the four-wheeled rovers will drive to find a sunbathing spot, where they’ll open their solar panels and charge up. Then they’ll spend the lunar daytime conducting experiments designed…
哈勃望远镜瞥见一个闪烁的星系团
The glittering, glitzy contents of the globular cluster NGC 6652 sparkle in this star-studded image from the NASA/ESA Hubble Space Telescope. The core of the cluster is suffused with the pale blue light of countless stars, and a handful of particularly bright foreground stars are adorned with crisscrossing diffraction spikes. NGC 6652 lies in our own Milky Way galaxy in the constellation Sagittarius, just under 30,000 light-years from Earth and only 6,500 light-years from the galactic center. Globular clusters are stable, tightly gravitationally bound clusters containing anywhere from tens of thousands to millions of stars. The intense gravitational attraction between closely packed stars in globular clusters is what gives these star-studded objects their regular, spherical shape. This image combines data from two of Hubble’s most…
从国际空间站看巴格达
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.

NASA的SpaceX Crew-7机组成员为他们的任务做准备
On April 28, 2023, the Crew-7 members (from left, Roscosmos cosmonaut Konstantin Borisov, European Space Agency astronaut Andreas Mogensen, NASA astronaut Jasmin Moghbeli, and Japan Aerospace Exploration Agency astronaut Satoshi Furukawa) took a moment to snap a photo atop an emergency egress vehicle at NASA’s Kennedy Space Center in Florida. Crew-7 will launch to the International Space Station on Monday, Aug. 21. will fly aboard the SpaceX Dragon spacecraft, named Endurance, which previously flew NASA’s SpaceX Crew-3 and Crew-5 missions to the space station. Follow NASA’s commercial crew blog for the latest information on Crew-7 flight readiness.

Terra航天器观察澳大利亚鲨鱼湾
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
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
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…
