Support teams onboard the SpaceX recovery ship MEGAN work to open the hatch of the SpaceX Dragon Endeavour spacecraft shortly after it landed in the Atlantic Ocean on Sept. 4, 2023, with NASA astronauts Stephen Bowen and Woody Hoburg, United Arab Emirates (UAE) astronaut Sultan Alneyadi, and Roscosmos cosmonaut Andrey Fedyaev aboard. Bowen, Hoburg, Alneyadi, and Fedyaev are returning after nearly six months in space aboard the International Space Station. This was the first spaceflight for all members except Bowen. During this expedition, Hoburg completed his first spacewalk, Alneyadi became the first UAE astronaut to conduct a spacewalk, and Bowen tied the record for most spacewalks by a U.S. astronaut, also held by Mike Lopez-Alegria, Bob Behnken, Peggy Whitson, and Chris Cassidy. Watch the crew…

哈勃望远镜发现嵌入银河系内部的闪光球状星团

This colorful image of the globular star cluster Terzan 12 is a spectacular example of how dust in space affects starlight coming from background objects. A globular star cluster is a conglomeration of stars, arranged in a spheroidal shape. Stars in globular clusters are bound together by gravity, with a higher concentration of stars towards the center. The Milky Way has about 150 ancient globular clusters at its outskirts. These clusters orbit around the galactic center, but far above and below the pancake-flat plane of our galaxy, like bees buzzing around a hive. The location of this globular cluster, deep in the Milky Way in the constellation Sagittarius, means that it is shrouded in gas and dust which absorb and alter the starlight emanating from…

A recovery team member takes part in field rehearsals in preparation for the retrieval of the sample return capsule from NASA’s OSIRIS-REx mission in this image from Aug. 29, 2023. The sample of rocks and dust, which the OSIRIS-REx spacecraft collected from the asteroid Bennu in Oct. 2020, will return to Earth on Sept. 24, safely landing at the Department of Defense’s Utah Test and Training Range. The sample will give generations of scientists a window into the time when the Sun and planets were forming about 4.5 billion years ago. Get a preview of what the asteroid sample recovery will look like and join us on Sept. 24 at 10 a.m. EDT for live coverage.

旅行者1号升空，迈向星际之旅

ByNASA中文

On Sept. 5, 1977, NASA’s Voyager 1 spacecraft lifts off atop its Titan/Centaur-6 launch vehicle from Launch Complex 41 at Cape Canaveral Air Force Station, now Cape Canaveral Space Force Station, in Florida. Voyager 1 and its twin, Voyager 2, were originally launched to conduct closeup studies of Jupiter and Saturn, Saturn’s rings, and the larger moons of the two planets. After completing these missions and more, Voyager 1 became the first spacecraft to reach interstellar space and is now the farthest human-made object from Earth. Scientists think it will reach the inner edge of the Oort Cloud in 300 years. Follow along with Voyager’s live mission status. 1977年9月5日，NASA的旅行者1号宇宙飞船在位于佛罗里达州卡纳维拉尔角空军基地（现在的卡纳维拉尔角太空基地）的41号发射场搭载泰坦/半人马-6运载火箭升空。 旅行者1号和它的孪生兄弟旅行者2号最初是为了对木星和土星、土星环以及这两颗行星中较大的卫星进行近距离研究。在完成这些任务和更多任务后，旅行者1号成为第一艘到达星际空间的航天器，现在是距离地球最远的人造物体。科学家们认为它将在300年后到达奥尔特云的内缘。 继续关注旅行者的实时任务状态。

As the International Space Station orbited 261 miles above Earth on Aug. 29, 2023, one of the space station’s external high-definition cameras captured Hurricane Idalia in the Gulf of Mexico. Hurricane Idalia made landfall over the Big Bend region of Florida on the morning of Aug. 30, 2023, as a category 3 storm. Winds measured 205 kilometers (125 miles) per hour as the storm reached land. Watch an animation of the storm’s wind field.

In this image from Sept. 5, 1983, Guion “Guy” Bluford checks out the sample pump on the continuous flow electrophoresis system (CFES) experiment in the middeck of the Earth-orbiting space shuttle Challenger. Forty years ago today, he launched from NASA’s Kennedy Space Center in Florida, becoming the first African American to fly in space. Bluford was a member of NASA’s “Thirty-Five New Guys” – the 1978 astronaut class, which had the first African American, the first Asian American, and the first women astronauts. During the STS-8 mission, the crew deployed the Indian National Satellite INSAT-1B, operated the Canadian-built Remote Manipulator System with the Payload Flight Test Article, operated the CFES, conducted medical measurements to understand biophysiological effects of spaceflight, and activated four “Getaway Special” canisters….

Rocky Garcia and Wesley James prepare a weather balloon to collect wind data at NASA’s Armstrong Flight Research Center in Edwards, California, on July 20, 2023. Researchers measured wind at altitudes below 2,000 feet using drones, sensors, weather balloons, and other technology during the Advanced Exploration of Reliable Operation at Low Altitudes: Meteorology, Simulation and Technology campaign. This information could fill knowledge gaps to resolve wind and weather unknowns that could hinder Advanced Air Mobility flights and to improve weather forecasts.

The galaxy ESO 300-16 looms over this image from the NASA/ESA Hubble Space Telescope. This galaxy, which lies 28.7 million light-years from Earth in the constellation Eridanus, is a ghostly assemblage of stars which resembles a sparkling cloud. Other distant galaxies and foreground stars complete this astronomical portrait, which was captured by the Advanced Camera for Surveys. This observation is one of a series which aims to get to know our galactic neighbors. Hubble has observed around three quarters of known galaxies within about 10 megaparsecs of Earth in enough detail to resolve their brightest stars and establish distances to these galaxies. A team of astronomers proposed using small gaps in Hubble’s observing schedule to acquaint ourselves with the remaining quarter of these nearby galaxies….

A Mercury-Redstone launch vehicle awaits test-firing in the Redstone Test Stand at NASA’s Marshall Space Flight Center in Huntsville, Alabama, in this photo from the late 1950s. Between 1953 and 1960, the rocket team at Redstone Arsenal in Huntsville performed hundreds of test firings on the Redstone rocket – over 200 on the Mercury-Redstone vehicle configuration alone. Through Project Mercury, the United States’ first human-in-space program, Mercury-Redstone provided NASA with an opportunity to understand performance aspects of the Mercury spacecraft, the effect of a weightless environment on astronauts, and launch and recovery operations at NASA’s Kennedy Space Center in Florida. Image Credit: NASA 在这张20世纪50年代末的照片中，一架水星-红石运载火箭正在阿拉巴马州亨茨维尔的NASA马歇尔航天飞行中心的红石测试台上等待试射。1953年至1960年间，位于亨茨维尔的红石兵工厂的火箭团队对红石火箭进行了数百次试射——仅水星-红石运载火箭配置就超过200次。 通过美国首个载人太空计划“水星计划”，水星-红石号为NASA提供了一个机会，了解水星飞船的性能、失重环境对宇航员的影响，以及佛罗里达州NASA肯尼迪航天中心的发射和回收操作。 影像来源：NASA
