54年前：阿波罗11号宇航员在月球上行走

ByNASA中文 2023年7月21日

Astronaut Buzz Aldrin, lunar module pilot of Apollo 11, the first lunar landing mission, poses for a photograph beside the deployed United States flag during a walk on the lunar surface. The lunar module is on the left, and the footprints of the astronauts are clearly visible in the soil of the moon. Astronaut Neil A. Armstrong, mission commander, took this picture with a 70mm Hasselblad lunar surface camera.

星城卫星发射升空

ByNASA中文 2023年7月20日2023年7月20日

On July 17, 2023, NASA’s four Starling CubeSats successfully deployed after having launched aboard Rocket Lab’s Electron rocket, shown in this image. NASA sent the team of four six-unit (6U)-sized CubeSats into orbit around Earth to see if they’re able to cooperate on their own, without real-time updates from mission control. The four CubeSats will fly in two different formations to test several technologies paving the way towards a future where swarms of satellites can cooperate to do science in deep space. The Starling mission will last at least six months, positioning the spacecraft about 355 miles above Earth and spaced about 40 miles apart. See more photos from the launch on Flickr and get the latest on Starling on the Small Satellite Missions blog….

北非上空云层密布

ByNASA中文 2023年7月19日

As the International Space Station orbited 259 miles above North Africa, swirls of clouds covered the sky. To the bottom right of the image, one of the station’s roll-out solar arrays peeks through. Astronauts aboard the space station see 16 sunrises and sunsets per day due to their high orbital velocity—17,500 miles per hour. In the more than 20 years that people have been living aboard the station, it has circumnavigated Earth tens of thousands of times. Image Credit: NASA 当国际空间站在北非上空259英里的轨道上运行时，天空布满了漩涡状的云。在图像的右下方，空间站的太阳能电池阵列隐约可见。由于轨道速度很高(17500英里/小时)，空间站上的宇航员每天能看到16次日出和日落。在人们居住在空间站的20多年里，它已经绕地球飞行了数万次。影像来源：NASA

阿尔忒弥斯机组人员的全电动载具

ByNASA中文 2023年7月18日

One of three specially designed, fully electric, environmentally friendly crew transportation vehicles for Artemis missions sits at Launch Pad 39B at NASA’s Kennedy Space Center in Florida on July 11, 2023. These zero-emission vehicles, manufactured by Canoo Technologies Inc., will take Artemis crews on the final Earth-bound leg of their journey to the Moon before boarding their rocket and spacecraft. The new vehicles are customized to accommodate NASA’s unique specifications for Artemis missions while also paying homage to the legacy of the agency’s human spaceflight and space exploration efforts. Many aspects of the design, from the interior and exterior markings to the color of the vehicles to the wheel wells, were chosen by a creative team that included the Artemis launch director and representatives from…

为未来NASA的3个阿尔忒弥斯任务猎户座载人舱欢呼

ByNASA中文 2023年7月15日

The Orion spacecraft for NASA’s crewed Artemis II (right), Artemis III (left) and Artemis IV (center) missions are stationed next to each other inside the high bay of the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on June 22, 2023. Each capsule is in a different stage of production as technicians and engineers prepare the spacecraft to carry astronauts to and around the Moon on their upcoming flights. Technicians recently installed the heat shield on the Artemis II crew module, and teams are preparing to conduct acoustic testing later this summer. Once complete, the crew module will be joined with its service module in preparation to fly four astronauts around the Moon. The Artemis III crew module, which will…

巴西的新月形沙丘

ByNASA中文 2023年7月15日

Former NASA astronaut Jack Fischer captured this photograph of Lagoa dos Barros and crescent-shaped barchan dunes on the Atlantic coastline of southern Brazil on July 9, 2017, while aboard the International Space Station. Barchan dunes are sand dunes that form in areas with one wind direction and little vegetation. In this case, fierce winds from the Western Atlantic sculpt the sand along the coast into distinctive crescent shapes. The tips of barchan dunes point downwind, showing the prevailing wind direction. These fragile formations act as barriers keeping the wind and waves from penetrating inland, blunting the effect of storms and minimizing coastal erosion. See more photos of Earth taken from space. Image Credit: NASA/ Jack Fischer 2017年7月9日，前NASA宇航员杰克·菲舍尔在国际空间站上拍摄了这张巴西南部大西洋海岸线上的拉戈亚·多斯·巴罗斯和新月形沙丘的照片。新月形沙丘是在单一风向和植被稀少的地区形成的沙丘。在这种情况下，来自西大西洋的强风将海岸的沙子塑造成独特的新月形。新月形沙丘的尖端指向下风，表明盛行风向。这些脆弱的地层充当屏障，阻止风和海浪穿透到内陆，减弱风暴的影响，最大限度地减少海岸侵蚀。查看更多从太空拍摄的地球照片。图片来源: NASA/ Jack Fischer

韦伯的第一张深场影像

ByNASA中文 2023年7月13日2023年7月13日

President Joe Biden unveiled this image of the galaxy cluster SMACS 0723 during a White House event on July 11, 2022. One year later, the James Webb Space Telescope has changed the way we see the universe. From new views of old subjects to discoveries on the chemical composition of exoplanets, Webb has helped us gather clues about the origins of our own solar system and beyond. To celebrate the completion of a successful first year, NASA has released Webb’s image of a small star-forming region in the Rho Ophiuchi cloud complex. Learn more about SMACS 0723 and how Webb captured this image. Image Credit: NASA, ESA, CSA, and STScI 2022年7月11日，美国总统乔·拜登在白宫的一次活动中发布了这张星系团SMACS 0723的照片。一年后，詹姆斯·韦伯太空望远镜改变了我们观察宇宙的方式。从对旧主题的新观测，到对系外行星化学成分的发现，韦伯帮助我们收集了有关太阳系起源的线索。为了庆祝第一年观测的成功完成，NASA发布了韦伯在蛇夫座星云复合体中一个小恒星形成区域的图像。了解更多关于SMACS 0723的信息，以及韦伯如何拍摄到这张照片。图片来源: NASA, ESA, CSA和STScI

A bobcat surveys the landscape at NASA’s Armstrong Flight Research Center in Edwards, California in this March 11, 2021, image. The spotted feline makes its home on the more than 300,000 acres of Mojave Desert surrounding the NASA facility housed at Edwards Air Force Base. Named in honor of Neil A. Armstrong, a former research test pilot at the center and the first man to step on the moon, Armstrong is NASA’s primary center for high-risk, atmospheric flight research and test projects.

新视野号的红外图像

ByNASA中文 2023年7月11日

NASA’s New Horizons spacecraft captured this high-resolution enhanced color view of Charon, Pluto’s largest moon, just before closest approach on July 14, 2015. The image combines blue, red, and infrared images taken by the spacecraft’s Ralph/Multispectral Visual Imaging Camera (MVIC); the colors are processed to best highlight the variation of surface properties across Charon. New Horizons conducted a six-month-long reconnaissance flyby study of Pluto and its moons in summer 2015, helping us understand worlds at the edge of our solar system, then venturing deeper into the distant, mysterious Kuiper Belt – a relic of solar system formation. The spacecraft is now more than 5 billion miles from Earth and uses machine-learning AI software to make searches beyond the Kuiper Belt much faster and more productive….
