绿湖的蓝绿色水域

ByNASA中文 2023年7月27日

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.

NASA，行业合作伙伴公布混合动力电动飞机涂装方案

ByNASA中文 2023年7月26日

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…

一朵野花的特写

ByNASA中文 2023年7月25日

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

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
