戴安娜·特鲁希略激发学生的好奇心

ByNASA中文 2023年3月16日

Elementary school students eagerly raise their hands as Diana Trujillo, technical group supervisor for sequence planning and execution and tactical mission lead for the Mars Perseverance rover, speaks to them on March 13, 2023. Born and raised in Colombia, Trujillo immigrated to the U.S. at the age of 17 to pursue her dream of working for NASA. She has held several roles for NASA and JPL, including Mars Curiosity rover mission lead, deputy project system engineer, and deputy team chief of engineering operations on Curiosity. Trujillo has also been active in sharing the excitement and opportunities of STEM with the public. She co-created and hosted #JuntosPerseveramos, NASA’s first Spanish-language live broadcast of a planetary landing, for Perseverance’s arrival on Mars, which attracted millions of viewers…

Crew-5夜间溅落

ByNASA中文 2023年3月14日2023年3月14日

The SpaceX Dragon Endurance spacecraft is seen as it lands with Crew-5 mission members aboard on Saturday, March 11, 2023. The crew returned in a parachute-assisted splashdown at 9:02 p.m. EST. During the 156.5 days they spent aboard the International Space Station as part of Expedition 68, Crew-5 participated in several spacewalks to prepare the space station for solar arrays and conducted various experiments, including growing plants without soil and studying radiation exposure.

一缕阳光

ByNASA中文 2023年3月10日2023年3月10日

The Moon is seen passing in front of the Sun during a solar eclipse from Ross Lake, Northern Cascades National Park, Washington on Aug. 21, 2017. A total solar eclipse swept across a narrow portion of the contiguous United States from Lincoln Beach, Oregon to Charleston, South Carolina. A partial solar eclipse was visible across the entire North American continent along with parts of South America, Africa, and Europe. This was the first total eclipse to span the U.S. since 1918, and with scientific advancements, presented a perfect opportunity to shed light on phenomena such as solar flares and coronal mass ejections. See when and where in the United States solar eclipses will be visible in 2023 and 2024. Image Credit: NASA/Bill Ingalls 2017年8月21日，在华盛顿州喀斯喀特国家公园北部的罗斯湖发生日食时，月亮从太阳前面经过。一次日全食席卷了美国从俄勒冈州林肯海滩到南卡罗来纳州查尔斯顿的一小部分地区。整个北美大陆以及南美、非洲和欧洲的部分地区都可以看到日偏食。这是自1918年以来第一次横跨美国的日全食，随着科学的进步，这为阐明太阳耀斑和日冕物质抛射等现象提供了绝佳的机会。…

艾琳·柯林斯，发现号飞行员

ByNASA中文 2023年3月9日

Former astronaut Eileen Collins sits at the pilot’s station aboard space shuttle Discovery during a hotfiring procedure on Feb. 2, 1995. Selected by NASA in January 1990, Collins became the first woman pilot of a Space Shuttle and the first woman to command a shuttle mission. Over four missions—STS-63 Discovery, STS-84 Atlantis, STS-93 Columbia, and STS-114 Discovery—she logged over 537 hours in space. Highlights of her missions include the Chandra X-Ray Observatory deployment, scientific experiments, and evaluation of new flight safety procedures. Learn more about women astronauts and their significant accomplishments to spaceflight.

哑铃星云发出光秀

ByNASA中文 2023年3月8日

Infrared light surges out from the Dumbbell Nebula, also known as Messier 27, in this Aug. 10, 2011, image from NASA’s Spitzer Space Telescope. This nebula was discovered in 1764 by Charles Messier. It was the first in a class of objects, now known as planetary nebulae, to make it into Messier’s catalog of astronomical objects. Planetary nebulae, historically named for their resemblance to gas-giant planets, are now known to be the remains of stars that once looked a lot like our Sun. Image Credit: NASA/JPL-Caltech/Harvard-Smithsonian CfA 2011年8月10日，NASA斯皮策太空望远镜拍摄的这张照片中显示了哑铃状星云（也被称为梅西耶27）发出的红外光。这个星云是查尔斯·梅西耶于1764年发现。这是目前被称为行星状星云的一类天体中第一个将其纳入星云星团表的天体。行星状星云，历史上因其与气态巨行星相似而得名，现在被认为是曾经看起来非常像我们太阳的恒星的残骸。影像来源：NASA/JPL-Caltech/Harvard-Smithsonian CfA

从空间站拍摄到的飓风弗莱迪

ByNASA中文 2023年3月7日

Cyclone Freddy is pictured northeast of the island nation of Mauritius from the International Space Station as it orbited 267 miles above the Indian Ocean on Feb. 20, 2023. On the space station are two NASA-built weather instruments, the Compact Ocean Wind Vector Radiometer (COWVR) and the Temporal Experiment for Storms and Tropical Systems (TEMPEST), that track tropical cyclones like Freddy. Launched in late 2021 to the space station, COWVR measures the speed and direction of wind at the ocean surface, and TEMPEST provides atmospheric water vapor measurements. Image Credit: NASA/Nicole Mann 2023年2月20日，国际空间站在印度洋毛里求斯岛国东北部267英里的上空，拍摄到了飓风弗雷迪的照片。空间站上有两个NASA制造的气象仪器，即紧凑型海洋风矢量辐射计（COWVR）和风暴和热带系统时间实验（TEMPEST），它们追踪像弗雷迪这样的热带气旋。COWVR于2021晚些时候发射到空间站，测量海面风速和风向，TEMPEST提供大气水汽测量。图片来源: NASA/Nicole Mann
