Guinness World Records officially designated NASA’s Crawler Transporter 2 as the heaviest self-powered vehicle, weighing approximately 6.65 million pounds—equivalent to about 15 Statues of Liberty or 1,000 pickup trucks. During a March 29, 2023, ceremony at NASA’s Kennedy Space Center in Florida, Guinness World Records presented a certificate to teams with the Exploration Ground Systems Program and Kennedy leadership. Part of the crawler can be seen in the background of this photo taken the same day.

“People aren’t always recognized for who they are at work. “So giving a person time to actually talk about themselves, and be proud of what they do, and talk about how hard it might be to maintain their career with everything else going on — makes them feel valued and appreciated. And highlighting them in that way on the Faces of NASA page, makes that pride permanent. “I think I’m always seeking out projects that help people feel seen. And maybe that’s why I got so into photography initially. I struggle with that myself — feeling seen. And so to help other people feel seen is definitely an interest of mine that I keep coming back to.” — Aubrey Gemignani, Photo Archivist/Photographer, Co-founder of Faces…

A technician works on part of the Space Launch System (SLS) rocket’s core stage for Artemis II in this March 11, 2023, image. Artemis II is the first Artemis mission that will send four astronauts around the Moon and return them home. On March 17, technicians joined the engine section to the rest of the rocket stage; all five major structures of the SLS’s rocket core stage are now integrated. Next, teams will integrate the four RS-25 engines to the engine section to complete the stage. Image Credit: NASA/ Michael DeMocker 在这张2023年3月11日的图像中，一名技术人员正在为阿尔忒弥斯二号人物的太空发射系统（SLS）火箭的核心级工作。阿尔忒弥斯二号任务是第一个阿尔忒弥斯载人任务，它将送四名宇航员绕月飞行并将他们送回地球。 3月17日，技术人员将发动机部分连接到火箭级的其余部分；SLS火箭核心级的所有五个主要结构现在都集成在一起。接下来，各队将把四台RS-25发动机集成到发动机部分，以完成这一阶段。 影像来源：NASA/ Michael DeMocker

Stars leave streaks of light in concentric circles in this March 16, 2012, view from the International Space Station. To create this composite long exposure, NASA astronaut Don Pettit combined multiple 30-second exposures from a mounted camera on the space station into one image. The orbiting laboratory travels 5 miles per second, traveling around our planet every 90 minutes. Image Credit: NASA/Don Pettit 2012年3月16日，从国际空间站拍摄的照片中，恒星在同心圆上留下一道道光。为了制作这张合成的长时间曝光照片，NASA宇航员唐·佩蒂特将空间站上安装的相机拍摄的多张30秒曝光照片合成了一张照片。 轨道实验室每秒飞行5英里，每90分钟绕地球一周。 影像来源：NASA/Don Pettit

路易斯安那州的稻田

路易斯安那州的稻田

ByNASA中文

This Feb 3, 2023, enhanced-color image from Landsat 9 highlights a green and blue patchwork pattern in flooded rice fields in southwestern Louisiana. Raised levees used for water management form the grid pattern between the fields, which appear dark blue. As it flowed through several southern states over tens of thousands of years, the Mississippi River left a valuable layer of fertile soil in its wake. This low-lying floodplain and the flat coastal prairies of Louisiana and Texas are now home to most of the rice farms in the United States. In 2021, Arkansas, Louisiana, Mississippi, and Texas—collectively known as the Rice Belt—produced about 73 percent of all rice in the United States. Image Credit: NASA 这张2023年2月3日的增强彩色图像来自陆地卫星9号，突出显示了路易斯安那州西南部被洪水淹没的稻田中绿蓝相间的图案。用于水管理的加高的堤坝形成了田地之间的网格图案，呈现深蓝色。 数万年来，密西西比河流经美国南部几个州，留下了一层宝贵的沃土。这片低洼的洪泛平原以及路易斯安那州和德克萨斯州平坦的沿海大草原现在是美国大部分水稻农场的所在地。2021年，阿肯色州、路易斯安那州、密西西比州和德克萨斯州（统称为水稻带）的水稻产量约占美国总产量的73%。 影像来源：NASA

银河巨人土卫六和土星

Titan, Saturn’s largest moon, looks quite small in comparison to the giant planet behind it in this natural color view from the Cassini-Huygens spacecraft. This image from Aug. 29, 2012, also shows seasonal changes occurring on Saturn; as spring comes to the northern Saturnian hemisphere, the azure blue seen fades, while winter in the south adds a bluish hue. This phenomenon is likely due to shifts in the intensity of ultraviolet light and the haze it produces. Image Credit: NASA/JPL-Caltech/Space Science Institute 在卡西尼-惠更斯号宇宙飞船拍摄的这张自然色照片中，土星最大的卫星土卫六与身后的巨行星相比显得相当小。这张2012年8月29日拍摄的照片也显示了土星上发生的季节变化；随着土星北半球的春天到来，所见的湛蓝逐渐褪去，而南方的冬天则增添了一抹蓝色。这种现象可能是由于紫外线强度的变化及其产生的雾霾造成的。 影像来源：NASA/JPL-Caltech/Space Science Institute

Maat Mons, a volcano on Venus that has shown signs of a recent eruption, is in the black square near the planet’s equator in this annotated, computer-simulated global map of Venus’ surface. Scientists discovered direct geological evidence of recent volcanic activity on Venus by poring over archival radar images taken over 30 years ago by NASA’s Magellan mission. The images revealed a volcanic vent changing shape and increasing significantly in size in less than a year. Learn more about Maat Mons and NASA’s new mission to study Venus from surface to core.

An orbital sunrise reveals cloud tops above the Pacific Ocean northeast of New Zealand as the International Space Station orbited 260 miles above on Feb. 10, 2023. 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 has circumnavigated Earth tens of thousands of times. Image Credit: NASA 2023年2月10日，国际空间站在新西兰东北部的太平洋上空260英里轨道上运行，轨道上的日出显示出太平洋上空的云顶。由于轨道速度高（每小时17,500英里），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，空间站已经环绕地球数万次。 影像来源：NASA
