年度英仙座流星雨

年度英仙座流星雨

ByNASA中文

The Perseid meteors are an annual event many skywatchers look forward to, as they often produce lots of shooting stars to enjoy. The Perseids are debris remnants of Comet Swift-Tuttle, which takes 133 years to orbit the Sun once. The meteors often leave long “wakes” of light and color behind them as they streak through Earth’s atmosphere. They’re also known for their fireballs, which are larger explosions of light and color that can persist longer than an average meteor streak. This photo was taken Wednesday, Aug. 11, 2021, in Spruce Knob, West Virginia.

Aquanaut机器人在水下工作

Aquanaut机器人在水下工作

ByNASA中文

A team of roboticists from NASA’s Johnson Space Center in Houston have applied their expertise in making robots for deep space to designing a fully electric shape-changing submersible robot that will cut costs for maritime industries. Aquanaut, seen here during testing in the giant pool at Johnson’s Neutral Buoyancy Lab, opens its shell and turns its arms, claw hands, and various sensors to the job. NASA has a long history of transferring technology to the private sector. The agency’s Spinoff publication profiles NASA technologies that have transformed into commercial products and services, demonstrating the broader benefits of America’s investment in its space program. Spinoff is a publication of the Technology Transfer program in NASA’s Space Technology Mission Directorate (STMD). Learn more: NASA Space Robotics Dive…

哈勃望远镜俯瞰着太空的云景

This celestial cloudscape from the NASA/ESA Hubble Space Telescope captures the colorful region in the Orion Nebula surrounding the Herbig-Haro object HH 505. Herbig-Haro objects are luminous regions surrounding newborn stars that form when stellar winds or jets of gas spew from these infant stars creating shockwaves that collide with nearby gas and dust at high speeds. In the case of HH 505, these outflows originate from the star IX Ori, which lies on the outskirts of the Orion Nebula around 1,000 light-years from Earth. The outflows themselves are visible as gracefully curving structures at the top and bottom of this image. Their interaction with the large-scale flow of gas and dust from the core of the nebula distorts them into sinuous curves. Captured with…

Moonikin Campos, named after Arturo Campos, will be on Artemis I, an uncrewed flight test of the Orion spacecraft and Space Launch System rocket as an integrated system ahead of crewed flights to the Moon. Moonikin Campos, along with two phantom manikins, Helga and Zohar, will allow us to measure radiation, acceleration, and vibration data throughout the mission; the information gathered from these human body replicas will inform future crewed missions. Image Credit: NASA/Ben Smegelsky 以阿图罗·坎波斯命名的Moonikin Campos，将在载人登月飞行之前，作为一个集成系统，在猎户座飞船和太空发射系统火箭的阿耳忒弥斯1号任务上进行无人飞行测试。Moonikin Campos，以及两个幻影假人，Helga和Zohar，将允许我们在整个任务期间测量辐射、加速度和振动数据；从这些人体复制品中收集的信息将为未来的载人任务提供信息。 影像来源：NASA/Ben Smegelsky

In this picture from 2016, our Super Guppy, a specialized aircraft with a unique hinged nose, lands at Moffett Field at NASA Ames. Boasting an immense cargo area that is 25 feet in diameter and 111 feet long, the Super Guppy can carry items that are virtually impossible to fit inside other cargo aircraft. In early August 2022, it arrived at Marshall with a structural test article of part of NASA’s mega Moon rocket. The hardware was used in test campaigns at Marshall and NASA’s Kennedy Space Center in Florida and was returned to Marshall for storage.

This Moon-mosaic is comprised of 1,231 images taken by the Lunar Reconnaissance Orbiter’s (LRO) Narrow-Angle Camera (NAC) in the summer of 2018. The LRO team chose each tile from over 10,000 of the highest quality LROC NAC frames by searching for the best match of brightness and gradient (the direction and size of the brightness change across the frame). Since LRO’s launch in 2009, the camera team has published over one million gigabytes of image data, all of which are available to the public. In anticipation of the upcoming Artemis I mission to the Moon, NASA is asking the public to share all of your Moon-inspired content — including but not limited to your Moon photographs, your Moon music, and your Moon nail art —…

Today marks 10 years since the Curiosity rover landed on Mars. Since August 2012, Curiosity has been exploring 3-mile-high Mt. Sharp in Gale Crater. The rover has climbed more than 2,000 feet (612 meters), reaching progressively younger rocks that serve as a record on how Mars has evolved from a wet, habitable planet to a cold desert environment. The photogenic rover created this self-portrait at Gale Crater on Sol 2082 (June 15, 2018) using the Mars Hand Lens Imager, or MAHLI. See more of Curiosity’s accomplishments and download a commemorative poster.

Like distant galaxies amid clouds of interstellar dust, chunks of sea ice drift through graceful swirls of grease ice in the frigid waters of Foxe Basin near Baffin Island in the Canadian Arctic. Sea ice often begins as grease ice, a soupy slick of tiny ice crystals on the ocean’s surface. As the temperature drops, grease ice thickens and coalesces into slabs of more solid ice. This image was acquired 20 years ago today by the Landsat 7 satellite. To learn more about the NASA/USGS Landsat Program, visit https://landsat.gsfc.nasa.gov. Image Credit: USGS/NASA/Landsat 7 在加拿大北极巴芬岛附近的福克斯盆地寒冷的海水中，大块的海冰像星际尘埃云中的遥远星系一样，漂浮在优雅的油脂状冰漩涡中。海冰通常以油脂状冰开始，油脂状冰是海洋表面的一种由微小冰晶组成的粘性滑面。随着温度下降，油脂状冰变厚并聚结成更坚固的冰块。 这幅图像是20年前的今天由陆地资源卫星7号卫星拍摄的。如欲了解有关NASA/USG陆地资源卫星计划的更多信息，请访问https://landsat.gsfc.nasa.gov. 影像来源：USGS/NASA/Landsat 7

With wildflowers surrounding the view, NASA’s Space Launch System (SLS) Moon rocket – carried atop the Crawler-Transporter 2 – arrives at Launch Pad 39B at the agency’s Kennedy Space Center in Florida on June 6, 2022. The first in an increasingly complex series of missions, Artemis I will test the SLS rocket and Orion spacecraft as an integrated system prior to crewed flights to the Moon. Through Artemis, NASA will land the first woman and first person of color on the lunar surface, paving the way for a long-term lunar presence and using the Moon as a steppingstone before venturing to Mars.

NASA celebrates the life of Nichelle Nichols, Star Trek actor, trailblazer, and role model, who symbolized to so many what was possible. She partnered with us to recruit some of the first women and minority astronauts, and inspired generations to reach for the stars. In this photo from February 2012, Nichols was a featured guest speaker in the Building 8 auditorium at NASA’s Goddard Space Flight Center in Greenbelt, Md. at a special event commemorating of the life and legacy of Dr. Martin Luther King, Jr. Read more: Nichelle Nichols Helped NASA Break Boundaries on Earth and in Space Image credit: NASA/Goddard Space Flight Center/Pat Izzo NASA纪念切尔·尼科尔斯的一生，她是《星际迷航》的演员、开拓者和榜样，她向许多人展示了一切可能。她与我们合作,招募了第一批女性和少数族裔宇航员，并激励了几代人去探索星空。 在这张2012年2月的照片中，尼科尔斯在马里兰州格林贝尔特的美国宇航局戈达德航天飞行中心8号楼礼堂担任特邀演讲人，出席纪念小马丁·路德·金博士生平和遗产的特别活动。 阅读更多：尼切尔·尼科尔斯帮助NASA打破了地球和太空的界限 图片来源：NASA/Goddard Space Flight Center/Pat Izzo
