NASA肯尼迪航天中心的血月月全食

ByNASA中文 2022年11月9日

This composite made from ten images shows the progression of the Moon during a total lunar eclipse above the Vehicle Assembly Building, Nov. 8, 2022, at NASA’s Kennedy Space Center in Florida. Visible trailing the Moon in this composite is Mars. For North America, the partial eclipse began at 4:09 a.m. EST, with totality beginning at 5:16 a.m. One feature of a total lunar eclipse is the Moon’s red hue during totality. The red color occurs because of the refraction, filtering, and scattering of light by Earth’s atmosphere.

ByNASA中文 2022年11月8日

NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard is illuminated by spotlights atop the mobile launcher at Launch Pad 39B as preparations for launch continued Sunday, Nov. 6, 2022, at NASA’s Kennedy Space Center in Florida. SLS and Orion arrived at the launch pad on Friday, Nov. 4, after a nearly nine-hour journey from the Vehicle Assembly Building. Artemis I is the first integrated test of our deep space exploration systems: the Orion spacecraft, SLS rocket, and supporting ground systems. Launch of the uncrewed flight test is targeted for Nov. 14 at 12:07 a.m. EST. See the full launch coverage schedule.

NASA宇航员妮可·A·曼的大拇指

ByNASA中文 2022年11月6日

Selected as an astronaut candidate in June 2013, Nicole A. Mann is the first Native American woman from NASA in space. In 2018, she was chosen as one of the nine astronauts to crew the first flight tests and missions of the Boeing CST-100 Starliner and SpaceX Crew Dragon. In her first spaceflight, she launched to the International Space Station as commander of NASA’s SpaceX Crew-5 mission aboard the SpaceX Crew Dragon spacecraft on Oct. 5, 2022. As mission commander, she will be responsible for all phases of flight, from launch to re-entry. Aboard the station, she serves as an Expedition 68 flight engineer.

NASA ABoVE团队研究融化的永久冻土，湖泊

ByNASA中文 2022年11月4日

Since 2015, scientists participating in NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) have been studying the impacts of climate change on Earth’s far northern regions and how those changes are intertwined. As our planet warms, permafrost—layers of soil that have stayed frozen for at least two years—thaws at an accelerating rate. This is changing the shape and vegetation of landscapes and, in some cases, creating new ponds and lakes that are also hotspots for greenhouse gas emissions. This thawing process is happening all over Alaska and northwestern Canada, which already has millions of lakes and ponds. Most of these lakes are hundreds or thousands of years old, meaning the microbes have run out of organic matter to decompose and the lakes are no longer releasing significant…

哈勃太空望远镜发现神秘的宇宙“钥匙孔”

ByNASA中文 2022年11月3日

This peculiar portrait from the NASA/ESA Hubble Space Telescope showcases NGC 1999, a reflection nebula in the constellation Orion. NGC 1999 is around 1,350 light-years from Earth and lies near the Orion Nebula, the closest region of massive star formation to Earth. NGC 1999 itself is a relic of recent star formation – it is composed of debris left over from the formation of a newborn star. Just like fog curling around a streetlamp, reflection nebulae like NGC 1999 shine by the light from an embedded source. In the case of NGC 1999, this source is the aforementioned newborn star V380 Orionis, which is visible at the center of this image. The most notable aspect of NGC 1999’s appearance, however, is the conspicuous hole in…

压力测试超级大黄蜂的翅膀

ByNASA中文 2022年11月2日

Teams at NASA’s Armstrong Flight Research Center in Edwards, California, recently completed stress testing on the Navy’s F/A-18E Super Hornet aircraft from the Naval Air Systems Command (NAVAIR) in Patuxent River, Maryland. The Super Hornet is seen here in a top view from March 2022 while in a wing loading test configuration at Armstrong. Understanding what stress, or strain, an aircraft can endure is critical to carrying out its intended mission. To better understand the aircraft’s capacity for strain, unique facilities can “load” the aircraft to specified stress points and document its performance. The test data resulted in the development of loads equations that calculate real-time loads experienced during flight testing, which can be compared to established design limits to ensure safety of flight and…

露齿葫芦装点银河

ByNASA中文 2022年11月1日

While observing the outer region of the Milky Way galaxy, our Spitzer Telescope captured this infrared image of a cloud of gas and dust that looks like the hollowed-out pumpkins we see every Halloween. Nicknamed the “Jack-o’-Lantern Nebula,” it was likely created by powerful outflows of radiation and particles from a massive O-type star, about 15 to 20 times heavier than the Sun. The data used to create this image was collected during Spitzer’s “cold mission,” which ran between 2004 and 2009. Image Credit: NASA/JPL-Caltech 在观测银河系外部区域时，NASA的斯皮策望远镜捕捉到了这张由气体和尘埃组成的云团的红外图像，它看起来就像我们每年万圣节都会看到的掏空的南瓜。它被称为“南瓜灯星云”，很可能是由一颗质量约为太阳15到20倍的大质量O型恒星的强大辐射和粒子外流形成。用于创建这张图像的数据是在2004年至2009年斯皮策的“冷任务”期间收集。影像来源：NASA/JPL-Caltech

韦伯揭示了创生之柱的新细节

ByNASA中文 2022年10月29日

Our James Webb Space Telescope has captured a new image of the famous Pillars of Creation—first imaged by the Hubble Space Telescope in 1995—that reveals new details about the region. The three-dimensional pillars look like majestic rock formations but are far more permeable. These columns are made up of cool interstellar gas and dust that sometimes appear semi-transparent in near-infrared light. Webb’s new view of the Pillars of Creation will help researchers revamp their models of star formation by identifying far more precise counts of newly formed stars, along with the quantities of gas and dust in the region. Over time, they will begin to build a clearer understanding of how stars form and burst out of these dusty clouds over millions of years. Download…

露西发现了地球和月球

ByNASA中文 2022年10月28日

On Oct. 13, 2022, NASA’s Lucy spacecraft captured this image of the Earth and the Moon from 890,000 miles (1.4 million km) away. The image was taken as part of an instrument calibration sequence as the spacecraft approached Earth for its first of three Earth gravity assists. These Earth flybys provide Lucy with the speed required to reach the Trojan asteroids — small bodies that orbit the Sun at the same distance as Jupiter. On its 12-year journey, Lucy will fly by a record-breaking number of asteroids and survey their diversity, looking for clues to better understand the formation of the solar system. The image was taken with Lucy’s Terminal Tracking Camera (T2CAM) system, a pair of identical cameras that are responsible for tracking the…

绘制整个夜空

ByNASA中文 2022年10月26日

This mosaic is composed of images covering the entire sky, taken by the Wide-field Infrared Survey Explorer (WISE) as part of WISE’s 2012 All-Sky Data Release. By observing the entire sky, WISE could search for faint objects, like distant galaxies, or survey groups of cosmic objects. Not visible to the human eye, infrared light is radiated by a plethora of cosmic objects, including cool, nearby stars and some of the most luminous galaxies in the universe. The WISE mission ended in 2011 after the onboard coolant – needed for some infrared observations – ran out, but the spacecraft and some of its infrared detectors were still functional. So, in 2013, NASA repurposed it to track asteroids and other near-Earth objects, or NEOs. Both the mission…
