为毅力号火星漫游车在火星上收集样本做准备

为毅力号火星漫游车在火星上收集样本做准备

The samples Apollo 11 brought back to Earth from the Moon were humanity’s first from another celestial body. NASA’s upcoming Mars 2020 Perseverance rover mission will collect the first samples from another planet (the red one) for return to Earth by subsequent missions. In place of astronauts, the Perseverance rover will rely on the most complex, capable and cleanest mechanism ever to be sent into space, the Sample Caching System. In this image taken on May 20, 2020 at the Kennedy Space Center, engineers and technicians insert 39 sample tubes into the belly of the rover. Each tube is sheathed in a gold-colored cylindrical enclosure to protect it from contamination. Perseverance rover will carry 43 sample tubes to the Red Planet’s Jezero Crater. Image Credit:…

冰川融化加速了区域淡水的消耗

冰川融化加速了区域淡水的消耗

A small glacier in the Arctic region of Norwegian archipelago Svalbard, as photographed by NASA’s Airborne Tropical Tropopause Experiment (ATTREX). This is one of the seven regions where ice loss is accelerating, causing the depletion of freshwater resources. Seven of the regions that dominate global ice mass losses are melting at an accelerated rate, a new study shows, and the quickened melt rate is depleting freshwater resources that millions of people depend on. The impact of melting ice in Greenland and Antarctica on the world’s oceans is well documented. But the largest contributors to sea level rise in the 20th century were melting ice caps and glaciers located in seven other regions: Alaska, the Canadian Arctic Archipelago, the Southern Andes, High Mountain Asia, the Russian…

Demo-2:载入史册

On Saturday, May 30, 2020, a SpaceX Falcon 9 rocket carrying the company’s Crew Dragon spacecraft launched on NASA’s SpaceX Demo-2 mission to the International Space Station and made its way into the history books. The Demo-2 mission is the first launch with astronauts of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. The test flight serves as an end-to-end demonstration of SpaceX’s crew transportation system. Behnken and Hurley launched at 3:22 p.m. EDT on Saturday, May 30, from Launch Complex 39A at the Kennedy Space Center. A new era of human spaceflight is set to begin as American astronauts once again launch on an American rocket from American soil to…

哈勃望远镜拍到了灿烂的星星织锦

哈勃望远镜拍到了灿烂的星星织锦

The brilliant tapestry of young stars flaring to life resembles a glittering fireworks display in this Hubble Space Telescope image. The sparkling centerpiece of this fireworks show is a giant cluster of thousands of stars called Westerlund 2. The cluster resides in a raucous stellar breeding ground known as Gum 29, located 20,000 light-years away from Earth in the constellation Carina. Hubble’s Wide Field Camera 3 pierced through the dusty veil shrouding the stellar nursery in near-infrared light, giving astronomers a clear view of the nebula and the dense concentration of stars in the central cluster. The cluster measures between six light-years and 13 light-years across. Image Credit: NASA, ESA, the Hubble Heritage Team (STScI/AURA), A. Nota (ESA/STScI) and the Westerlund 2 Science Team 在这张哈勃太空望远镜拍摄的照片中,闪耀着生命的年轻恒星组成的绚丽多彩的织锦就像一个闪闪发光的烟花表演。这场烟花表演的中心是一个由数千颗星星组成的巨大星团,名为韦斯特伦德2号。这个星团位于一个被称为Gum…

This artist’s concept shows exoplanet Kepler-1649c orbiting around its host red dwarf star. This exoplanet is in its star’s habitable zone (the distance where liquid water could exist on the planet’s surface) and is the closest to Earth in size and temperature found yet in Kepler’s data. For more information on the Kepler mission, visit www.nasa.gov/Kepler. For more information about exoplanets, visit https://exoplanets.nasa.gov/.
