造福地球生命的产品和服务为太空开发技术带来了新的发展。其中包括位于阿拉巴马州亨茨维尔的NASA马歇尔太空飞行中心的发明。 NASA的工程师和科学家经常在执行任务的过程中开发新技术。虽然这项技术的起源通常是为了帮助探索太阳系及更远的地方。但NASA的技术转让计划通过将它们授权给公司和企业家，将它们带回地球。 然后，被许可方创造新的产品和服务，称为“衍生产品”，这有利于经济、保护环境，甚至拯救生命。 NASA的2,000多个衍生产品中，其中最常见的是手机摄像头、婴儿配方奶粉和飞机翼梢小翼。 NASA的技术转让计划有超过1,200项技术可供许可使用。潜在的许可方可以在线浏览整个投资组合，它们按通信、医疗、环境、制造等类别进行组织。如果产品获得许可，发明者还可以分享专利使用费。 “在技术转让方面，我们有机会与NASA工...
2022年3月10日 Globular Star Cluster 47 Tuc Image Credit & Copyright: Bernard Miller Explanation: Globular star cluster 47 Tucanae is a jewel of the southern sky. Also known as NGC 104, it roams the halo of our Milky Way Galaxy along with some 200 other globular star clusters. The second brightest globular cluster (after Omega Centauri) as seen from planet ...
The Pilbara in northwestern Australia exposes some of the oldest rocks on Earth, over 3.6 billion years old. The iron-rich rocks formed before the presence of atmospheric oxygen, and life itself. Found upon these rocks are 3.45 billion-year-old fossil stromatolites, colonies of microbial cyanobacteria. The image, acquired in October 2004, is a composite of A...
2022年3月9日 A Flower-Shaped Rock on Mars Image Credit: NASA, JPL-Caltech, MSSS Explanation: It is one of the more unusual rocks yet found on Mars. Smaller than a penny, the rock has several appendages that make it look, to some, like a flower. Although it would be a major discovery if the rock was truly a fossilized ancient Martian flower, there are less spect...
In honor of Women’s History Month, NASA celebrates the many contributions women have made to the nation, world, and beyond, including five women at Marshall Space Flight Center in Huntsville, Alabama, who developed flight software that will control the rocket for Artemis missions to the Moon. These engineers developed and tested Space Launch System (SLS) sof...
NASA的普赛克航天器上的两个太阳能阵列中的一个已成功部署在JPL的高层高湾2号洁净室。在前往火星和木星之间的小行星带执行任务期间，这两个阵列将为航天器及其科学仪器提供动力。 影像来源：NASA/JPL加州理工学院 太阳能电池阵列安装好后，航天器接近其最终配置，计划于8月发射。 NASA的普赛克任务已经基本准备就绪，即将进入太阳系——一个15亿英里（24亿公里）的太阳能旅程，前往一颗神秘的、富含金属的同名小行星。两个太阳能电池阵列已经连接到航天器的机身上，纵向展开，然后重新折叠存放。这次测试使飞船离8月发射升空更近了一步。 “第一次看到航天器完全组装好是一项巨大的成就；我们感到非常自豪。”在NASA位于南加州的喷气推进实验室领导该任务的组装、测试和发射操作的布莱恩·伯恩说。“这是真正有趣的部分。你感觉这一切都融...
2022年3月8日 Moon in Inverted Colors Image Credit & Copyright: Dawid Glawdzin Explanation: Which moon is this? It’s Earth’s moon — but in inverted colors. Here, the pixel values corresponding to light and dark areas have been translated in reverse, or inverted, producing a false-color representation reminiscent of a black and white photog...
The LAMP mission, short for Loss through Auroral Microburst Pulsations, launched on Saturday, Marc 5, 2022, aboard a Black Brant IX suborbital sounding rocket. The mission will study an often overlooked kind of aurora, called a pulsating aurora, and test a theory on what causes them. Like all aurora, a pulsating aurora is set alight by electrons (and occasio...
