初代吸血鬼

一 | CAPE CANAVERAL, Fla. -- NASA’s Psyche spacecraft rocketed away Friday on a six-year journey to a rare metal-covered asteroid.Most asteroids tend to be rocky or icy, and this is the first exploration of a metal world. Scientists believe it may be the battered remains of an early planet's core, and could shed light on the inaccessible centers of Earth and other rocky planets.SpaceX launched the spacecraft into an overcast midmorning sky from NASA’s Kennedy Space Center. Named for the asteroid it’s chasing, Psyche should reach the huge, potato-shaped object in 2029.“It's so thrilling,” said Laurie Leshin, director of NASA’s Jet Propulsion Laboratory. Added Arizona State University's Jim Bell, part of the Psyche team: “What a great ride so far.”An hour later, the spacecraft separated successfully from the rocket's upper stage and floated away, drawing applause from ground controllers.After decades of visiting faraway worlds of rock, ice and gas, NASA is psyched to pursue one coated in metal. Of the nine or so metal-rich asteroids discovered so far, Psyche is the biggest, orbiting the sun in the outer portion of the main asteroid belt between Mars and Jupiter alongside millions of other space rocks. It was discovered in 1852 and named after Greek mythology’s captivating goddess of the soul.“It’s long been humans’ dream to go to the metal core of our Earth. I mean, ask Jules Verne,” lead scientist Lindy Elkins-Tanton of Arizona State University said ahead of the launch. “The pressure is too high. The temperature is too high. The technology is impossible,” she said. “But there’s one way in our solar system that we can look at a metal core and that is by going to this asteroid.”Astronomers know from radar and other observations that the asteroid is big — about 144 miles (232 kilometers) across at its widest and 173 miles (280 kilometers) long. They believe it’s brimming with iron, nickel and other metals, and quite possibly silicates, with a dull, predominantly gray surface likely covered with fine metal grains from cosmic impacts.Otherwise, it’s a speck of light in the night sky, full of mystery until the spacecraft reaches it after traveling more than 2 billion miles (3.6 billion kilometers).Scientists envision spiky metal craters, huge metal cliffs and metal-encrusted eroded lava flows greenish-yellow from sulfur — “almost certain to be completely wrong,” according to Elkins-Tanton. It's also possible that trace amounts of gold, silver, platinum or iridium — iron-loving elements — could be dissolved in the asteroid's iron and nickel, she said. “There's a very good chance that it’s going to be outside of our imaginings, and that is my fondest hope," she said.Believed to be a planetary building block from the solar system’s formation 4.5 billion years ago, the asteroid can help answer such fundamental questions as how did life arise on Earth and what makes our planet habitable, according to Elkins-Tanton.On Earth, the planet's iron core is responsible for the magnetic field that shields our atmosphere and enables life.Led by Arizona State University on NASA’s behalf, the $1.2 billion mission will use a roundabout route to get to the asteroid. The van-size spacecraft with solar panels big enough to fill a tennis court will swoop past Mars for a gravity boost in 2026. Three years later, it will reach the asteroid and attempt to go into orbit around it, circling as high as 440 miles (700 kilometers) and as close as 47 miles (75 kilometers) until at least 2031.The spacecraft relies on solar electric propulsion, using xenon gas-fed thrusters and their gentle blue-glowing pulses. An experimental communication system is also along for the ride, using lasers instead of radio waves in an attempt to expand the flow of data from deep space to Earth. NASA expects the test to yield more than 10 times the amount of data, enough to transmit videos from the moon or Mars one day.The spacecraft should have soared a year ago, but was held up by delays in flight software testing attributed to poor management and other issues. The revised schedule added extra travel time. So instead of arriving at the asteroid in 2026 as originally planned, the spacecraft won’t get there until 2029.That’s the same year that another NASA spacecraft — the one that just returned asteroid samples to the Utah desert — will arrive at a different space rock as it buzzes Earth.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Science and Educational Media Group.

二 | ”于是，孩子们寻着桂花香，与桂花相遇，开启了一场与秋天最美的邂逅。解桂花秘孩子们通过完成桂花的秘密调查表，了解了桂花的种类、用途、颜色、气味等。桂花的种类通过教学活动，我们了解到桂花主要分为四个品种：金桂、银桂、丹桂和四季桂。看一看孩子们把桂花带到班级，并近距离地对桂花进行了观察，通过自己的观察、比较、分析，孩子们有了新的发现。

三 | 汐汐我发现一朵桂花有四个花瓣。桂花的叶子是椭圆形的。小杰宇昊桂花的颜色有的深，有的浅。我觉得桂花的味道很香、很好闻。欣欣孩子们在探秘过程中，通过闻一闻、看一看以及数一数等方式，发现了不同的桂花有不同的香味、桂花花瓣的数量以及桂花花蕊和花瓣颜色的差别等。寻桂花源在我们了解桂花的叶子、花朵、枝干的外貌特征之后，我们带着这样的记忆开始了在园内寻找桂花的旅程。寻桂计划在活动开始前，幼儿自主制定了寻桂路线图，确定了寻桂的地点和路线。寻桂途中孩子们参考路线图，在教室门口、操场边、沙池边、菜地附近展开了一场搜罗。

四 | 小操场 01 滑滑梯边 02 沙池边 03 菜地旁 04 桂花分布统计表采桂花行大自然、大社会是活教育，我们充分利用家长资源，一起收集关于桂花的资料，丰富孩子们对桂花的经验。家长带领孩子到大自然中寻找桂花、观察桂花、欣赏桂花，采摘桂花，在与大自然的接触中与桂花进行亲密接触。 AUTUMN 向左滑动查看更多集桂花美画桂花桂花香囊闻一闻，好香呀！桂花书签想不到桂花还能做成书签呢看我的书签漂亮吧！唱一唱香香的桂花唱成甜甜的歌谣，一起来听听小朋友的歌声吧！点击边框调出视频工具条尝桂花甜制作桂花糕 Part. 01 称出100克的发糕粉，要倒慢一点看好称上的数字哦~ Part. 02 再倒出100克的饮用水。 Part. 03 再加点牛奶会不会更好吃呢~ Part. 04 搅拌均匀，一直到看不到颗粒为止。 Part. 05 再撒上桂花，又香又好看！ Part. 06 放入蒸锅，静静等待20分钟。 Part. 07 时间到啦，好香的味道呀！自己做的桂花糕真是太美味啦！品桂花茶泡茶闻香课程总结大自然是孩子们进行自然探究的“活教材”，在本次活动中，我们充分挖掘本地的自然资源，引导孩子在自然探究中积累有益经验，帮助他们与大自然建立紧密的联系。在与桂花的一场“香”遇的路途中，我们不仅留住了花香，还获得了宝贵的合作意识和求索精神。通过一系列的活动，幼儿自己发现、探索、研究了桂花，还用桂花制作了香囊、书签、美食等，用自己的方法把桂花留了下来，这不仅仅体现出孩子们的动手能力，还萌发了孩子们的思考，制作的过程更像综合游戏，给予幼儿更多的经验，让幼儿对于桂花有了更进一步的了解。在生活中追求教育，在教育中体验生活，浓浓桂花情，见证着孩子们的精彩成长。感谢一朵朵桂花，让我们认识一个诗意的秋，也期待来年金秋桂花开时，能与秋再来一场浪漫的邂逅。
