多个航天器讲述了一个巨大太阳风暴的故事

多个航天器讲述了一个巨大太阳风暴的故事

2021年4月17日,对太阳来说是平凡的一天,直到一道明亮的光闪爆发,巨大的太阳物质云从我们的恒星中喷涌而出。太阳的这种爆发并不罕见,但这一次的爆发范围异常广泛,它以接近光速的速度抛射高速质子和电子,击中了内太阳系多个航天器。

2023年11月24日 Stereo Jupiter near Opposition Image Credit & Copyright: Marco Lorenzi Explanation: Jupiter looks sharp in these two rooftop telescope images. Both were captured on November 17 from Singapore, planet Earth, about two weeks after Jupiter’s 2023 opposition. Climbing high in midnight skies the giant planet was a mere 33.4 light-minutes from Singapore. That’s about 4 astronomical units away. Jupiter’s planet girdling dark belts and light zones are visible in remarkable detail, along with the giant world’s whitish oval vortices. Its signature Great Red Spot is still prominent in the south. Jupiter rotates rapidly on its axis once every 10 hours. So, based on video frames taken only 15 minutes apart, these images form a stereo pair. Look at the center of the pair and…

2023年6月24日 3D Ingenuity Image Credit: NASA, JPL-Caltech, MSSS, ASU Explanation: The multicolor, stereo imaging Mastcam-Z on the Perseverance rover zoomed in to capture this 3D close-up (get out your red/blue glasses) of the Mars Ingenuity helicopter on mission sol 45. That’s Earth-date 2021 April 5. Casting a shadow on the Martian surface, Ingenuity is standing alone on its four landing legs next to the rover’s wheel tracks. The experimental helicopter’s solar panel, charging batteries that keep it warm through the cold Martian nights and power its flight, sits just above Ingenuity’s two 1.2 meter (4 foot) long counter-rotating blades. Thirteen sols later, on April 19, Ingenuity became the first aircraft to perform powered, controlled flight on another planet. It has since gone on to complete…

2022年12月3日 Stereo Mars near Opposition Image Credit & Copyright: Marco Lorenzi Explanation: Mars looks sharp in these two rooftop telescope views captured in late November from Singapore, planet Earth. At the time, Mars was about 82 million kilometers from Singapore and approaching its opposition, opposite the Sun in planet Earth’s sky on December 8. Olympus Mons, largest of the volcanoes in the Tharsis Montes region (and largest known volcano in the Solar System), is near Mars’ western limb. In both the images it’s the whitish donut-shape at the upper right. The dark area visible near center is the Terra Sirenum region while the long dark peninsula closest to the planet’s eastern limb is Sinus Gomer. Near its tip is Gale crater, the Curiosity rover’s landing…

2021年04月08日 3D Ingenuity Image Credit: NASA, JPL-Caltech, MSSS, ASU Explanation: The multicolor, stereo imaging Mastcam-Z on the Perseverance rover zoomed in to captured this 3D close-up (get out your red/blue glasses) of the Mars Ingenuity helicopter on mission sol 45, April 5. That’s only a few sols before the technology demonstrating Ingenuity will attempt to fly in the thin martian atmosphere, making the first powered flight on another planet. The historic test flight is planned for no earlier than Sunday, April 11. Casting its shadow on the martian surface, Ingenuity is standing alone on four landing legs next to the rover’s wheel tracks. The experimental helicopter’s solar panel, charging batteries that keep it warm through the cold martian nights and power its flight, sits above…

2020年12月11日 Messier Craters in Stereo Image Credit: Apollo 11, NASA; Stereo Image Copyright Patrick Vantuyne Explanation: Many bright nebulae and star clusters in planet Earth’s sky are associated with the name of astronomer Charles Messier from his famous 18th century catalog. His name is also given to these two large and remarkable craters on the Moon. Standouts in the dark, smooth lunar Sea of Fertility or Mare Fecunditatis, Messier (left) and Messier A have dimensions of 15 by 8 and 16 by 11 kilometers respectively. Their elongated shapes are explained by the extremely shallow-angle trajectory followed by an impactor, moving left to right, that gouged out the craters. The shallow impact also resulted in two bright rays of material extending along the surface to the…

Credit:NASA 佛罗里达载人航天倒计时;国际空间站补给任务成功完成;一款有助于月球着陆器开发的虚拟工具……最近新闻速递,尽在「本周NASA」! 最近,NASA与SpaceX进行了模拟对接任务的发射演习,为道格•赫尔利(Doug Hurley)和鲍勃•本肯(Bob Behnken)即将前往国际空间站的飞行作准备,他们将搭乘的是SpaceX公司的载人龙飞船。这项名为Demo-2的任务,将标志着NASA宇航员自航天飞机退役以来首次从美国发射升空。NASA和SpaceX计划在北京时间5月28日4时32分发射这项任务,发射地点为位于佛罗里达州肯尼迪航天中心历史悠久的39A号发射场。 5月11日,诺斯罗普•格鲁曼公司(Northrop Grumman)的无人驾驶天鹅座货运飞船驶离了国际空间站,自交付约7500磅(3400千克)的物资和科学实验已有3个多月,这些补给将支持数十项轨道前哨站上新的和现有的调查研究。这是诺斯罗普•格鲁曼公司的第13次空间站货运飞行。在弗吉尼亚州汉普顿兰利研究中心,有一个名为“月球航天器驾驶舱”(Lunar Flight Deck)的新模拟器正被用于帮助开发阿尔忒弥斯计划的人类着陆系统,让第一位人类女性和下一位人类男性登上月球。宇航员“驾驶”详细模拟版的各种月球着陆器,并给出反馈,帮助研究人员改进驾驶舱中所要使用的技术。“月球航天器驾驶舱”也可以进行重新配置,用于分析在火星上着陆的人类任务。像野火和飓风这样的自然灾害可能导致多人丧生,以及数十亿美元的损失。但是,一个名为“应急操作的可扩展流量管理”(Scalable Traffic Management for Emergency Response Operations,STEReO)的新项目,正在研究如何利用无人机来帮助应急人员更安全有效地执行操作。 STEReO由NASA位于加利福尼亚州硅谷的艾姆斯研究中心(Ames Research Center)领头,其他联邦、州和地方政府机构,第一应急人员和私人公司也参与其中。以上就是「本周 NASA」的全部内容!更多详细信息请访问 nasa.gov/twan。
