Earth’s Moon is seen rising behind NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard atop a mobile launcher as it rolls out to Launch Complex 39B for the first time, Thursday, March 17, 2022, at NASA’s Kennedy Space Center in Florida. Ahead of the Artemis I flight test, the fully stacked and integrated SLS rocket and Orion spacecraft will undergo a wet dress rehearsal to verify systems and practice countdown procedures for the first launch.

Dr. Eugene N. Parker, visionary of heliophysics and namesake of NASA’s Parker Solar Probe, has passed away. He was 94. As a young professor at the University of Chicago in the mid-1950s, Parker developed a mathematical theory that predicted the solar wind, the constant outflow of solar material from the Sun. Throughout his career, Parker revolutionized the field time and again, advancing ideas that addressed the fundamental questions about the workings of our Sun and stars throughout the universe. In this image, Parker(center)visited the spacecraft that bears his name, NASA’s Parker Solar Probe, on Oct. 3, 2017. Engineers in the clean room at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, where the probe was designed and built point out the instruments that will…

NASA宇航员打破美国太空记录

NASA宇航员打破美国太空记录

In this image from August 2021, NASA astronaut Mark Vande Hei sits and reads while aboard the International Space Station. Vande Hei made it into record books on Tuesday, March 15, 2022: He broke the record for the most consecutive days in space by an American explorer. Vande Hei arrived at the space station on April 9, 2021, and is expected to return home March 30, 2022, after spending 355 days in low-Earth orbit. This duration breaks the previous record, held by NASA astronaut Scott Kelly, by 15 days. His then-crewmate Thomas Pesquet, who snapped the picture, said: “If you are reading this sitting down, maybe on a sofa or couch, consider that we will not sit down… until we are back on Earth! Of…

Today is Pi Day, March 14, 2022! Each year NASA celebrates pi with a host of educational activities that focus on its importance to our missions. This “Pi in the Sky” math challenge gives students a chance to take part in recent discoveries and upcoming celestial events, all while using math and pi just like NASA scientists and engineers. In this problem, students use the mathematical constant pi to calculate the volume and density of Mars’ liquid core. Since 2018, the InSight lander has studied the interior of Mars by measuring vibrations from marsquakes and the “wobble” of the planet as it rotates on its axis. Through careful analysis of the data returned from InSight, scientists were able to measure the size of Mars’ liquid…

哈勃望远镜观测到一颗新生恒星的爆发

哈勃望远镜观测到一颗新生恒星的爆发

ByNASA中文

An energetic outburst from an infant star streaks across this image from the NASA/ESA Hubble Space Telescope. This stellar tantrum – produced by an extremely young star in the earliest phase of formation – consists of an incandescent jet of gas travelling at supersonic speeds. As the jet collides with material surrounding the still-forming star, the shock heats this material and causes it to glow. The result is the colorfully wispy structures, which astronomers refer to as Herbig–Haro objects, billowing across the lower right of this image. Herbig–Haro objects are seen to evolve and change significantly over just a few years. This particular object, called HH34, was previously captured by Hubble between 1994 and 2007, and again in glorious detail in 2015. HH34 resides approximately…

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 ASTER bands 4-2-1 displayed in RGB. With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of about 50 to 300 feet (15 to 90 meters), ASTER images Earth to map and monitor the changing surface of our planet and is one of five Earth-observing instruments launched Dec. 18, 1999, on the Terra satellite. The instrument was built by Japan’s Ministry of…

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) software that will tell the rocket how to operate for the first 8 minutes of the Artemis I mission during its launch and ascent to orbit. Their work continues Marshall’s legacy of propelling NASA exploration through engineering. Built and managed by the Flight and Ground Software and Simulation Division, the SIL, or System Integration Lab, at Marshall is where Space Launch System flight software is validated, and SLS System performance…

发射探测器以研究脉动极光

发射探测器以研究脉动极光

ByNASA中文

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 occasionally protons) from near-Earth space. These electrons plunge into our atmosphere and collide with atoms and molecules, causing them to glow in their distinctive colors – red and green by oxygen, blue by nitrogen – as they release their excess energy. Image Credit: NASA LAMP任务是极光微爆发脉动损失的简称，于2022年3月5日星期六搭载Black Brant IX亚轨道探空火箭发射升空。这项任务将研究一种经常被忽视的极光，称为脉动极光，并测试其成因的理论。 像所有的极光一样，脉动极光是由近地空间的电子（偶尔也有质子）点燃。这些电子进入我们的大气层，与原子和分子碰撞，使它们在释放多余能量时发出独特的颜色——氧气发出红色和绿色，氮气发出蓝色。 图片来源：NASA
