克服飓风和地震，进入空间站进行实验

Space is hard, the saying goes, and conducting science in space presents challenges of its own. Few researchers have had to overcome hurricanes and earthquakes, though, just two of the hurdles a team of chemists in Puerto Rico faced getting their investigation to the International Space Station. In this image, Camila Morales-Navas, a chemistry Ph.D. student, conducts final preparations on the Electrochemical Ammonia Removal system prior to parabolic flight testing. #HispanicHeritageMonth Image Credit: University of Puerto Rico 俗话说，太空是艰难的，在太空中进行科学研究本身就面临着挑战。然而，很少有研究人员需要克服飓风和地震，而这只是波多黎各化学家团队在国际空间站进行研究时面临的两个障碍。 在这张图片中，卡米拉·莫拉莱斯-纳瓦斯，一名化学博士学生，在进行抛物线飞行测试前对电化学氨去除系统进行最后的准备。 #HispanicHeritageMonth 影像来源：​波多黎各大学

A Northrop Grumman Antares rocket, with the company’s Cygnus spacecraft aboard, launches at 9:16 p.m. EDT, Friday, Oct. 2, 2020, from the Mid Atlantic Regional Spaceport’s Pad-0A, at NASA’s Wallops Flight Facility in Virginia. Northrop Grumman’s 14th contracted cargo resupply mission for NASA to the International Space Station is carrying nearly 8,000 pounds of science and research, crew supplies, and vehicle hardware to the orbital laboratory and its crew. On Monday, Oct. 5, Cygnus was successfully berthed to the space station.

This stunning image by the NASA/ESA Hubble Space Telescope features the spiral galaxy NGC 5643 in the constellation of Lupus (the Wolf). Looking this good isn’t easy; 30 different exposures, for a total of nine hours of observation time, together with the high resolution and clarity of Hubble, were needed to produce an image of such high level of detail and beauty. NGC 5643 is about 60 million light-years away from Earth and has been the host of a recent supernova event (not visible in this latest image). This supernova (2017cbv) was a specific type in which a white dwarf steals so much mass from a companion star that it becomes unstable and explodes. The explosion releases significant amounts of energy and lights up that…

Our Aqua satellite captured this composite visible (left) and infrared (right) image on Sep. 29, 2020, which shows that fires and smoke continue to dominate the landscape of the western U.S. The visible image shows the smoke and the infrared image shows the heat from the fires (orange points). The California Department of Forestry and Fire Protection (CAL Fire) page for Sep. 30 finds many large fires still active throughout California and the Pacific Northwest. The August Complex in California continues to be the largest wildfire still active and uncontained at 949,055 acres, located in Glenn, Lake, Mendocino, Tehama, and Trinity Counties. The August Complex is the largest wildfire in California’s history having surpassed the Mendocino Complex fire which burned 459,123 acres in July 2018….

反光镜:从阿波罗到火星

反光镜:从阿波罗到火星

ByNASA中文

When Apollo 11 landed on the Moon, the crew brought devices with them called retroreflectors, which are essentially small arrays of mirrors. The plan was for scientists on Earth to aim lasers at them and calculate the time it took for the beams to return. This provided exceptionally precise measurements of the Moon’s orbit and shape, including how it changed slightly based on Earth’s gravitational pull. Research with these Apollo-era lunar retroreflectors continues to this day. Scientists want to perform similar experiments on the Red Planet and NASA’s Perseverance rover – scheduled to land on Mars on Feb. 18, 2021 – carries with it the Laser Retroreflector Array. There’s also small one aboard the agency’s InSight lander, called Laser Retroreflector for InSight. While there is…

Astronaut Serena Auñón-Chancellor examines her eye with a fundoscope aboard the International Space Station with remote support from doctors on the ground. As a member of the Expedition 56/57 crew in 2018, she participated in many onboard experiments in biology, biotechnology, physical science and Earth science aboard the station Dr. Auñón-Chancellor was selected as a member of the Astronaut Corps in 2009. She is board certified in Internal and Aerospace Medicine. During her time aboard the station, the crew led investigations into new cancer treatment methods and algae growth in space. The crew also installed a new Life Sciences Glovebox, a sealed work area for life science and technology investigations that can accommodate two astronauts. During this, her first flight, she logged in 197 days…

Humanity has “eyes” that can detect all different types of light through telescopes around the globe and a fleet of observatories in space. From radio waves to gamma rays, this “multiwavelength” approach to astronomy is crucial to getting a complete understanding of objects in space. This image is of galaxy cluster Abell 2744. Galaxy clusters are the largest objects in the universe held together by gravity. They contain enormous amounts of superheated gas, with temperatures of tens of millions of degrees, which glows brightly in X-rays, and can be observed across millions of light years between the galaxies. This image combines X-rays from the Chandra X-Ray Observatory (diffuse blue emission) with optical light data from the Hubble Space Telescope (red, green, and blue). See a…

木星北极的彩色旋风

ByNASA中文

Cyclones at the north pole of Jupiter appear as swirls of striking colors in this extreme false color rendering of an image from NASA’s Juno mission. The huge, persistent cyclone found at Jupiter’s north pole is visible at the center of the image, encircled by smaller cyclones that range in size from 2,500 to 2,900 miles (4,000 to 4,600 kilometers). Together, this pattern of storms covers an area that would dwarf the Earth. The color choices in this image reveal both the beauty of Jupiter and the subtle details present in Jupiter’s dynamic cloud structure. Each new observation that Juno provides of Jupiter’s atmosphere complements computer simulations and helps further refine our understanding of how the storms evolve over time. The Juno mission provided the…
