Dr. Christian Braneon, a climate scientist at NASA’s Goddard Institute for Space Studies (GISS) in New York City, presents data visualizations and the state of current satellite missions to Vice President Kamala Harris on Nov. 5, 2021, at the NASA Goddard Space Flight Center in Greenbelt, Maryland. 克里斯蒂安·布拉尼恩博士是NASA戈达德空间研究所（GISS）驻纽约的气候科学家，他于2021年11月5日在...
The bright Sun dissects the airglow above Earth’s horizon in this view photographed with a digital still camera from the space shuttle Columbia during the STS-107 mission. 在STS-107任务期间，从哥伦比亚号航天飞机上用数码相机拍摄到的这一景象中，明亮的太阳分割了地球地平线上的气辉。 Columbia and the STS-107 crew perished during re-entry on Feb. 1, 2003. 哥伦比亚号和STS-107机组人员在2003年2月1日重返大气层时遇难。 Day of Remembra...
To learn how ocean water is melting glaciers, NASA’s Oceans Melting Greenland mission extensively surveyed the coastline of the world’s largest island. The airborne mission found that Greenland’s glaciers that empty into the ocean, like Apusiaajik Glacier shown here, are at greater risk of rapid ice loss than previously understood. 为了了解海水是如何融化冰川的，NASA的...
In this image taken in 1985, four members of the Challenger STS-51L crew – Michael J. Smith, left, Ellison S. Onizuka, Judith A. Resnik, and Francis R. “Dick” Scobee – train on the flight deck of the shuttle crew compartment. 在1985年拍摄的这张照片中，挑战者号STS-51L机组的四名成员——迈克尔·J·史密斯（左）、埃里森·S·奥尼苏卡、朱迪思·A·雷斯尼克和弗朗西斯·R·迪克·斯科比在航天飞机机组人员舱的飞行甲板上接受训练。 Just 73 seconds after launch ...
In this June 1966 photo, the Apollo 1 crew practices water egress procedures with a full scale boilerplate model of the spacecraft. In the water at right are astronauts Ed White and Roger Chaffee (foreground). In raft near the spacecraft is astronaut Gus Grissom. NASA swimmers are in the water to assist in the practice session that took place at Ellington AF...
Much like the sky, rivers are rarely painted one color. Rivers around the world appear in shades of yellow, green, blue, and brown—and subtle changes in the environment can alter their colors. 就像天空一样，河流很少被涂成一种颜色。世界各地的河流呈现出黄色、绿色、蓝色和棕色的色调——环境的细微变化会改变它们的颜色。 New research shows the dominant color has changed in about one-third of large rivers in the continental U...
This colorized schlieren image is of a small-scale model of NASA’s X-59 Quiet SuperSonic Technology (QueSST) airplane taken inside NASA Glenn Research Center’s 8- by- 6-foot Supersonic Wind Tunnel during a recent boom test. The multiple-week campaign produced data sets and shockwave visuals that engineers from the agency’s Commercial Supersonic Technology pr...
Venus hides a wealth of information that could help us better understand Earth and exoplanets, or those planets outside our solar system. NASA’s Jet Propulsion Laboratory is designing mission concepts to survive the planet’s extreme temperatures and atmospheric pressure. This image is a composite of data from NASA’s Magellan spacecraft and ...
The spiral arms of the galaxy NGC 3318 are lazily draped across this image from the NASA/ESA Hubble Space Telescope. This spiral galaxy lies in the constellation Vela and is roughly 115 million light-years away from Earth. Vela was originally part of a far larger constellation, known as Argo Navis after the fabled ship Argo from Greek mythology, but this unw...
In this image from Jan. 9, 2022, NASA astronaut Kayla Barron peered out from a window inside the cupola, the International Space Station’s “window to the world.” Prominent station components in this photograph include the Kibo laboratory module and its external pallet, the Japanese robotic arm, and the Leonardo Permanent Multipurpose Module...
