Jezero陨石坑，毅力号火星探测器的着陆点

ByNASA中文 2020年7月29日2020年7月29日

This image of Jezero Crater, the landing site for the Mars Perseverance Rover, was taken by instruments on NASA’s Mars Reconnaissance Orbiter, which regularly takes images of potential landing sites for future missions. NASA chose Jezero crater as the landing site for the Perseverance rover because scientists believe the area was once flooded with water and was home to an ancient river delta. Jezero crater tells a story of the on-again, off-again nature of the wet past of Mars. More than 3.5 billion years ago, river channels spilled over the crater wall and created a lake. Scientists see evidence that water carried clay minerals from the surrounding area into the crater lake. Conceivably, microbial life could have lived in Jezero during one or more of…

把望远镜举高至空中

ByNASA中文 2020年7月28日2020年7月28日

Carried by a balloon the size of a football stadium, ASTHROS will use a telescope to observe wavelengths of light that aren’t visible from the ground. Work has begun on ASTHROS (short for Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths), a new mission that will carry a cutting-edge 8.4-foot telescope high into the stratosphere on a balloon that is tentatively planned to launch in December 2023 from Antarctica. This illustration shows a high-altitude balloon ascending into the upper atmosphere. When fully inflated, these balloons are 400 feet (150 meters) wide, or about the size of a football stadium, and reach an altitude of 130,000 feet (24.6 miles or 40 kilometers). Image Credit: NASA/Goddard Space Flight Center Conceptual Image Lab/Michael Lentz 由一个足球场大小的气球携带，ASTHROS将使用望远镜来观察从地面看不到的波长的光。ASTHROS(用于在亚毫米波长下进行高光谱分辨率观测的天体物理平流层望远镜的简称)的工作已经开始。这是一个新的任务，它将把一个8.4英尺高的尖端望远镜通过一个气球带到平流层，这个气球暂定于2023年12月从南极洲发射。这张插图显示了一个上升到高层大气的高空气球。充足气后，这些气球宽400英尺(150米)，相当于一个足球场的大小，高度可达130,000英尺(24.6英里或40公里)。…

大黄蜂号上的阿波罗11号

ByNASA中文 2020年7月25日2020年7月25日

This image, taken on July 24, 1969, shows the Apollo 11 command module and the Mobile Quarantine Facility (MQF) photographed aboard the USS Hornet, prime recovery ship for the historic first lunar landing mission. The Apollo 11 crew, Neil Armstrong, Michael Collins and Buzz Aldrin, are already in the MQF. The Apollo 11 crew splashed down at 12:49 p.m. EDT, July 24, 1969, about 834 miles southwest of Hawaii and only 14 miles from the USS Hornet. While Armstrong and Aldrin descended in the lunar module Eagle to explore the Sea of Tranquility region of the Moon, command module pilot Collins remained with the command and service module Columbia in lunar orbit. Image Credit: NASA 这张照片拍摄于1969年7月24日，照片上的是位于美国大黄蜂号航空母舰上的阿波罗11号指令舱和移动隔离设施(MQF)，这艘美国“大黄蜂”号是美国历史上首次登月任务的主要回收船。阿波罗11号的宇航员尼尔·阿姆斯特朗、迈克尔·柯林斯和巴兹·奥尔德林已经进入MQF。1969年7月24日美国东部时间下午12点49分，阿波罗11号的机组人员在夏威夷西南834英里处溅落，距离美国大黄蜂号航空母舰仅14英里。阿姆斯特朗和奥尔德林登上月球舱鹰探索月球的宁静海地区时，指挥舱飞行员柯林斯留在月球轨道上的哥伦比亚指挥和服务舱。影像来源：NASA

NEOWISE彗星横越孤松湖上方的天空

ByNASA中文 2020年7月25日2020年7月25日

Faintly in the distance, Comet C/2020 F3 NEOWISE (Comet NEOWISE) streaked across the sky above the tree line of Lone Pine Lake, located on the Mount Whitney Trail in the Eastern Sierra Nevada Mountains in California. The comet next returns in 6,800 years. Visiting from the distant parts of our Solar System, NEOWISE is characterized by a glowing tail and is visible during the month of July. The photo was taken at 4:59 am on July 14, 2020. Want to see it for yourself? Learn how. Image Credit: NASA/Lauren Hughes 在远处，C / 2020 F3 NEOWISE（彗星NEOWISE）彗星微微划过天空，位于加利福尼亚州内华达山脉东部惠特尼山步道上的孤松湖林线上方。这颗彗星将在6800年后返回地球。 NEOWISE彗星从我们太阳系的遥远地方来访，它的特征是尾巴发光，在七月可见。这张照片摄于2020年7月14日上午4:59。想亲眼看看吗？学习如何去做。影像来源：NASA/Lauren Hughes

开发将人类送入火星的技术

ByNASA中文 2020年7月25日2020年7月25日

NASA is developing technologies to send humans to the Red Planet. The agency is working on an inflatable heat shield that allows the large surface area to take up less space in a rocket than a rigid one. The technology could land spacecraft on any planet with an atmosphere. It would expand and inflate before it enters the Martian atmosphere to land cargo and astronauts safely. In this image, engineers prepare for the flexible heat shield installation on the inflatable structure. The view is from bottom side, and the heat shield is on top. The technology isn’t ready for the Red Planet just yet. An upcoming flight test of a 6-meter diameter (about 20 feet) prototype will demonstrate how the aeroshell performs as it enters…

阿波罗11号:从月球返回

ByNASA中文 2020年7月22日2020年7月22日

On July 21, 1969, command and service module pilot Michael Collins photographed this close-up view of the docking target on the Apollo 11 Lunar Module from the Command Module. The image was captured during docking in lunar orbit as Mission Commander Neil Armstrong and lunar module pilot Buzz Aldrin returned from the lunar surface. Collins had remained in lunar orbit while Armstrong and Aldrin explored the lunar surface. Armstrong and Aldrin spent 21 hours, 36 minutes on the Moon’s surface. During the mission’s spacewalk, Aldrin deployed the Early Apollo Scientific Experiments Package, or EASEP, experiments, and Armstrong and Aldrin gathered and verbally reported on the lunar surface samples. The entire spacewalk lasted more than two-and-a-half hours, ending at 111 hours, 39 minutes into the mission….

我们为全人类的和平而来

ByNASA中文 2020年7月21日2020年7月21日

On July 20, 1969, two American astronauts made history by landing on the surface of another celestial body. This image is a close-up view of the plaque, which Apollo 11 Commander Neil Armstrong and lunar module pilot Buzz Aldrin left on the Moon in commemoration of the historic lunar landing mission. The plaque was attached to the ladder on the landing gear strut on the descent stage of the Apollo 11 lunar module. The plaque was covered with a thin sheet of stainless steel during flight. Astronaut Michael Collins, command module pilot, remained with the command and service modules in lunar orbit while Armstrong and Aldrin explored the Moon.

阿波罗-联盟号测试项目:轨道伙伴关系诞生

ByNASA中文 2020年7月19日2020年7月19日

On July 17, 1975, something momentous happened: two Cold War rivals met in space. When their respective spacecraft rendezvoused and docked, a new era of cooperative ventures in space began. For more than two decades, American astronauts and Russian cosmonauts have been regularly living and working together in Earth orbit, first in the Shuttle-Mir program, and now on the International Space Station. But, before the two Cold War-rivals first met in orbit in 1975, such a partnership seemed unlikely. Since Sputnik bleeped into orbit in 1957, there had been a Space Race, with the U.S. and then-Soviet Union driven more by competition than cooperation. When President John F. Kennedy called for a crewed Moon landing in 1961, he spoke of “battle that is now going…
