马克·范德·黑和机组成员安全着陆

ByNASA中文 2022年4月1日2022年4月1日

Record-setting NASA astronaut Mark Vande Hei, left, and cosmonauts Anton Shkaplerov, center, and Pyotr Dubrov of Rosccosmos are seen inside their Soyuz MS-19 spacecraft after landing in a remote area near the town of Zhezkazgan, Kazakhstan, Wednesday, March 30, 2022. Vande Hei and Dubrov are returning to Earth after logging 355 days in space as members of Expeditions 64-66 aboard the International Space Station. For Vande Hei, his mission is the longest single spaceflight by a U.S. astronaut in history. Shkaplerov is returning after 176 days in space, serving as commander of Expedition 66.

马克·范德·黑的归来

ByNASA中文 2022年3月30日2022年3月30日

NASA astronaut Mark Vande Hei arrived at the International Space Station on April 9, 2021, and will return home March 30, 2022, after spending 355 days in low-Earth orbit. This duration breaks the previous record, held by retired NASA astronaut Scott Kelly, by 15 days. Vande Hei will return in a Soyuz spacecraft as scheduled alongside cosmonauts Pyotr Dubrov and Anton Shkaplerov. While clocking the single longest spaceflight by a NASA astronaut, Vande Hei contributed to dozens of studies from the hundreds executed during his mission, including six science investigations supported by NASA’s Human Research Program, or HRP. In this image from March 2017, Vande Hei trained for a spacewalk at NASA’s Johnson Space Center in Houston. Image Credit: NASA NASA宇航员马克·范德·黑于2021年4月9日抵达国际空间站，并将于2022年3月30日返回地球，此前他在近地轨道上度过了355天。这一时长打破了之前由NASA退休宇航员斯科特·凯利保持的340天纪录。范德·黑将按计划与宇航员彼得·杜布罗夫和安东·什卡普列罗夫一起乘坐联盟号宇宙飞船返回。这是NASA宇航员进行的最长的一次太空飞行，范德·黑在执行任务期间为数百项研究做出了贡献，其中包括NASA人类研究计划（HRP)）支持的六项科学调查。在这张2017年3月的照片中，范德·黑在休斯顿的NASA约翰逊航天中心进行太空行走训练。图片来源：NASA

相互碰撞：如何创造岩石行星

ByNASA中文 2022年3月29日2022年3月29日

Major smashups between rocky bodies shaped our solar system. Observations of a similar crash give clues about how frequent these events are around other stars. Most of the rocky planets and satellites in our solar system, including Earth and the Moon, were formed or shaped by massive collisions early in the solar system’s history. By smashing together, rocky bodies can accumulate more material, increasing in size, or they can break apart into multiple smaller bodies. Astronomers using NASA’s now-retired Spitzer Space Telescope have in the past found evidence of these types of collisions around young stars where rocky planets are forming. But those observations didn’t provide many details about the smashups, such as the size of the objects involved. This illustration depicts the result of…

开创性的女飞行员沃利·芬克赢得 2022 年迈克尔·柯林斯终身成就奖

ByNASA中文 2022年3月26日2022年3月26日

Wally Funk delivers remarks after accepting the 2022 Michael Collins Trophy for Lifetime Achievement, Thursday, March 24, 2022, at the Smithsonian National Air and Space Museum’s Steven F. Udvar-Hazy Center in Chantilly, Va. The Smithsonian National Air and Space Museum’s Michael Collins Trophy recognizes extraordinary accomplishments in aeronautics and spaceflight. Funk was a member of the First Lady Astronaut Trainees (FLATs, also known as the “Mercury 13”). These seven women who once aspired to fly into space stand outside Launch Pad 39B near the Space Shuttle Discovery in this photograph from 1995. The so-called Mercury 13 was a group of women who trained to become astronauts for America’s first human spaceflight program in the early 1960s. Although FLATs was never an official NASA program, the…

月球上有什么新鲜事…50年后

ByNASA中文 2022年3月25日2022年3月25日

Like a time capsule that was sealed for posterity, one of the last unopened Apollo-era lunar samples collected during Apollo 17 has been opened under the careful direction of lunar sample processors and curators in the Astromaterials Research and Exploration Science (ARES) Division at NASA’s Johnson Space Center in Houston. This precious and well-preserved sample will serve as a narrow window into the permanent geological record of Earth’s closest celestial neighbor – the Moon. Watch NASA TV at 3 p.m. EDT for a new episode of NASA Science Live: We Just Opened a 50-Year-Old Moon Sample. This image of Apollo 17 lunar core sample 73001 shows it being taken out of its drive tube at the Johnson Space Center in Houston for the first time…

偷运的腌牛肉和双子座III号任务

ByNASA中文 2022年3月24日2022年3月24日

The first corned beef sandwich to orbit Earth was smuggled aboard Gemini III on March 23, 1965. As contraband unapproved for flight by NASA, pilot John Young had hidden the sandwich in a pocket of his spacesuit shortly before the launch. Around two hours into the almost five-hour long flight, he offered some to the commander of the mission, Virgil “Gus” Grissom, who accepted the rye bread and preserved meat gift. The exchange over the sandwich lasted less than a minute and ended with Grissom putting the unfinished sandwich away in his own spacesuit pocket so the breadcrumbs that were breaking off would be less likely to float behind an instrument panel or into one of the astronaut’s eyes. The approved food for the flight,…

5000颗系外行星并在不断增加

ByNASA中文 2022年3月23日2022年3月23日

Not so long ago, humanity lived in a universe with only a small number of known planets, all of them orbiting our Sun. But a new raft of discoveries marks a scientific high point: More than 5,000 planets are now confirmed to exist beyond our solar system. The planetary odometer turned on March 21, with the latest batch of 65 exoplanets – planets outside our immediate solar family – added to the NASA Exoplanet Archive. The archive records exoplanet discoveries that appear in peer-reviewed, scientific papers, and that have been confirmed using multiple detection methods or by analytical techniques. This artist’s concept is of a Jupiter-mass planet orbiting the nearby star Epsilon Eridani, located 10.5 light-years away from Earth. Learn more What are exoplanets? Cosmic…

星云的景象

ByNASA中文 2022年3月22日2022年3月22日

This colorful image, taken by the Hubble Space Telescope and published in 2018, celebrated the Earth-orbiting observatory’s 28th anniversary of viewing the heavens, giving us a window seat to the universe’s extraordinary tapestry of stellar birth and destruction. At the center of the photo, a monster young star 200,000 times brighter than our Sun is blasting powerful ultraviolet radiation and hurricane-like stellar winds, carving out a fantasy landscape of ridges, cavities, and mountains of gas and dust. This mayhem is all happening at the heart of the Lagoon Nebula, a vast stellar nursery located 4,000 light-years away and visible in binoculars simply as a smudge of light with a bright core. The giant star, called Herschel 36, is bursting out of its natal cocoon of…
