在肯尼迪航天中心晒太阳

ByNASA中文 2023年6月28日

A young alligator rests on a concrete structure at NASA’s Kennedy Space Center in Florida on April 25, 2023. Alligator breeding season starts in May when males begin courting females. By June, pairs have mated, and females build vegetation nests in the marsh. Eggs hatch in about 65 days. The mother carries her young to the water and protects them from predators, including male alligators. The center shares a border with the Merritt Island National Wildlife Refuge. More than 330 native and migratory bird species, 25 mammal, 117 fish, and 65 amphibian and reptile species call Kennedy and the wildlife refuge home. Learn more about alligators.

以新的方式探索气候数据

ByNASA中文 2023年6月27日

Local students take in the sights—and data—at an Earth Information Center student engagement event, Friday, June 23, 2023, at NASA Headquarters in Washington. The Earth Information Center is a new immersive experience that combines live data sets with innovative data visualization and storytelling to show visitors how our planet is changing. The center gives a whole Earth view down to local information, from temperatures in our cities to sea level rise, greenhouse gas emissions to agricultural productivity. Visit this hybrid exhibit in person at NASA Headquarters in Washington or online. Take a virtual tour of the Earth Information Center.

哈勃望远镜瞥见一个闪烁的星团

ByNASA中文 2023年6月24日

The teeming stars of the globular cluster NGC 6544 glisten in this image from the NASA/ESA Hubble Space Telescope. This cluster of tightly bound stars lies more than 8,000 light-years away from Earth and is, like all globular clusters, a densely populated region of tens of thousands of stars. This image of NGC 6544 combines data from two of Hubble’s instruments, the Advanced Camera for Surveys and Wide Field Camera 3, as well as two separate astronomical observations. The first observation was designed to find a visible counterpart to the radio pulsar discovered in NGC 6544. A pulsar is the rapidly spinning remnant of a dead star, emitting twin beams of electromagnetic radiation like a vast astronomical lighthouse. This pulsar rotates particularly quickly, and astronomers…

天空实验室2号的最后一瞥

ByNASA中文 2023年6月23日

During the Skylab 2 crew’s final fly-around inspection on June 22, 1973, they saw this overhead view of the Skylab space station. It has a single solar panel and a parasol solar shield, rigged to replace the micrometeoroid shield. A mishap in the original Skylab 1 liftoff and orbital insertion resulted in damage: both the second solar panel and the micrometeoroid shield were torn away. When commander Charles “Pete” Conrad, pilot Paul J. Weitz, and science pilot Joseph P. Kerwin launched to the Skylab space station, the first part of their mission was to make repairs to the station, resulting in a record-breaking spacewalk. In the second half of their mission, Conrad, Weitz, and Kerwin focused on completing as much science as possible, research being…

发光的北海

ByNASA中文 2023年6月22日

As sunlight and warmth increase in the spring and summer, the North Sea starts to gain swirls and tendrils of color. Phytoplankton—tiny, plant-like organisms that often float near the ocean surface—become abundant during this time, giving the shallow water the distinctive look seen in this June 14, 2023, image from Landsat 9. Phytoplankton turn sunlight and carbon dioxide into sugars and oxygen, and in turn, they become food for the grazing zooplankton, shellfish, and finfish of the sea. They also play an important but not fully understood role in the global carbon cycle, taking carbon dioxide out of the atmosphere and sinking it to the bottom of the ocean. NASA’s future Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite mission will allow researchers to infer more…

Astronauts Reid Wiseman of NASA (left), Jeremy Hansen of the Canadian Space Agency (middle), and Victor Glover of NASA (right) pay close attention to Moon samples as they receive a lesson in the Apollo Lunar Lab at NASA’s Johnson Space Center in Houston on May 9, 2023. Wiseman, Hansen, and Glover, along with Christina Koch, will venture around the Moon on Artemis II, the first crewed mission on NASA’s path to establishing a long-term presence at the Moon for science and exploration.

加尔维斯顿，六月节的诞生地

ByNASA中文 2023年6月17日

Though President Abraham Lincoln issued the Emancipation Proclamation on Jan. 1, 1863, many enslaved African Americans remained unaware of this executive order for an additional two and a half years. On June 19, 1865, Union troops read out General Order No. 3 at several locations throughout Galveston, Texas, announcing the end of legalized slavery and spreading the news of freedom. That day of liberation became known as Juneteenth, the oldest known celebration commemorating the end of slavery in the United States. On June 17, 2021, President Joe Biden signed legislation to make Juneteenth a federal holiday. This image of Galveston was taken by the Expedition 67 crew aboard the International Space Station on June 20, 2022, as it orbited 224 miles above. Photo Credit: NASA…

阿尔忒弥斯2号模块有所行动

ByNASA中文 2023年6月16日

The European Service Module for the Artemis II Orion spacecraft moves into the Final Assembly and System Testing Cell at NASA’s Kennedy Space Center in this image from May 22, 2023. Here, teams are performing final checkouts on the service module, which will fuel and propel Orion in space, before integrating it with the crew module. After, the crew and service modules will be handed over to NASA’s Exploration Ground Systems for fueling. See progress on Artemis II, the first Artemis mission with crew.

太空漫步者伍迪·霍伯格驾驶着加拿大2号机械臂

ByNASA中文 2023年6月14日

During a spacewalk on June 9, 2023, NASA astronaut and Expedition 68 Flight Engineer Woody Hoburg rides the Canadarm2 robotic arm while maneuvering a roll-out solar array toward the International Space Station’s truss structure 257 miles above the Pacific Ocean. In the rear, is the SpaceX Dragon crew vehicle that docked to the Harmony module’s forward port on March 3 carrying four SpaceX Crew-6 crew members. The spacewalk with astronauts Steve Bowen and Woody Hoburg of NASA lasted 6 hours and 3 minutes. This was the ninth spacewalk for Bowen and the first for Hoburg.
