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…

加尔维斯顿，六月节的诞生地

加尔维斯顿，六月节的诞生地

ByNASA中文

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…

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.

In this long exposure photo from June 5, 2023, a SpaceX Falcon 9 rocket creates a beam of light as it launches from Kennedy Space Center in Florida. The 28th commercial resupply mission of the Cargo Dragon spacecraft brought new science investigations, food, supplies, and equipment to the International Space Station, including IROSAs (International Space Station Roll Out Solar Arrays) that will help provide a 30% increase in power for space station research and operations once installed.

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.

“When I was a kid, I grew up watching the Moon landings. I remember watching Neil Armstrong land on the Moon, step on the lunar surface. … And so, as a kid, I wanted to be an astronaut. That was the thing – everybody wanted to be an astronaut. As I grew up, I kind of lost track of that between everything, living life and whatnot. “And so, a few years ago, when the pandemic hit, I was working for a construction contractor. Work stopped. There was nothing for me, and they laid me off. And I decided that I was due for a career change, and I wanted to get into aerospace. And I targeted, I worked very hard to find this job and…

The jellyfish galaxy JO206 trails across this image from the NASA/ESA Hubble Space Telescope, showcasing a colorful star-forming disk surrounded by a pale, luminous cloud of dust. A handful of foreground bright stars with crisscross diffraction spikes stands out against an inky black backdrop at the bottom of the image. JO206 lies over 700 million light-years from Earth in the constellation Aquarius. Jellyfish galaxies are so-called because of their resemblance to their aquatic namesakes. In the bottom right of this image, long tendrils of bright star formation trail the disk of JO206, just as jellyfish trail tentacles behind them. The tendrils of jellyfish galaxies are formed by the interaction between galaxies and the intra-cluster medium, a tenuous superheated plasma that pervades galaxy clusters. As galaxies…
