太空中的花朵

ByNASA中文 2023年6月7日

This colorful zinnia, shown in an image from Jan. 22, 2016, grew aboard the International Space Station as part of the VEG-01 experiment. This investigation assessed the on-orbit function and performance of the Veggie facility, focusing on the growth and development of seedlings in the spaceflight environment and the composition of microbial flora on the plants and the facility. For this run, zinnias were grown for 60 days and produced flowers. Learn more about the Veggie facility and other ways NASA grows plants in space.

美国桂冠诗人艾达·李蒙为欧罗巴快船揭幕诗歌

ByNASA中文 2023年6月5日

U.S. Poet Laureate Ada Limón reads her poem for the Europa Clipper mission during an event with NASA, Thursday, June 1, 2023, at the Library of Congress in Washington. The original poem, entitled “In Praise of Mystery: A Poem for Europa,” connects two water worlds – Earth and Europa. The poem will be engraved on a plaque carried aboard the Europa Clipper spacecraft as part of NASA’s “Message in a Bottle” campaign, which invites people around the world to sign their names to the poem that will journey to another world. Participants’ names will travel 1.8 billion miles (2.89 billion kilometers) aboard the Europa Clipper spacecraft, set to launch in October 2024, on its voyage to Jupiter and its moons.

VIPER团队模拟月球表面

ByNASA中文 2023年6月2日

The VIPER (Volatiles Investigating Polar Exploration Rover) engineering test team uses lunar soil simulants and hand-picked rocks to carefully shape the terrain to realistically mimic actual features at the surface of the Moon’s South Pole at in the SLOPE Lab – short for Simulated Lunar Operations Laboratory at NASA’s Glenn Research Center in Cleveland. Kevin May, rover and mission systems engineering intern at NASA’s Ames Research Center in California’s Silicon Valley led the terrain preparation for the test. “Using data and imagery from previous lunar missions, we created various randomized scenes to mimic the surface terrain of the Moon, with craters and rocks of different sizes and shapes scattered over the SLOPE tilt bed,” May said. “With help from the VIPER science team, which generated…

TROPICS准备跟踪风暴

ByNASA中文 2023年5月31日

A Rocket Lab Electron rocket stands on Pad B, Launch Complex 1, in Māhia, New Zealand, just ahead of a successful launch on Friday, May 26, with NASA’s Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) CubeSats payload. Now that the final pair of CubeSats are in orbit, TROPICS will study the formation and development of tropical cyclones, known as hurricanes in the Atlantic and typhoons in the West Pacific. Hurricane season begins June 1, and the increase of cyclone data collected by TROPICS may lead to improved tropical cyclone forecasts, ultimately helping decision makers and first responders.

“It’s important for me to be an advocate for Diversity, Equity, Inclusion, and Accessibility broadly for minorities and Asian Americans because I think I have a level of privilege that maybe other minorities may not feel that they do. I’m Asian American, Indian family, you know, privileged, not just in income and position, but also, we have the model minority myth. “It is this idea that Asian Americans are the good ones. We brought ourselves up by our bootstraps in this country, and we don’t have any problems. That we’re the successful ones. There is no discrimination. Nothing is holding us back. So, that by itself is a problem because that’s not true. But the second part of that is it’s frequently weaponized against other…

在野花间吹口哨

ByNASA中文 2023年5月25日

Two black-bellied whistling ducks walk through a field of wildflowers at Kennedy Space Center in Florida on May 19, 2023. The center shares a border with the Merritt Island National Wildlife Refuge. Merritt Island’s strategic location along the Atlantic Flyway provides a resting and feeding place for thousands of wading birds, shorebirds, and songbirds; more than 330 native and migratory bird species call Kennedy and the wildlife refuge home. Diverse habitats that include brackish marshes, saltwater estuaries, and hardwood hammocks provide homes to an amazing diversity of more than 500 species of wildlife. Learn more about how NASA uses data science for conservation at Kennedy.

The SpaceX Dragon crew spacecraft, named Freedom, is seen as it approaches the International Space Station with four Axiom Mission 2 private astronauts aboard on Monday, May 22, 2023. 11 crew members are living aboard the International Space Station with four spaceships now docked to the orbiting lab. Two SpaceX Dragon crew ships are docked adjacent to each other on the station’s Harmony module after the arrival of Axiom Mission 2 aboard Dragon on Monday at 9:12 a.m. EDT. The four private astronauts from Axiom Space opened the Dragon’s hatch at 11 a.m. and entered the station, beginning eight days of docked operations. The private quartet consisting of Commander Peggy Whitson, Pilot John Shoffner, and Mission Specialists Ali Alqarni and Rayyanah Barnawi spent Tuesday getting…

猎户座的婴儿恒星

ByNASA中文 2023年5月23日

Scores of baby stars shrouded by dust are revealed in this infrared image of the star-forming region NGC 2174, as seen by NASA’s Spitzer Space Telescope. Some of the clouds in the region resemble the face of a monkey in visible-light images, hence the nebula’s nickname: the “Monkey Head.” However, in infrared images such as this, the monkey disappears. That’s because different clouds are highlighted in infrared and visible-light images. Found in the northern reaches of the constellation Orion, NGC 2174 is located around 6,400 light-years away. Columns of dust, slightly to the right of center in the image, are being carved out of the dust by radiation and stellar winds from the hottest young stars recently born in the area. Spitzer’s infrared view provides…

哈勃太空望远镜观测到一个闪烁的星团

ByNASA中文 2023年5月20日

The densely packed globular cluster NGC 6325 glistens in this image from the NASA/ESA Hubble Space Telescope. This concentrated group of stars lies around 26,000 light-years from Earth in the constellation Ophiuchus. Globular clusters like NGC 6325 are tightly bound collections of stars with anywhere from tens of thousands to millions of members. They can be found in all types of galaxies and act as natural laboratories for astronomers studying star formation. This is because the constituent stars of globular clusters tend to form at roughly the same time and with similar initial composition, meaning astronomers can use them to fine-tune their theories of how stars evolve. Astronomers inspected this particular cluster not to understand star formation, but to search for a hidden monster. Though…
