Astronaut Serena Auñón-Chancellor installs samples for the Microgravity Investigation of Cement Solidification (MICS) experiment aboard the International Space Station (ISS) in this image from Nov. 27, 2018. MICS explored how cement solidified in microgravity, important research for constructing safe space habitats on the Moon or Mars and for improving cement processing on Earth. Dr. Auñón-Chancellor was selected in July 2009 as one of 14 members of the 20th NASA astronaut class. During Astronaut Candidate Training, she spent 2 months in Antarctica from 2010 to 2011 searching for meteorites as part of the Antarctic Search for Meteorites expedition. Most of that time was spent living on the ice 200 nautical miles from the South Pole. Her first flight was to the ISS, where she logged 197…

Astronaut Nicole Mann sits inside a T-38 trainer jet at Ellington Field in Houston, Texas, in this image from Nov. 15, 2018. She served as the T-38 safety and training officer; T-38s are used for pilot proficiency and training for astronauts. Selected as an astronaut candidate in June 2013, Mann will be the first Indigenous woman from NASA in space. In her first spaceflight, she is scheduled to launch to the International Space Station as commander of NASA’s SpaceX Crew-5 mission aboard the SpaceX Crew Dragon spacecraft no earlier than Oct. 5, 2022. As mission commander, she will be responsible for all phases of flight, from launch to re-entry. She will serve as an Expedition 68 flight engineer aboard the station. Watch our SpaceX Crew-5…

DART的倒数第二视图

ByNASA中文 2022年10月4日2022年10月4日

This is the last complete image of the asteroid Dimorphos, as seen by our Double Asteroid Redirection Test (DART) two seconds before impact. The Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO) imager aboard captured a 100-foot-wide patch of the asteroid. The DART spacecraft streamed these images from its DRACO camera back to Earth in real time as it approached the asteroid. DART successfully impacted its target on Monday, Sept. 26, 2022, in the world’s first planetary defense technology demonstration. See more from the moments just before DART’s intentional crash. Image Credit: NASA/Johns Hopkins APL 这是小行星Dimorphos的最后一张完整图像，由我们的双小行星重定向测试（DART）在撞击前两秒拍摄。航天器上的Didymos侦察和小行星光学导航相机（DRACO）成像仪拍摄了这个100英尺宽的小行星区域。 DART航天器在接近小行星时，将这些图像从DRACO相机实时传回地球。2022年9月26日，星期一，DART成功撞击目标，这是世界上第一次行星防御技术演示。查看更多关于DART故意撞击前的瞬间。图片来源：NASA/Johns Hopkins APL

海王星在近红外线中炫耀它的行星环

ByNASA中文 2022年9月30日2022年9月30日

On Sept. 21, 2022, the James Webb Space Telescope delivered the clearest view of Neptune’s rings in more than 30 years. Webb’s Near-Infrared Camera (NIRCam) captured several bright, narrow rings as well as the planet’s fainter dust bands. Voyager 2 was the last to detect some of these rings during its flyby in 1989, but this is the first time we have an infrared image of them. Since NIRCam images objects in the near-infrared range from 0.6 to 5 microns, Neptune does not appear blue to Webb. In fact, the methane gas so strongly absorbs red and infrared light that the planet is quite dark at these near-infrared wavelengths, except where high-altitude clouds are present. Those methane-ice clouds are prominent as bright streaks and spots,…

Astronaut Ellen Ochoa, STS-110 flight engineer, wears a launch and entry suit as part of water survival training in the Neutral Buoyancy Laboratory at the Sonny Carter Training Facility near NASA’s Johnson Space Center in Houston, Texas in 2001. STS-110 was the 13th shuttle mission to visit the International Space Station (ISS). The mission included 4 spacewalks, furthering the construction of the ISS. Dr. Ochoa was selected by NASA in 1990 as the first female Hispanic astronaut and became the first Hispanic astronaut to fly to the International Space Station. Ochoa was named as the deputy director of the agency’s Johnson Space Center’s in 2007, then as the Center’s first Hispanic director and its second female director in 2013. She served in that position until…

DART团队庆祝碰撞成功

ByNASA中文 2022年9月28日2022年9月28日

In this image from Sept. 26, 2022, the Double Asteroid Redirection Test (DART) team, Dr. Thomas Zurbuchen, and guests at Johns Hopkins University Applied Physics Laboratory cheer as they receive confirmation of DART’s collision with the asteroid Dimorphos—the world’s first planetary defense technology demonstration. During the spacecraft’s final moments before impact, its Didymos Reconnaissance and Asteroid Camera for Optical navigation imager took four images capturing its terminal approach as Dimorphos increasingly fills the field of view. The investigation team will now observe Dimorphos using ground-based telescopes to confirm that DART’s impact altered the asteroid’s orbit around Didymos. Researchers expect the impact to shorten Dimorphos’ orbit by about 1%, or roughly 10 minutes; precisely measuring how much the asteroid was deflected is one of the primary…

Technicians prepare to move NASA’s Double Asteroid Redirection Test (DART) spacecraft from a shipping container onto a work stand inside the Astrotech Space Operations Facility at Vandenberg Space Force Base in California in this image from Oct. 4, 2021. DART was launched on Nov. 23, 2021, aboard a SpaceX Falcon 9 rocket from Vandenberg. The spacecraft will intentionally smash into the moonlet Didymos on Sept. 26, 2022, to see if this method of asteroid deflection—known as the kinetic impactor technique—would be a viable way to protect our planet if an asteroid on a collision course with Earth were discovered in the future.

约翰·w·杨在月球向美国国旗致敬

ByNASA中文 2022年9月26日2022年9月26日

Astronaut John W. Young, commander of the Apollo 16 lunar landing mission, leaps from the Moon’s surface as he salutes the United States flag at the Descartes landing site during the first Apollo 16 spacewalk. Astronaut Charles M. Duke Jr., lunar module pilot, took this picture on April 21, 1972. The Lunar Module Orion is on the left and beside it is the Lunar Roving Vehicle. Behind Young, in the shadow of Orion, is the Far Ultraviolet Camera/Spectrograph. Young and Duke conducted three surface excursions totaling more than 20 hours, using the Lunar Roving Vehicle for transportation. They deployed an experiment package, collected 209 pounds of rock and soil samples, and set up the first telescope on the Moon.

Our Shuttle Carrier Aircraft ferries the Space Shuttle Endeavour over the Johnson Space Center in Houston in this Sept. 20, 2012, image. Endeavour’s end destination was the California Science Center, where it sits on display. The shuttle Endeavour brought the first parts of the International Space Station to space and completed 25 missions. On its final flight to the California Science Center 10 years ago, Endeavour was escorted by a combination of F/A-18s and an F-15 from NASA’s Armstrong Flight Research Center in Edwards, California. Those aircraft were flown by NASA Armstrong pilots, while center photographers and videographers documented the orbiter’s final journey.
