科学家们发现,两颗巨大的系外行星发生灾难性碰撞后产生的发光云团遮蔽了一颗恒星。
使用NASA的两台X射线望远镜,研究人员能够放大一颗死星释放出明亮、短暂的无线电波爆发时的不稳定行为。
The Orion spacecraft for NASA’s Artemis II mission received its latest makeover. Teams adhered the agency’s iconic “worm” logo and ESA (European Space Agency) insignia on the spacecraft’s crew module adapter on Sunday, Jan. 28, inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida. NASA/Rad Sinyak NASA’s iconic “worm” logo and ESA’s (European Space Agency) insignia are painted on the Orion spacecraft’s crew module adapter in this image from Feb. 1, 2024. The adapter houses electronic equipment for communications, power, and control, and includes an umbilical connector that bridges the electrical, data, and fluid systems between the main modules. In October 2023, technicians joined the crew and service modules together. The crew module will house the four Artemis II…
STS-60 commander Charles F. Bolden is seen at the commander’s station on the forward flight deck of the space shuttle Discovery. He is wearing the orange launch and entry suit. Bolden and his crewmates performed proximity operations with the Russian Mir space station. NASA Astronaut Charles F. Bolden, STS-60 commander, sits at the commander’s station on the forward flight deck of the space shuttle Discovery in this image from February 1994. While aboard Discovery, the crew attempted to deploy the Wake Shield Facility-1, a deployable/retrievable experiment platform designed to leave a vacuum wake in low earth orbit that is 10,000 times greater than achievable on Earth. The crew also conducted in-flight medical and radiological investigations and spoke with world leaders from space. Bolden was a…
“I have been interested in aviation for as long as I can remember. There are pictures of me at two years old and younger with my face pinned against the window, watching airplanes taxi around the airport. I had never not known that I wanted to be a pilot. The amazing engineering that goes into [airplanes], but certainly the freedom of flight is just spectacular. Being able to see the world from a different perspective is incredible, and getting to fly in space was the culmination of that, seeing the world from an entirely new vantage point. “One thing that surprised me was how emotional the launch piece is, especially for a first-time flier. One, it’s the culmination of these lifehood dreams where it’s taken…
The crewmen of the third and final manned Skylab mission relax on the USS New Orleans, prime recovery ship for their mission, about an hour after their Command Module splashed down at 10:17 a.m. (CDT), Feb. 8, 1974. The splashdown, which occurred 176 statute miles from San Diego, ended 84 record-setting days of flight activity aboard the Skylab space station cluster in Earth orbit. 1974年2月8日上午10点17分(美国中部时间),指挥舱溅落约一小时后,第三次也是最后一次载人天空实验室任务的机组人员在新奥尔良号航空母舰上休息。溅落发生在距离圣地亚哥176法定英里的地方,结束了在地球轨道上天空实验室空间站集群上84天创纪录的飞行活动。
NASA astronaut and Artemis II commander Reid Wiseman exits the side of a mockup of the Orion spacecraft during a training exercise in the Neutral Buoyancy Lab at NASA’s Johnson Space Center in Houston Jan. 23, 2024. As part of training for their mission around the Moon next year the crew of four astronauts practiced the recovery procedures they will use when the splash down in the Pacific Ocean. Artemis II is the first crewed mission on NASA’s path to establishing a long-term presence at the Moon for scientific discovery and exploration through the Artemis campaign. The approximately 10-day flight will test NASA’s foundational human deep space exploration capabilities, the SLS (Space Launch System) rocket and Orion spacecraft, for the first time with astronauts.

“[In] everyone’s life, they have a pivotal moment when they ask the question, ‘What am I really doing? What am I here for?’ … I’m reminded of a credo that I came up [with] through the evolution of my engagement of a whole bunch of recreational pursuits [including being a marathoner, ultrarunner, and Ironman triathlete] … as well as my professional pursuits. It’s threefold, and here’s what it is: “[First,] I’m here because I want to be able to challenge myself, to see how much I can squeeze out of me – whatever that is, whatever ‘me’ is. [For example,] I applied to the astronaut candidate program twice, but I failed to make it to the second round. I figured I’d give a go at…
