SIGN UP ⋅   WEBSITE   The Launchpad Boeing Space & Defense chief Ted Colbert is leaving: reports (NASA) Boeing is getting a new space chief. Ted Colbert will no longer be CEO of Boeing Defense, Space & Security, one of the aerospace giant's subdivisions, according to media reports. Those reports cite a staff memo circulated today (Sept. 20) by Boeing CEO Kelly Ortberg, who took the top job in August. Full Story: Space (9/20)  Space Quiz! Why are we unable to view all of the universe with our eyes? Learn the answer here! It's too far away It's too old Our eyes can't see parts of the electromagnetic spectrum Earth is too small This Week In Space podcast: Episode 129 - Back From Mars! (TWiS) On Episode 129 of This Week In Space, Rod Pyle and Tariq Malik talk with Dr. Pascal Lee about his Mars Simulation Base in the Arctic. Devon Island, a polar desert in the High Arctic, is one of the most convincing Mars analogs on Earth. That's why Pascal Lee built his NASA-affiliated research base there. On this episode he returns to discuss his summer field work, Martian volcanoes, and to discuss possible alternatives to NASA's plans for the Artemis lunar base.There's a lot to know, and he brings deep passion--and some controversy--to the conversation!

Full Story: Space (8/7)  Spaceflight NASA astronaut, 2 cosmonauts return to Earth today (Sep 23) (NASA) A NASA astronaut and two record-setting Russian cosmonauts are set to head back to Earth on Monday (Sept. 23), and you can watch their homecoming live. Russia's Soyuz MS-25 spacecraft, with Tracy C. Dyson, Oleg Kononenko and Nikolai Chub aboard, is scheduled to undock from the International Space Station (ISS) on Monday at 4:37 a.m. EDT (0837 GMT) and land on the steppe of Kazakhstan about 3.5 hours later. Full Story: Space (9/22)  Science & Astronomy Massive radio survey reveals our universe's structure (MALS Team) When we look out into the universe with our unaided eyes, we are really only seeing a small chunk of what's actually there. That's because there are parts of the electromagnetic spectrum that our visual faculties are not sensitive to. Radiation is being emitted by all manner of cosmic phenomena across this spectrum, yet we're only able to physically see wavelengths within the visible light range without the help of external tools - but luckily, astronomers have access to telescopes that allow them to observe the universe across this continuum. Full Story: Space (9/23)  SpaceX Meet the SpaceX Crew-9 astronauts launching this week (NASA) Two astronauts are scheduled to launch to the International Space Station (ISS) next week, with two empty seats aboard their spacecraft. It's an atypical launch for a crewed SpaceX mission to the ISS, which customarily ferries four astronauts at a time. Originally, Crew-9 was slated to fly the usual four, but NASA astronauts Zena Cardman and Stephanie Wilson were removed from the flight when NASA made the decision to return Boeing's Starliner spacecraft without its crew, leaving astronauts Butch Wilmore and Suni Williams aboard the ISS in need of a ride home.

How is Canada preserving the few pieces of the aircraft that remain? Full Story: Space (9/22)  Search for Life What did China's Chang'e 6 lunar far side samples reveal? (CCTV) We finally have a glimpse of the first-ever samples collected from the far side of the moon. The first paper on the samples collected from China's Chang'e 6 lunar probe reveals that the specimens differ in some ways from those collected from the moon's near side. Thus, they could provide fresh insights and lead to new theories about the moon and its evolution.

Rocket Lab aborts launch of 5 'Internet of Things' satellites at last second (video)

Europa Clipper on track for Oct. 10 launch | Rocket Lab aborts launch of 5 'Internet of Things' satellites | The moon meets Seven Sisters of the Pleiades this weekend Created for znamenski.spacecom@blogger.com |  Web Version September 20, 2024 CONNECT WITH SPACE.COM       Something amazing every day. SIGN UP ⋅   WEBSITE   The Launchpad Europa Clipper on track for Oct. 10 launch (NASA/JPL-Caltech) Three weeks from now, NASA's Europa Clipper probe will lift off and embark on a long-awaited mission to study Jupiter's icy moon Europa, which scientists think is one of the most promising places to look for life beyond Earth. The launch appears to still be on track for Oct. 10, as per the agency's original schedule, which comes as a relief to scientists after the team discovered a few possibly defective transistors just months prior that threatened to imperil the mission. Full Story: Space (9/19)  Rocket Lab aborts launch of 5 'Internet of Things' satellites (Rocket Lab) Rocket Lab aborted a launch at the last second today (Sept. 18). The company's Electron rocket was scheduled to launch five "Internet of Things" satellites for the French company Kinéis today at 7 p.m. EDT (2300 GMT) from New Zealand. The countdown clock reached zero, and Electron appeared to fire up its first-stage engines. But they immediately shut down, resulting in an abort.

The company performed a "static fire" on Wednesday (Sept. 18) at its Starbase site in South Texas, briefly igniting the six Raptor engines of Ship 31, the upper stage of the vehicle that will conduct the sixth Starship test flight.

Уважаемые коллеги!

Завтра, в пятницу 20.09.2024 в 11:30 состоится коллоквиум, на котором
будет заслушан доклад:

Сергей Г. Тиходеев (МГУ и ИОФ им. А.М. Прохорова РАН)
*Поляритонная мультистабильность в хиральном полупроводниковом
микрорезонаторе
*
Фотонные резонансы в хиральных структурах приводят к большому количеству
интересных эффектов. Например, изготовление хирального фотонного
кристалла на верхнем зеркале полупроводникового микрорезонатора может
привести к тому, что его экситонная фотолюминесценция, как в спонтанном,
так и в лазерном режиме, может стать циркулярно-поляризованной [1,2]. С
другой стороны, нелинейность экситонного отклика при увеличении
интенсивности оптической накачки приводит к эффектам би- и
мультистабильности [3-5]. В докладе будет проанализирована
мультистабильность отклика экситон-поляритонов в хиральном
полупроводниковом микрорезонаторе. Будет показано, например, что даже
при линейно-поляризованной накачке и малой степени циркулярной
поляризации фотолюминесценции в спонтанном режиме, с ростом
интенсивности накачки в таких системах возможны резкие мультистабильные
переходы в состояния с высокой степенью циркулярной поляризации
фотолюминесценции.
