SIGN UP ⋅   WEBSITE   The Launchpad Crew-8 astronaut released from hospital, returns to Houston (NASA) The NASA astronaut who was hospitalized for a night after the splashdown of SpaceX's Crew-8 mission has been released and is doing well, according to the agency. The landing Friday morning (Oct. 25) went well, and everything appeared to be normal. However, shortly thereafter, NASA announced that all four Crew-8 astronauts -- NASA's Matthew Dominick, Michael Barratt and Jeanette Epps, and Alexander Grebenkin of Russia's space agency Roscosmos -- were taken to Ascension Sacred Heart Pensacola, a hospital in Florida, for evaluation. This was done "out of an abundance of caution," agency officials said in a post-splashdown news conference. Full Story: Space (10/28)  Space Quiz!

Ceres Saturn Vesta Psyche Starship booster was '1 second away' from tower catch abort (SpaceX) SpaceX's historic rocket catch earlier this month was even more dramatic than it looked. That catch occurred on Oct. 13, during the fifth test flight of SpaceX's Starship megarocket. Starship's huge first-stage booster, known as Super Heavy, came back to Earth about seven minutes after liftoff, nestling next to its launch tower, which secured the rocket with its "chopstick" arms. But that epic moment almost didn't happen: Super Heavy was just one second away from aborting the launch-tower landing and crashing into a patch of nearby ground, SpaceX engineers told company founder and CEO Elon Musk recently.

On Monday (Oct. 28), the comet evaporated as it was heading toward perihelion, the closest point to the sun in its orbit. There were earlier hopes that the comet, officially designated C/2024 S1 (ATLAS), could become a "Halloween treat" visible to the naked eye, but these were ultimately just wishful thinking; astronomers had already begun observing the cosmic snowball beginning to disintegrate earlier this month.

If all goes well during Artemis 2's planned September 2025 launch and round-the-moon mission, of course, the astronauts will keep all doors firmly shut. Conducting the first human lunar mission since Apollo 17 in 1972, however, requires a strict focus on safety - just in case.

Yes, it's back to that polarizing Prequel Era of "Star Wars," or to be exact, a storyline that spins out of events occurring right before those infamous Trade Federation Wars erupt and everybody got all riled up about a certain Podracing kid of destiny with a high midichlorian count living on Tatooine.

Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 01.11 в 11:30 будут заслушаны 2 доклада:
1). Г.С. Селезнев, Я. В. Фоминов
Влияние емкости и температурных флуктуаций на джозефсоновский диодный эффект в асимметричных СКВИДах с высшими джозефсоновскими гармониками

Асимметричные СКВИДы, в рукавах которых находятся разные джозефсоновские контакты с высшими джозефсоновскими гармониками в ток-фазовых соотношениях, демонстрируют (джозефсоновский) диодный эффект. Сила и знак эффекта зависят от магнитного потока через петлю интерферометра. Мы исследуем влияние конечной емкости контактов и температуры на различные проявления джозефсоновского диодного эффекта в асимметричном СКВИДе. Основное внимание уделяется «минимальной модели», в которой один контакт имеет синусоидальную ток-фазовую характеристику, а другой помимо этого имеет дополнительную вторую гармонику. Мы показываем, что наличие емкости контактов приводит к асимметрии гистерезисного поведения СКВИДа. В частности, оказывается возможным односторонний гистерезис (гистерезисное поведение только при одном направлении тока). В случае малой конечной температуры и нулевой емкости контактов мы определяем асимметрию вольт-амперной характеристики, которая в данном режиме оказывается экспоненциально сильной. В случае же конечной емкости контактов мы вычисляем асимметрию токов переключения как под действием температурных флуктуаций, так и в условиях синхронизации с внешним переменным током.
Доклад основан на работе Phys. Rev. B 110, 104508 (2024).

Фотоника: современное состояние по материалам конференции ALT во Владивостоке

23-27 сентября 2024 года проходила конференция ALT - Advanced Laser Technologies. Сайт конференции https://altconference24.ru/ Для выступлений использовались корпуса ДВФУ (Дальневосточный Федеральный Университет) на острове Русский. Рассмотрен широкий круг вопросов по лазерным технологиям от квантовых вычислений и биофотоники до плазмоники, сенсорам, ТГц и волоконной оптике. По итогам принято обращение к Президенту РАН Красникову Г.Я. В обращении подчеркивается важность направлений, связанных с фотоникой.
