Li) Euclid telescope discovers stunning Einstein ring The Euclid space telescope has, by chance, discovered its first Einstein ring, and it is absolutely stunning. Beyond its aesthetic appeal, this perfectly circular Einstein ring has allowed researchers to "weigh" the dark matter at the heart of a galaxy almost 600 million light-years away.

IM-2, the second moon mission by Houston company Intuitive Machines, will lift off from Florida's Space Coast during a four-day window that opens on Feb. 26. If all goes to plan, Athena will land on a plateau just 100 miles (160 kilometers) from the moon's south pole. This region is thought to be rich in water ice, and IM-2 will prospect for the precious resource with the help of some ride-along robots, including a pioneering hopper nicknamed Gracie.

The XB-1 broke the sound barrier three times during its 13th and final test flight, which lifted off Monday from the Mojave Air & Space Port in southeastern California. Watch replay On This Day in Space Feb. 11, 2010: NASA launches Solar Dynamics Observatory (NASA) On Feb. 11, 2010, NASA launched a spacecraft to study the inner workings of the sun. The new Solar Dynamics Observatory was made to take the most detailed and comprehensive measurements of the sun ever. The satellite orbits Earth, but its orbit allows it to look at the sun continuously. It looks for activity like sunspots and solar flares, but it also studies the sun's magnetic field. By better understanding the sun's crazy and warped magnetic fields, scientists hope to better predict space weather events that spew harmful radiation toward Earth. The Solar Dynamics Observatory launched just in time to see the sun during the peak of its 11-year solar cycle.

Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 14.02 в 11:30 будет заслушан 1 доклад:
1). А.В. Ланкин, Г.Э. Норман
Новое направление квантовых технологий (Постулат фон Неймана для коллапса волновой функции: экспериментальная верификация и обобщение. Квантовая нелокальность. Контрафактная передача информации.)

Сделан обзор базовых работ по понятию измерения в квантовой механике от
теоретических (Борн 1926, фон Нейман 1932, Дике 1981, Леггетт и Гарг 1985) до
экспериментальных, верифицирующих теорию (квантовый эффект Зенона 1990,
контрафактная связь 2017, неравенства Леггетта-Гарга 2024). Проведено
обобщение постулата фон Неймана на interaction-free измерения одночастичных
состояний. В рамках единого подхода рассмотрены разнородные задачи
(контрафактные процедуры, неравенства Леггетта-Гарга). Сделана попытка дать
формулировку квантовой механики как физической теории, постулаты которой
включают: для однократных измерений – постулат Борна, для многократных –
постулат фон Неймана и его обобщение для interaction-free измерений. Показано
снижение энергозатрат на передачу одного бита при контрафактной передаче
информации, по сравнению с классическим пределом. Из проведенного
рассмотрения следует нелокальность квантовой механики даже для
одночастичных состояний, когда отсутствуют квантовые корреляции. Рассмотрены
перспективы приложений, которые связаны с interaction-free измерениями, т.е.
коллапсом волновой функции без взаимодействия.

План выступления:
1. Постулаты Борна (1926) и фон Неймана (1932)
2. Квантовый эффект Зенона (1990)
3. Interaction-free измерения (Дике 1981, Леггетт и Гарг 1985)
4. Обобщение постулата фон Неймана на interaction-free измерения
одночастичных состояний.
5. Неравенства Леггетта-Гарга.
6. Протокол контрафактных измерений.
7. Контрафактная передача информации (без передачи материи и/или энергии).
8. Выводы.

Odds of an asteroid impact in 2032 just went up. Here's why experts say you shouldn't worry

2032 asteroid impact chances just went up, but don't worry | Space Quiz! What region of the moon is believed to be rich in water ice? | This Week In Space: Episode 147 - Not As They Seem Created for znamenski.spacecom@blogger.com |  Web Version February 10, 2025 CONNECT WITH SPACE.COM       Something amazing every day. SIGN UP ⋅   WEBSITE The Launchpad (Robert Lea (created with Canva)) 2032 asteroid impact chances just went up, but don't worry The odds of the asteroid 2024 YR4 impacting Earth in 2032 have increased to 1 in 43. Despite this, you still shouldn't worry about the potential impact of this asteroid. That's because experts expected the impact probability of this asteroid, which sits at the top of the Center for Near Earth Object Studies Sentry asteroid risk list, to increase. They also expect the chance of an impact to fall dramatically in the near future when we know more about its orbit. Click for peace of mind Space Quiz!

North Pole Equator Far side South Pole (TWiS) This Week In Space: Episode 147 - Not As They Seem On Episode 147 of This Week In Space, Rod Pyle and Tariq Malik speak with Mick West, a passionate conspiracy debunker who, rather uniquely, proceeds with kindness and empathy as he unravels some of the key pseudoscience of our time. Listen now Spaceflight (Rocket Lab) Rocket Lab launches 'Internet of Things' satellites A 59-foot-tall (18 meters) Electron rocket carrying five spacecraft for the French company Kinéis lifted off from Rocket Lab's New Zealand site at 3:43 p.m. EST (2043 GMT; 9:43 a.m. Feb. 9 local New Zealand time). The launch was the fourth of five that Rocket Lab is conducting to build out Kinéis' 25-nanosatellite constellation in low Earth orbit. Read More SpaceX (SpaceX) SpaceX launches 21 Starlink satellites from Florida (video) SpaceX launched another batch of its Starlink internet satellites from Florida's Space Coast on Saturday (Feb. 8). A Falcon 9 rocket carrying 21 Starlink spacecraft, including 13 with direct-to-cell capability, lifted off from Cape Canaveral Space Force Station Saturday, at 2:18 p.m. EST (1918 GMT). Read More Technology (General Atomics) NASA and General Atomics test future nuclear fuels The first humans to Mars might someday ride a rocket propelled by a nuclear reactor to their destination. But before that can happen, nuclear thermal propulsion technologies still have quite a way to go before we could blast astronauts through space on a nuclear rocket. Earlier this month, though, General Atomics Electromagnetic Systems tested a new NTP reactor fuel at NASA's Marshall Space Flight Center in Alabama, to find out if the fuel could function in the extreme conditions of space. Read More Entertainment (Bandai Namco / Legendary) Live-action 'Gundam' movie enters full production Thundering confidently into production this past week, Bandai Namco and Legendary's big-budget live-action "Gundam" movie is already assembling with recent news of the start of filming. This "Mobile Suit Gundam" project based on the insanely popular toy and anime line was originally revealed back in 2018, with Brian K. Vaughn reportedly set to write the script. It's been mostly radio silence ever since and fans were beginning to seriously doubt whether it would ever suit up for the silver screen. Read More On This Day in Space (JAXA/NASA/Hinode)) Feb. 10, 1958: Radar bounced off Venus by MIT On Feb. 10, 1958, scientists at MIT's Lincoln Laboratory bounced radar waves off of Venus. At the time, Venus was at a point in its orbit called inferior conjunction, where it is directly in between the Earth and the sun. Scientists beamed a radar signal toward Venus, which was about 28 million miles away at the time. It took about 5 minutes for the signal to bounce off of Venus and return to Earth. This was slightly shorter than they anticipated, which means that Venus was actually closer to Earth than scientists believed at the time.
