'NASA at a crossroads:' Budget woes, hard choices ahead

(NASA)

The next few years are likely to be pivotal ones for NASA, according to a hard-hitting report by the U.S. National Academies of Sciences, Engineering, and Medicine. The report, which was released last month, is called "NASA at a Crossroads: Maintaining Workforce, Infrastructure and Technology Preeminence in the Coming Decades." And that title was chosen advisedly.

Exclusive: Doritos' 1st ad in space with 'zero-g' chips

(Polaris Dawn)

Doritos has released its first ad filmed in space, and it is filled with the sound of astronauts "crunching" down on the brand's first-ever chips to leave the planet.

Comet Tsuchinshan-ATLAS lights up night sky in livestream

(Space.com / Josh Dinner)

Comet C/2023 A3 (Tsuchinshan-ATLAS) is still visible in the night sky, and you can watch it live today thanks to a free livestream. Comet Tsuchinshan-ATLAS is growing dimmer as it speeds away from Earth. It should be visible through at least Saturday (Oct. 26), but the comet is speeding away from Earth and growing more difficult to see with the naked eye. The comet is currently high in the west at sunset as seen from the mid-latitudes of North America, but is dim enough that a pair of binoculars or small telescope is likely your best bet at this point.

Most of Earth's meteorites may come from the same 3 spots

(Costfoto/Future Publishing via Getty Images)

Scientists know that the vast majority of meteorites that come crashing down to Earth originate from the solar system's main asteroid belt: a region between Mars and Jupiter where irregularly shaped rocks left over from the formation of the solar system crash into and bounce off each other during their journeys around the sun. In new research, however, an international team of scientists are claiming to have identified three young, distinct asteroid families in the main asteroid belt as the source of 70% of Earth's meteorites. "Asteroid families" refer to a population of asteroids, which could be composed of a handful or hundreds of fragments that likely originate from a past asteroid collision.

SpaceX launches 20 Eutelsat OneWeb broadband satellites

(SpaceX)

SpaceX launched the last batch of Eutelsat OneWeb's V1 satellites from California's Vandenberg Space Force Base atop a Falcon 9 rocket on Sunday at 1:13 a.m. EDT (0513 GMT; 10:13 p.m. on Oct. 19 local California time). The Falcon 9's first stage returned to Earth as planned, touching down at Vandenberg's Landing Zone 4 about eight minutes after lifting off. It was the seventh launch and landing for this particular booste

Nancy Roman Space Telescope aces crucial 'spin test'

(NASA/Chris Gunn)

NASA recently put a crucial part of the Roman Space Telescope - the Outer Barrel Assembly -- through a rigorous "spin test" designed to evaluate its resilience against the intense gravitational forces it will encounter during launch. This test, a standard procedure in aerospace engineering, typically takes place inside a massive centrifuge that mimics the elevated gravity conditions of a space mission.

Neil deGrasse Tyson's 1st book remains 'deeply charming' (exclusive)

(Blackstone Publishing)

As a celebrity astrophysicist and witty host of StarTalk, Neil deGrasse Tyson has penned dozens of books over the years, but as they say, you never forget your first. That designation belongs to an amusing volume compiled in 1989 when Tyson was a graduate student at Columbia University, titled "Merlin's Tour of the Universe." It's a collection of over 200 questions posed to him by the general public for a column he wrote in the StarDate newsletter for The McDonald Observatory of West Texas. These varied queries ranged in topics from astronomy and planetary science, to gravity, black holes, and time travel that the young 20-something scientist would answer through the persona of an intergalactic sage named Merlin.

Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 25.10 в 11:30 будут заслушаны 2 доклада:
1). А. Д. Долгов
TBA

2). Борис Семисалов (ИМ СО РАН, Новосибирск)
Моделирование волновой кинетики бозе-газа (по материалам докторской диссертации)

Выявление механизмов зарождения и развития турбулентных течений в жидкостях, газах и плазме является одной из открытых проблем современной физики. Использование здесь математических методов позволяет описать процессы передачи энергии и других инвариантов между разномасштабными возмущениями, а также исследовать различные режимы эволюции спектров инвариантов. Такие исследования опираются на применение теории волновой (слабой) турбулентности, основным объектом которой является кинетическое уравнение (КУ), описывающее взаимодействия волн в нелинейных гамильтоновых физических системах.

В докладе приводится краткая сводка последних исследований четырёхволнового КУ, полученного из уравнения Гросса–Питаевского и описывающего однородные изотропные взаимодействия волн в бозе-газе. Дано сравнение спектров динамического и кинетического уравнений на больших временных интервалах. Найдены точные стационарные решения КУ типа спектров Колмогорова–Захарова с логарифмической поправкой, описывающие прямой каскад энергии и обратный каскад частиц бозе-газа. Численно исследованы автомодельные режимы эволюции спектров первого и второго рода. Результаты моделирования сопоставлены с данными экспериментов.

Представленные результаты получены в соавторстве с
Назаренко С.В., Zhu Y., Krstulovic G., Гребенёвым В.Н., Медведевым С.Б.

ID и пароль онлайн-трансляций в Zoom те же, что и для предыдущих трансляций семинаров и докладов на Ученом совете:

При числе желающих не менее 5 будет организован автобус.
Для записи на автобус из Москвы в Черноголовку необходимо до 18:00 четверга отправить письмо на адрес электронной почты bus@itp.ac.ru
После этого записавшимся до 20:00 поступит подтверждение об отправке или неотправке автобуса в зависимости от числа записавшихся.
Запись на обратный автобус - на Ученом совете.

Inflatable habitats could be key to exploring space

(Max Space)

It's high time to crank up the volume in space! That's the shout from several private firms that want to see an inflation factor for the future. What is now being evaluated and tested is the use of "softgoods" to fashion inflatable/expandable airlocks and off-Earth habitats, not only for low Earth orbit, but also to provide comfy housing for future moon and Mars explorers.
