SpaceX Crew-8 astronauts splash down after weather delays

(NASA)

SpaceX Crew-8 astronauts Matthew Dominick, Michael Barratt and Jeanette Epps all with NASA and Roscosmos cosmonaut Alexander Grebenkin splashed down in the Gulf of Mexico off the coast of Pensacola, Florida on Friday (Oct. 25) at 3:29 a.m. EDT (0729 GMT). Their landing after 235 days - including a more than two-week wait on board the International Space Station (ISS) for acceptable conditions -- set a record for their spacecraft.

Astra gets up to $44 million for new 'Rocket 4' line

(Astra)

Astra just got some help in getting its new rocket off the ground. The California-based company announced today (Oct. 23) that it has signed a contract with the Defense Innovation Unit (DIU), a U.S. military organization that focuses on adopting and adapting commercial technologies. The deal, worth up to $44 million, "supports advancing and scaling the production capabilities of Astra's unique tactically responsive launch system, to achieve the prototype objective of launching Rocket 4 to orbit or suborbit and from the U.S., Australia, or other locations," Astra wrote in a statement.

Sun erupts in 1st images from groundbreaking new satellite

(NOAA/NASA)

The first images from a new space-based telescope launched into Earth's orbit to monitor the sun captured a striking solar storm outburst. The National Oceanic and Atmospheric Administration (NOAA) shared the first images taken by its Compact Coronagraph (CCOR-1), the world's first operational space-based coronagraph. CCOR-1 is mounted on NOAA's newest geostationary satellite, GOES-19, which launched into orbit above Earth on June 25.

One of the largest carbon-based space molecules ever

(NASA/JPL-Caltech/STScI)

Astronomers have discovered one of the largest carbon-based molecules found in deep space, located within the Taurus molecular cloud, 430 light-years from Earth. The finding is significant because it provides further clues that might help solve a longstanding mystery in astrochemistry: Where does carbon, the building block of life, come from?

SpaceX's workhorse Falcon 9 rocket just hit the century mark for the year. A Falcon 9 launched a batch of next-gen spy satellites for the U.S. National Reconnaissance Office (NRO) today (Oct. 24) from California's Vandenberg Space Force Base at 1:13 p.m. EDT (1713 GMT; 10:13 a.m. local time). The clandestine mission, known as NROL-167, was the 100th Falcon 9 liftoff of 2024.

She's the most enthusiastic crewmember on board the USS Cerritos but science officer Lieutenant D'Vana Tendi grew up in a very different environment to the Federation. She hails from the fifth biggest pirate clan in the Orion Syndicate, and - after the events of the "Lower Decks" season 4 finale - she's reluctantly returned to the family business.

Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 25.10 в 11:30 будут заслушаны
2 доклада:

1). А. Д. Долгов коллоквиум
Первичные черные дыры, темная материя и антиматерия в пост-инфляционной
Вселенной

Показано, что космологические проблемы, обнаруженные как в современной,
z = 0, так и в ранней Вселенной, z ∼ 10, успешно решаются, если
зародышами космических структур являются массивные и сверх-массивные
первичные черные дыры. Обсуждается необходимость инфляции при создании
таких черных дыр. В пользу справедливости модели говорит согласие
предсказанного спектра масс первичных черных дыр с наблюдениями, а также
наблюдения в нашей Галактике значительного количества антиматерии:
позитронов, антиядер и антизвезд.

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

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.

Crew-8 astronauts undock from ISS after weather delays

(NASA)

SpaceX's Crew-8 quartet of astronauts departed the space station at last yesterday, following more than two weeks of weather-related delays. The Dragon spacecraft for SpaceX Crew-8 undocked from the ISS at 5:05 p.m. EDT (2105 GMT),f is expected to splash down off the coast of Florida around 3:30 a.m. EDT (0730 GMT) on Friday (Oct. 25). NASA will livestream the splashdown on NASA+, with a post-splashdown news conference is planned for later that morning.

Watch sun unleash major X-flare in epic solar eruption

(SDO/HMI, created in Canva by Daisy Dobrijevic)

The sun has been rather quiet of late but has since roared back to life with a major X-class solar flare eruption, the most powerful class of solar flare. The intense solar flare originated from sunspot region AR3869 and unfolded over the span of an hour, reaching its peak at 11:57 p.m. EDT on Oct. 23 (0357 GMT on Oct. 24). Extreme ultraviolet radiation from the eruption triggered shortwave radio blackouts over Australia and Southeast Asia.

Fireball blazes across Lake Erie a week before Halloween

(Paul M.)

On Monday (Oct. 21) night, a bright fireball could be seen streaking across the skies over Lake Erie in the U.S. and Canada. Over 550 witness reports of the meteor were submitted to the American Meteor Society's (AMS) "Report a Fireball" webpage; the object could be tracked moving from northeast of Cleveland, Ohio, to just west of Erie, Pennsylvania. The event occurred around 7:00 p.m. EDT (2300 GMT) on Oct. 21. Accounts of the fireball came from viewers as far east as Philadelphia, Pennsylvania and as far south as Madison, North Carolina - nearly 400 miles (640 kilometers) away.

British startup plans to supply solar power from space to Icelanders by 2030, in what could be the world's first demonstration of this novel renewable energy source. The space solar power project, announced on Monday (Oct. 21), is a partnership between U.K.-based Space Solar, Reykjavik Energy and Icelandic sustainability initiative Transition Labs. It intends to launch a demonstrator satellite by 2030, which will beam to Earth 30 megawatts of clean energy - enough to power about 3,000 homes.
