Preparations for Next Moonwalk Simulations Underway (and Underwater)

A 3D simulation showing the evolution of turbulent flows in the upper layers of the Sun. The more saturated and bright reds represent the most vigorous upward or downward twisting motions. Clear areas represent areas where there is only relatively slow up-flows, with very little twisting.NASA/Irina Kitiashvili and Timothy A. Sandstrom NASA supercomputers are shedding light on what causes some of the Sun’s most complex behaviors. Using data from the suite of active Sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar dynamics like never before.
The animation shows the strength of the turbulent motions of the Sun’s inner layers as materials twist into its atmosphere, resembling a roiling pot of boiling water or a flurry of schooling fish sending material bubbling up to the surface or diving it further down below.
“Our simulations use what we call a realistic approach, which means we include as much as we know to-date about solar plasma to reproduce different phenomena observed with NASA space missions,” said Irina Kitiashvili, a scientist at NASA’s Ames Research Center in California’s Silicon Valley who helped lead the study.
Using modern computational capabilities, the team was able, for the first time to reproduce the fine structures of the subsurface layer observed with NASA’s Solar Dynamics Observatory.
“Right now, we don’t have the computational capabilities to create realistic global models of the entire Sun due to the complexity,” said Kitiashvili. “Therefore, we create models of smaller areas or layers, which can show us structures of the solar surface and atmosphere – like shock waves or tornado-like features measuring only a few miles in size; that’s much finer detail than any one spacecraft can resolve.”
Scientists seek to better understand the Sun and what phenomena drive the patterns of its activity. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts, auroras and many other phenomena. Space weather predictions are critical for exploration of space, supporting the spacecraft and astronauts of NASA’s Artemis campaign. Surveying this space environment is a vital part of understanding and mitigating astronaut exposure to space radiation and keeping our spacecraft and instruments safe.
This has been a big year for our special star, studded with events like the annular eclipse, a total eclipse, and the Sun reaching its solar maximum period. In December 2024, NASA’s Parker Solar Probe mission – which is helping researchers to understand space weather right at the source – will make its closest-ever approach to the Sun and beat its own record of being the closest human-made object to reach the Sun.
The Sun keeps surprising us. We are looking forward to seeing what kind of exciting events will be organized by the Sun."

NASA Scientist
“The Sun keeps surprising us,” said Kitiashvili. “We are looking forward to seeing what kind of exciting events will be organized by the Sun.”
These simulations were run on the Pleaides supercomputer at the NASA Advanced Supercomputing facility at NASA Ames over several weeks of runtime, generating terabytes of data.
NASA is showcasing 29 of the agency’s computational achievements at SC24, the international supercomputing conference, Nov. 17-22, 2023, in Atlanta, Georgia. For more technical information, visit:

The unpiloted Roscosmos Progress spacecraft pictured on Feb. 7, 2023, from the International Space Station.Credit: NASA NASA will provide live launch and docking coverage of a Roscosmos cargo spacecraft delivering nearly three tons of food, fuel, and supplies to the Expedition 72 crew aboard the International Space Station.
The unpiloted Progress 90 spacecraft is scheduled to launch at 7:22 a.m. EST (5:22 p.m. Baikonur time) Thursday, Nov. 21, on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan.
Live launch coverage will begin at 7 a.m. on NASA+ and the agency’s website. Learn how to watch NASA content through a variety of platforms, including social media.
After a two-day in-orbit journey to the station, the spacecraft will dock autonomously to the space-facing port of the orbiting laboratory’s Poisk module at 9:35 a.m., Saturday, Nov. 23. NASA’s coverage of rendezvous and docking will begin at 8:45 a.m. on NASA+ and the agency’s website.
The Progress 88 spacecraft will undock from the Poisk module on Tuesday, Nov. 19. NASA will not stream undocking.
The spacecraft will remain docked at the station for approximately six months before departing for a re-entry into Earth’s atmosphere to dispose of trash loaded by the crew.
The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For more than 24 years, NASA has supported a continuous U.S. human presence aboard the orbiting laboratory, through which astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including missions to the Moon under Artemis and, ultimately, human exploration of Mars.

SpaceX NASA and SpaceX are targeting no earlier than 7:05 a.m. EDT Sunday, Oct. 13, for the agency’s SpaceX Crew-8 mission to undock from the International Space Station. Pending weather conditions, the earliest splashdown time is targeted for 3:38 p.m. Monday, Oct. 14, at one of the multiple zones available off the coast of Florida.
NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, and Roscosmos cosmonaut Alexander Grebenkin, are completing a seven-month science expedition aboard the orbiting laboratory and will return important and time-sensitive research to Earth.
Mission managers continue monitoring weather conditions in the area, as Dragon’s undocking depends on various factors, including spacecraft readiness, recovery team readiness, weather, sea states, and other factors. NASA will select a specific splashdown time and location closer to the Crew-8 spacecraft undocking.
