Alphonse Sterling (ST13) gave a lecture on solar physics to at a one-day school on 5/5/24, in Krakow, Poland. The lecture was entitled “Introduction to the Solar Interior and Atmosphere,” and was just given prior to the start of IAU Symposium 388 on Solar and Stellar Coronal Mass Ejections. The audience included students and postdocs from various international locations who were attending the Symposium.

Credit: NASA NASA released Tuesday the first episode of a new six-part podcast series for first-time space explorers to learn about the Sun. Ahead of the total solar eclipse in April, NASA’s Sun + Eclipse Series will focus on the sphere full of swirling magnetic fields and explosions of hot gases.
New episodes will post every Tuesday through April 23. The first episode is available at:
Sun Series: The Sun, Our Star – NASA
On April 8, 2024, a total solar eclipse will cross North America, passing over Mexico, the United States, and Canada. More than 32 million people will have the chance to witness, and a phenomenon the contiguous U.S. will not see again for 20 years.
The series will delve into the cultural connections and historical significance of solar studies. Listeners can prepare firsthand for the solar eclipse with insight from NASA experts along the path of totality. The series offers insight into research from NASA scientists, firsthand accounts from “eclipse chasers”, and how the agency protects astronauts and spacecraft during solar activity.
The series is part of NASA’s Curious Universe podcast. In each episode, hosts Padi Boyd and Jacob Pinter, bring listeners on science and space adventures. Explore the cosmos alongside astronauts, scientists, engineers, and other NASA experts in science, space exploration, and aeronautics.
NASA’s Sun + Eclipse Series is now available on Spotify, Apple Podcasts, Google Podcasts, and Soundcloud. Curious Universe is written and produced by a team at the agency’s Goddard Space Flight Center in Greenbelt, Maryland.

Full-duration RS-25 Engine Hot FireNASA/Danny Nowlin Full-duration RS-25 Engine Hot FireNASA/Danny Nowlin Full-duration RS-25 Engine Hot FireNASA/Danny Nowlin Full-duration RS-25 Engine Hot FireNASA/Danny Nowlin NASA conducted a full-duration RS-25 engine hot fire March 6, continuing a final round of certification testing for production of new engines to help power the SLS (Space Launch System) rocket on future Artemis missions to the Moon and beyond. The full-duration test on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, marked the ninth in a scheduled 12-test series. Engineers are collecting test data to certify an updated engine production process, using innovative manufacturing techniques, for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company. During the March 6 test, Operators fired the certification engine for 10 minutes (600 seconds), longer than the amount of time needed to help launch the SLS rocket and send astronauts aboard the Orion spacecraft into orbit. The test team also fired the engine at power levels between 80% and 113% to test performance in multiple scenarios. Four RS-25 engines, along with a pair of solid rocket boosters, launch NASA’s powerful SLS rocket, producing more than 8.8 million pounds of thrust at liftoff for Artemis missions. Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all. RS-25 tests at NASA Stennis are conducted by a diverse team of operators from NASA, Aerojet Rocketdyne, and Syncom Space Services, prime contractor for site facilities and operations.
