Researchers from The Australian National University (ANU) have identified a doughnut-shaped structure deep within Earth's liquid core, offering new insights into the mechanisms behind our planet's magnetic field.
The newly discovered structure, located thousands of kilometers beneath the Earth's surface, is confined to low latitudes and aligns parallel to the equator. Despite its significa California lawmakers pass AI safety bill

A bill aimed at regulating powerful artificial intelligence models passed California's legislature on Wednesday, despite outcry that it could kill the technology it seeks to control.
"SB 1047 - our AI safety bill - just passed off the Assembly floor. I'm proud of the diverse coalition behind this bill - a coalition that deeply believes in both innovation and safety," said Democratic stat SpaceX Polaris Dawn mission set to launch early Friday

The SpaceX Polaris Dawn mission, a multiday orbital expedition set to feature the first-ever spacewalk by private citizens, is now scheduled to launch on Friday, according to the Federal Aviation Administration.
An operations plan released by the agency indicates a four-hour launch window opening at 3:33 am (0733 GMT) on Friday from NASA's Kennedy Space Center, with backup opportunities on Saturday and Sunday.

Juice's flight through Earth's radiation belts

During its recent flyby of Earth, ESA's Jupiter Icy Moons Explorer (Juice) travelled through the zones of charged particles that surround our planet. These two zones are known as the Van Allen radiation belts. The inner belt is mostly full of energetic protons, and the outer belt is mostly full of energetic electrons. The region between the two belts is mostly empty.
The high levels of radiation in the Van Allen belts makes them very dangerous for electronics and humans, but they pale in comparison to Jupiter's own radiation belts. At Jupiter, extremely energetic electrons can get through even the thickest of shielding, so they could damage Juice's scientific instruments over time.
Juice carries a radiation monitor called RADEM to continuously measure the spacecraft's exposure
NASA explains strange noise heard by astronaut in Boeing's Starliner

There's nothing to see here, or hear here, actually. That's the message NASA gave after reports of a strange noise heard by astronaut Butch Wilmore emanating from Boeing's Starliner docked to the International Space Station this weekend.
"A pulsing sound from a speaker in Boeing's Starliner spacecraft heard by NASA astronaut Butch Wilmore aboard the International Space Station has stopped," NASA posted to its social media accounts Monday.
It explained the mystery noise as feedback from the speaker that was the result of an audio configuration between the spacecraft and the ISS. Wilmore reported the sound as he was working inside Starliner on Saturday.
"The space station audio system is complex, allowing multiple spacecraft and modules to be interconnected, and it is common to experience noise and feedback," NASA stated. "The crew is asked to contact mission control when they hear sounds originating in the comm system."
NASA also took the opportunity to state the feedback has "no technical impact to the crew, Starliner, or station operations, including Starliner's uncrewed undocking from the station no earlier than Friday, Sept.

Vega for ESA: the story

Vega joined the family of launch vehicles at Europe’s Spaceport in French Guiana in 2012. At 30-m tall the rocket weighs 137 tonnes on the launch pad and reaches orbit with three solid-propellant powered stages before the fourth liquid-propellant stage takes over. By rocket standards Vega is lightweight and powerful, the first three stages burn through their fuel and bringing Vega and its satellites to space in just six minutes.
Specialising in launches of small satellites to orbits flying over Earth’s poles, Vega has an impressive roster of missions that it has sent to space. Flagship ESA missions

ESA is part of the Big Science Business Forum 2024 event on 1–4 October in Trieste, Italy. This is where industry and Europe’s leading science organisations, research infrastructures and their collaborators will meet to inform, network and discuss business opportunities in a market valued at nearly €10 billion annually.
