The South Atlantic Anomaly (SAA) has become a subject of intense study, drawing attention from scientists and space agencies around the globe. This region, characterized by a unique weakening of Earth's magnetic field, poses significant challenges, particularly for space technology. The anomaly, situated over South America and the South Atlantic Ocean, is a natural phenomenon with potential consequences for satellites and spacecraft. Understanding the origins and implications of the SAA is crucial as it evolves, demanding innovative solutions to safeguard technological infrastructure and enhance our comprehension of planetary dynamics. Deep Origins and Complex Mechanisms
The South Atlantic Anomaly (SAA) represents a significant reduction in magnetic intensity, creating a breach in Earth's protective shield. This allows high-energy solar particles to come perilously close to the planet's surface. The origins of the SAA are linked to complex processes within Earth's outer core, known as the geodynamo. Here, the motion of molten iron and nickel generates Earth's magnetic field, although not uniformly.
Two primary factors contribute to the SAA: the tilt of Earth's magnetic axis relative to its rotational axis and the influence of a dense structure deep beneath Africa, known as the African Large Low Shear Velocity Province. These elements disrupt magnetic field generation, resulting in a local polarity reversal and a weakened magnetic intensity in this region. This intricate interplay underscores the critical need for ongoing research to unravel the SAA's mysteries and anticipate its future impact.

The SAA poses notable risks to space technology, as satellites passing through the region encounter elevated levels of energetic protons. These particles can cause single event upsets (SEUs), leading to temporary malfunctions, data corruption, or even permanent damage if critical systems are compromised. To mitigate these risks, satellite operators adopt precautionary measures, such as shutting down non-essential systems during SAA transits.
The International Space Station (ISS) also crosses the SAA, exposing its external instruments to potential vulnerabilities. While astronauts are shielded, instruments like the GEDI experience occasional glitches, resulting in data loss. Missions like the Ionospheric Connection Explorer (ICON) closely monitor the SAA, adjusting operations to minimize disruptions. Understanding the SAA's impact on space technology remains vital for ensuring the reliability and longevity of orbiting infrastructure.

Patrick Star and 'Drag Queen' crab: underwater robot live stream captivates Argentines
The Argentine-American scientific mission is for the first time exploring the Mar del Plata canyon, a submarine gorge which plunges nearly 4,000 meters (13,000 feet) deep, off the coast of the seaside resort of the same name. The awed conversations between scientists leading the expedition and the explanations they give to viewers allow the public a rare insight into the hidden wonders of marine biology. In one instance, the camera on the SuBastian underwater robot shows a weird-looking, little white animal. One of the scientists on the team can be heard asking her colleagues, "Do we want it?" "Yes, yes, we want it!" reply dozens of messages in the live stream chat before the image shows the suction device being activated to suck up the specimen for study. "Oh, I love these little creatures," says one user. "I'm obsessed!" comments another. "Don't take the little one away!" pleads a third. The live stream began a week ago and exceeded one million views per day since Thursday, when it also began to be broadcast on television. "There are cold-water corals with the same colors as those in the Caribbean. How can that be? At a depth of 3,000 meters!" Pablo Penchaszadeh, a marine biologist and painter who is on board the expedition as an artist, told AFP. Patrick Star The 20-day expedition "Underwater Oases of the Mar del Plata Canyon" involves 25 scientists -- most of them from the Argentine research agency CONICET. Part of the GEMPA deep sea study group, with support from the US Schmidt Ocean Institute, it will end on August 10. Aboard the Schmidt Ocean Institute's "Falkor (too)" ship, scientists remotely operate the robot, which can descend to a depth of 4,500 meters (14,700 feet). They collect biological samples with its robotic arms and other instruments, and send back high-definition images. "The fact that anyone can connect from home and see what we are seeing live is a unique opportunity," explains expedition leader Daniel Lauretta in a statement. "Science is no longer something distant or inaccessible, but becomes part of everyday life." This week, social media users were delighted when an orange starfish with two symmetrical bumps resembling buttocks appeared on the live stream. It quickly prompted comparisons with Patrick Star, from the popular animated series SpongeBob SquarePants. Memes circulated joking that "Patrick is Argentine," marine biology became a trending topic on social media, and the broadcast reached the screens of hundreds of thousands of captivated viewers. "I came to see the big-bottomed star, is it here?" asked one user upon entering the YouTube chat. Spectators also gave other sea creatures nicknames: a king crab was dubbed "Drag Queen," and sea cucumber was fondly called "Sweet Potato." 'Beacon of light' This is the first time that human eyes -- albeit remotely -- have seen this underwater oasis in real time, where the cold, nutrient-rich Malvinas current and warm, salty Brazil current converge. The confluence is "one of the most energetic regions in our global Ocean," according to the website of the Schmidt Institute, with the temperature difference creating an area teeming with marine wildlife and flora. "We are already seeing incredible things: animals that have never been recorded in this area, underwater landscapes that look like something from another planet, and behaviors that surprise even the most experienced scientists," said Lauretta. But funding for such expeditions is under threat in Argentina. CONICET, the government's scientific research arm, has been severely underfunded by libertarian President Javier Milei, who has implemented draconian cuts to public spending with his infamous "chainsaw." Its budget fell by 21 percent last year, salaries have plummeted by 35 percent since the Milei took office in December 2023, and the cuts have led to an exodus of scientists. As a result, in between "oohs" and "aahs" of wonder, messages of support are flooding the live stream's chat: "Long live Conicet!". "Seeing people being passionate about their job is attractive," said Tomas Atilio Luppi, a biologist at the CONICET-affiliated marine and coastal research institute in Mar del Plata, who is not directly involved in the campaign. "This is happening at a very difficult time," he told AFP of the popular broadcast. "Science is in a very complicated position, both financially and in terms of support and human resources." "The fact that this craze is happening is like a beacon of light."

SpaceX delivers four astronauts to the International Space Station
A new crew was delivered to the International Space Station (ISS) by SpaceX on Saturday, who made the trip in only 15 hours. Four US, Russian and Japanese astronauts pulled up in the SpaceX ship after launching from NASA's Kennedy Space Centre. They will spend at least six months in station orbiting Earth. Their flight had been delayed by one day due to bad weather. The four moving into the ISS are NASA's Zena Cardman and Mike Fincke, Japan's Kimiya Yui and Russia's Oleg Platonov. 'Hello, space station!' Fincke radioed as soon as the capsule docked. Cardman and another astronaut were pulled from a SpaceX flight last year to make room for NASA's two stuck astronauts, Boeing Starliner test pilots Butch Wilmore and Suni Williams. Their space station stay went from one week to more than nine months due to a faulty Boeing spacecraft. Fincke and Yui had been training for the next Starliner mission. However, with Starliner grounded by thruster and other problems until 2026, the two switched to SpaceX. Platonov was bumped from the Soyuz launch line-up several ago because of an undisclosed illness. The arrival of the astronauts on Saturday temporarily puts the ISS population at 11. The astronauts greeting them had cold drinks and hot food waiting for them The arriving astronauts will replace four colleagues who have already been in the ISS since March. Those four will be brought back as early as Wednesday. While Saturday's arrival was speed by US standards, Russia holds the record for the fastest trip to the ISS at three hours.
