Ship-Signal Spoofing Spreads to Russia's Pacific Kozmino Port
The process, known as spoofing, sees signals sent between ships and the satellites used for global positioning systems swamped by false transmissions, which lead to vessels reporting themselves to be in impossible positions or moving at infeasible speeds.

The Race to Shrink Reactors and Grow Nuclear Power
Electricity demand is soaring, and some think the answer isn't building bigger, but smaller. That's the idea behind small modular reactors (SMRs): shrink a large and hard-to-build reactor to something that is, in theory, more manageable, cheaper and easier to replicate. These are early days for SMRs, with only two in commercial operation in Russia and China. Can SMRs ever become a solution for our energy needs and climate goals? Nuclear scientist and venture capitalist Rachel Slaybaugh joins Akshat Rathi on Zero to discuss.

Starlink Rival Announces Plans to Take on Musk With a $1.5 Billion Satellite Push
Texas startup AST SpaceMobile announced its plan to launch 45 to 60 satellites by 2026, establishing itself as a worthy competitor to SpaceX's Starlink constellation in building space-based broadband networks. The company announced its second-quarter earnings on Monday, revealing that it had $1.5 billion on its balance sheet to fund the deployment of dozens of its satellites, CNBC reported. The next day, AST SpaceMobile's shares soared by more than 10% with the prospect of the company providing coverage to the United States, as well as Europe, Japan, and other key markets. AST SpaceMobile launched its first satellite, BlueWalker 3, in September 2022 to test its long-term plan of establishing a space-based cellular broadband network directly accessible by cell phones. A year later, the company used its prototype satellite to carry out the first 5G phone call from space to a regular Samsung Galaxy S22. Since then, AST has launched five other satellites, named BlueBird, and it wants to send 243 more to orbit. In an effort to ramp up its orbital cell-phone towers, AST is aiming for four additional launches by the end of March 2026. 'We have planned orbital launches every one to two months on average during 2025 and 2026,' Abel Avellan, founder and CEO of AST SpaceMobile, said in a statement. With this substantial increase in pace, AST is chipping away at industry leader SpaceX. Naturally, the two companies are locked in a bickering match over who has the right to litter low Earth orbit with massive constellations. Last month, SpaceX sent a letter to the Federal Communications Commission to raise concern that AST SpaceMobile poses a threat to the sustainability of low Earth orbit. To be fair, the BlueWalker 3 was obnoxiously big, with a tennis court-sized array that stretched across 693 square feet after the satellite was fully unfurled. SpaceX's satellites, however, don't exactly get a good rep. Starlinks are known to interfere with astronomical observations of the cosmos despite some efforts by the company to mitigate the issue. Things are only going to get worse from here. SpaceX plans to deploy thousands more of its Starlink satellites, while AST's second-generation BlueBird satellites are three times larger than the first batch. There are other companies hoping to get in on the action as well, such as Amazon's Project Kuiper, which now has more than 100 satellites in orbit. Starlink may soon lose its monopolizing reign in low Earth orbit as more satellites fill up the skies.

Iconic Easter Island statues could be gone in 60 years, study warns
Easter Island's iconic moai statues face an existential threat from rising sea levels, with powerful seasonal waves predicted to inundate the 15 monumental figures at Ahu Tongariki by the end of the century, according to a new study. The research, published in the Journal of Cultural Heritage, also warns that approximately 50 other cultural sites on the remote Pacific island are at risk of flooding. "Sea level rise is real," stated Noah Paoa, lead author of the study and a doctoral student at the University of Hawaii at Manoa's School of Ocean and Earth Science and Technology. "It's not a distant threat." Mr Paoa, of Easter Island (known to its Indigenous people as Rapa Nui), and his team created a high-resolution "digital twin" of the island's eastern coastline, running computer models to simulate future wave impacts under various sea level rise scenarios. Their findings indicate that waves could reach Ahu Tongariki, the island's largest ceremonial platform, as early as 2080. This site, home to the towering moai, attracts tens of thousands of visitors annually and is crucial to the island's tourism economy. Beyond its economic value, the ahu is deeply intertwined with Rapa Nui's cultural identity, lying within Rapa Nui National Park, a recognized UNESCO World Heritage site. The roughly 900 moai statues across the island were carved by the Rapa Nui people between the 10th and 16th centuries to honor important ancestors and chiefs. The threat is not unprecedented; a magnitude 9.5 earthquake off the coast of Chile in 1960 triggered a tsunami that swept already-toppled moai further inland, damaging some features before the monument was restored in the 1990s. While the study focuses on Rapa Nui, its conclusions underscore a broader global reality: cultural heritage sites worldwide are increasingly imperiled by rising seas. A UNESCO report last month revealed that around 50 World Heritage sites are highly exposed to coastal flooding. Possible defences for Ahu Tongariki range from armoring the coastline and constructing breakwaters to the drastic measure of relocating the monuments. Mr Paoa hopes his findings will prompt these crucial conversations now, before irreversible damage occurs. "It's best to look ahead and be proactive instead of reactive to the potential threats," he urged. ___ The Associated Press receives support from the Walton Family Foundation for coverage of water and environmental policy.
