The commander of Nasa's next mission to the Moon said that he and his crew would see things that no human has ever seen. Reid Wiseman told a news conference that it was likely that his spacecraft would fly over large areas of the Moon that previous Apollo missions had never mapped. Yesterday, Nasa announced it hoped it would be able to launch the first crewed Moon mission in 50 years as early as February 2026 . Mission specialist Christina Koch explained that the astronauts would be able to study the lunar surface in exquisite detail for a full three hours. Believe it or not, human eyes are one of the best scientific instruments that we have, she said.

Is recognising Palestine a way to'save face' for Western leaders? Organisers of the Global Sumud Flotilla, a Gaza-bound flotilla with pro-Palestinian activists on board carrying aid, reported hearing explosions and seeing multiple drone attacks from their boats situated off Greece from late Tuesday to the early hours of Wednesday. "Multiple drones, unidentified objects dropped, communications jammed and explosions heard from a number of boats," the Global Sumud Flotilla said in a statement, without adding whether there were any casualties. "We are witnessing these psychological operations firsthand, right now, but we will not be intimidated." Suited in a life jacket, Brazilian organiser Tiago Avila updated on his Instagram at midnight on Wednesday that a total of 10 attacks targeted multiple boats with sound bombs and explosive flares.

Accurate recognition of vessel types from Automatic Identification System (AIS) tracks is essential for safety oversight and combating illegal, unreported, and unregulated (IUU) activity. This paper presents a strait-scale, machine-learning pipeline that classifies moving vessels using only AIS data. We analyze eight days of historical AIS from the Danish Maritime Authority covering the Bornholm Strait in the Baltic Sea (January 22-30, 2025). After forward/backward filling voyage records, removing kinematic and geospatial outliers, and segmenting per-MMSI tracks while excluding stationary periods ($\ge 1$ h), we derive 31 trajectory-level features spanning kinematics (e.g., SOG statistics), temporal, geospatial (Haversine distances, spans), and ship-shape attributes computed from AIS A/B/C/D reference points (length, width, aspect ratio, bridge-position ratio). To avoid leakage, we perform grouped train/test splits by MMSI and use stratified 5-fold cross-validation. Across five classes (cargo, tanker, passenger, high-speed craft, fishing; N=1{,}910 trajectories; test=382), tree-based models dominate: a Random Forest with SMOTE attains 92.15% accuracy (macro-precision 94.11%, macro-recall 92.51%, macro-F1 93.27%) on the held-out test set, while a tuned RF reaches one-vs-rest ROC-AUC up to 0.9897. Feature-importance analysis highlights the bridge-position ratio and maximum SOG as the most discriminative signals; principal errors occur between cargo and tanker, reflecting similar transit behavior. We demonstrate operational value by backfilling missing ship types on unseen data and discuss improvements such as DBSCAN based trip segmentation and gradient-boosted ensembles to handle frequent-stop ferries and further lift performance. The results show that lightweight features over AIS trajectories enable real-time vessel type classification in straits.

President Trump's state visit to the UK secured $350 billion in US tech investments to strengthen Britain's AI capabilities and counter Chinese influence.

The National Hurricane Center (NHC) revealed their updated tracks for a pair of tropical disturbances brewing in the Atlantic, giving both a high likelihood of turning into named storms within seven days . One of these threatening weather systems, currently dubbed Invest 94L, is expected to form right off the coast of Florida . The other potential storm, called Invest 93L, has been developing in the middle of the Atlantic and forecasters unveiled an initial path that could take it towards the Carolinas by the end of the week.

How is Russia replenishing its military? What is a'coalition of the willing'? How China forgot promises and'debts' to Ukraine How are Europe, the US pulling apart on Ukraine? Copenhagen airport shut after sighting of'unidentified drones' Authorities in Denmark have closed Copenhagen airport after unidentified drones were sighted nearby, causing about 15 flights to be diverted, police and airport officials told the AFP news agency. "The airspace over Copenhagen airport has been closed since 8:30pm (18:30 GMT) due to two to three unidentified drones. No aircraft can take off or land," airport spokeswoman Lise Agerley Kurstein said.

How is Russia replenishing its military? What is a'coalition of the willing'? How China forgot promises and'debts' to Ukraine How are Europe, the US pulling apart on Ukraine? A Ukrainian drone attack killed three people and injured 16 near the town of Foros on the Crimean Peninsula, the Russian-appointed head of Crimea, Sergei Aksyonov, wrote in a post on Telegram. Russia's Ministry of Defence said the attack occurred "using strike drones equipped with high-explosive payloads", in a resort area "where there are no military targets whatsoever".

How is Russia replenishing its military? What is a'coalition of the willing'? How China forgot promises and'debts' to Ukraine How are Europe, the US pulling apart on Ukraine? Russian forces launched a large-scale missile and drone attack, targeting areas across Ukraine, killing at least three people and wounding dozens more, according to Ukrainian officials. Ukrainian President Volodymyr Zelenskyy said Russia launched 580 drones and 40 missiles, and that the attacks took place across nine regions, including Dnipropetrovsk, Mykolaiv, Chernihiv, Zaporizhia, Poltava, Kyiv, Odesa, Sumy and Kharkiv.

During WWII, the U.S. government censored the weather Even baseball rain delays went unexplained. A World War II poster, created for the War Production Board around 1942-1943, declares "Weather is a weapon." Breakthroughs, discoveries, and DIY tips sent every weekday. The call went out from WREC's studios in downtown Memphis at 6:57 p.m. Central War Time: Doctors and nurses were urgently needed in communities south and west of the city. That was all the information the station was allowed to provide, despite the ongoing threat.
