一 | In the world of Telugu cinema, filmmakers have often staked their careers to capture their dreams on celluloid. Director Sujeeth, whose recent film They Call Him OG grossed about Rs 300 crore at the box office, is in the news for a personal sacrifice he made during its filming. Pawan Kalyan’s gesture The sacrifice came to light recently when OG's hero, actor-politician Pawan Kalyan, gifted him a luxury car (Land Rover Defender) worth Rs 3 crore. Power Star's gesture has a backstory. During the filming of OG, Sujeeth had to surrender his own wheels to the wind. He had to trade his personal luxury - a Land Rover Defender - to fund a crucial schedule in Japan. Since the producer of OG was unwilling to fund the schedule and Sujeeth didn't want to compromise on authenticity, he sold off his luxury vehicle, something about which Pawan Kalyan learned only much later. Sujeeth overwhelmed Best gift ever. Overwhelmed and grateful beyond words. The love and encouragement from my dearest OG, Kalyan garu, means everything to me. From being a childhood fan to this special moment. Forever indebted," wrote Sujeeth, after receiving it from the Deputy CM of Andhra Pradesh. After the release of OG in September this year, Sujeeth posted on social media: "From being a childhood fan to this special moment... the love and encouragement from my dearest OG, Kalyan garu, means everything to me." While star heroes like SRK have previously gifted luxury cars to filmmakers/artists, they were more tokens of appreciation. Among recent instances where something similar happened, Kamal Haasan gifted director Lokesh Kanagaraj a Lexus ES 300h (worth roughly Rs 65 lakh) after the success of Vikram in 2022. Kamal was so moved by Lokesh’s fan-boy dedication and the film's technical brilliance that he also gifted motorbikes to all 13 assistant directors.

Representing a significant scientific iteration from the 2024 version, this map effectively rewrites the moon's geologic history based on the latest research findings. "The lunar geologic history has indeed been rewritten -- more precisely, refined and systematized," said Yang Zhiming, director of the IGCAGS. Specifically, a primary achievement of this update is the recalibration of the moon's ancient geologic eras. The new map systematically updates the age boundaries of the moon's three ancient geologic periods, namely the Aitkenian, Nectarian and Imbrian periods, drawing on recent advances in international chronology. Crucially, Chang'e-5 samples confirmed volcanic activity on the moon as recently as 2 billion years ago, extending its geologic lifespan by 1 billion years from the previously accepted 3 billion years. This independent dating data has now become a cornerstone of the global lunar geologic timescale. Highlighting these spatial discoveries, the new global lunar geologic map is the first comprehensive canvas to bear exclusive findings from the Chang'e-6 mission. "The lunar samples and this map will provide a new starting point for scientific discussions regarding the lunar far side," said Jin Ming, an associate researcher at the IGCAGS. The map details the age of young mare basalts on the lunar far side obtained from the Chang'e-6 samples, recording the region's volcanic history. Furthermore, it reveals that KREEP rocks, enriched with rare earth elements and other strategic resources, are far more continuous and abundant in the Oceanus Procellarum than previously estimated. This discovery, achieved by eliminating spectral noise, prompts a systemic reevaluation of the moon's early magma ocean crystallization and internal thermal evolution. Beyond its scientific data, the 2.8-by-1.2-meter map introduces a proprietary cartographic standard. Identifying over 13,500 impact craters and 81 basins, it employs a unique color scheme rooted in geologic logic and traditional Chinese aesthetics, following a "lighter for younger, darker for older" principle. Furthermore, this standard will also be applied to future geologic mapping of Mars and asteroids, ending reliance on foreign standard systems. "This goes beyond showcasing technological soft power. This standard will be extended to future planetary geologic mapping, establishing an independent intellectual property framework for China's deep space exploration," Yang said. 。
