India achieves milestone with launch of first private-sector orbital rocket

Al Jazeera

India has successfully tested its first private-sector orbital rocket, marking a milestone in New Delhi's ambition to become a major player in the global space economy. The three-stage 22-metre Vikram-1 was launched from the Satish Dhawan Space Centre in Sriharikota and deployed customer payloads into a 450km (280-mile) low-Earth orbit, making India the third country to achieve orbital launch capability through private enterprise. It also carried experimental equipment, a lab-grown diamond and a miniature 18-carat gold sculpture commemorating India's national space programme. India Prime Minister Narendra Modi hailed the achievement, saying that it will "encourage countless youngsters to dream bigger and innovate fearlessly". Founded in 2018, Skyroot is among a new generation of Indian space startups that have attracted backing from global investors following the sector's liberalisation.

Report suggests SpaceX is testing a handheld AI device, Musk says it's 'utterly false'

Engadget

Report suggests SpaceX is testing a handheld AI device, Musk says it's'utterly false' Report suggests SpaceX is testing a handheld AI device, Musk says it's'utterly false' The purported gadget was reported to offer a way to access xAI's models without having to use a smartphone. SpaceX, the newly-public satellite internet company that also dabbles in rockets and CSAM-generating chatbots, might be building its own AI hardware. In the minutes since our article published, Elon Musk has replied to a post on X to say that the report is utterly false. The rest of this story below covers what the original article reported. The device is slimmer than an iPhone, according to, and is powered by one of Qualcomm's Snapdragon chips.


An Explosion Knocked Out Anduril's Rocket Motor Test Site in Mississippi

WIRED

The incident could disrupt a key part of the defense company's rocket motor business, which designs and tests prototype motors for military customers. A rocket motor exploded during a test at an Anduril facility in Mississippi last Friday, marking another setback in the startup's hopes of becoming a major supplier of missile propulsion systems for the defense industry. Anduril publicly confirmed the incident after an inquiry from WIRED. No one was injured in the blast, which damaged Anduril's testing stand, the company's chief operating officer Matt Grimm said in a social media post on Tuesday hours after WIRED contacted the company about the incident. Three people familiar with Anduril's operations, who were granted anonymity to discuss a sensitive situation, tell WIRED that they can't recall another time when a similar test resulted in an explosion in the past few years, and they were unaware of what may have caused last week's mishap.

U.S. defense firm Anduril in talks for Nissan plant to build drones in Japan, sources say

The Japan Times

U.S. defense firm Anduril in talks for Nissan plant to build drones in Japan, sources say U.S. defense firm Anduril Industries is in talks to acquire the plant to build military drones in Japan, sources say. U.S. defense firm Anduril Industries is in talks to acquire Nissan Motor's Oppama assembly plant near Tokyo as the maker of autonomous weapons looks to build military drones in Japan, according to three sources familiar with the matter. While they say no decision has been made, any deal could transform one of Japan's first large-scale postwar car factories, long a symbol of its industrial revival, into an arms-making hub. The talks over Oppama, which are being reported for the first time, come as Prime Minister Sanae Takaichi's government seeks to expand defense manufacturing amid growing concern that a Taiwan Strait crisis could draw in Japan and run down weapons stocks.

China's mineral squeeze testing Japan's military buildup

The Japan Times

Samples of rare earth luminescent materials displayed at an exhibition on China's manufacturing achievements at the National Museum in Beijing in March | REUTERS China's tightening export controls on dual-use materials and strategically important rare earths are beginning to disrupt Japanese industry -- including the defense sector. Chinese customs data tell the sharpest part of the story. Exports of dysprosium oxide to Japan ceased after October 2025, and shipments of terbium oxide ended a month later. No shipments of either material have been recorded since. The halt matters because dysprosium and terbium -- both heavy rare earth elements -- are among the most critical inputs for high-performance permanent magnets used in advanced military systems, electric vehicle motors, aerospace applications and industrial robotics.


Flow World Benchmark for Flying on a Word Learning

Neural Information Processing Systems

Unmanned Aerial Vehicles (UAVs) are evolving into language-interactive platforms, enabling more intuitive forms of human-drone interaction. While prior works have primarily focused on high-level planning and long-horizon navigation, we shift attention to language-guided fine-grained trajectory control, where UAVs execute short-range, reactive flight behaviors in response to language instructions. We formalize this problem as the Flying-on-a-Word (Flow) task and introduce UAV imitation learning as an effective approach. In this framework, UAVs learn fine-grained control policies by mimicking eUAxpert pilotVtrajectoriesFlopaired withwatomic Fly around the tree ahead Land on the left side of carlanguage instructions. To support this paradigm, we present UAV-Flow, the firstreal-world benchmark for language-conditioned, fine-grained UAV control.


OrbitZoo: Real Orbital Systems Challenges for Reinforcement Learning

Neural Information Processing Systems

The increasing number of satellites and orbital debris has made space congestion a critical issue, threatening satellite safety and sustainability. Challenges such as collision avoidance, station-keeping, and orbital maneuvering require advanced techniques to handle dynamic uncertainties and multi-agent interactions. Reinforcement learning (RL) has shown promise in this domain, enabling adaptive, autonomous policies for space operations; however, many existing RL frameworks rely on custom-built environments developed from scratch, which often use simplified models and require significant time to implement and validate the orbital dynamics, limiting their ability to fully capture real-world complexities. To address this, we introduce OrbitZoo, a versatile multi-agent RL environment built on a highfidelity industry standard library, that enables realistic data generation, supports scenarios like collision avoidance and cooperative maneuvers, and ensures robust and accurate orbital dynamics. The environment is validated against various real satellite constellations, including Starlink, achieving a Mean Absolute Percentage Error (MAPE) of 0.16% compared to real-world data. This validation ensures reliability for generating high-fidelity simulations and enabling autonomous and independent satellite operations. This project is open source1 and has a dedicated project page2.


SpaceX overtakes Amazon as world's fifth most valuable company

SpaceX overtakes Amazon to become world's fifth most valuable company Elon Musk's firm briefly reached $2.97tn valuation days after its IPO following purchase of AI coding startup Cursor SpaceX has overtaken Amazon to become the world's fifth most valuable company days after its stock market debut . The milestone came as Elon Musk's company agreed to buy the startup behind the AI-powered coding app Cursor for $60bn (£44bn), in an attempt to capitalise on the technology's success as a coding tool. SpaceX is the parent of Musk's AI business, xAI, which will be able to boost its capabilities in an area - AI systems writing code - that has proven to be a strong commercial success for Anthropic, the rival company behind the Claude chatbot.
