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.

The lab will beam back data to train AI models to predict how proteins behind age-related diseases like Alzheimer's and certain cancers behave. Space is becoming the next frontier in longevity research. A British startup just launched self-run chemical experiments into orbit, in the hopes zero-gravity data might shine a light on a group of disease-causing proteins too difficult to study on Earth. But first they need to check their autonomous laboratory will work in space. Mass Balance's grapefruit-sized apparatus containing chemicals, sensors and control elements to keep the chemicals functioning launched on a SpaceX transporter on Tuesday morning.

A robotic spacecraft called LINK will soon tug the telescope to a higher orbit. The NASA Swift Boost mission has launched from Marshall Islands on July 3 at 4:36AM Eastern time after a couple of delays, and the agency has started preparing it for its ultimate goal: To rescue the Neil Gehrels Swift Observatory, which is falling faster than anticipated. Swift Boost's ground teams have already established communication with LINK, the robotic spacecraft designed by Arizona company Katalyst Space to dock with the observatory and to tug it back into a higher orbit. LINK was attached to a Northrop Grumman Pegasus XL rocket, which was in turn attached to the belly of a plane called Stargazer. The plane took off from Kwajalein Atoll, Marshall Islands and then released the Pegasus XL rocket in the air at an altitude of around 40,000.

Image caption, Artist's impression of the Swift observatory which was built to study the cosmos A Nasa-funded spacecraft has been sent into space to catch a falling telescope. The Swift observatory detects some of the most powerful explosions in the Universe - but is at risk of crashing back to Earth in the coming months. The small space telescope will be intercepted by the LINK craft, which will attempt to grab it with three robotic arms, and try and lift it back to a safe orbit. The rescue mission, launched on Friday, has never been attempted before, and Dr Simeon Barber, a space scientist, has said it is high risk. But Nasa obviously thinks it's worth a go.

A deep network's loss is invariant to continuous symmetries of its parameters: the logit shift, the ReLU rescaling, the LayerNorm scale, the per-head attention rotation. Adam's per-coordinate preconditioner drifts along each symmetry orbit, which pulls the trajectory off the symmetry quotient where the optimization lives and blurs the singular-learning rate the quotient makes readable. We build DDC, a Dead-Direction Conditioner that lifts a base optimizer into a $G$-equivariant one: it conditions the optimizer's state in the orbit decomposition of a $G$-invariant metric, so the trajectory stays a preconditioned gradient flow on the quotient $\barΘ= Θ/G$. The construction carries four architectural gauges (cross-entropy shift, ReLU and SwiGLU rescaling, LayerNorm and RMSNorm scale, and a per-head $O(d_{\rm head})$ attention rotation matched to RoPE), proves exactly equivariant on an Adam base, and composes with a Muon base through a gauge-equivariant orthogonaliser. Respecting the symmetry changes both the minimum the optimizer reaches and what it leaves measurable there. On a language model trained past the point of fit, DDCAdam resists the over-training collapse AdamW falls into, holding a validation-train loss gap of 0.67 against 5.88, and reads the dead-direction rate in 32 of 65 layer-by-observable cells where AdamW reads it in 7. A vision transformer trained from scratch reaches lower validation loss (1.71 against 2.12) while compressing spare feed-forward capacity a matched AdamW leaves intact. On a Muon base, where the rotation gauge composes exactly, DDCMuon groks ten of eleven seeds at depth 24 that a plain Muon never reaches. Built into the optimizer, a network's gauge symmetry sharpens the minimum it finds and turns that minimum's geometry into something the trajectory can measure.

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.
