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.

The global rise in wildfire frequency and intensity over the past decade underscores the need for improved fire monitoring techniques. To advance deep learning research on wildfire detection and its associated human health impacts, we introduce SmokeViz, a large-scale machine learning dataset of smoke plumes in satellite imagery. The dataset is derived from expert annotations created by smoke analysts at the National Oceanic and Atmospheric Administration, which provide coarse temporal and spatial approximations of smoke presence. To enhance annotation precision, we propose pseudo-label dimension reduction (PLDR), a generalizable method that applies pseudo-labeling to refine datasets with mismatching temporal and/or spatial resolutions. Unlike typical pseudo-labeling applications that aim to increase the number of labeled samples, PLDR maintains the original labels but increases the dataset quality by solving for intermediary pseudo-labels (IPLs) that align each annotation to the most representative input data. For SmokeViz, a parent model produces IPLs to identify the single satellite image within each annotations time window that best corresponds with the smoke plume. This refinement process produces a succinct and relevant deep learning dataset consisting of over 160,000 manual annotations. The SmokeViz dataset is expected to be a valuable resource to develop further wildfire-related machine learning models and is publicly available at https://noaa-gsl-experimental-pds.s3.amazonaws.com/index.

There are very few projects and companies currently aimed at tackling the issue. Breakthroughs, discoveries, and DIY tips sent six days a week. Nearly half of all known objects currently orbiting Earth technically classify as space junk, but the true amount may be even higher. Not only that, the debris continues amassing faster than it's being removed.

Probabilistic techniques are central to data analysis, but different approaches can be challenging to apply, combine, and compare. This paper introduces composable generative population models (CGPMs), a computational abstraction that extends directed graphical models and can be used to describe and compose a broad class of probabilistic data analysis techniques. Examples include discriminative machine learning, hierarchical Bayesian models, multivariate kernel methods, clustering algorithms, and arbitrary probabilistic programs. We demonstrate the integration of CGPMs into BayesDB, a probabilistic programming platform that can express data analysis tasks using a modeling definition language and structured query language. The practical value is illustrated in two ways. First, the paper describes an analysis on a database of Earth satellites, which identifies records that probably violate Kepler's Third Law by composing causal probabilistic programs with nonparametric Bayes in 50 lines of probabilistic code. Second, it reports the lines of code and accuracy of CGPMs compared with baseline solutions from standard machine learning libraries.

It filed a request with the FCC to deploy almost 52,000 satellites. Blue Origin has revealed its plans for an {@/data/467/1/1 orbital AI data center @/data/467/1/1} system in a new filing with the Federal Communications Commission. The company has asked the agency for permission to deploy 51,600 satellites, as reported by the and . Called Project Sunrise, the initiative aims to launch and operate a constellation of satellites that can deliver computing capacity for artificial intelligence uses. Project Sunrise's satellites will be placed in sun-synchronous orbits at altitudes between 311 and 1,118 miles.

The 590-kilogram (1,300 lbs) Van Allen Probe A crashed down in the East Pacific Ocean near the Galapagos Islands at 10:37 GMT (06:37 EDT) yesterday morning. NASA says it expected most of the spacecraft to burn up in the atmosphere, but some parts may have survived re-entry and reached the surface.

Why the world's militaries are scrambling to create their own Starlink The reliable internet connections provided by Starlink offer a huge advantage on the battlefield. Starlink's satellite constellation provides a reliable internet connection to almost anywhere on Earth, conferring an advantage on the modern battlefield. But it is also run by controversial billionaire Elon Musk, presenting a risk to militaries that could easily find themselves cut off. So, now countries are racing to build their own version. The Starlink network consists of almost 10,000 satellites that offer internet connections across most of the planet via small dishes on the ground.

California-based startup, Reflect Orbital, is poised to secure permission to launch a 60-foot (18.3-metre) prototype mirror into orbit to beam sunlight back to the Earth's surface. Once it has reached an altitude of 400 miles (640 km), the mirror will unfurl and illuminate a patch of Earth about three miles (4.8 km) wide. Someone looking up from the ground would see a small dot of light about as bright as the moon. Reflect Orbital says its space mirrors could allow solar power plants to operate 24 hours a day, provide lighting for disaster-struck regions, and even replace street lights.

The agency has been tracking the Van Allen Probe A and predicts it will reenter the atmosphere at around 7.45pm ET, though the exact timing could vary by up to 24 hours. Because the spacecraft is traveling thousands of miles per hour and the reentry window spans nearly a full day, scientists cannot predict exactly where debris may fall. NASA said most of the spacecraft is expected to burn up as it streaks through the atmosphere, although some components could survive the fall. The risk of anyone being harmed is extremely low, estimated at roughly 1 in 4,200.
