Random Access for LEO Satellite Communication Systems via Deep Learning
arXiv:2512.07053v3 Announce Type: replace-cross Abstract: Integrating contention-based random access procedures into low Earth orbit (LEO) satellite communication (SatCom) systems poses new challenges, including long propagation delays, large Doppler shifts, and a large number of simultaneous access attempts. These factors degrade the efficiency and responsiveness of conventional random access schemes, particularly in scenarios such as satellite-based internet of things and direct-to-device...
Mapping the Storm: Geospatial Impacts of Severe Weather on LEO Network Performance
Announce Type: cross Abstract: LEO satellite constellations, led by deployments such as Starlink, are playing an increasingly pivotal role in enabling global broadband connectivity. However, the reliability and performance of these space-based networks are highly sensitive to environmental dynamics, particularly localized weather phenomena that exhibit strong spatio-temporal variability. In this study, we present a continental-scale geospatial analysis of weather-induced performance...
Project SPARROW and the Future of Conservation Technology
arXiv:2606.00108v1 Announce Type: cross Abstract: Global biodiversity is declining at unprecedented rates, yet the tools available to monitor and protect ecosystems remain limited by constraints in power, connectivity, and accessibility. We present SPARROW, a hardware and software open-source platform that integrates solar energy, edge artificial intelligence, and satellite communication to enable continuous, autonomous biodiversity monitoring in remote environments. Each SPARROW node...
DRIFT: Joint Channel Estimation and Prediction Towards Pilotless 6G Non-Terrestrial Networks
Announce Type: cross Abstract: Non-terrestrial networks (NTNs) are expected to play a pivotal role in sixth-generation (6G) systems by enabling ubiquitous connectivity and massive communication. In this context, channel prediction emerges as a key technique to improve the spectrum utilization efficiency by limiting the pilot overhead. However, many proposed predictors based on artificial intelligence (AI) are characterized by high inference complexity, posing challenges to onboard...
'A pretty significant setback': How Blue Origin's rocket explosion affects NASA's moon plans
'A pretty significant setback': How Blue Origin's rocket explosion affects NASA's moon plans The shockwaves from Thursday's explosion will reverberate all the way to the moon. The recent explosion of Blue Origin's New Glenn rocket during a routine test is a big setback for the private spaceflight company, and will likely have implications for NASA's Artemis program timeline and the nation's efforts to return astronauts to the surface of the moon. The May 28 incident, in which no one was...
Blue Origin launchpad damaged in rocket explosion may not be restored until 2028, NASA's Isaacman says
NASA Administrator Jared Isaacman on Monday told CNBC that it will "take some serious time" to restore the launchpad damaged last week by a Blue Origin rocket explosion. Jeff Bezos' Blue Origin was conducting a hot-fire test of its massive New Glenn rocket on Thursday at a Space Force launch facility in Cape Canaveral, Florida, when the rocket erupted into a fireball. Bezos confirmed that all Blue Origin personnel were safe following the incident, and pledged to rebuild, while calling it a...
Rocket goes boom, satellite cameras zoom: Explosive Blue Origin damage is visible from space
Rocket goes boom, satellite cameras zoom: Explosive Blue Origin damage is visible from space New Glenn's launchpad is so cooked, satellites can see the char from orbit. The dust has settled in the aftermath of last week's giant New Glenn rocket explosion, which shook Florida's Space Coast and the space industry itself. Blue Origin was conducting a fueling test on May 28, ahead of New Glenn's fourth mission, when a yet unknown event led to the total destruction of the vehicle and significant...
US Space Force confirms SpaceX will build sensor-to-shooter targeting network
SpaceX has won a lucrative contract to provide the US military with a means of distributing space-based sensing and targeting data, forming the "backbone" of a rearchitected network after separate Pentagon initiatives stalled, officials announced Tuesday. Space Systems Command, the Space Force's primary procurement and acquisition center, announced the $2.29 billion firm-fixed-price agreement, confirming long-simmering reports that the Pentagon was likely to tap SpaceX for a new...
