A Chinese Zhuque-2E rocket upper stage deorbited over Minnesota, leaving an unusually large piece of debris in a farmer's cornfield after a likely botched deorbit burn following its September 15 launch carrying 10 Qianfan communications satellites.
A Curtin University study reveals that Starlink satellites emit unintended radio signals up to 10,000 times stronger than cosmic signals required for SKA-Low radio astronomy, potentially making key frequency bands unusable.
Russia's Rassvet satellite constellation, intended to rival SpaceX's Starlink, is facing slow progress and technical failures, with satellites not reaching intended operational altitudes. The article discusses uncertainties and challenges in Russia's satellite manufacturing capabilities.
SpaceX's Falcon 9 sets a new record with its 37th flight, marking the end of Starlink missions from Florida as future launches shift to customer payloads and preparations for Starship.
Elon Musk tweeted about Starlink's growth, from two prototype satellites in 2018 to over 11,000 in orbit by 2026, forming the largest satellite constellation in human history.
China launched the first satellite of its Gande Constellation, a 120-satellite commercial network for round-the-clock space debris monitoring, aiming for full deployment by 2030.
Xona Space Systems is developing a constellation of 258 low-Earth orbit satellites called Pulsar to provide a GPS alternative with 100x stronger signals, enabling centimeter-level accuracy indoors and in dense urban areas, with initial launches planned for October 2026.
This article explores whether the Starlink satellite constellation could be used as a secret radar system by analyzing the principles of synthetic aperture radar and comparing existing SAR satellites. It points out that while it has theoretical radar detection potential, there is no evidence it is currently operational.
A Chinese rocket's upper stage broke apart in low Earth orbit, creating debris that poses a risk to the International Space Station and SpaceX's Starlink satellites.
The FCC waived the requirement for Amazon to launch half of its satellite broadband constellation by July 2026, giving the company more time while keeping the final 2029 deadline for full deployment.
Google's moonshot project, Project Suncatcher, aims to deploy AI compute in space-based data centers powered by solar energy. The biggest technical bottleneck is dissipating heat from densely packed TPUs in a vacuum environment—where cooling can only rely on radiation. Radiators can only shed a few hundred watts per square meter, a gap of several orders of magnitude from the thousands of watts per chip handprint, meaning each TPU would require several square meters of radiating surface.
