- 1New Satellite Engine Could Use Earth's Atmosphere as Fuel●New Satellite Engine Could Use Earth's Atmosphere to Stay in Orbit Indefinitely
Researchers have developed an air-breathing electric propulsion engine that could allow satellites in very low Earth orbit to refuel on atmospheric molecules instead of stored propellant. By compressing and ionizing thin air at high altitudes, the engine could keep spacecraft flying indefinitely, extending mission lifetimes and opening new possibilities for Earth observation and communications. The concept is drawing wide interest among space enthusiasts and engineers debating its practical limits and potential applications.

Starlab, the planned commercial space station being developed by Voyager Space and Airbus, is being discussed as a possible answer to Europe's orbital ambitions once the International Space Station is retired around 2030. The question being raised is whether the station can give European astronauts and researchers continued access to low Earth orbit, and whether Europe should commit to the project or pursue other options.

The Pentagon is advancing plans for satellite constellations designed to track targets, including hypersonic missiles, from orbit. Aviation Week reports the programs are moving from concept toward deployment, with layered networks of small satellites in low Earth orbit intended to provide persistent tracking and targeting data for missile defense.
- 7ICEYE and Nokia partner on sovereign LEO satellite communications●Finnish ICEYE and Nokia are partnering to develop secure, sovereign low Earth orbit (LEO) satellite communication system
Finnish companies ICEYE and Nokia are teaming up to develop a secure, sovereign low Earth orbit satellite communication system aimed at government users, including defense and emergency services. The system would rely on European technology, with first launches expected in 2028. The partnership reflects growing European interest in independent space-based communications infrastructure amid security concerns.
- 8SpaceX advances open orbit while debris risks mount▼SpaceX's advances are making orbit far more accessible even as debris risks accelerate. https://www. japantimes.co.jp/co
SpaceX's rapid progress with reusable rockets and Starship is making access to orbit cheaper and more frequent, but experts warn the growing number of launches and satellites is accelerating space junk risks. Commentary in The Japan Times argues that easier access to space is colliding with mounting debris concerns, prompting calls for better traffic management and cleanup efforts as more actors crowd low Earth orbit.

NASA and SpaceX launched the Crew-13 mission to the International Space Station, continuing their routine astronaut ferry flights aboard SpaceX's Crew Dragon spacecraft. The mission carries a new crew to the orbiting laboratory, maintaining the rotation of personnel and ongoing research operations in low Earth orbit. Coverage highlights the ongoing partnership between the space agency and the private launch provider.
- 11NASA's growing dependence on SpaceX sparks criticism●# NASA is now at the mercy of # SpaceX , but… «SpaceX and its founder, Elon Musk, will do what they want.» A requiem for
Commentary is circulating arguing that NASA has lost leverage over SpaceX and Elon Musk after two decades of subsidizing private space companies and relying on them for low Earth orbit flights. The piece calls it a 'requiem' for the space economy, claiming the agency is now at the mercy of a contractor that 'will do what they want.' It reflects wider concern about NASA's dependence on a single commercial partner.

Commentators are pointing to a recent event in low Earth orbit as a possible turning point in the onset of Kessler Syndrome, the cascade where collisions between orbiting debris create ever more debris. One widely shared remark says future observers may look back and say 'this is when it started', reflecting growing anxiety about overcrowding and collision risk in orbit.
- 14ESA warns of runaway object growth in low Earth orbit▼ESA’s space environment report warns of “skyrocketing, runaway” objects in low Earth orbit
The European Space Agency has released its annual space environment report, warning that the number of objects in low Earth orbit is increasing at a 'skyrocketing, runaway' pace. The agency cautions that debris from satellite launches, collisions and break-ups is accumulating faster than it can be removed, raising the risk of cascading collisions that could threaten spacecraft and future missions.
