Moving satellites to meet a plane for rare reentry data
When satellites eventually fall back down to Earth, they mostly burn up because of the friction caused by the atmosphere. Scientific data about this atmospheric reentry process is urgently needed to design future satellites for a quick, safe and sustainable demise at the end of their mission – reducing risks on the ground and in space.
The European Space Agency (ESA) successfully manoeuvred its remaining two Cluster satellites to ensure they can both be observed from a plane as they reenter the atmosphere on 31 August and 1 September 2026.

Space activities are unlike any others. They interact not just with Earth, but with three interconnected environments: Earth, Earth’s orbit, and the Moon and deep space. On Earth, we aim to reduce the space sector’s environmental impacts while maximising the societal and environmental benefits of our missions. In orbit, we manage space debris and collision risks to maintain safe and secure operations. For the Moon and deep space, we are laying the foundations to minimise the impact of our missions on and around other celestial bodies.
Guided by our core values, ESA is committed to making its activities

MDA Space and Hanwha target Korean K-LEO defense network
MDA Space has signed a Memorandum of Understanding with Hanwha Systems to pursue collaboration on Korea's planned sovereign Low Earth Orbit K-LEO defense constellation, targeting enhanced military communications and data services for national security operations. The agreement sets a framework for the two companies to explore how MDA Space's AURORA software-defined digital satellite platform can Airspan 5G platform selected for Space Compass high altitude maritime network
Airspan Networks Holdings LLC has announced that it will deploy a 5G Air-to-Ground communications system for Space Compass's High-Altitude Platform Station, creating a new capability for maritime domain awareness from the stratosphere. The partnership will use high-altitude aircraft operating around 16 to 18 kilometers to extend secure broadband connectivity far beyond the reach of conventional Gravitational wave triad puts relativity under intense scrutiny
An international team working within the LIGO Virgo KAGRA collaboration has used the exceptionally clear gravitational wave signal GW250114 to carry out some of the most precise tests yet of Einstein general theory of relativity. The work, which appears in Physical Review Letters, relies heavily on contributions from researchers at the Max Planck Institute for Gravitational Physics (Albert Einst AI framework links gravitational waves and radio afterglows
When two neutron stars collide, they generate gravitational waves and light across the electromagnetic spectrum, from intense gamma ray flashes to faint radio signals that can persist for years. These multi-messenger events contain rich information about the physics of compact objects, their environments and the formation of heavy elements, but extracting that information efficiently has proved Smartphone kit offers low cost on site radiation dose checks
Prompt, individual dose assessment is a critical part of protecting people after large scale nuclear or radiological incidents, but traditional dosimetry relies on expensive instruments or laboratory processing that can delay decisions on medical care. Researchers at Hiroshima University have now demonstrated a portable, low cost system that pairs a small piece of radiochromic film with a foldab
