The forces of rotation caused red hot masses of stones to be torn away from the Earth and to be thrown into the ether, and this is the origin of the stars.

Stealth radio hides signal in background noise to protect drone pilots

New Scientist Space - Cosmology - Mon, 09/15/2025 - 8:00am
As drones have risen to prominence on the battlefield, so too has electronic warfare, in which adversaries attempt to mask, jam or trace radio signals. Now, a new stealthy radio device could help give people the edge, letting them fly drones without detection

RISE: ESA’s mission extender in geostationary orbit

ESO Top News - Mon, 09/15/2025 - 8:00am
Video: 00:01:43

An essential part of ESA’s Space Safety programme is dedicated to getting and keeping Earth’s orbits clean from space debris. In the long run, the Agency aspires to stimulate a true circular economy in space, minimising the impact of spaceflight on Earth and its resources where possible. As part of ESA’s Zero Debris approach, new ESA missions will be designed for safe operations and disposal to stop the creation of new debris by 2030.  

ESA has now taken another important step on the road towards sustainability in space with its first in-orbit servicing mission RISE, planned for launch in 2029. 

RISE is a commercial in-orbit servicing mission that will demonstrate that it can safely rendezvous and dock to a geostationary client satellite, extending the life of geostationary satellites that need support with attitude and orbit control, but are otherwise in working order.  

After verifying that it meets all the performance standards in a first demonstration, prime contractor, operator and co-founder D-Orbit will start commercial life extension services for geostationary satellites. 

ESA’s RISE mission marks a promising step towards enhancing in-orbit services and technologies, such as refuelling, refurbishment and assembling – all essential elements for creating a circular economy in space.

The death of dinosaurs dramatically re-engineered Earth's landscapes
