ESA’s Plan to Remove Space Debris Needs Global Collaboration

Credit: DepositphotosThe issue of space debris has been growing for years, exacerbated by the continuous launch of rockets and payloads. In recent years, organizations, particularly the European Space Agency (ESA), have begun to take the issue more seriously. Now, they are asking: How can we achieve zero space debris?The Scale and Danger of Space...

A New Fuel is Capable of Enduring the Extreme Conditions Within a Nuclear Thermal Propulsion Reactor

The new fuel could pave the way for future nuclear rocket enginesGeneral AtomicsGeneral Atomics Electromagnetic Systems (GA-EMS) has successfully tested nuclear fuel designed for future spacecraft propulsion and power. The tests confirm the fuel's ability to endure the extreme conditions of a nuclear rocket reactor.Until now, spacecraft have primarily relied on chemical rockets for...

Ocean Current Defies Doomsday Predictions, Stays Steady for 60 Years

Previous AMOC studies relied on sea surface temperature data. A CTD rosette device measures the ocean’s conductivity, temperature, and depth by collecting water samples at varying depths, makingmodels more accurate than ever.
