Scientists have toyed with the idea of nuclear rockets since the 1950s. Will they finally become a reality? UK startup Pulsar ...

UK startup Pulsar Fusion today unveiled “Sunbird,” a nuclear fusion-powered rocket concept that could halve the time it takes to travel across our solar system — and, maybe, beyond it.

"From developing small robots that could swim through the oceans of other worlds to growing space habitats from fungi, this program continues to change the possible." ...

is about ten billion times more than the hydrogen-oxygen combustion that powers space shuttles’ main engines and 300 times more than the fusion reactions at the Sun’s core,” remarked the ...

At the forefront of this revolution is Pulsar Fusion, a UK-based company pushing the boundaries of science and engineering to create a new generation of rocket engines. The heart of this ...

The plasma (blue) is injected into the rocket nozzle. Lithium metal rings (red) then collapse at great force around the plasma, compressing it to fusion conditions. The sudden release of fusion ...

Because c is very large, a small amount of missing mass turns into a large amount of energy. The main fuels used in nuclear fusion devises are deuterium and tritium, both heavy isotopes of hydrogen.

There are no CO 2 or other harmful atmospheric emissions from the fusion process, which means that fusion does not contribute to greenhouse gas emissions or global warming. Its two sources of fuel, ...

MOSCOW, August 25. /TASS/. The work to develop the hydrogen-powered stage for the Angara-A5V carrier rocket with the increased lift capacity will begin after 2025, acting CEO of the Khrunichev ...

There are a number of different nuclear fusion reactions happening in the Sun. The simplest is when four hydrogen nuclei become one helium nuclei.

Teams encountered a liquid hydrogen leak while loading the propellant into the core stage of the Space Launch System rocket. Multiple troubleshooting efforts to address the area of the leak by ...

While many scientists are looking into theoretical space engines, others are focusing on the tried and true—such as plain old-fashioned engines that burn rocket fuel. In this new study ...
