GE Aerospace a demonstrat ceea ce susține că este primul test de platformă hipersonic cu reacție dublu-mode Ramjet (DMRJ) din lume care utilizează arderea cu detonare rotativă (RDC) într-un flux supersonic care ar putea oferi într-o bună zi rachetelor hipersonice o rază de acțiune mai mare.

O substanță chimică sugerează că viața extraterestră este obișnuită

Marţi, 05 Decembrie 2023 14:39
Phosphorus – a key ingredient for life as we know it – was thought to be relatively rare in space. But now, astronomers have detected a surprising amount of the stuff on the fringes of the galaxy, suggesting life may be more common in the cosmos. Life on Earth requires six critical elements: nitrogen, carbon, hydrogen, oxygen, phosphorus and sulfur (NCHOPS). Most of those are relatively easy to come by, as they’re blown into space as common low-mass stars reach the end of their lives. Phosphorus, meanwhile, is much rarer, and as such is generally considered the limiting factor for life in the universe.

NASA modifică software-ul Voyager pentru a proteja propulsoarele împotriva gunge-ului

NASA Voyager mission engineers are preparing a software patch that will allow the thrusters aboard the Voyager 1 and 2 interstellar probes to continue operating for another five years, keeping the spacecraft in communications with Earth. The Voyager spacecraft have been in service since their launch in 1977 and have exceeded their life expectancy many times over. They're a testament to the teams that designed them, but after almost half a century their very longevity is creating new problems that were never anticipated.

Northrop Grumman va construi un obuz pentru Marina SUA

Joi, 12 Octombrie 2023 17:49

The new shell will be able to automatically track and steer toward moving targets

As the age of the smart weapon continues, Northrop Grumman has been awarded a US Navy contract to develop a new self-guided 57-mm artillery shell for the Navy's Mk110 Naval Gun Mount medium-sized gun used on Littoral Combat Ships.

If you watch old movies or newsreels of naval combat, they tend to resemble gunpowder-besmirched storms with shot and shell blasting all over the place like steel rain. Today, things have changed as the major navies rely much more on precision rather than sheer firepower. Instead of massive salvos of giant shells packed with high explosives fired in the hopes of one of them landing close enough to the target to cause some damage, the goal nowadays is to shoot one round filled with not much explosives designed to land just where it can do the most good – or the most harm, depending on your point of view.
