JAXA H3 Rocket Achieves Success with First Low-Cost Variant Launch

JAXA's H3 rocket successfully launched its "30 configuration," the lowest-cost variant using only liquid fuel engines. This completes the H3 family with three configurations of varying capabilities and costs, fulfilling a decade-long development goal. The 30 configuration offers cost savings by omitting solid rocket boosters, making it suitable for smaller satellites and enhancing JAXA's market competitiveness.

Inspired by crocodile scales, Chinese armour tech said to deflect projectiles

Chinese researchers say they have developed a crocodile-inspired ceramic body armour that can deflect projectiles and potentially offer a low-cost alternative for lightweight ballistic protection. The team – led by associate research fellow Zhaoxiu Jiang at Ningbo University – based their design on the asymmetric, overlapping scales of crocodile skin, which provide a protective barrier against predators and other crocs. Their research findings were published on March 25 in the peer-reviewed...

Defence sovereignty: Europe races to build the low-cost weapons of future

With Trump wavering on Nato and war in Ukraine, Europe is scrambling to spend billions on weapons such as dronesIn a small workshop in England’s East Midlands, engineers at the British startup Skycutter are designing weapons for Ukraine. A row of 3D printers make the fuselage for interceptor drones, while parts such as motors and navigation chips are slotted together by hand. The same process happens hundreds of thousands of times a month in partner Ukrainian factories.The swarms of cheap, deadly and often autonomous drones deployed in that war have already changed combat completely. Troops far behind the frontline must move constantly to avoid attack from the air, travelling along netted tunnels and landscapes crisscrossed by fibre optic cables used to steer drones past radio jamming. Cities are terrorised by guided missiles that are cheaper and therefore more widely used than those that came before. Continue reading...

AirAsia to launch new airline, flying against wind of high oil costs

AirAsia X co-founder Tony Fernandes said he is preparing to launch a new airline, betting that expanding while the aviation industry’s being roiled by high oil prices will pay off in the future. The new airline will be announced in the next month or two, Fernandes said in a video interview from Montreal late on Wednesday. The low-cost Southeast Asian carrier group is moving some planes for the business it is starting, he said, without providing further details. The expansion would come on the...
