Methane is better suited for reusable engines because they leave less behind sooty residue than kerosene, which SpaceX uses on the Falcon 9 rocket.

CMCs are a composite material, one in which the fibers are ceramic or carbon, embedded in a ceramic matrix. They are created to overcome the brittleness of traditional ceramics, while providing high-temperature resistance, light weight, and high strength. According to DSTL, they are capable of withstanding temperatures exceeding 1,000°C (1,832°F), and unlike metals, they hold their strength and shape under extreme heat and stress.

Today is Wednesday, Jan. 21, the 21st day of 2026. There are 344 days left in the year. Today in history: On Jan. 21, 1976, British Airways and Air France inaugurated scheduled passenger service on the supersonic Concorde jet.

This will be Rocket Lab's fourth hypersonic test mission for the military in under six months, deploying the DART AE hypersonic demonstrator drone from Australia's Hypersonix Launch Systems. The quick cadence of these flights shows how Rocket Lab is helping accelerate the U.S. military's hypersonic capabilities, while quickly establishing its role as the defense industry's go-to launch partner for next-generation technology.

There's just so much to do. So, the advances that we've gotten over the last five to ten years have been spectacular. We love the tools. We use them every day. But the question is, is this the whole universe of things that needs to happen? And we thought about it very carefully and our answer was no, there's a lot more to do.

David versus Goliath stories captivate us, especially when David brings a slingshot that looks like alien technology. Enter Stavatti Aerospace, a 25-person firm from Niagara Falls taking on Boeing and Northrop Grumman for one of the most lucrative defense contracts in naval aviation. Their weapon of choice? The SM-39 Razor, a fighter design so visually striking it demands a double-take. The triple-fuselage "Batwing" configuration breaks from a century of conventional aircraft architecture, presenting a form that's more science fiction than traditional aerospace engineering.
