Researchers demonstrated the first fully 3D-printed, droplet-emitting electrospray engine. The low-cost device can be fabricated more quickly than traditional thrusters, potentially from on board a ...

A group of students forming the UC San Diego chapter of the organization known as Students for the Exploration and Development of Space represented the Jacobs School of Engineering when they conducted ...

In the fall of 2023, NASA hot fire tested an aluminum 3D printed rocket engine nozzle. Aluminum is not typically used for 3D printing because the process causes it to crack, and its low melting point ...

One of these nine Rutherford engines used during the May 2022 There And Back Again mission could return to space later this year. Photo: Rocket Lab Reusability is the key to 21st century spaceflight, ...

You’re exploring for precious metals on the moon but your lander’s engine needs a replacement part and that’s making it a little hard to concentrate. So, you do what anyone would do in the ...

Although today’s rocket engines are advanced and powerful, they tend to rely on traditional — and naturally volatile — fuels. Firehawk Aerospace has a safer and more stable new solid fuel, new engines ...

It's a pretty exciting time to be a space nerd right now. Agencies around the world recently came together to launch the most advanced telescope ever into orbit, startups are promising increasingly ...
