An electrospray engine applies an electric field to a conductive liquid – generating a high-speed jet of tiny droplets that can propel a spacecraft. These miniature engines are ideal for small ...

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 ...

Those tiny colorful dinosaur toys that grow bigger underwater might hold the key to protecting astronauts as they journey through space.

Scientists have identified water as one of the most effective materials for blocking radiation. Water is dense and contains ...
