Eco-friendly alternatives to fossil fuels are venturing beyond Earth—and into space.

Cornell researchers have harnessed a chemical reaction typically used in rocket fuel ignition to create a ... forming carbon tubes with a unique abundance of five-membered carbon rings, unlike ...

We are fascinated by the hybrid rocket engine which [Ben Krasnow] built and tested in his shop. It is actually using a hollow cylinder of acrylic as the fuel, with gaseous oxygen as an oxidizer.

The trials verify that the fuel can survive the harsh environment of a nuclear rocket reactor. Up until now, the main way of propelling spacecraft has been through chemical rockets. To be fair ...

Using a chemical reaction inspired by rocket fuel ignition, Cornell researchers ... the hypergolic reaction ignites, forming carbon tubes with a high concentration of reactive molecular rings ...
