Scientists have called the extremophile bacterium Deinococcus radiodurans “a robust generalist” capable of persevering amid prolonged exposure to everything from toxic chemicals and corrosive acids to desiccating desert heat and subzero temperatures. Colonies of the bacteria have been found occupying the coolant water tanks of nuclear reactors and thriving on the weathered granite of Antarctica’s dry valleys. They have faced exposure to solar radiation and the vacuum of space onboard a European Space Agency satellite and have survived punishing simulations of life on Mars at the German Aerospace Center in Cologne.

There are a lot of reasons that a faster spaceship is a better one, and nuclear-powered rockets are a way to achieve this, according to an article posted on the Conversation website on May 20.

A 3D-printed nuclear reactor core prototype being developed at Oak Ridge National Laboratory is a step toward reaching the goal of creating an advanced, full-sized, 3D-printed reactor by 2023 at the lab.

According to the federal government, certain critical infrastructure industries have a special responsibility during the coronavirus pandemic to continue operations, including the nuclear power industry.
