Agar was first introduced into the laboratory in 1881. Since then, microbiologists have depended on agar to create strong jellies. When microorganisms are streaked or plated onto this jellied surface and incubated, individual cells multiply into distinct colonies that scientists can easily observe, select, and propagate for further experiments. Many of the most important findings in biological research of the last 150 years or so — including the discovery of the CRISPR/Cas9 gene-editing tool — have been enabled by agar.4 Agarose, a derivative of agar, is also essential in molecular biology techniques like gel electrophoresis, where its porous gel matrix separates DNA fragments by size, enabling researchers to analyze and isolate specific genetic sequences.

As part of the new plan, the redesigned Artemis 3 mission will give NASA the chance to test at least one lander in the relative safety of low Earth orbit. NASA will attempt to return humans to the Moon during Artemis 4 sometime in 2028, with the potential for another mission as early as later that same year. Per CBS News, the decision comes after NASA's Aerospace Safety Advisory Plan said the agency's existing mission plan was too risky.
