Today, Saturday November 26, an uncrewed SpaceX Dragon craft will be launching to the International Space Station. Packed inside the Dragon, which will be launched by a Falcon 9 rocket, will be a pair of new solar arrays for the space station, called International Space Station Roll Out Solar Arrays or iROSAs, as well as a wide range of science experiments and technology demonstrations.
Another experiment being delivered will look into bacteria found in the human gut, called Bacillus subtilis, which helps prevent foodborne diseases and protects gut health. The experiment will see how the DNA of this bacterium is affected by spaceflight, in order to understand more about microbiology in space and to help keep astronauts healthy.
