According to the latest news from the National Aeronautics and Space Administration (NASA), the Russian "Alliance" manned spacecraft launched recently launched three astronauts, of which NASA female scientist Kate Rubens will be genetically sequenced on the International Space Station. The first person. This experiment will help to understand the impact of the space environment on the human genome, master the health of astronauts, and detect life in the solar system.
The astronauts on the "Alliance" are Kate Rubens, Russia's Anatoly Ivanish and Japan's Great Western Extension. They will spend two days testing the "Union" upgrade system in Earth orbit. It is expected to arrive at the International Space Station at noon on the 9th and connect with the Lasvert module. By then, the number of space station astronauts will reach six, they will set up the "Expedition 48-49" task force, and carry out more than 250 scientific experiments in the space station within 4 months.
Kate Rubens will conduct genetic sequencing experiments at the space station. She is a Ph.D. in Cancer Biology at Stanford University School of Medicine and entered NASA training in 2009 to become a qualified astronaut. Rubens is very excited about genetic sequencing on the International Space Station. She will use a mini-gene sequencer to perform sequencing experiments to see how this technology changes under microgravity conditions, such as the shape of a liquid sample, how the sample flows into the sequencer, and so on. This experiment can obtain real-time first-hand gene sequencing data, which is helpful to understand the effects of radiation and sleep changes on the human genome, and is of great significance for future research on human diseases and Mars travel missions in space stations.
NASA Johnson Space Center microbiology scientist Sarah Wallace said that the genetic sequencer that can be used in space can also identify microorganisms, diagnose diseases, help to grasp the health of astronauts, and detect the presence of other parts of the solar system. DNA-based life also has potential help.

Rubens will also test the accuracy of a device under microgravity conditions to better understand the effects of gravity on bone cell function and the changes in the cardiovascular system in the space environment. These experiments contribute to heart disease research and new drug development.
