HELP !!!
“Scientists have learned a great deal from manned space flights. One unexpected discovery has been that humans are not well adapted to life in space. Life
without gravity causes the fluid in a human body to float upward, which not only creates uncomfortable pressure in the head and chest, but also weakens the leg
muscles. Long space missions can also cause astronauts to develop brittle bones, vision problems, and difficulties eating and sleeping enough.
NASA hopes to send astronauts to Mars in the 2030s. Scientists calculate a trip to Mars would take around 2.5 years. To date, the longest a human has
lived in space is 438 days, a feat achieved by Russian cosmonaut Valeri Polyakov on the Mir space station in 1994–95.”

Answer:

Red Shift is basically a slang term about how machines used to infer light see a red shift compared to previous results on the same galaxy since light traveling farther away is red, this information tells scientists that those objects with red shift are farther away. RST also supports the theory that the galaxy is expanding, as everything is getting farther away from what appears to be a center point, which supports the big bang theory.
