Contribution and Research Study of Astronauts in SpaceX Crew-4 Mission---
Crew-4 studied how improvements to the space diet affect immune function and the gut microbiome, and determine the effect of fuel temperature on the flammability of a material.
Crew-4 continued work on exploring possible adverse effects on astronaut hearing from equipment noise and microgravity and studying whether additives increase or decrease emulsion stability.
The astronauts also investigated microgravity-induced changes in the human immune system similar to aging and tested a novel water-reclamation membrane.
They also examined a concrete alternative made with a material found in lunar and Martian dust.
Welcome of Astronauts of Crew-4 Mission
NASA Administrator Bill Nelson said, “Welcome Home Crew-4!
This international crew has spent on the International Space Station for nearly six months conducting science for the benefit of all.
Their work aboard the orbiting laboratory will help prepare future explorers for future space missions.
Working and living on the space station is the opportunity of a lifetime, but it also requires these explorers to make sacrifices, especially time away from loved ones.
