We are the “Citlallicue” team, a group of six students who are enthusiastic about space issues. Our team is made up of: two bionic engineering students, two physiotherapy students, one physics student and one medical bioengineering student. We are in the challenge of | Sleep shift scheduling tool. Our intention is to design an application (GALACTIC DREAMX) that is capable of collecting information on the astronaut's health status: nutritional status, physical condition of the musculoskeletal system, and sleep habits. The application, which we will develop in Android Studio, will be based on the results obtained from the survey and will provide a plan that includes nutrition and exercise tips to reduce fatigue and improve sleep quality for both Astronauts and travelers on Earth.
