From our research we found that the most common factors that affect sleep quality is
Shift work, food kinds, working out, jet lags and time zonesا and we tried to solve these problems through our application so that the astronaut would have better sleep quality.
First problem faces the astronauts is food which affects their sleeping schedule directly Food can affect their sleeping cause they are not aware of the food they should eat according to the time of the day as they should prevent sugary food and food containing caffeine before bed time and should prevent food containing melatonin at the beginning of the day because that would affect on their body for the rest of the day. So that, our application will help them to calculate the calories they need and provide them with meal kind and the important element their bodies need. They use some specific devices to work out to prevent muscle loss and bone loss, and from the devices they use is the treadmill which is formally called Treadmill Vibration Isolation System "TVIS", another device is called Cycle Ergometer with Vibration Isolation System "CEVIS", and there is a device which works on weight lifting and its formally called Resistive Exercise Device "RED". And we have some pictures including these devices and how the astronauts are attached to them in a specific way.
Another problem facing the astronauts sleeping schedule is jet lag and different time zones. The launching time of the spacecraft can cause jet lag disorder and other problems if the astronaut wasn't fully awake during it. So the user should use our append enter the launching time 11 days before it comes to design a specific schedule that will adjust his sleeping time so he can function very well during launching and make sure he doesn't suffer from jet lag disorder.
And through our application we hope to achieve sleeping schedule stability so that the astronaut would be able to have better sleep quality which would directly effect on his/her performance during the missions throughout their day and to prevent fatigue risks, and mental and physical illness. So that we also provided our application with a feature that helps the astronauts be aware about their schedule and what kinds of food to eat as recommendations throughout the notifications and alerts the application gives to the astronaut.

All of the challenges can be solved by codes or any other technical solutions using electronics and just some work and development, but sleep shifting challenge is much harder and more difficult in which it works on both:
the part of programming and the human error by editing the whole day routine.
To solve the challenge we decided to build an application by using Android app studio 'Java &XMl programming languages ' to code and Cloud FIreStore as a DataBase for the app to store the information.
Our application is simple to use, first the user will be asked to Register and enter some required information if it is his first time using the app. He will type his name and mission name so the schedule that will be designed later would be specific for him only.
Then He will type other info
as weight, height and age so the app can calculate the required daily calories and nutrition to maintain his health.
He will also enter sleep related information such as number of usual sleeping hours , number and duration of the naps during the day and that To build the perfect schedule for him and make sure he will be energetic and productive all the day with out felling tired or sleepy.
There are some other data that he will type as well, like medical information, if he is taking any kind of medicine "including sleeping bills "
When the user finishs entering his info and clicks register, all the data will be saved to the data base and the user will be moved to the main Activity where he can see his schedule. There will be other tabs , one of them will show his Daily Caloric Needs and an intent of a website that calculate the calories and nutritional information of food. So he can knows the calories in each meal without leaving the app.
Another tab to show some tips and advices to follow during the day in order to help him not being fatigued and avoid having trouble sleeping.
The app will send alerts and notifications to keep up with the schedule. For example : send alerts when the medicine time comes or when it is the exercise time.

We had problems in the stress online to create half of the application before the hackathon, also we got some issues in sending videos as materials due to the internet and unavailable platforms. There were little issues in the mechanism of the online hackathon as it is much better and more easier to interact. But we became able to solve it.
2\
We formed large database from the researchers and info we collected. Also we have reached a huge developments in our application by making new solutions and editing some issues that organizers helped us to do. We knew new people and got new mates with the same passion of us.
We have used data from NASA site and it helped our team a lot to reach much useful information.
This information made us:
- form a suitable back ground of the problems that faces astronauts in sleep shifting.
- Also it helps us to find many useful solutions that we used later as a first data base for our application. Then it became easier to recreate new solutions and routines for astronauts.
a\
At first, we used PDFs available in nasa.gov which contains the food types and products that astronauts use with their meals. Also we found useful info about minerals their bodies need and the things or activities that are forbidden.
b\
Then, collected some photos and videos from the agencies sites and channels. We read some Q and A sheets of astronauts replying to students’ answers which benefited us a lot to understand the sleeping and work out routines. From info available about flights and arrival times we are now able to add some edits in our plan for jet lags and its solutions.
