Three days ago a Malaysian medical doctor, Sheikh Muszaphar Shukor, launched to the International Space Station aboard Soyuz TMA-11 and will return to Earth aboard Soyuz TMA-10 after nine days aboard the station. Since he is a Muslim, and as his time in space will coincide with the last part of Ramadan, the Islamic National Fatwa Council drew up the first comprehensive guidebook for Muslims in space. The 18-page guidebook is titled "Guidelines for Performing Islamic Rites (Ibadah) at the International Space Station,” and details issues such as how to pray in a low-gravity environment, how to locate Mecca from the International Space Station, how to determine prayer times, and issues surrounding fasting. The orbit of the ISS results in one day/night cycle every 90 minutes, so the issues of fasting during Ramadan are also addressed.
Unfortunately I couldn’t find a PDF of it.
