I found this interesting citation on Wikipedia:<br /><br /><b>"Since Shukor is a Muslim, and 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.[1][3] 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 ISS, how to determine prayer times, and issues surrounding fasting. The orbit of the ISS results in one day/night cycle every 90 minutes,[1][12] so the issues of fasting during Ramadan are also addressed."</b><br /><br />How <i>do</i> you find Mecca from space??
