s and cosmonauts, and spaceflight participants have observed their religions while in space; sometimes publicly, sometimes privately. Religious adherence in outer space poses unique challenges and opportunities for practitioners. Space travelers have reported profound changes in the way they view their faith related to the overview effect, while some secular groups have criticized the use of government spacecraft for religious activities by astronauts.
A signed message from Pope Paul VI was included among statements from dozens of other world leaders left on the moon on a silicon disk during the Apollo 11 mission. Following the mission William Donald Borders, Bishop of the Roman Catholic Diocese of Orlando, told the Pope that the 1917 Code of Canon Law placed the moon within his diocese, as the first explorers had departed from Cape Kennedy which was under his jurisdiction. The Blessed Sacrament has been carried into space at least twice. Three Catholic astronauts on Space Shuttle Mission STS-59 received Holy Communion on 17 April 1994. NASA astronaut Michael S. Hopkins took a supply of six consecrated wafers to the International Space Station in September 2013, allowing him to receive Holy Communion weekly during his 24-week mission. In May 2011, Pope Benedict XVI of the Catholic Church talked to the crew of the Space Shuttle Endeavour while it was in Earth orbit.
Russian Orthodoxy
Russian Orthodox Christmas was celebrated on the International Space Station, on January 7, 2011. Cosmonauts had the day off, but one of the other crew tweeted, "Merry Christmas to all Russia." The whole crew also celebrated on December 25, two weeks prior.
Muslims in space struggle with fulfilling their religious obligations including kneeling and facing Mecca to pray in microgravity traveling at several kilometres per second. The issue first came up when Sultan bin Salman bin Abdulaziz Al Saud, a Saudi prince, flew aboard STS-51-G and again when Anousheh Ansari flew as a tourist to the International space station. In preparation for Malaysian Sheikh Muszaphar Shukor's trip to the ISS in 2007, the National Fatwa Council created "Muslim Obligations in the International Space Station" outlining permissible modifications to rituals such as kneeling when praying, facing Mecca when praying, and washing. In February 2014, the General Authority of Islamic Affairs and Endowment from Saudi Arabia issued a fatwa forbidding devout Muslims from participating as crew members in Mars One's proposed one-way mission to Mars. Speaking for the clerical group, Farooq Hamada explained that, "Protecting life against all possible dangers and keeping it safe is an issue agreed upon by all religions and is clearly stipulated in verse 4/29 of the Holy Quran: Do not kill yourselves or one another. Indeed, Allah is to you ever Merciful."
Judaism
An example of Judaism in space occurred in 2003, when a microfilm Torah and a written copy of the Shabbat kiddush were brought into orbit by Ilan Ramon.
