A miniaturized digital book containing a prayer of Pope Francis will be sent... in space, Saturday.

The message of hope will be put into orbit at an altitude of 525 km by a Space X rocket. It is taken from a speech delivered by the Supreme Pontiff on March 27, 2020, in the midst of the Covid-19 pandemic. The project, called "Spei Setelles" ("satellite of hope" in Latin) is jointly led by the Vatican, the Italian space agency and various Italian institutes.
