ATV-5 Georges Lemaître, of the European Space Agency - interesting video

The fifth unmanned supply vehicle of the European Space Agency, launched this year, was named after a Catholic priest, Belgian Monsignor Georges Lemaître, one of the greatest cosmologists in history. This very interesting ESA video explains why, and includes uncommon footage of the Monsignor explaining his idea of the "primeval Atom".

Remember, the only Mass ever celebrated by Msgr. Lemaître, who died in 1966 while president of the Pontifical Academy of Sciences (of which he had been a member since 1936), was the Traditional Mass. Video below:
