Buenos Aires, Argentina - September 2023 - On 29 September, the Salesian Pio IX house in Almagro received a visit from one of its former students, Engineer Miguel San Martín, who has been working for NASA for years as a key part of the Mars mission. San Martín, accompanied by his wife Susan, shared a moment of dialogue with the students in the courtyard, gave a lecture and visited the house to which he always likes to return. He emphasised that the time he spent in the Salesian house marked his life not only because of the educational excellence he received, but also because of the relationships and friendships he still maintains today. As a message to the young people, he said: “You have to have faith that if you work hard for something you enjoy and that society needs, opportunities will be given to you. And enjoy the process.”
