President Kennedy detailed what college, city and state he was speaking to because in his speech, he reveals that he was once an honorary visiting professor at the school. He also describes the school and the State later on his speech citing their qualities.
It was a mechanism used by President Kennedy to make his speech seem more intimate to the people he was talking to in order to gain greater sympathy and support. Since this direct speech made people feel included in his project, it gained more confidence and restored the hope of the people in the country.
