Saber is used to express knowledge or information about facts, skills, or how to do something. Conocer, on the other hand, is used to express familiarity with a person, place, or thing. So, saber is used when talking about knowing information or how to do something, while conocer is used when talking about being familiar with someone or something.

4. The aerospace centers in Houston and Cape Canaveral serve different functions within the field of space exploration. Houston, home to NASA's Johnson Space Center, is the primary center for human spaceflight activities, including training astronauts and coordinating missions to the International Space Station. Cape Canaveral, located in Florida, is home to the Kennedy Space Center which focuses on launching spacecraft and managing unmanned missions. So, Houston is more focused on astronaut training and human missions, while Cape Canaveral is more focused on spacecraft launches and unmanned missions.
