Moon landing help?

the shuttles were apollos.the apollo 11 is the first people on the moon.the crew was buzz aldrin and neil armstrong and another guy who did controls.there was no satellite in 1969 which made them scared.it was if there were harmful germs that cud kill or harm earth.people on the moon.....it goes from apollo 11 to apollo 17.all of those teams had 3 people so that would be 21 people.they used different shuttles too.thats why thwey were called apollo's with numbers because thats howmany shuttles.but not all apollos went to the moon some didnt even make it into space.from apollo 1 to apollo 10 didnt make it to the moon.one of the apollo/saturn v's were going to be able to get to the moon but they got too scared and came back after they got out of the atmosphere.there'll be more apollo's so i hope this helped.by the way they were in space for 3 weeks not 21 hours.they were runing out of air so they went back.there time was up.neil armstrong put a pic of his family on the moon and put a note and said one small step for man,and one giant leap for man kind.
