Honorary Rocketeer

 is an unmarked quest in Fallout: New Vegas.

Quick walkthrough
Upon entering the REPCONN Headquarters you will be greeted by a tour guide.

Gladly accept his invitation for the tour by hearing his story to every item and also read all plaques, up to the Solar System room. Then go to the Souvenir shop and storeroom and take all souvenir rockets.

After that you are a certified Rocketeer!
