Also the NASA is entering the advertising campaign for the latest Avengers movie. The American space agency wants to help save Tony Stark from his difficult situation, seen in the new trailer of Avengers: Endgame.

In an epic exchange of words on Twitter, the agency offered some advice on how to save Stark. He advised the rest of the Avengers to try to pick up a Stark-type signal "Avengers, we have a problem". In the event Stark's communications were disconnected, NASA recommended that field teams "use all the resources" to scour the skies and find Stark.

As you can see, Marvel Studios responded to NASA's tweet saying it appreciates the help. Also, if you zoom in on one of the tables in the back of the image you can see a label that says “Thor” and a hammer. NASA explained in another tweet that THOR is an acronym for "Thermal Operations and Resource".
