Also the NASA is entering the advertising campaign of 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 that Stark's communications were disconnected, NASA recommended that field teams "use all resources" to scour the skies and find Stark.

As you can see, Marvel Studios replied to the tweet from NASA saying that he appreciates the help. Also, if you zoom in on one of the tables at the back of the image you can see a label with "Thor" and a hammer. NASA explained in another tweet that THOR is an acronym that stands for "Thermal Operations and Resource".
