Avengers Endgame
Avengers Endgame opens on April 26, 2019Marvel Studios

The Avengers Endgame trailer dropped last weekend and reactions to what is likely to be Marvel's biggest movie were wide and varied. While some looked at Captain America's unwavering message of hope, others saw the deep despair in a defeated Tony Stark who has apparently given up all hope and is ready to die. The trailer opens with Tony Stark recording his final words to Pepper Potts.

The scene is sobering and the weight of Stark's guilt is apparent throughout. This moved hundreds of fans to turn to NASA asking them for help to rescue Tony Stark from wherever he is, adrift in space, on board the Guardians' spaceship with Nebula to help him out.

NASA actually responded to fans asking for help and tweeted out a few tips directly to the Avengers on how they can find Stark. It is a long shot, but anything is possible in a comic book universe.

"Hey @Marvel, we heard about Tony Stark. As we know, the first thing you should do is listen in mission control for "@Avengers, we have a problem." But if he can't communicate, then we recommend ground teams use all resources to scan the skies for your missing man." said the space agency in one of their tweets.

Referencing the "Houston, we have a problem" quote from the 1995 Ron Howard film Apollo 13, the tweet from NASA, was both timely and showed that one of the more serious branches of government can also have a sense of humour.

When a fan noticed another detail in the image posted by NASA in the tweet, things got even more amusing. User @frunkad zoomed into the image and found a nametag that read Thor and a hammer placed next to it and said that NASA found the hammer, to which they replied, explaining that their Thor is also one of their mightiest heroes. Here is the interaction.
