After Marvel released the trailer for "Avengers: Endgame," on Friday, NASA started to get lots and lots of tweets from concerned fans hoping they'd help get Tony Stark back to Earth.
In the trailer, Stark leaves a final message for Pepper Potts because he's honestly lost hope that he will be rescued, food and water are gone and oxygen isn't far behind it.
Of course, fans were upset, we know that Endgame is going to be full of heartbreak.
NASA decided to respond, you can see the tweet below. They suggest listening over frequencies for his call.
But what if he can't communicate?
They had advice for that too. Scan the skies.
