The internet is mocking Elon Musk after he mixed up the moon and Mars.

Musk tweeted out a photograph on Sunday with the caption “Occupy Mars” but Twitter users were quick to point out that the image was not of the red planet, but of the moon during the July 2018 lunar eclipse – a phenomenon known as the blood moon.

“That’s the moon,” said Twitter user Viv, to which Musk responded with two laughing face emojis. He later said “moon too,” adding: “Moon 1st, as it’s only 3 days away & u don’t need interplanetary orbital synchronization.”

It’s not clear whether Musk tweeted the meme in error, or whether it was a deliberate effort to troll some of his followers. According to a reverse image search, Musk’s space firm SpaceX first started using the “Occupy Mars” meme in 2014 – with an actual picture of Mars. It even sells it on merchandise likes T-shirts.
