SpaceX CEO Elon Musk trolled for his gaffe "Occupy Mars," he tweeted a picture with tagline Occupy Mars instead of Moon. The picture seems to be of Mars, but it is not. He seems to have mixed up the images of mars with Moon. His post came after the US President Trump's tweet, who went to claim that the Moon was a part of Mars. He was trolled mercilessly; some took the opportunity to correct it, rest created memes about it.
