The European Space Agency joined in on all the memes and jokes around Wednesday's launch of Threads – the new Twitter competitor app from Meta.
The account, which currently has 122,000 followers on the new app, tagged Mark Zuckerberg in a post that asked: "Do you want to start making rockets?"
That quip earned almost 4,000 likes in 24 hours, and seemingly pokes fun at both the Meta CEO and Elon Musk.
The ESA has done several launches with Musk's SpaceX, including with its Euclid space telescope on a Space X Falcon 9 rocket on Saturday.
The success of Meta's Threads, which had already reached 30 million users as of Thursday morning, may have some questioning if Zuckerberg can do well in other fields too.
After all, Musk isn't the only billionaire with a rocket company – Jeff Bezos and Richard Branson have also made trips to space.
Or, the post might just be poking fun at Zuckerberg's app being a Twitter copycat.
Even before Threads — which has prompted Musk's lawyer to send a cease-and-desist letter threatening legal action, accusing it of being a "copycat" — Meta implemented its stories feature similar to Snapchat's.
Plus Instagram's reels took off shortly after TikTok gained popularity.
Either way, the space agency is one of the first companies to gain attention on Threads.
The ESA declined to comment when contacted by Insider.
