The rivalry between Elon Musk and Jeff Bezos took a new turn last week when a lawsuit between the two fell in Musk's favor.
On Thursday, Bezos' Blue Origin spaceflight company lost the suit it filed to prevent NASA from doing business with Musk and his SpaceX aerospace company. Nobody seemed happier than Musk.
So much so the CEO immediately took to Twitter to troll Bezos with a meme.
See the post below.
The lawsuit decision is the culmination of a battle the two CEOs have been engaged in since April.
Bezos' and Musk's respective spaceflight companies have been vying with each other for a NASA contract to handle its Human Landing System program, which will bring astronauts to the moon as part of NASA's forthcoming Artemis missions.
NASA awarded the $2.9 billion contract to Musk's SpaceX in April and Bezos immediately struck back. After first filing a complaint with the US Government Accountability Office, Bezos then sued, claiming NASA wrongfully awarded the contract and ignored key safety concerns in the process.
Federal Judge Richard Hertling disagreed and sided with Musk and SpaceX.
Musk being Musk, he took to Twitter to throw a bit of mockery at his rival, using a meme from the 1995 action film Judge Dredd in which Sylvester Stallone stars as the ultimate street-justice warrior in a dystopian Earth of the future.
On Twitter, Musk's outspoken fan club relished his dig at Bezos.
But not everyone was amused by two men with enough money to instantaneously solve several of the world's biggest problems locking horns on the internet.
This isn't the first time Musk and Bezos have traded barbs.
The two men are said to have been arch rivals for almost 20 years, since the founding of Blue Origin and SpaceX in 2000 and 2002, respectively, and have shaded each other over everything from patent races to Musk's overtaking Bezos as the richest man in the world.
