Elon Musk took to X to share GIFs from the movie "Step Brothers," comparing himself and fellow billionaire Jeff Bezos to the film's two main characters after Bezos's space company, Blue Origin, successfully launched its first rocket into orbit.

While Jeff Bezos has spent $14 billion to achieve his first space launch, his billionaire rival has built a thriving business, mostly with other people’s money.

Blue Origin's New Glenn finally roared into orbit in the early hours of Thursday, with SpaceX's Starship rocket set to launch hours later.

Blue Origin, the rocket company Amazon billionaire Jeff Bezos founded, notched one of the most substantial successes in its history on Thursday: sending a rocket to orbit.

Despite the failure, Elon Musk appeared to see the bright side, posting: "Success is uncertain, but entertainment is guaranteed!"

Hours after Jeff Bezos's Blue Origin nailed its first-ever orbital mission, SpaceX seized back the spotlight on Thursday as its latest test of Starship, its gargantuan next-generation mega rocket, ended with the upper stage dramatically disintegrating over the Atlantic.

The Amazon founder’s space company marked a major milestone Thursday with the first test flight of its New Glenn rocket.

Blue Origin officials hope to send their heavy-lift New Glenn rocket on its unmanned maiden voyage into space after 1 a.m. EST, with the mission's goal being to reach orbit before returning to Earth.

The agency launched an investigation into the “space vehicle mishap” on Thursday night that forced commercial flights to divert and caused debris to rain toward Caribbean islands.

Jeff Bezos, the second richest man in the world, successfully blasted off a 320-foot-tall rocket ship made by his Blue Origin company from Cape Canaveral, Florida, in the early hours of the morning. It made the company the first to successfully reach orbit on its first launch of an orbital-class rocket.
