Falcon 9 flight 50 launches tonight, carrying Hispasat for Spain. At 6 metric tons and almost the size of a city bus, it will be the largest geostationary satellite we've ever flown.
Very proud of the SpaceX team! Can't believe it's been fifty Falcon 9 launches already. Just ten years ago, we couldn't even reach orbit with little Falcon 1.
But Musk also reminded everyone that the recent success of SpaceX belies the struggle of its early days.
"Just ten years ago, we couldn't even reach orbit with little Falcon 1," Musk tweeted.
Indeed, SpaceX has come a long way.
"A lot of people really only heard of SpaceX relatively recently, they may think Falcon 9 and Dragon just instantly appeared and that's how it always was. But it wasn't," said Musk at the International Astronautical Congress (IAC) conference in Adelaide, Australia, in September.
"We started off with just a few people who really didn't know how to make rockets," the CEO of SpaceX recalled.
