Elon Musk's brainchild SpaceX was able to send four astronauts to the International Space Station on Sunday.
Musk was constantly tweeting and retweeting throughout the launch.
U.S. President Donald Trump and President-elect Joe Biden both took to Twitter to congratulate the team responsible for this.
"A great launch...," Trump tweeted.
"...I join all Americans and the people of Japan in wishing the astronauts Godspeed on their journey," Biden tweeted.
SpaceX has experienced both successes and failures in its 18-year history.
On Sept. 28, 2008, the company became the first private company to send a liquid-fueled rocket to reach orbit. The company also became the first private company to send a spacecraft to International Space Station in 2012.
This year has been one of the successful years for the company. SpaceX had successfully sent humans into orbit for the first time on May 30.
However, SpaceX rockets have exploded at least two times - 2015 and 2016 - fortunately, with no human casualty.
