Elon Musk on Friday shared photos of SpaceX's Starship atop a Super Heavy rocket booster before its first orbital flight.
At about 400 feet tall, it was the biggest rocket ever constructed, BBC News reported.
The construction took place at SpaceX's launch site, Starbase, in Boca Chica, Texas. Musk's photos were the latest in a series he's posted showed the spaceship being stacked together.

CNBC's Michael Sheetz asked Musk what it felt like witnessing the milestone.
"Dream come true," Musk said on Twitter.
Musk said there were four "significant items" SpaceX would need to complete before its Starship orbital launch.
In the next two weeks, the company needed to add "final head shield tiles," add "thermal protection" to the Raptor rocket engines, complete work on "ground propellant storage tanks," and add a quick disconnect arm to the top of the spaceship, Musk said.

The first orbital test of the Starship rocket was expected to last around 90 minutes. SpaceX planned to launch from South Texas and splash down off the coast of Hawaii, according to a May FCC filing.
The spaceship was built to carry both crew and cargo on long-duration interplanetary flights. It's expected to go to the Moon and eventually travel to Mars.
