Elon Musk said late Saturday that SpaceX should have its first orbital stack of the Starship rocket ready for flight "in a few weeks."

“First orbital stack of Starship should be ready for flight in a few weeks, pending only regulatory approval,” Musk tweeted. 

Musk made sure to note that the flight will need regulatory approval. As of 4 p.m. ET, Musk's tweet had received over 1,100 retweets and over 13,000 likes.

There had been four attempts using prototypes that all exploded.

In May, SpaceX was finally able to get “Starship prototype SN15” to land with no complications. It would set the launch standards for the first orbital stack. 

Musk tweeted in response to TESLARATI, who spoke of the progress SpaceX has accomplished, and how it will be exciting to see history be made at such an accelerated pace.

The complete version of the Starship rocket stands 394 feet tall, which includes its stage booster that is used to launch the spacecraft beyond Earth’s orbit.

The space transportation services company had said that it hopes to launch its Starship rocket atop a booster from its development facility in Boca Chica, Texas, sometime in 2021.

SpaceX’s program wants to use its rocket ships to carry astronauts, deliver large cargo loads to the moon and Mars, and eventually get humans to space at a reachable price.
