This is the adorable moment a five-year-old girl who dreams of being an astronaut celebrated the SpaceX launch on Sunday night (November 15).

Ryan Serena wore her beloved costume while watching on TV as Elon Musk's Falcon 9 rocket launched from Cape Canaveral, Florida.

The schoolgirl danced with joy as the four astronauts inside the Dragon Crew Capsule-1 were fired into orbit.

Ryan's proud mum, Tammy, from Philadelphia, said: ''Ryan is obsessed with all things space-related and when it comes to space my daughter knows much more than me. I'm so proud of my little human."

Footage shows Ryan wearing a spacesuit costume and dancing with joy as she watched the launch of the spacecraft on TV. The clip begins with the little girl standing in front of the screen, eager to see the rocket fly up in the sky. 

As the spacecraft launches, Ryan jumps and sings as she becomes excited by the launch. She was even holding a piece of paper wishing the four astronauts a safe trip. 

Single-mum Tammy said that Ryan also dreams of becoming an astronaut when she grows up. On movie night Tammy said her daughter will always choose to watch a Space Station documentary. 

The Falcon 9 rocket was launched from Cape Canaveral, Florida, to the International Space Station. The mission was earlier delayed for 24 hours due to the weather conditions around the offshore landing zone. 

The SpaceX Crew Dragon operational flight is carrying three NASA astronauts Michael Hopkins, Victor Glover Michael Hopkins, Victor Glover and one Japanese space flyer Soichi Noguchi. 

The launch was attended by Vice President Mike Pence and second lady Karen Pence.

SpaceX was founded in 2002 by controversial entrepreneur Elon Musk to reduce space transportation costs to enable the colonisation of Mars.
