SpaceX made over 20 launches in  in 2018, but it has also worked on probably bigger and better plans for the future. In the early hours of Christmas Eve, CEO Elon Musk shared a photo of the prototype of his "Starship" under construction.
Starship is the new name for the giant rocket that was previously known under the name "BFR" and which provides SpaceX to people across the moon to Mars and on superfast international flights across space
The photo gives an idea of the rocket size that SpaceX says will be larger and significantly more powerful than the Saturn V rocket that brought Apollo astronauts to the Moon. The nose cone alone seems to be several stories high, overshadowing the work cars that are parked around it.
Musk tweeted that the massive rocket prototype built at the Texas SpaceX test facility has a stainless steel skin. In later comments, he said steel would perform better than lighter carbon fiber materials at high temperatures felt on re-entry
He also added that the skin will "get too hot for colors" and instead have a "stainless steel mirror surface" for "maximum reflectivity".
Musk said SpaceX plans to test the Starship design in 2019 with the test "Hopper" flights, which launch the rocket essentially directly up and bring it back to landing. The test flights will see Musk use three of the company's next-generation "Raptor" engines.
