Space company SpaceX unveils the next-generation spaceship 'Starship' and is scheduled to be used on a monthly trip by former President ZOZO Maezawa
SpaceX , a space company led by Tesla CEO Elon Musk , unveiled a new Starship prototype on September 28, 2019. After completion, Starship will be used for the first civilian monthly trip scheduled for 2023.

The height of Starship is 387 feet (about 118m), and it is designed to be reusable. The booster will be equipped with up to 31 raptor engines and the Starship itself will be equipped with 6 raptor engines. The raptor engine was installed in the prototype “Star Hopper”, and the star hopper flight experiment was successful in August 2019.

Normally, titanium and carbon materials are used for the exterior of spacecrafts with a focus on lightness, but the prototype exterior released at the SpaceX experimental facility in Boca Chica, Texas is made of stainless steel that shines in silver. Stainless steel is cheaper than carbon, but it is rarely used in modern spacecraft because of its strength.

Regarding the reason why heavy stainless steel was used for the exterior of Starship, Mask CEO said, “The specific strength of stainless steel is lower than that of carbon material at room temperature, but slightly higher than that of carbon material at low temperature, and stainless steel is much better at high temperature. ' At the prototype public event, he commented, “I love iron,” and invited the venue to laugh.

Starship will be tested for launch and landing within two months, and it is planned to reach the Earth's orbit in about six months, `` If the test program goes smoothly, manned in 2020 It ’s also possible to start flying, ”said Mask CEO.

According to Mask CEO, Starship can carry up to 100 people to the universe, the moon, and Mars, but for Starship to go to the moon and Mars, managing and replenishing fuel is a challenge. SpaceX plans to refuel by connecting the bottom of two Starships, rather than docking and refueling the International Space Station. Regarding this plan, Mask CEO commented, “This is one of the key elements for building a base on the Moon and Mars.”

Starship will be used for commercial space travel in the future. The first project is a lunar orbital trip scheduled for 2023, and several members such as Yusaku Maezawa, former representative of ZOZO, will join this starship.

“This is the most exciting thing I've ever seen. It ’s an incredible job for a great team to build this amazing vehicle. I can work with such a great team. I ’m proud of that. ”
