On March 30th, 2017, Elon Musk, the founder of the SpaceX, Tesla, and The Boring Company launched their first spaceship. This was not long ago and Musk is developing ways to improve life, such as making the hyperloop, electric cars, and spaceships. In September 29th, 2018, he announced the first SpaceX Mars private passenger project. The objective is to send a giant cargo ship to Mars and provide supplies to a base that will have been made. Two years after, it is planning to send human passengers to Mars. He plans for them to explore Mars and get information to start a colony. His project was first called Elon Musk, however, it was changed to Starship, so it would not be so egotistical. The spaceship is named BFR and stands for the Big Falcon Rocket.

 

BFR is the first spaceship that was privately funded by people all around the world. With this money, SpaceX is buying two warehouses, located in California and Texas, so that production of the spaceship can begin. The company will pay $1.38 million for rent in the first year, making the 20-year contract cost $40 million. The company initially planned to build an 80,000-square-foot factory, which will later cover 200,000 square feet with additional construction. SpaceX is expecting to employ 700 people to help launch the rocket.

 

The Big Falcon Rocket is reusable. The estimated total length of the rocket is 122m (400 ft), which is 11% taller than the previously launched spaceship. For the spaceship’s raptor engines, it has a 250 bar Chamber pressure. The throttle’s is capable of going from 20% to 100% thrust and the 2 Sea-level engines will have a 1.3 exit diameter and 1,700 kN Thrust with a 330s lsp(SL) and 356s (Vac). Finally, towards the edge of the backside of BFR, there are 4 vacuum engines that have an exit diameter of 2.4m, which provides a thrust of 1,900 kN and 275s lsp.

 

Elon Musk hosted an event this Monday night. The main purpose of the event was to introduce Yusaku Maezawa, a Japanese billionaire supporting the new Mars mission. He is the SpaceX BFR’s first supporter and because of his support, SpaceX can launch their spaceship as soon as 2023.
