Raptor Engines and SpaceX's Mars Mission

What is the primary function of the Raptor engine in SpaceX's Mars missions?

• To supply oxygen to astronauts

• To navigate the spacecraft

• To break Earth's gravitational pull

• To provide communication with Earth

Why is methane preferred over kerosene in the Raptor engine?

• Methane produces more residue

• Kerosene is not available on Mars

• Methane is easier to store and maintain

• Methane is more expensive

What is the weight of a Raptor engine compared to a Bugatti Veyron engine?

• One-third the weight

• Twice the weight

• Half the weight

• Three times the weight

What is the potential issue with using kerosene in rocket engines?

• It is too expensive

• It forms a residue that affects reusability

• It is not combustible enough

• It is too heavy to transport

What is a significant challenge in the manufacturing of Raptor engines?

• Designing the engine

• Drawing out a manufacturing design

• Finding skilled labor

• Sourcing raw materials

How often does SpaceX aim to produce a Raptor engine?

• Every 48 hours

• Every week

• Every 24 hours

• Every month

How does 3D printing benefit the manufacturing process of Raptor engines?

• It increases the weight of the components

• It speeds up production and allows design modifications

• It reduces the cost of materials

• It eliminates the need for skilled labor

What is a major advantage of using 3D printers in manufacturing?

• They produce less waste

• They are cheaper than traditional machines

• They can work continuously without breaks

• They require less electricity

What is SpaceX's strategy to minimize outsourcing?

• Carrying out most operations in-house

• Using only local suppliers

• Hiring more employees

• Reducing the number of projects

What is a unique feature of the labor schedule at SpaceX?

• Shifts overlap to maintain continuity

• Employees work from home

• There are no night shifts

• Employees work only on weekends
