The Long March 9 (CZ-9) is a Chinese super heavy-lift launch vehicle under development by the China Academy of Launch Vehicle Technology (CALT). With a planned liftoff thrust of over 5,500 tons and a payload capacity of over 140 metric tons to low Earth orbit (LEO), it will be the world’s most powerful rocket when completed in the late 2020s.

The Long March 9 will be capable of launching missions to the Moon and Mars, and will play a key role in China’s ambitious space exploration program. It will also be used to launch large space stations and other infrastructure into orbit.

Rocket

Rocket is an open-source, web framework for Rust that emphasizes:

• Simplicity: Easy-to-understand syntax and a straightforward design.
• Asynchrony: Concurrency and performance through async programming.
• Type Safety: Rust’s strict type system ensures code correctness.
• Routing: Powerful routing mechanisms for handling HTTP requests.
• Extensibility: Plugins and middleware for customizing the framework.
• Documentation: Comprehensive documentation with examples and tutorials.

Launch Vehicle

Components:

• Propulsion system: Rockets that provide thrust to lift the payload into space.
• Payload: The spacecraft, satellite, or other object being delivered to its destination.
• Guidance and control systems: Components that navigate and direct the vehicle during launch.
• Structures: The framework that supports and protects the other components.
• Fairing: A protective cover that encapsulates the payload during launch and separates once in space.

Types:

• Expendable: Single-use vehicles that are discarded after launch.
• Reusable: Vehicles designed to land and be reused for multiple launches.
• Vertical takeoff and landing (VTOL): Vehicles that take off vertically like a rocket and land vertically like an airplane.

Functions:

• Lift-off: Provide sufficient thrust to overcome gravity and accelerate the vehicle into flight.
• Booster separation: Detach spent boosters when their fuel is exhausted to reduce vehicle weight.
• Payload deployment: Release the payload into the desired orbit or trajectory.

Attributes:

• Payload capacity: The maximum weight of payload the vehicle can carry.
• Thrust: The amount of force generated by the propulsion system.
• Specific impulse: A measure of fuel efficiency.

Reusable Launch Vehicle

A reusable launch vehicle (RLV) is a spacecraft designed to be used multiple times for space launches. Unlike traditional launch vehicles, which are typically discarded after a single use, RLVs are designed to return to Earth and be refurbished for future missions. This can significantly reduce the cost of space access, as the majority of the hardware and infrastructure required for a launch can be reused.

RLVs have been a long-term goal for space exploration, dating back to the early days of rocketry. However, it was not until the development of advanced materials and technologies in recent years that RLVs became a practical reality.

There are two main types of RLVs: winged and rocket-boosted. Winged RLVs are designed to return to Earth using aerodynamic lift, while rocket-boosted RLVs use rocket engines for both ascent and descent. Winged RLVs have the advantage of being able to land at a precise location, while rocket-boosted RLVs are more efficient in terms of fuel consumption.

The most well-known RLV is SpaceX’s Falcon 9 rocket. The Falcon 9 has been used to launch numerous satellites and cargo to the International Space Station, and has successfully returned to Earth for reuse on several missions. Other notable RLVs include Blue Origin’s New Shepard and Sierra Nevada Corporation’s Dream Chaser.

RLVs are still under development, but they have the potential to revolutionize space exploration. By reducing the cost of space access, RLVs could make it possible to launch more satellites, conduct more scientific research, and send humans to Mars and beyond.
