Consider the following statements regarding the TransLunar Injection (...
Is rotating, the TLI must be carefully timed to take advantage of the Earth's rotation and achieve the most efficient trajectory.
The TLI is typically performed using a powerful rocket engine, such as the Apollo Service Module's Service Propulsion System.
Once the TLI is complete, the spacecraft enters a trajectory called a Translunar Coast, during which it travels towards the Moon.
The TLI requires precise calculations and adjustments to ensure the spacecraft reaches the correct lunar orbit.
The TLI is a critical maneuver that allows the spacecraft to overcome the gravitational forces of Earth and begin its journey to the Moon.

Consider the following statements regarding the TransLunar Injection (...
The Indian Space Research Organisation (ISRO) recently performed the TransLunar Injection (TLI) to slingshot Chandrayaan-3 towards the moon.
About TransLunar Injection (TLI):
- It is a critical maneuver performed during space missions to send spacecraft from Earth's orbit to a trajectory that will take them to the Moon.
- It is a key step in lunar missions, enabling spacecraft to escape Earth's gravitational pull and travel to the Moon.
- When is it performed? The TLI is performed when the spacecraft is at a specific point in its orbit known as the ‘perigee’ or the closest point to Earth.
- How is it done?
- During a TLI, the spacecraft's propulsion system fires its engines to accelerate the spacecraft.
- The spacecraft gains enough speed to break free from Earth's gravitational pull and embark on its journey toward the moon.
- The amount of thrust and duration of the TLI burn depends on various factors, including the spacecraft's mass, its velocity in Earth's orbit, and the specific mission objectives.
- What happens next?
- Once the TLI is successfully completed, the spacecraft is put on a lunar trajectory, and it will continue its journey to the Moon without further propulsion from Earth.
- After the TLI, the spacecraft typically enters a transfer orbit, which is an elliptical path that intersects with the Moon's orbit.
- The spacecraft continues to travel in its highly eccentric orbit until it reaches the Moon's surface.
- As the spacecraft approaches the Moon, it may perform additional maneuvers, such as lunar orbit insertion (LOI), to enter into lunar orbit or land on the lunar surface, depending on the mission's goals.
- The TLI burn has been performed successfully on many missions to the Moon, including the Apollo missions, the Chang'e missions, and the Artemis missions.
Hence only statement 1 is correct.
