Q. With reference to Trans Lunar Injection (TLI) consider the following statements:
1.It is a maneuver that involves slowing down a spacecraft’s velocity to keep it in a stable orbit around the Earth.
2.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. 
Select the correct statements using the codes given below:

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: B
Notes:

Explanation –

Statement 1 is incorrect. TLI is a critical maneuver in space travel that involves propelling a spacecraft out of Earth’s orbit and setting it on a trajectory towards the Moon. This maneuver is a significant step in lunar missions and is used to transfer spacecraft from the Earth’s vicinity to the Moon.

Statement 2 is correct. 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.
