Q. With reference to different types of space missions, consider the following statements:
1.Flybys are spacecrafts designed to get into a lunar orbit and carry out prolonged studies of the Moon’s surface and atmosphere.
2.Landers missions involve the soft landing of the spacecraft on the Moon.
3.Rovers are the missions in which the spacecraft passed near the Moon but did not get into an orbit around it.
How many of the statements given above are correct?
Answer: A
Notes:
Explanation –
Statements 1 and 3 are incorrect. Flybys are the missions in which the spacecraft passed near the Moon but did not get into an orbit around it. These were either designed to study the Moon from a distance or were on their way to some other planetary body or deep space exploration. Rovers are special wheeled payloads on the lander that can detach themselves from the spacecraft and move around on the moon’s surface, collecting very useful information that instruments within the lander would not be able to obtain.
Statement 2 is correct. Landers missions involve the soft landing of the spacecraft on the Moon.
