Q. Consider the following statements about the Quantum Satellite:

1. Quantum satellite is also known as nanosatellite
2. India launched the world’s first quantum satellite called Micius

Which of the above statements is/are correct?
Answer: Neither 1 nor 2
Notes: Satellites are classified on the basis of weights:
Small satellites or minisatellites- 100 to 500 kg
Microsatellites- 10-100 kg
Nanosatellites- One to 10 kg
Picosatellite- 100 gm to one kg
Femtosatellites- 10 to 100 grams
First statement is incorrect because Quantum satellite is not a microsatellite.
Second statement is also incorrect because China launched the world’s first quantum satellite called Micius. Micius is a 600 kg satellite which has been put into Earth orbit around 500 km above ground. QUESS (Quantum Experiments at Space Scale) is a Chinese minisatellite to establish a space platform with long-distance satellite and ground quantum channel, and to carry out a series of tests about fundamental quantum principles and protocols in space-based large scale.
