Satellite

Satellites refer to objects that orbit planets or stars. Which of the following is an example of a natural satellite orbiting the earth?

• Moon

• International Space Station (ISS)

• Geosynchronous Orbit (GSO)

• Apogee

Which of the following is not a type of satellite orbit?

• MEO

• DEO

• GSO

• LEO

Which of the following is correct?

• A

• B

• C

• D

What are the shapes of satellite orbits?

i. Perfectly circular

ii. Ellipse

iii. Not uniform

iv. Spiral

• 1 and iii

• ii and iv

• i and ii

• i, ii and iii

For an elliptical orbit, there are two positions referred to as Apogee and Perigee. Based on the picture, identify the position of satellite 1.

• Perigee

• Ellipse

• Perfectly circular

• Apogee

What is the relationship between the height of the orbit and the velocity of the satellite?

• The lower the orbital height of a satellite, the lower the satellite's velocity

• No relation

• The higher the orbital height of a satellite, the lower the satellite speed

• The higher the orbital height of a satellite, the higher the satellite speed

What happens when the height of the orbit increases?

• The speed of satellites decrease due to a lot of space junk in outer space

• The pressure increase

• The gravitational force increase

• The gravitational force decrease

A launch vehicle consisting of one or more rockets is used to send satellites into space. What is the method of sending the launch vehicle shown in the diagram?

• Directly into orbit

• Hohmann transfer orbit

• Staged transfer

• Transfer with ELV

The Space Station (ISS) is a spacecraft that is the place of research for scientists in space. Which of the following statements is not true about the Space Station (ISS)?

• The ISS orbits the Earth every 90 minutes and makes 16 rounds per day

• Allows scientists living in outer space to conduct research in a variety of fields

• It is a collaborative effort between 5 space agencies

• The ISS is located in medium earth orbit (MEO)

Which of the following is not space junk?

• Satellite debris

• A satellite that doesn't work

• Asteroid

• ELV parts that have been used
