Celestial mechanics  

Do you know that planets move roughly on the same plane?  Do you know that the Earth is moving 100,000 km/h in space?  How can we describe the motions of planets and asteroids?  What about spacecraft?  How do we design its orbit using simple mathematics that you have learnt in secondary school?

Design and operation of artificial satellites and human spaceflight

What are the components of a satellite?  How does it communicate with us in space?  What materials does it made of?  What’s its power source?  What’s the difference between a robotic spacecraft and a human spacecraft?

Planning and cost estimate of space mission  

Do you know how much it costs to launch a 1 kg object to space?  What’s the cost difference between sending a satellite to the Moon and to Mars?  What are the objectives of the Shenzhou missions and its long term goals?  What steps do we need to take in order to send humans back to the Moon?

The future of space exploration and the development of space technology

What missions would you like to see by the year of 2030?  Are we going to have a space hotel in the next 10 years?  Have you heard of a concept called space elevator?  How about living on Mars? When do think it will happen eventually?
