We had a great day learning about the universe, the Big Bang and the life cycle of stars.
We also learned about natural and manmade satellites.
We discovered that there are many kinds of satellites orbiting the Earth and learned what jobs they do.
We built our own satellites choosing the instruments we wanted, eg. Imaging Spectrometer, and calculated the power requirements (including for the sub-systems). We then had to calculate the size of our solar array based on the power requirements of our satellite.
