Process One

What do we already know about your planetary object? How far away is it? Does it have an atmosphere? How does the atmosphere compare to Earth's? Are there moons to explore? What is gravity like? How much would a person weigh on your planetary object compared to on Earth? Can you create a graph of the comparison? Ask and answer as many questions as you can in this exploratory task. The future success of your mission depends on a complete understanding of your object in task one. Use the following links to uncover the data.
