To solve this problem, we need to fill in the missing numbers by skip-counting by 3. This means we start at a number and add 3 to get the next number in the sequence.
Let's follow the path from the rocket to Saturn step-by-step:
1. The first number is
3.
2. Add 3 to 3: $3 + 3 = \mathbf{6}$. (This goes in the first empty circle).
3. The next number given is
9. Let's check: $6 + 3 = 9$. Correct.
4. Add 3 to 9: $9 + 3 = \mathbf{12}$. (This goes in the next empty circle).
5. The next number given is
15. Let's check: $12 + 3 = 15$. Correct.
6. Add 3 to 15: $15 + 3 = \mathbf{18}$. (This goes in the next empty circle).
7. The next number given is
21. Let's check: $18 + 3 = 21$. Correct.
8. Add 3 to 21: $21 + 3 = \mathbf{24}$. (This goes in the next empty circle).
9. The next number given is
27. Let's check: $24 + 3 = 27$. Correct.
10. Add 3 to 27: $27 + 3 = \mathbf{30}$. (This goes in the next empty circle).
11. The next number given is
33. Let's check: $30 + 3 = 33$. Correct.
12. Add 3 to 33: $33 + 3 = \mathbf{36}$. (This goes in the next empty circle).
13. The next number given is
39. Let's check: $36 + 3 = 39$. Correct.
So, the missing numbers in order along the path are: 6, 12, 18, 24, 30, and 36.
Final Answer:
The missing numbers to write in the circles are:
6, 12, 18, 24, 30, 36
