Based on the information provided, we can determine the number of experimental internet satellites launched during the mission. Here's how we can break it down:
1. Total satellites launched: 28
2. Navigation satellites: Half of the total, which is 28/2 = 14 satellites
3. Climate monitoring satellites: 6 satellites
4. Experimental internet satellites: To find the number of experimental internet satellites, we can subtract the sum of navigation and climate monitoring satellites from the total number of satellites launched:
- Total satellites launched: 28
- Navigation satellites: 14
- Climate monitoring satellites: 6
- Calculation: 28 - 14 - 6 = 8
Therefore, the number of experimental internet satellites launched during the mission was 8.
