GRID FINS OF ROCKET
Launch of China's Long March-4B rocket from the northwest of the country earlier this week included the use of grid fins to guide and locate fallen debris from the space vehicle more accurately than before.
The grid-fin system started working after the first and second stages separated. It guided the first stage back to landing areas and transmitted flight information to ground stations, narrowing the range of the landing areas by more than 85 percent.
