He said, “Still about 45 kg of fuel is left; we are hardly using the fuel, fuel requirement is very small. Originally, with the kind of fuel we had carried, we were not expecting that we will be able to complete the mission for more than six months. Now it will be surviving for many years.”“Right from launch till the spacecraft was inserted into the desired orbit, many difficulties could have been encountered. In which case we would have spent more fuel but it didn’t happen right from the beginning through the whole process,” he said.
