Former Chairman of Indian Space Research Organisation and Secretary to the Department of Space G Madhavan Nair reportedly said that ISRO can even launch 400 satellites in a single go. “We started with ten satellites, then went to 18 or something, then it's 35. Now it's 100. If you make 3 or 4kg satellite, PSLV can take 300 to 400 satellites at a time," said Nair. ISRO launched a record 104 satellites in one go on Wednesday from the Satish Dhawan Space Centre in Andhra Pradesh.
