Gazing at the night sky for hours and thinking about outer space, she wondered about the moon, as to how it changes its shape and size; studied the stars and wanted to know what lay behind the dark space.^[6] In her teens, she started collecting newspaper cuttings about any space-related activity and kept track of the activities of ISRO and NASA.^[7]

Mangalyan was one of the greatest achievements of ISRO.^[4] It made India the fourth country in the world to reach Mars.^[4] It was done in 18 months time and at a far lesser cost to the taxpayers - ₹450 crores only.^[4] Her job was to conceptualize and execute the craft's onward autonomy system, which operated the satellite's functions independently in space and responded appropriately to malfunctions.^[4]
