In a glowing tribute in 2008, The Indian Woman Scientists Association did not forget to mention that “like most women she also does a tight-rope walk between home and career, between being a mother and a scientist who is dedicated to her job. “We feel Tessy Thomas serves as a role model and an inspiration for women scientists to achieve their dreams and have their feet planted in both worlds successfully,” the group said.Tessy was associate project director of the 3,000 km range Agni-III missile project. She was the project director for Agni IV which was successfully tested in 2011.  Tessy was appointed as the Project Director for 5,000 km range Agni-V in 2009 and is based at the Advanced Systems Laboratory in Hyderabad.  The missile was successfully tested on 19 April 2012. 

In January 2012, Prime Minister Manmohan Singh told the Indian Science Congress that Ms Thomas is an example of a “woman making her mark in a traditionally male bastion and decisively breaking the glass ceiling“.

In 2011, three women scientists won the Shanti Swarup Bhatnagar award, India’s top science prize, compared to 11 from 1958-2010 and one was for Ms Thomas. . “We are all proud of our country. Agni-V is one of our greatest achievements,” she says.
