[  THE TEAM  ]
The Minds Behind Manastu Space:
Innovating Safer and Sustainable Space-Tech
Tushar Jadhav
Co-Founder & CEO
An ex-DRDO scientist who has worked on jet engines for cruise missiles and holds a Master's Degree in Aerospace Engineering from IIT Bombay. With over 10 years of experience in the space and defense sector, he served as the Project Manager for Pratham, India’s first student satellite launched with ISRO’s PSLV-C35 on 26th September - 2016, from the Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh.
Ashtesh Kumar
Co-Founder & CTO
With over 8 years of experience in the space sector, he holds a graduate degree in Mechanical Engineering and a Master's degree in Thermals and Combustion Engineering from IIT Bombay, and led the onboard computer systems for Pratham, India’s first student satellite launched with ISRO’s PSLV-C35 on 26th September - 2016, from the Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh.
From college dorms to global propulsion arena
The Co-founders
2017
The Spark
Two Dreamers, One Dorm Room: It all started with one phone call - "Let's build a space startup." Fresh out of IIT Bombay and having led the Pratham satellite mission, Tushar and Ashtesh had no funding, only a pure self-belief in sustainable propulsion. From college’s aerospace labs to co-founding India's premier green propulsion space-tech startup, the dream first thrusted in their hearts.
2018
The Validation
When Lockheed Martin Said "Yes": Belief is good; but validation is the real fuel - Our turning point came at the India Innovation Growth Programme (IIGP). A panelist from Lockheed Martin backed our vision for safer satellites, awarding us a pivotal grant. This wasn't just money; it was a global nod to India’s capability in Green Propulsion for Satellites.
2020
The Breakthrough
Powering India's Defence” The struggle turned into trust, when we secured our first major contract from DRDO, Ministry of Defence. We delivered the I-Booster, a green propulsion system designed to maneuver 100-500kg satellites. This milestone proved our tech wasn't just a lab experiment; it was ready for national duty.
2024
The Scale
From Zero to Infinity: From 2 founders to a team of a hundred talented minds, we have turned 9 years ever young. Today, with our proprietary green fuel MS289 and flight-proven thrusters like Vyom 2U, we are leading the global shift to sustainable space exploration. We aren't just dreamers anymore; we are the engine behind India's space ambitions, ready to make a dent and thrust beyond.
