Sivan graduated with a bachelor's degree in engineering from Madras Institute of Technology in 1980. He then got a master's degree in aerospace engineering from Indian Institute of Science, Bangalore in 1982, and started working in ISRO.
2/n

He earned a doctoral degree in aerospace engineering from Indian Institute of Technology, Bombay in 2006. He is a Fellow of the Indian National Academy of Engineering, the Aeronautical Society of India and the Systems Society of India
3/n

He has previously served as the Director of the Vikram Sarabhai Space Center and the Liquid Propulsion Systems Centre.
Sivan is known for his significant contribution to the development of cryogenic engines, for India's space programme which itself is a marvelous work
4/n

Sivan worked on the design and development of launch vehicles for Indian Space Research Organisation (ISRO). Sivan joined ISRO in 1982 to participate on the Polar Satellite Launch Vehicle (PSLV) Project
That's why he choose the difficult destination where no one even dares
5/n

Sivan's expertise gave ISRO the ability to send 104 satellites in a single mission, setting a world record on 14 February 2017. He was the key person who worked on the technicalities of how the satellites would be placed in orbit.

He also developed the indigenous Geosynchronous Satellite Launch Vehicle MK II, and was part of the team that ideated on the Swadeshi space shuttle.
He successfully achievement led GSLV flight with indigenous cryogenic stage.
7/n

6D trajectory simulation software, SITARA which is the back-bone of the real-time and non-real-time trajectory simulations of all ISRO launch vehicles. He commissioned world class simulation facility in ISRO for mission as well
8/n

He commissioned world class simulation facility in ISRO for mission synthesis and analysis which is used for mission design, sub-system level validation and integrated validation of avionics systems in all ISRO launch vehicles.
9/n

He developed and implemented an innovative day-of launch wind biasing strategy which has made possible rocket launch on any day of the year at any weather and wind conditions

We must be proud of this man who not just made India and @isro proud with his innovation skills and knowledge abilities but also his small town nagercoil and his whole colleague, friends, family members proud as well.
#Chandrayaan2theMoon

Don't forget that @isro lost contact with the #VikramLander just 2.1 km above the lunar surface--so close. Important to remember that the #Chandrayaan2- orbiter and its 8 instruments are safely orbiting the Moon perfectly

@Isro success rate is so high as compared to other space agencies that we expect it to succeed every time, even when the mission is as complex as #Chandrayan2.
#Chandrayaan, #Mangalyaan successes in their first attempts. Let’s be real.

Sivan was exceptional in mathematics, creating a record by scoring 100% in four subjects.Sivan got noticed and a chance of a scholarship at the prestigious (MIT) which boasts of an alumni that includes former president and missile technology pioneer A.P.J.Abdul Kalam.

Father had to sell about a quarter of an acre to send me to MIT," Sivan’s father, the sole breadwinner, owned and cultivated paddy (and other seasonal crops like mango) in the one acre he owned—the only source of income for the family of six

He is also known as the 'Rocket Man' as his significant contribution in the development of cryogenic engines for India's space program
Sivan studied aeronautical engineering at MIT—the same course taken by Kalam—in 1980. Dr Kalam was batch number 4 and I was batch number
