Sachin, also a Rajya Sabha member, is expected to attend Parliament when it convenes for a two-week session tomorrow.
"I would also like to congratulate Professor CNR Rao for his achievement," Sachin said.
One of the most prolific chemists in the country, he still spends several hours every day in his laboratory and has published over 1500 research papers on materials science. He has been in the running for the Nobel Prize for many years.
Mr Rao, an outspoken critic of the system, had recently said "I wish in 20 years India will be in the top three or four countries in the world in science. I really want to see India shine."
Mr Rao is the fourth recipient of the Bharat Ratna from the field of science.
