The Rajya Sabha was adjourned for two days on Tuesday as a mark of respect to former President APJ Abdul Kalam, who died in Meghalaya on Monday.
"The country has lost a true son of India. His contributions to the nation in his capacity as a man of technology, a teacher and a leader will be deeply cherished by a grateful nation," Rajya Sabha Chairman Mohammed Hamid Ansari said.
Kalam was a guide to India's space and missile programmes and his efforts saw India become a front-ranking power in these spheres. His death is an irreparable loss to the country, Ansari said.
Kalam died on Monday evening in a private hospital in Shillong in Meghalaya.
