Option 1 -> METSAT was India's meteorological satellite launched in September 2002, renamed to honor Kalpana Chawla.
Option 2 -> YOUTHSAT was a joint Indo-Russian satellite for stellar and atmospheric studies, not related to this tribute.
Option 3 -> HEMSAT is not a recognized Indian satellite mission.
Option 4 -> SARAL is a joint Indo-French satellite for oceanographic observations, launched much later in 2013.
Hence, Option 1: METSAT -> This meteorological satellite was renamed Kalpana-1 as a tribute after Kalpana Chawla perished in the Space Shuttle Columbia disaster on February 1, 2003. The satellite had been launched just months earlier in September 2002 and served India's weather monitoring needs -> correct
