Heartily congratulating scientists of ISRO, the Congress leader said it is also a "befitting reply to the class of politicians who keep claiming that nothing has happened in the last sixty years".
Azad said the "unprecedented success" in entering the Red Planet's orbit on the first attempt reflected the "unmatched brilliance", remarkable abilities and unflinching commitment of the scientific community.
"Today's achievement has raised our status and esteem in the comity of nations considering the fact that out of the 51 missions, only 21 have succeeded, with none in the first attempt," he said.
"Our head bows to our talented scientists at ISRO for accomplishing this outstanding feat. We are proud of you," the former Union Minister said.
He also said that though it is an event to be celebrated by the nation, it is also a "befitting reply to the class of politicians who keep claiming that nothing has happened in the last sixty years and still never let go of any opportunity to take credit without being willing to share the credit with those who had the vision to nurture world class institutions capable of creating history".
