Their reactions came after communication between India's moon lander Vikram and the orbiter got snapped in a last-minute snag when the lander was just 2.1 km away from its designated landing spot on the Moon's South Pole early on Saturday.
Here's what they have tweeted:
Amitabh Bachchan: Moon is 3,84,400 kms and we failed at 2.1 KM that's 0.0005463% of margin. Even this failure is a foundation for new beginnings. Even this failure has a taste of success in it. Kudos to our Scientists and ISRO
Shah Rukh Khan: Sometimes we don't land or arrive at the destination we want to. The important thing is we took off and had the Hope and Belief we can. Our current situation is never and not our final destination. That always comes in time and belief! Proud of ISRO.
