He took to twitter and was visibly impressed by ISRO.
"Yeah, awesome achievement by ISRO. Very impressive!," Musk, the maverick technology entrepreneur, wrote on twitter in reply to a question from Twitter user @Floydilicious. "They are doing India proud," Musk tweeted again.
However, later on, he tweeted something which posed a challenge to ISRO.

Musk's daylight rocket launch is a challenge for ISRO as SpaceX is trying to push the boundaries in space innovation by creating technologies to reduce space transportation cost, and has developed reusable launch vehicles.
The reusable technology of SpaceX is a major challenge for ISRO which has an edge over western countries when it comes to the cost of launch.
Though ISRO too is developing its own reusable technology, it might not match the pace of SpaceX.
The present low-cost edge of ISRO over its competitors will remain only if it innovates at a rapid pace.
