Re: Indian Space Program: News & Discussion - Sept 2016

According to a AV report on Youtube[/url], very soon there is a going to be a landing test in Chitradurga in Karnataka. The RLV will be dropped from a height of 3 km by a Helicopter, the onboard system will then help this vehicle to glide and land on runway. That's good, but it would have been nice...

Nice development, but we are also waiting for the second RLV launch. The first one, RLV-D1, was in May/2016. The RLV-D2 is designed to land on a runway, to demonstrate reusability. Awaiting with high eagerness, if not bated breath :)
