Re: Chandrayan-2 Mission

the general mahaul is they are confident of fixing it on the launchpad itself and confidence in publishing the 22 July date.
by tomorrow it will get fixed and some 72 hr kind of monitoring will start.

good to know monitoring sensors are strong and pervasive and could detect such tiny problem.

Re: Chandrayan-2 Mission

probably in 2 months they will launch. no rush, the moon is mostly always there and close by. this is not a comet we are trying to catch.

only issue is the huge VAB needs to be cleared for next GSLV missions , so they will surely not waste time and keep it parked for too long once things are fixed.

>> I was advocating the SAAW launched from helicopter as one option.

they could be launched from fixed wing a/c without violating the 10km line of the LOC. a regular patrol type flight could drop a swarm of SAAW at 35000ft and move along, letting the weapons turn 90' and home in on target.
