Kindly change thread title to ISRO Pad Abort Test, I nearly had a heart attack thinking Boeing or SpaceX pulled a fast one on us all.

Probably via FLP

It will be from a modified sounding rocket launch pad. FLP is occupied with C42 launch campaign at the moment.

Just went to the IP address listed, and nothing bad happened to me - no virus warnings or anything like that. The page seems to feature some kind of dynamic geospatial tracking display in 3D, using both GPS and India's new NAVIC.

 Excuse the ignorance from this layman, how is the module being sent up? And what is the size of it?  The last one launched, was of course the CARE experiment on board GSLV Mark 3-X in December/2014.  And that weighed about 3770kg.  Which vehicle/rocket is carrying it on this mission?

Meanwhile, let's grab all we can on images of the test vehicle, etc. Please post in this thread as I'm sure a lot of us are catching up on this crewed element to their space program.

Are they just testing an abort motor or will they be testing a capsule with parachutes as well? And if there’s a capsule inside the fairing, is it a prototype of the crewed spacecraft seen in drawings and illustrations, or something else?
I'll even excitedly look forward to "flags and footprints" and suborbital missions. Just fly...somewhere.

They will test the abort motor. Capsule already tested with parachutes as part of LVM3-X/CARE mission

If it is ascent abort then yes, but this is Pad abort.

According to information put together from multiple sources, a roughly 3,770-kg trial crew module, aided by four solid-fuelled rockets built around it, will be flown up to a distance of 2.4 km. On firing, the module will be jettisoned and demonstrate a safe descent with the help of parachutes — all this in around three minutes.

Somebody think thats is possible the new spacecraft India has the technology for orbit the Moon?


And in that case, is possible India has the option of participate in the Gateway station?

Crew Module is inside. This the fairing system like Russia and China.

Congratulations to India for the successful pad abort test! For a program that has not yet been officially authorised (the part where they actually launch humans into space), ISRO is making remarkable progress. This blog from 2013 has some interesting information on the PAT. The PAT was planned for 12th plan period from 2012-2018, so ISRO seems to be right on schedule.

Crew Module is inside. This the fairing system like Russia and China.

It is not entirely similar however. The set-up of the abort motors is unusual. There are four (4) nozzles on the tower.
But, there are four (4) nozzles in the fairing as well.

When this thing was launched the four motors inside the fairing fired first, followed a split-second later by the motor driving the four nozzles in the tower. See screenshot below which shows the four nozzles in the fairing already firing, with the tower nozzles about to do so.

The capsule separated from the parachutes before splashdown, giving what looked like a pretty hard landing!

Yes, indeed.  Are we thinking that wasn't supposed to happen?  Otherwise, not sure how the crew wouldn't be injured - at least -- by that.

I'm wondering if that was done to test the robustness/ruggedness of the capsule under impact, as well as to measure the shock loads and their possible effects on internal occupants.

As per plan, there seems to be a retro firing of rockets just before the splash down and a floatation system deployed. Either they were not installed or they did not work.

My jut feel is that they were not installed for this test for some reason and was tested only for parachute deployment

if we refer to this video- a very old animated concept of "Indian Human Spaceflight"- retro firing is planned right after separation of parachutes well above water level.
