ISRO successfully tests Crew Escape System necessary for human spaceflight
3-4 minutes
Indian Space Research Organisation on Thursday successfully tested its Crew Escape System, which is necessary for human space flight. The technology demonstrator is part of a series of tests to qualify the emergency escape system designed to separate and pull the crew module along with the astronauts to a safe distance.

The Indian Space Research Organisation (ISRO) on Thursday successfully carried out a technology demonstration of its Crew Escape System- a crucial technology necessary for human space flight. Today's technology demonstrator is part of a series of tests to qualify the Crew Escape System, which is an emergency escape system designed to quickly separate and pull the crew module along with the astronauts to a safe distance from the rocket or launch vehicle in the case of a launch abort.
ISRO's technology demonstrator test of the Crew Escape System was the first test (Pad Abort Test) which demonstrated the safe recovery of the crew module in the case of any exigency at the launch pad, the space agency said in a press release. Following a five-hour countdown, the simulated crew module along with the Crew Escape System weighing 12.6 tonnes lifted-off at 7:00 AM (IST) at the opening of the launch window from its pad at the Satish Dhawan Space Centre, Sriharikota.
The technology demonstrator was completed within 259 seconds, during which the Crew Escape System along with the crew module flew skyward, then arced out over the Bay of Bengal and floated back to Earth under its parachutes about 2.9 km from Sriharikota. The crew module reportedly reached an altitude of nearly 2.7 km under the power of its seven 'quick acting' solid motors to take away the crew module to a safe distance without exceeding the safe g-levels.
ISRO mentioned that nearly 300 sensors recorded the mission performance parameters during the test flight. Three recovery boards have been deployed to retrieve the module as part of the recovery protocol.

SUCCESSFUL FLIGHT TESTING OF CREW ESCAPE SYSTEM - TECHNOLOGY DEMONSTRATOR
ISRO carried out a major technology demonstration today (July 05, 2018), the first in a series of tests to qualify a Crew Escape System, which is a critical technology relevant for human spaceflight. The Crew Escape System is an emergency escape measure designed to quickly pull the crew module along with the astronauts to a safe distance from the launch vehicle in the event of a launch abort. The first test (Pad Abort Test) demonstrated the safe recovery of the crew module in case of any exigency at the launch pad.
After a smooth countdown of 5 hours, the Crew Escape System along with the simulated crew module with a mass of 12.6 tonnes, lifted off at 07.00 AM (IST) at the opening of the launch window from its pad at Satish Dhawan Space Centre, Sriharikota today. The test was over in 259 seconds, during which the Crew Escape System along with crew module soared skyward, then arced out over the Bay of Bengal and floated back to Earth under its parachutes about 2.9 km from Sriharikota.
The crew module reached an altitude of nearly 2.7 km under the power of its seven specifically designed quick acting solid motors to take away the crew module to a safe distance without exceeding the safe g-levels. Nearly 300 sensors recorded various mission performance parameters during the test flight. Three recovery boats are being exercised to retrieve the module as part of the recovery protocol.

Wait. The Crew module weighs 12.6 tonnes? But the payload to LEO capability of GSLV Mk-III is just 10 tonnes.
Now ISRO plans to replace the L110 stage in the GSLV Mk-III with the SC-200 stage by 2021. That should raise the payload capacity to LEO beyond 12.6 tonnes. So does that mean the Human Space Flight program will have to wait until this new rocket (GSLV Mk IV ?) is human rated? Anybody got any idea how long would that take?
Also, in the CARE experiment in 2014, the crew module (inset) weighed just 3735 kg. So does that mean that the extra 8.9 tonne mass was of the Crew Escape System? That would be a surprise if it is true.

Here you can get a glimpse of the heavy lift vehicle which will be used to carry the crew capsule.

Wait. I just figured out that the needle on top of the HLV-HSP rocket is the Low altitude Crew Escape System that was tested today.
So I cannot understand these news articles stating that the launched payload weighed 12.6 tonnes. That needle weighs 8.9 tonnes?
That is the crew module being pulled along by the crew escape system.

2 Good news and 1 Bad news
Good news 1: HTVE (High Thrust Vikas Engine) set to make its debut. Ground testing completed this Sunday.
Good news 2: SCE-200 engine ready for testing, funding for SC-200 stage (that will replace L110 stage of GSLV Mk-III) already released.
Bad news: Can't say when SC-200 will replace L110.
I really hope L110 replacement can happen by 2021. BTW, that funding for the 10 GSLV Mk-III launches in next 5 years that the government released recently would have to be for the L110 variant, right? So we might see additional GSLV Mk III fly (beyond the 10 approved now) when government releases additional funds for developmental flights of the new configuration of GSLV Mk-III with SC-200 stage in the 2021-2023 period.

That will have 2 ton more fuel and will have higher burning time as well.

ISRO to test reusable launch vehicle soon – Indian Defence Research Wing
2 minutes
SOURCE: Express News Service
The Indian Space Research Organisation (ISRO) will soon carry out another major test for its reusable launch vehicle (RLV) in which the vehicle will be flown to a height of 3 km by a helicopter and let free to land autonomously at an airstrip in Challakere in Chitradurga district.
This would be the second test for the vehicle after the first one in 2016 demonstrated that the RLV could land autonomously in the sea after being taken to an altitude of 65 km.
Talking about the upcoming test, S Somanath, Director of the Vikram Sarabhai Space Centre, said the test will be carried out at the airstrip, owned by the Defence Research and Development Organization within 6 months.
“After this test, we will integrate the vehicle into a new rocket which will take it up into orbit for it to return,” he said. Somanath was speaking at the Aerospace and Defence Manufacturing Show (ADMS), organised by Aeromag Asia and Society of Indian Aerospace Technologies and Industries in the city.

^That would be REX
Following were the experiments to be carried out during the RLV TD program:-
- HEX (Hypersonic EXperiment) Done 2016
- LEX (Landing EXperiment) To be done 2018
- REX (Return EXperiment)
- SPEX (Scramjet Propulsion EXperiment)
But the real challenge will be SPEX. Maybe we will see it only post 2021. And after that ISRO will see if it should go forward with developing a full fledged "Space Shuttle". Long road ahead. All the best to ISRO.
On contrary, I think REX would be more complex in nature then LEX. It would mean that you would have to consider avionics along with fluid dynamics when returning from a suborbital flight. Our first splash down test was from mere 65 km and it was a splash down test. But after LEX when we would be carrying out REX, we would be landing the RLV rather then splashing it down. So I think it would be more of a challenge to us.
