Know about the Indian Human Space Flight Endeavor The objective of Human Spaceflight Program is to undertake a human spaceflight mission to carry a crew of two to Low Earth Orbit (LEO) and return them safely to a predefined destination on earth. The programme is proposed to be implemented in defined phases. The pre project activities are progressing with a focus on the development of critical technologies for subsystems such as Crew Module (CM), Environmental control and Life Support System (ECLSS), Crew Escape System, etc., and performance demonstration of major systems through Crew Module Atmospheric Re-entry Experiment (CARE) and crew escape system through Pad Abort Test (PAT). Preliminary design reviews for most of the systems pertaining to CARE for LVM3-X mission and PAT have been completed. Configuration, layout, and structural analysis of Crew Module for CARE mission have been completed. Design of re-entry trajectory for CARE mission corresponding to launch vehicle ascent trajectory has been carried out. Crew Module structure is in advance stage of realisation for flight test in GSLV-MkIII Experimental Mission. Functioning of newly developed Head-end Mounted Safe Arm (HMSA) for solid motors in Crew Escape System was successfully demonstrated. A parachute ejection test with Mortar was carried out at Terminal Ballistics Research Laboratory (TBRL), Chandigarh wherein sequential deployment of pilot parachute and drogue parachute was demonstrated. As part of deceleration system qualification, main and drogue parachutes, in modified and improved pack cover configuration, was drop tested at ADRDE, Agra. Parachute Reefing Line Cutter [RLC] of main parachute was realised and development tests were also carried out. Gas analysers for environment monitoring of crew cabin, cabin lighting system with intensity control and MEMS based barometric sensor have been developed. Wind tunnel testing of Scale model of Crew escape system was completed in National Aerospace Laboratories, Bengaluru. A unique state-of-the-art test facility – Environment Simulation Chamber (ESC) has been realised and commissioned at VSSC for stand-alone and integrated testing of Environmental Control & Life Support System (ECLSS) functional modules and Flight suit systems. A Variable length-to-diameter [L/D] Lithium Hydroxide (LiOH) proto-canister has been realised as part of air re-vitalisation system development. An integrated thermal performance test setup was realised for testing of crew cabin thermal and humidity control system and tests are in progress. In January 2007, ISRO had successfully tested re-entry technologies with the 550 kg Space Capsule Recovery Experiment (SRE-1). The testing of the dummy crew module will be a far more complicated exercise.
