The Crew Module Atmospheric Re-entry Experiment (CARE) is an experimental test vehicle for the Indian Space Research Organisation's future ISRO orbital vehicle called Gaganyaan . [1] It was launched successfully on 18 December 2014 from the Second Launch Pad of the Satish Dhawan Space Centre, by a LVM3 designated by ISRO as the LVM 3X CARE mission. [2] [3] Total cost of mission was 155 crore (equivalent to 248 croreorUS$30 million in 2023). Cost of launch vehicle and CARE module was 140 crore and 15 crore. [4]

Characteristics of the vehicle

The crew module was mounted upside-down inside the payload fairing of the LVM3. CARE was made of aluminium alloy with carbon-fiber reinforced polymer (CFRP) panels and had a lift-off mass of 3,735 kg. Its diameter was 3100 mm and its height was 2698 mm. [5] The module had an ablative thermal protection. The side panels were covered with Medium Density Ablative (MDA) tiles and the forward heat shield was made of carbon phenolic tiles. [6] [7] It was powered by batteries and was equipped with six liquid-propellant (MMH/MON3) 100  N thrusters. [8]

The deceleration system consists of two independent chains of parachutes: a primary parachute (31 meters in diameter), a drop parachute (6.2 meters in diameter), and a pilot parachute (2.3 meters in diameter). [9]

Preliminary tests

A practice run of the recovery of crew module was done on 31 October 2014 with Indian Coast Guard ship ICGS Samudra Pahredar. [10]

CARE was launched on 18 December 2014 at 04:00 UTC. The crew module was separated at the intended height of 126 km and a speed of 5300 m/s. It entered a coast phase during which it performed three axis control manoeuvres in order to ensure zero degree angle of attack at reentry.

The ballistic reentry started from an altitude of about 80 km. At this altitude, the propulsion was shut down. The heat shield experienced temperatures around 1,000 degrees C and the capsule experienced deceleration of up to 13 g. [11]

After the re-entry the vehicle performed a descent and splashdown during which an end-to-end validation of the parachute system was performed, including the demonstration of the apex cover separation and the parachute deployment in cluster configuration. The deployment sequence started when CARE had slowed to a speed of 233 m/s. The crew module carried three stages of parachutes, all of which came in pairs. First, both 2.3-meter diameter pilot parachutes came out, followed by the 6.2-meter drogue parachutes, which cut the capsule's velocity down to 50 m/s. Then both main parachutes were deployed at a height of about 5 km. These parachutes, each 31 meters in diameter, were the largest ever made in India. [12]

CARE splashed down into the Bay of Bengal about 600 km from Port Blair in the Andaman Islands and about 1600 km from the Sriharikota launch site. [13] Immediately afterwards the main parachutes were detached. CARE was recovered by the Indian Coast Guard after tracking its signal beacon. The entire duration of the experiment from launch to splashdown was 20 minutes 43 seconds. [14]

After recovery the module was brought to Chennai on 22 December 2014, from where it will be sent to the Satish Dhawan Space Centre for preliminary processing. [15] The module will then be sent to Vikram Sarabhai Space Centre for further study and analysis. [15]

<span class="mw-page-title-main">Space capsule</span> Type of spacecraft

A space capsule is a spacecraft designed to transport cargo, scientific experiments, and/or astronauts to and from space. Capsules are distinguished from other spacecraft by the ability to survive reentry and return a payload to the Earth's surface from orbit or sub-orbit, and are distinguished from other types of recoverable spacecraft by their blunt shape, not having wings and often containing little fuel other than what is necessary for a safe return. Capsule-based crewed spacecraft such as Soyuz or Orion are often supported by a service or adapter module, and sometimes augmented with an extra module for extended space operations. Capsules make up the majority of crewed spacecraft designs, although one crewed spaceplane, the Space Shuttle, has flown in orbit.

<span class="mw-page-title-main">Reentry capsule</span> Part of a space capsule

A reentry capsule is the portion of a space capsule which returns to Earth following a spaceflight. The shape is determined partly by aerodynamics; a capsule is aerodynamically stable falling blunt end first, which allows only the blunt end to require a heat shield for atmospheric entry. A crewed capsule contains the spacecraft's instrument panel, limited storage space, and seats for crew members. Because a capsule shape has little aerodynamic lift, the final descent is via parachute, either coming to rest on land, at sea, or by active capture by an aircraft. In contrast, the development of spaceplane reentry vehicles attempts to provide a more flexible reentry profile.

Liftoff was delayed to 03:15 UTC due to weather issues, and five seconds before launch it was put on hold by the on-board computer due to an engine anomaly, as reported in ISRO's mission livestream. The launch occurred at 04:30 UTC, and the crew module successfully separated from the launch vehicle. The crew module was successfully recovered by the Indian Navy. India is the fourth country, after Russia, the United States, and China, to successfully test this technology.
