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 .
All three designs employed a mission module cabin separate from the command module (piloting and re-entry cabin), and a propulsion and equipment module. Martin studied three different reentry module shapes, including a conical capsule vehicle similar to the STG configuration. GE also studied several reentry module shapes.
In March 1965, NASA approved the transfer of the Gemini 2 capsule to the USAF for modification into the first prototype of the Gemini B capsule. [5] On 3 November 1965, the first Manned Orbiting Laboratory (MOL) and Gemini B suborbital test mission was launched. [5] It is the first capsule to ever be flown twice in space. [6]
The VBK-Raduga capsule was a reentry capsule that was used for returning materials to Earth's surface from the space station Mir. They were brought to Mir in the Progress-M cargo craft's dry cargo compartment. For return, the capsule would be substituted for the Progress' docking probe before it left the space station, and then after the ...
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.
The concept has also been used to extend the reentry time for vehicles returning to Earth from the Moon, which would otherwise have to shed a large amount of velocity in a short time and thereby suffer very high heating rates. The Apollo Command Module also used what is essentially a skip re-entry, as did the Soviet Zond and Chinese Chang'e 5-T1.
At 09:17 am, SRE-1 capsule was reoriented for its re-entry into the dense atmosphere. The capsule made its re-entry at 09:37 am at an altitude of 100 kilometers with a velocity of 8 km/s (ca. 29,000 km/h). During its reentry, the capsule was protected from the intense heat by carbon phenolic ablative material and silica tiles on its outer surface.
First the two drogue parachutes were released, which slowed and stabilized the capsule from 500 km/h to 280 km/h. They pulled out the three large main parachutes some twenty seconds later. The capsule of Apollo 15 descends under only two good parachutes. The recovery forces in the area reported that only two of the main parachutes had inflated.
