{"result":"******************************************************************************\n Revised: Oct 20, 2026    Chandrayaan-2 Orbiter Spacecraft / (Moon)       -152 \n\n NOTE: This is the ORBITER trajectory. The lander (\"Vikram\") separated from \n       the orbiter on 2019-Sep-02 07:45 UTC. The LANDER trajectory ID is -153.\n\n PURPOSE\n  The primary objective of ISRO's Chandrayaan-2 is to demonstrate the ability \n  to soft-land on the lunar surface and operate a robotic rover on the surface. \n  Scientific goals include studies of lunar topography, mineralogy, elemental \n  abundance, the lunar exosphere, and signatures of hydroxyl and water ice.\n\n BACKGROUND\n  Chandrayaan-2 launched 2019-July-22 @ 09:13 UTC from Satish Dhawan Space \n  Centre on Sriharikota Island, India. Launch vehicle was a GSLV-MK3.\n\n  Mission consists of an orbiter, a lander (\"Vikram\") and a rover (\"Pragyan\")\n\n  After launch into Earth parking orbit (170 x 40400 km altitude), a series\n  of maneuvers will progressively raise the apogee of the spacecraft until \n  a subsequent trans-lunar injection burn. Injection to lunar transfer orbit\n  will occur 2019-Aug-14.\n \n  It was inserted into an initial elliptic lunar orbit on Aug 20 \n  (114 x 18072 km) and the first of a sequence of maneuvers executed,\n  lowering apoapsis to 4412 km.\n\n  The orbiter was eventually placed in a 119 x 127 km nearly circular polar\n  orbit after a series of engine burns.\n\n  The lander subsequently separated on 2019-Sep-02 07:45 UTC and will touch\n  down at predetermined site close to the lunar south pole.  \n\n  Touchdown is to occur 2019-Sep-07 on a high plain between two craters, \n  Manzinus C and Simpelius N, about 70 degrees south of the equator.\n\n  [NOTE: landing failed, lander & rover were lost]\n\n  The orbiter mission covers 1 year, in a 100-km circular polar orbit.\n\n  The six-wheeled Pragyan rover, whose name means \"wisdom\" in Sanskrit, will\n  be deployed from a ramp after landing. It is solar-powered and capable of \n  traveling up to 500 meters on the lunar surface at a speed of 1 cm/s. \n\n  The lander/rover missions are planned for 14-15 days (1 lunar daylight\n  interval).\n\n SPACECRAFT DETAILS\n  Launch mass       : 3850 kg\n  Lunar orbital mass: 2379 kg (solar arrays ~1000 W\n  Lunar lander  mass: 1471 kg (solar arrays ~ 650 W)\n  Rover mass        : 27 kg   (solar arrays ~  50 W)\n\n TRAJECTORY: \n  This is a merge of post-launch trajectory solutions fit to tracking data \n  through 2026-Oct-18, with a prediction thereafter.\n \n  Trajectory name                             Start (TDB)        Stop (TDB)\n  ----------------------------------------- ----------------- -----------------\n  ch2o_spk_190722-[200901_od*]_v*_dsn.V0.*  2019-Jul-22 09:31 2020-Jun-01 09:01\n  ISRO_CH2*-OD*                             2020-Jun-01 09:01 2026-Nov-27 10:00\n*******************************************************************************\n","signature":{"version":"1.2","source":"NASA/JPL Horizons API"}}
