Question

The [x] mission is a highly complex mission, which represents a significant technological leap compared to the previous missions of ISRO. It comprised an Orbiter, Lander and Rover to explore the unexplored [y]. The mission is designed to expand the lunar scientific knowledge through a detailed study of topography, seismography, mineral identification and distribution, surface chemical composition, thermo-physical characteristics of topsoil and composition of the tenuous lunar atmosphere, leading to a new understanding of the origin and evolution of the Moon. 
After the injection of [x], a series of maneuvers were carried out to raise its orbit and on August 14, 2019, following Trans Lunar Insertion (TLI) maneuver, the spacecraft escaped from orbiting the earth and followed a path that took it to the vicinity of the Moon. On August 20, 2019, [x] was successfully inserted into lunar orbit … The Orbiter placed in its intended orbit around the Moon will enrich our understanding of the moon’s evolution and mapping of the minerals and water molecules in Polar regions, using its eight state-of-the-art scientific instruments.

Which unexpected incident took place on September 7, 2019 in relation to the mission referred to in the above passage that was described by the Chairperson of ISRO as ’15 minutes of terror’? 

विकल्प

• Vikram Lander had a hard-landing and communication from the lander to the ground station was lost.

• Vikram Orbiter had disorientation and spiraled out of its intended orbit.

• Vikram Lander got separated from the Orbiter in preparation for landing.

• There was a 15-minute power outage at the ISRO Telemetry, Tracking and Command Network (ISTRAC) when Vikram Lander was about to land.

Answer 1

Vikram Lander had a hard-landing and communication from the lander to the ground station was lost.
