ISRO MCQ — 52 Practice Questions with Answers

Explanation

The correct matching is: control mode was fully autonomous, the run was completed from an inter-satellite distance of 15 m, and the terminal point was docking. Ground-commanded or semi-autonomous control, a 150 m or 1.5 km starting distance, and endpoints such as power transfer or orbit raising are not the parameters stated for the second SpaDeX docking in the cited fact.

Explanation

The sourced description defines SSLV as a three-stage all-solid launch vehicle meant to place satellites weighing up to 500 kg into Low Earth Orbit. The liquid, cryogenic and reusable-winged descriptions change the propulsion, stage count, payload class or mission profile, so they are not the SSLV description in the cited fact.

Explanation

The cited ISRO release records the halo-orbit insertion at about 16:00 IST on 6 January 2024. The 14:00, 18:00 and 20:00 IST timings are close same-day distractors, but they are not the time stated for the insertion.

Explanation

The correct matching is POLIX with Raman Research Institute and XSPECT with the Space Astronomy Group of URSC. Pairing both payloads with Raman Research Institute ignores XSPECT's URSC link. Reversing the two payloads swaps the institutional responsibilities. Pairing both payloads with URSC ignores POLIX's Raman Research Institute realisation.

Explanation

Statement 1 is correct because ISRO recorded the lander module in a 25 km x 134 km lunar orbit before powered descent. Statement 3 is correct because the date for this orbit update was August 20, 2023. Statement 2 is wrong because the cited orbit was lunar, not an Earth parking orbit.
