In the context of recent developments in Indian space technology, which of the following best describes the primary objective of the Indian Space Research Organisation's (ISRO) Space Docking Experiment (SPADEX) mission?

  1. To demonstrate autonomous rendezvous and docking capability between two small satellites in orbitAnswer
  2. B
    To establish a dedicated satellite constellation for quantum key distribution across ground stations
  3. C
    To map global ocean surface topography using dual-frequency L-band and S-band synthetic aperture radars
  4. D
    To operate solar-powered pseudo-satellites in the stratosphere for continuous regional surveillance

Answer

The primary objective of ISRO's SPADEX mission is to demonstrate autonomous rendezvous and docking capability between two small satellites in orbit.
The Space Docking Experiment (SPADEX) is a twin-satellite mission by ISRO aimed at developing and demonstrating autonomous orbital rendezvous, docking, and spacecraft transfer technologies in Low Earth Orbit. Mastering this capability is vital for complex space operations, including the assembly of the planned Bharatiya Antariksh Station (BAS) and sample return missions.

Step-by-Step Solution

1
Identify the mission in question
The target entity is ISRO's SPADEX (Space Docking Experiment).
Understanding the acronym and target tech helps distinguish its functional objective.
2
Analyze technological components
SPADEX involves two spacecraft (Twin Satellites: Chaser and Target) maneuvering autonomously in Low Earth Orbit (LEO) to dock together.
Docking technology enables joining orbital modules, refueling, servicing, and transferring crew or materials.
3
Evaluate future mission dependencies
Autonomous docking is a foundational prerequisite for setting up the Bharatiya Antariksh Station (BAS) and conducting robotic lunar sample return missions like Chandrayaan-4.
Connecting SPADEX to ISRO's long-term roadmap confirms the correct functional definition.
