Indian space history (APPLE): Identify the false statement about India’s first geostationary experimental communication satellite program (APPLE). Which of the following statements is not correct regarding the experience India gained from the mission?

Introduction / Context:
APPLE (Ariane Passenger PayLoad Experiment) marked a pivotal milestone for India’s early geostationary communication satellite capability. This question tests recognition of what India actually did versus what was provided by international partners during the mission.

Given Data / Assumptions:

• APPLE was launched in 1981 using the European Ariane launcher.
• APPLES’s objectives included in-orbit experiments for communication and operational learning.
• India gained experience in satellite bus subsystems and geostationary operations, not in building Ariane rockets.

Concept / Approach:

To identify the false claim, recall the division of responsibilities: India developed the experimental communication satellite and operating know-how; the European Space Agency supplied launch services with Ariane from Kourou. Therefore, any statement claiming India built the Ariane rocket is patently incorrect.

Step-by-Step Solution:

Verification / Alternative check:

Official histories and textbooks consistently state ESA’s Ariane was used for APPLE’s launch; India did not build Ariane.

Why Other Options Are Wrong:

• Body-stabilized satellite with propulsion/control, attitude/station-keeping, and experimental domestic communications all align with mission learning objectives and in-orbit experiments.

Common Pitfalls:

Assuming launch services equate to building the launcher. Launch provision and spacecraft development are separate domains.

Final Answer:

Building the Ariane launch vehicle used to put APPLE in orbit
