India has achieved remarkable successes in unmanned space missions including the Chandrayaan and Mars Orbitter Mission, but has not ventured into manned space missions. What are the main obstacles to launching a manned space mission, both in terms of technology and logistics. Examine critically.

Key learnings from their answer

• ›Turned abstract S&T concepts into purpose-built diagrams rather than decorative ones: a Sun-Earth Lagrange-point map (L1-L5) to locate Aditya-L1, vertical-vs-horizontal RLV contrast sketches, a Gaganyaan LEO orbit + escape-module sketch, and an mRNA flow (cell/vector -> spike protein -> immune response) paired with a PIR-vs-SIR immune-response-over-time graph -> for any S&T question, draw the actual mechanism/geometry, not a generic box-chart; the diagram should carry information the prose can't, like orbit positions or a response curve over time.
• ›Pulled answers into the present by citing the latest concrete developments - Shubhanshu Shukla's flight and Vyommitra for Gaganyaan, SpaceX's Falcon-9 booster-catch for RLVs, Shukrayaan's 2027 timeline and 'India as 4th country with a dedicated Venus mission', BrahMos strikes dated 10 May 2025 -> tie each static topic to its newest milestone with a date or 'first/4th' framing, which shows the examiner you are current, not textbook-bound.
