- CAll the three
- DNone
Show answer
Answer: (C) All the three
Let's check whether each space mission supports microgravity research:
(I) Axiom-4 — YES.
Axiom-4 is a private astronaut mission to the International Space Station (ISS) organized by Axiom Space.
India's involvement includes sending an Indian astronaut (Shubhanshu Shukla) aboard this mission.
The ISS provides a microgravity environment, and Axiom missions specifically carry scientific experiments that utilize microgravity conditions. ✓
(II) SpaDeX — YES.
SpaDeX (Space Docking Experiment) is ISRO's mission to demonstrate autonomous docking capability in orbit.
Being an orbital mission, it operates in microgravity conditions and can support/encourage microgravity research.
The technology demonstrated is also essential for future space station operations where microgravity research will be conducted. ✓
(III) Gaganyaan — YES.
Gaganyaan is India's first crewed space mission, planned to send Indian astronauts to low Earth orbit.
Crewed orbital missions are prime platforms for microgravity research — astronauts conduct experiments in biology, materials science, fluid dynamics, and medicine that are only possible in microgravity. ✓
All three missions encourage or support microgravity research.
Answer is (c).
India selected its first astronaut for a private space mission (Axiom-4) and is developing indigenous crewed spaceflight capability through Gaganyaan, marking a major shift in India's human spaceflight program.
ISRO successfully conducted the SpaDeX mission in late 2024, demonstrating orbital docking technology essential for future space stations where microgravity research occurs.
The question tests whether students understand that any orbital mission - whether crewed, robotic, or demonstration - operates in microgravity conditions and can support scientific research.

Microgravity Research in Space
Science And Technology micro-gravity research
Microgravity Research: Why Space Missions Enable Unique Science
Microgravity = near-weightless conditions in orbital free fall
Eliminates gravity-driven effects that mask phenomena on Earth
Critical for materials science, biology, physics research
Available on ISS, orbital missions, space stations
Microgravity occurs when objects are in continuous free fall around Earth. Spacecraft in orbit experience this condition, creating a laboratory environment impossible to replicate on Earth for extended periods.
Microgravity Research Fields
Research Field | Earth Limitation | Microgravity Advantage | Applications |
|---|---|---|---|
Materials Science | Gravity causes settling/mixing | Perfect spherical crystals | Better semiconductors, alloys |
Biology | Cell behavior affected by weight | Pure cellular responses | Disease research, drug development |
Fluid Physics | Convection currents dominate | Surface tension effects visible | Better combustion, heat transfer |
Protein Crystallization | Gravity distorts crystal growth | Larger, purer crystals | Pharmaceutical research |
