PARLIAMENT QUESTION: THE ADVANTAGES AND BENEFITS OF BHARATIYA ANTRIKSH STATION

1. At a Glance

• Bharatiya Antariksh Station (BAS) is India's planned indigenous space station in Low Earth Orbit (LEO), comprising five modules, to be fully operational by 2035, with the first module (BAS-01) targeted by 2028 [S1][S2].
• Approved by Union Cabinet in September 2024 as part of a revision in scope of the Gaganyaan Programme [S1][S2].
• Implementing body: ISRO under the Department of Space; lead centre for module structure realisation: Vikram Sarabhai Space Centre (VSSC) [S1].
• UPSC relevance: GS-III (Sci-tech, indigenisation, space) — flagship of India's human-spaceflight roadmap alongside Gaganyaan and the 2040 crewed lunar mission vision [S2].

2. Why in the News

• 25 March 2026: Department of Space replied to a Parliament Question detailing the advantages, configuration and progress of BAS [S1].
• VSSC issued an Expression of Interest (EoI) to Indian industries for realisation of the structure of the 1st module of BAS [S1].
• National Level Review Committee has reviewed the overall five-module configuration [S1].

3. Background & Evolution

• 2018: Gaganyaan Programme announced (PM's Independence Day address) — human spaceflight to LEO.
• 2019: ISRO publicly articulated plan for an Indian space station as a Gaganyaan follow-on.
• Oct 2023: PM directed ISRO to set up "Bharatiya Antariksh Station" by 2035 and land an Indian on the Moon by 2040 [S2].
• Sept 2024: Cabinet approval for development & launch of BAS-01 by 2028; revised scope of Gaganyaan includes 8 missions by Dec 2028 (4 original Gaganyaan + 4 BAS precursor missions) at revised outlay ₹20,193 crore [S2].
• 2026 (March): System engineering of BAS-01 and subsystem tech development progressing across ISRO centres; EoI to Indian industry issued [S1].

4. Core Static Facts

• Full name: Bharatiya Antariksh Station (BAS); first module: BAS-01 [S1].
• Number of modules: 5 [S1].
• Orbit: Low Earth Orbit (LEO) [S1].
• Parent Ministry/Dept: Department of Space (DoS); agency: ISRO; structure lead: VSSC, Thiruvananthapuram [S1].
• Cost of BAS-01: ₹1,763 crore for the period 2025–2028 (only first module currently sanctioned) [S2].
• First module launch target: 2028; Full station operational: 2035 [S1][S2].
• Linkage: Part of revised Gaganyaan Programme scope; revised total programme outlay ₹20,193 crore [S2].
• Reviewed by: National Level Review Committee [S1].

5. Multi-Dimensional Analysis

Scientific / Technological - Enables microgravity research in medicine, biotech, material science, fluid physics; supports studies on muscle atrophy, bone density loss [S2]. - Develops advanced life-support systems for long-duration human habitation in LEO [S1]. - Acts as technology testbed for inter-orbital docking, rendezvous, regenerative life support — pre-requisites for deep-space missions [S1].

Economic - Drives high-tech manufacturing ecosystem via EoI route involving Indian industry in structure realisation [S1]. - Aligns with India's target of raising share of global space economy from ~2% to ~10% [S2]. - Catalyses NewSpace start-ups under IN-SPACe framework.

Strategic / Geopolitical - Places India in the elite club (after USA, Russia, China) with an indigenous crewed station [S2]. - Reduces dependence on ISS (US-led, retirement c.2030) and Chinese Tiangong; preserves strategic autonomy in LEO. - Stepping stone for India's 2040 crewed Moon landing vision [S2].

Administrative / Implementation - Phased approval: Cabinet sanction currently restricted to BAS-01 only; subsequent modules require fresh approval [S1]. - Whole-of-government + private industry model: ISRO design + Indian industry build (EoI from VSSC) [S1]. - 4 precursor uncrewed missions by Dec 2028 to validate docking, habitation, life-support tech [S2].

6. Recent Developments (last 12-18 months)

• Sept 2024: Union Cabinet approves BAS-01 + revised Gaganyaan scope (₹20,193 cr; 8 missions by 2028) [S2].
• 2025: System engineering of BAS-01 and subsystem tech development under way in ISRO centres [S1].
• March 2026: VSSC EoI to Indian industry for first module structure [S1].
• 25 March 2026: Parliament Q&A reiterates 2028 launch target for BAS-01 and 2035 for full station [S1].

• Lead ISRO centre for first module structure: Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram [S1].
• Orbit of operation: Low Earth Orbit (LEO) [S1].
• BAS configuration reviewed by: National Level Review Committee [S1].
• BAS is a follow-on of the Gaganyaan Programme [S1].

8. Mains Relevance

• GS-III: Science & Technology — developments and applications; Indigenisation of technology.
• GS-II (peripheral): India and bilateral/multilateral groupings — space diplomacy (Artemis Accords, ISS partners).
• Plausible question stems: 1. "Examine the strategic, scientific and economic significance of the Bharatiya Antariksh Station for India's space ambitions." (15 marks) 2. "Discuss how the revised Gaganyaan Programme integrates the Bharatiya Antariksh Station into India's roadmap for human spaceflight by 2040." (10 marks) 3. "Indigenous space stations are as much about strategic autonomy as scientific advancement. Critically analyse in the Indian context." (15 marks)

9. Related Topics to Study Next

10. Common Errors / Trap Areas

• Wrong year: BAS-01 module = 2028; full station = 2035 — do not conflate.
• Wrong scope of Cabinet sanction: Approval (Sept 2024) covers only BAS-01, not the entire 5-module station [S1].
• Wrong ministry: It is under Department of Space, not MeitY or MoD.
• Wrong agency for structure: First module structure EoI is from VSSC, not URSC/SHAR [S1].
• Confusing with Gaganyaan: Gaganyaan is the crewed LEO mission; BAS is the station. BAS is a scope addition to Gaganyaan, not a separate programme line.
• Cost confusion: ₹1,763 cr is BAS-01 only; ₹20,193 cr is the revised total Gaganyaan + BAS-precursor outlay [S2].
