Examine the role of international mega-science collaborations in advancing India's basic research ecosystem.

Mega-science projects such as particle colliders and giant telescopes cost more than one nation can fund alone. India has joined several of them: CERN, where it has been an Associate Member since 2017 [1], and also FAIR and the Thirty Meter Telescope [3]. This gives India a place in frontier science at a fraction of the cost. The gains are real, but they are uneven.

Role in advancing basic research

• Access to frontier facilities: DST's Mega Facilities for Basic Research scheme funds India's part in CERN's CMS and ALICE experiments, Fermilab's neutrino experiments and Indian beamlines at Elettra, Italy [3].
• Scientific recognition: Indian teams built ALICE's Photon Multiplicity Detector. Indian researchers shared the 2025 Breakthrough Prize awarded to the LHC experiments [4].
• Engineering capability: BARC and RRCAT supplied superconducting-magnet, cryogenic and beam-instrumentation parts for the LHC [4]. India's in-kind contribution rose from 34.4 to 60.4 million Swiss francs [2].
• Human capital: Associate membership lets young Indian scientists and engineers work on CERN projects and bring that knowledge back to Indian programmes [1].
• Industry and diplomacy: Indian firms can now bid for CERN tenders [1][5]. As a founder-member of FAIR and with a roughly 10% hardware share in TMT, India has a say in how these projects are run [3].

Limitations

• Weak industrial return: India pays about ₹50 crore a year to CERN [1]. Yet DST has had to set up a separate tender portal just to steer Indian firms towards CERN contracts [5], which suggests few firms take part.
• Thinly spread funding: One scheme pays for CERN, FAIR, TMT and INO together [3], so these projects compete for the same budget.
• Weak domestic base: Skills gained abroad can be lost to India if there are no home facilities, such as the India-based Neutrino Observatory [3], to use them.

Way forward

• Widen tender outreach to MSMEs, so the fee comes back to India as orders.
• Judge the scheme by the skills and industrial capacity it builds, not only by how many papers Indians co-author.
• Pair every overseas project with an Indian facility that uses the same skills.

Mega-science collaborations have moved India from supplying parts to sharing in discovery. To turn this access into lasting capability, India should back its fees and in-kind work with outreach to industry and with facilities at home. That would serve Article 51A(h)'s duty to develop scientific temper and SDG 9's goal of building innovation.
