INO (India-based Neutrino Observatory) and JUNO (Jiangmen Underground Neutrino Observatory) are prominent international scientific initiatives dedicated to the study of neutrinos. These are exceedingly small subatomic particles that exhibit minimal interaction with matter. Due to the rarity of neutrino interactions, larger detection systems are essential for observing sufficient events and obtaining accurate data.
The INO project encountered various setbacks stemming from technical, administrative, and social challenges:
Consequently, the INO project has been stalled for several years.
In contrast, the JUNO project in China, although delayed by roughly five years from its initial target of 2020, has successfully completed its construction. The collaboration unveiled its first scientific findings on November 18 through two preprint papers. JUNO's strength lies in its extensive global partnership, encompassing researchers from numerous countries, including Russia, the United States, the United Kingdom, and others.
Neutrinos exist in three distinct flavors and can oscillate between these states during travel. Nevertheless, the precise arrangement of their masses remains an unresolved issue in physics. This mass ordering is characterized by mixing angles such as θ-12, θ-13, and θ-23. JUNO's recent high-precision measurement of θ-12 may help clarify this enduring mystery.
India's absence from the JUNO collaboration is not entirely understood. A similar trend has been observed previously, such as when Indian teams did not participate in studies concerning lunar samples from China's Chang'e-5 mission. This is particularly surprising given India's strong scientific heritage in neutrino research.
The overarching message is that missing one opportunity can lead to a cascade of missed chances. Future "Big Science" projects will require even more advanced technology, robust institutional capacity, and effective community engagement. Therefore, India must ensure not only scientific readiness but also foster supportive local and administrative environments to engage successfully in forthcoming global research initiatives.
