India for World’s Largest Telescope

IAS Prelims 2023

After protests in Hawaii in the US against the proposed Thirty Metre Telescope (TMT) project, the largest to be built, alternative sites are being explored which includes Hanle in Ladakh (India).

The project, aimed at exploring the universe, was to come up at Mauna Kea in Hawaii. But protests by the locals and indigenous population have stalled the project.

The construction was expected to start on Mauna Kea, Hawaii, in 2015. However, it is now stalled due to the recent decision of the Supreme Court of Hawaii revoking the construction permit on procedural grounds.

The State of Hawaii agencies are working on the permit process following the prescribed procedure by the court. TMT is pursuing the matter in consultation with the University of Hawaii (land lease holder) and other agencies. It seeks to construct TMT on Mauna Kea which is the preferred choice.

However, given the importance of the project, in terms of finance and its scientific value, the project partners are also looking at alternate sites, both in the northern and southern hemispheres. These include sites in Chile, Hanle, Ladakh and others which are all being evaluated for technical and logistical suitability.

It is expected that on-site civil work on the project may be delayed by about 18-24 months. However, work on telescope and observatory subsystems continue across the partnership.

India is a 10 per cent partner in the TMT project, which includes China, Japan, Canada and the US. On the Indian side, the project is being handled by the Ministry of Science and Technology and Department of Atomic Energy.

If the programme comes to India, it will open several doors.

The project is expected to improve employment opportunities for the local people besides development of the region. TMT being the largest optical and infrared telescope in the northern hemisphere will strengthen the domestic programme of the country in this field and lead to several discoveries, which will inspire future generations.

The project will also help develop state-of-the-art high end technologies and expertise in the country.
