<p>The Indian Space Research Organisation (ISRO) has successfully mapped the submerged structure of Adam's Bridge, also known as Ram Setu, an ancient bridge between India and Sri Lanka mentioned in Indian religious texts. The researchers used ICESat-2 data from October 2018 to October 2023 to generate a 10-metre resolution map of the full length of the submerged ridge, sufficient to capture details of the size of a train coach.</p>

<p>The detailed underwater map reveals the bridge's continuity from Dhanushkodi to Talaimannar, with a staggering 99.98 per cent of it submerged in shallow waters.</p>

<p>According to a study published in the journal Scientific Reports, ISRO scientists used advanced laser technology from a US satellite to create a high-resolution map of the entire length of the submerged ridge.&nbsp;</p>
