Archaeologists have recovered artefacts pre-dating the Harappan Civilisation from the site, located in village Kunal in Fatehabad district.
NASA and ISRO inspection is likely to be done in October this year, 2017, Haryana Archaeology and Museums Minister Ram Bilas Sharma said on Monday.
"The recovery of artefacts, estimated to be 6,000 years old, strongly indicated that the civilisation that had flourished in Kunal was in fact the oldest civilisation in the world. The Harappan Civilisation, considered so far to be the oldest civilisation, flourished about 3,500 years ago," the Minister said.
The artefacts recovered included ornaments and pots, apart from spherical structures.
The Haryana government is considering to establish international-level museums at Kunal and Rakhigarhi.
