In 2003, the Israel Space Agency, or ISA, expressed interest in collaborating with the Indian Space Research Organisation, or ISRO, in using satellites for improved management of land and other resources. Israel also expressed interest in participating in ISRO's proposed mission of sending an unmanned craft to the moon. Additionally, the two countries signed an agreement outlining the deployment of TAUVEX, an Israeli space telescope array, on India's GSAT-4, a planned navigation and communication satellite. In 2010, the TAUVEX array was removed from GSAT-4 by the ISRO, and the array was never subsequently launched. The GSAT-4 itself failed to launch, due to the failure of its cryogenic engine.
