Quad is moving leaps and bounds with every passing day, making China nervous. Now, India is deepening space ties with the US, Japan and Australia, its Quad partners. Indian Space Research Organisation (ISRO) last week shipped the S-band Synthetic Aperture Radar (SAR) to US space agency NASA’s Jet Propulsion Laboratory moving the NISAR (NASA-ISRO SAR) mission further. Not only with the US, ISRO is also working with Japan. On March 11, ISRO and JAXA signed an ‘Implementing Arrangement’ for collaborative activities on rice crop area and air quality monitoring, using satellite data. With Australian Space Agency (ASA), ISRO, in February inked an Amendment of the ‘2012 India Australia Inter-Governmental MoU for cooperation in Civil Space Science, Technology and Education’.
