On Wednesday, March 19, 2014, NASA approved the first phase A funding for the joint US/India SAR mission called NISAR, which will fly in about 2019. Phase A is when NASA fully commits to the mission and all funds are identified and put on the books. Costs will be shared jointly between the two countries. The last US civilian SAR satellite mission was the SeaSat SAR from 35 years ago, where the above image is from this mission. As soon as a website for NISAR becomes available, I will post it. My thanks to Ben Holt and Paul Rosen of JPL for this information.
