India has five slots available on its PSLV launcher for missions heading into sun-synchronous orbit between 2015 and 2017, and expects that its more-powerful GSLV Mark 3 rocket, intended for geostationary-orbiting telecommunications satellites, ultimately will be able to accommodate one foreign/commercial launch a year, a senior Indian space official said. The Indian Space Research Organisation took a big step toward deploying is next-generation GSLV rocket in January with a successful flight that marked the first use of an Indian-built cryogenic upper stage. A more-powerful version of this vehicle, called the Mark 3, is what ISRO hopes to use to attract a regular, if modest, commercial market.
