SSO rideshare mission - CZ-2C/YZ-1S - 2018
« on: 11/08/2017 12:28 PM »
YZ-1B is a simplified version of YZ-1 upper stage. No more known information regarding this mission for now

Some are bound for happiness, some are bound to glory, some are bound to live with less, who can tell your story?

Actually it's the vanilla YZ-1 that can function for 6.5 hours; YZ-1B (the 1S name is from an older report) "usually have a working time of less than 1 hour" (which means it will usually be used as an apogee trim stage for polar/LEO missions, replacing the SM/SMA solid stages and used particularly for 1-2 tonne satellites where the CZ-2C cannot carry them to polar orbits right now; SAST's YZ-3 will have a similar function).

Will it replace the CTS upper stage too??
