It will probably switch as much as 18,000 lbs to geostationary switch orbit.
That is the second to final mission for the H-IIB, with its remaining mission deliberate for subsequent yr. After that, MHI has been laborious at work on the H3, a totally expendable launch car at the moment underneath improvement that’s particularly aimed toward serving extra business clients with complete launch prices which might be kind of on par with rising opponents like SpaceX for medium heavy payloads.
