It would be a 10 kW satellite with 26 C band and 18 Ku band transponders with a 15 years of expected life. It was scheduled for launch in 2015.[9] On January 10, 2014, JSAT announced that it had signed a launch service contract with SpaceX for the launch of JCSAT-14 aboard a Falcon 9 rocket. The expected launch date was the second half of 2015.[10] But the failure of Falcon 9 Flight 19 meant a delay of at least six months on the launch.[3] On March 14, 2016 SSL delivered JCSAT-14 to the launch site, at Cape Canaveral Air Force Station, for launch processing and integration.[12] JCSAT-14 was launched on May 6, 2016 at 05:21 UTC by a Falcon 9 rocket.[3] The next day, SSL announced that the satellite had deployed the solar arrays, was in full control and was performing orbital maneuvers to reach its operational position.[14] Since July 2016, the rechristened JCSAT-2B is commissioned and operational at the 154° East orbital slot.[15] Launch and rocket landing{{Further | Falcon 9 first-stage landing tests#Flight 24: first return from GTO mission}}JCSAT-14 was launched to geostationary transfer orbit on May 6, 2016 at 05:21 UTC, as the 24th mission of a Falcon 9 Full Thrust rocket.[3] The rocket's first stage subsequently landed on the autonomous spaceport drone ship Of Course I Still Love You in the Atlantic Ocean.[1] The first stage of the rocket encountered "extreme temperatures during its reentry into Earth atmosphere" and was subsequently identified as a candidate for reflight, and as a "reference vehicle" for further testing. It was subjected to a series of tests, including a 150-second full-duration engine firing completed on 28 July 2016. Additional tests were planned before SpaceX determines the stage's suitability for reuse on a subsequent launch.[2] SpaceX has since completed at least 7 more full-duration firings of the core, and has indicated that this stage will be used solely for ground testing purposes.{{citation needed|date=March 2017}} See also{{Portal|Spaceflight}}
