    F9: Intelsat 35e - 3 launches. 10 days, heaviest commsat yet

    Intelsat 35e is the heaviest GTO payload launched by SpaceX to date. No landing - the payload is too heavy. Falcon Heavy will get these in the future. SpaceX is negotiating contracts for commsats massing >7,000 kg.

    Core: 1037
    Static fire: June 29 (Thursday)
    Launch date: July 3
    Launch time: 1937 EDT (2337 UT)
    Stage recovery: NO

    Satellite: Intelsat-35e
    Destination: GTO
    Slot: 325.5ºE
    Satellite bus: Boeing-702MP EpicNG (HTS: high throughput satellite)
    Bands: C-band (43 spots), Ku-band (39 transponders)
    Propulsion: chemical
    Coverage: Americas, Africa and Europe
    Mass: 6,761.1 kg (14,905.6 lbs)

      Standing down today due to a violation of abort criteria, vehicle/payload in good health, next launch opportunity tomorrow, July 4th!

        Once they have an inventory of used booster this kind of launch will be so much more affordable.
        Be interesting to see how the lower cost will change what organizations want to place in orbit.

          An insight into how much operators save was revealed by BulgariaSat's CEO: 40% of their initial $250 million budget.

          That'd pay for a few lattes at Starbucks.

          Confirmation of tonight's attempt. The previous scrubs appear to have been caused by ground side equipment.

                        100% success launching their largest GEO satellite ever, with bigger ones in the pipeline.

                          Thanks @INTELSAT! Really proud of the rocket and SpaceX team today. Min apogee requirement was 28,000 km, Falcon 9 achieved 43,000 km.

                          The extra apogee will make the plane change to equatorial much easier.

                            Which will allow the sat to keep itself positioned longer due to more retained fuel?

                              Absolutely! Years added to the mission so long as nothing breaks or it gets hit by debris. No doubt about it, Intelsat is a very happy customer.

                              This still isn't SpaceX's record over-performance to a GTO apogee. That would be a lighter bird which was pushed to 90,000 km. It also pushed DSCOVR (Deep Space Climate Observatory ) to L1, a gravity well about 1,500,000 km out between Earth and the Sun
