JCSAT-18/Kacific1 Mission

Click any button for sharing!

SpaceX is targeting Monday, December 16 for launch of JCSAT-18/Kacific1 from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. The launch window opens at 7:10 p.m EST, or 00:10 UTC on December 17, and closes at 8:38 p.m. EST, 01:38 UTC on December 17. A backup launch window is available on Tuesday, December 17 that opens at 7:10 p.m EST, or 00:10 UTC on December 18, and closes at 8:38 p.m. EST, 01:38 UTC on December 18. The satellite will be deployed at approximately 33 minutes after liftoff.

Falcon 9’s first stage for the JCSAT-18/Kacific1 mission previously supported the CRS-17 mission in May 2019 and the CRS-18 mission in July 2019. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean. Approximately 45 minutes after liftoff, SpaceX’s two fairing recovery vessels, “Ms. Tree” and “Ms. Chief,” will attempt to recover the two fairing halves.

    Mr. Musk, just a peon here with an imaginative dreamy idea. But I love watching everything that you do and am always thinking how to better humanity as well. Why not have high capacity outfitted “drones” help steer, nudge or guide your rockets on return. Such complicated thrusting algorithms on returning rockets could easily be ensured a 100% stability return with large “SpaceX engineered” guiding drones/quad copters stabilizing the rocket during the low/near descent. Just curious! Love the Nikola in you that’s competing with the current Edison! And I’m still curious on why you once changed your twitter profile to Jung…Carl Jung and his other domain of reality is what makes many of us think what Newton’s other, secretive side was aiming at!


    Amazing every time!!!!

    Missed it live due to being in Europe. Great to wake up and watch a successful mission, with drone ship landing. Congratulations!

    I love how SpaceX keeps the 90s style intro video before every stream.

    I wish I was into this stuff when I was younger, I’m about 20 now and I’m just getting into all this

  28. Kwich Zwellbreck

    I watch every rocket start and loving SpceX´s launches most because of great coverage. I know exactly what will happen, what to expect and if I am late I even know that they launched successfully (dont watch failures dont like that).
    Still I sit everytime with excitement, joy and bewilderment and with supressing tears of happiness when the rocket starts successfully.
    I am admitting I am a space geek =)

    How do you know Space X is getting great at its mission? Even technical media no longer bother to inform about successful booster landing :)
    Congrats to the whole team!

  47. Mark Grant

    Those landings are amazing. I’ve visited the one on display at Space X in Hawthorne. These things are truly massive, which makes these even more amazing.

  59. الكوابيس الثالثه

    I have a question about the theory of woven universes the theory of the interconnected universes in the fabric of the universe
    It is the theory of the Swedish physicist Max Tegmark
    It is a theory that talks about universes woven together but separate in the case of time only, meaning they have a different time
    Max Tegmark theory predicts an infinite universe that is infinite
    So I ask you this question, is our universe infinite?
    Is there any scientific evidence for the validity of the theory of woven universes?
    We hope that the space team will seek scientific evidence to support the theory of woven universes
    We hope that you will communicate this question and suggestion to the Space Research Team

    Is that a Mouse at 17:46?

  61. Adriano Dantas

    17:45 is there a rat walking on board?

    I’m guessing the mouse walking along the engine at around 17:47 lives in the “Hollywood basement” that Outer space is always filmed in..
