    Interestingly, each 227Kg sat has autonomous collision avoidance tech (first time ever) that will adjust their course to avoid other objects and debris either detected locally or advised via the NASA's object monitoring service. They are made up of 95% demisable components, which means that at de-orbit after their lifecycle they will burn up to dust. This exceeds the minimum spec required, and they plan to get to a 100% demisable design in future iterations.

    Their design also allows for a de-orbit in a few months when active or 1-5 years if passive/failed state through natural orbit decay, this is instead of the normal industry standard 25 years passive orbit decay for low earth orbit in a failed state.

    Raising the bar!

    Musk also alluded to using them to collect space junk on the way out with the collision avoidance system. Guess you can turn it into a collision assurance system.

    Not verified but the concerns regarding the satellites visibility form earth have got some comments that this should only happen during the sun rise / set phase. I think it's going to be one of those things that we will have to get used to if we want this connectivity. Many sci fi movies have this low orbit traffic pictured.

    I did wonder if we need to start planning out launch highways and keeping these area's satellite and debris free but I think that should have happened already..

    Informative if you want to learn about all the different engines and how they compare to the new Raptor engine that is currently on test:

    So has anyone heard anything about Falcon Heavy STP-2? I am planning to go for this last launch as there are no more Falcon Heavy launches until late next year at the earliest :(

    Still a TBD Launch window around June 22 at this stage.
    A SpaceX Falcon Heavy rocket will launch the STP-2 (DSX, Lightsail 2, Formosat-7) mission. The launch date is currently targeted for June 22, 2019 (UTC)

    Unlucky, looking like a drone ship landing rather than land.

    I would wait for a land recovery if your able to wait.

    It's another Falcon Heavy launch, i.e the 2 x side cores land back on pads near the launch site (at the same time) and a sea landing for the 1 x central core downrange.

    I don’t think you would ever see a centre core land back at base with the Falcon Heavy. Usually the centre is at a lower thrust (70%?) until the boosters drop away then it throttles up putting it further down range and it’s going to have a lot of delta V.

    Sorry I got some wrong info from another launch when I was checking the payload / launch window but something does not quite add up.

    They are going to MEO with multiple burns but some sites have mentioned they filed with the FAA a request to land the booster down range at less than 40Km's,

    So apart from the possible midnight launch window this may be better than the Arabsat 6A I saw this year as you may just see 3 booster landings or the booster re-entry burn at lest.

    Will you still get to see any launch ?
    Edit - fingers crossed for you :)

    so much fog, but some of the pictures was so clear compared to other launches. that first stage separation was great footage as it peeled back, beautiful :o
    And the landing of the first stage was some of the best clarity yet (from the on board cameras that is)

    Not spacex related, but a little bit of general space geekery... It seems lego consider the Saturn V kit such a success they're just going bananas on space kits. The new lunar lander is super cool, but they've just announced this years winner of the lego IDEAs competition (where everyday punters come up with designs and lego picks one to develop in house into a commercial kit) and they've selected a pretty awesome prototype for an international space station kit. Cant wait to see what the final product ends up looking like. Particularly love the docked spaceshuttle :).

    (Oh boy do I want that lunar lander. Student budgets suck :p)

    Yep the Luner lander is awesome, as well the ISS. They need to re release the space shuttle and do the Falcon Heavy (which is in review currently)
