    Crew safety apparently. the peroxide is used as a monopropellant in the descent module since the decomposition by products are non toxic (even though the propellant itself is very dangerous).

    Given that the launch was in the daytime in Russia and it was also daytime where I am in Australia it seems unlikely that it's still flying around at night.

    Watch the MS-09 launch, tower jettison was called out at the same time as this launch, just prior to booster sep. ETA- tower jettison was brought forward from the Soyuz TM series to T+115s in order to increase payload.

    Escape tower jettisons just prior to booster separation. The rest of the payload shroud jettisons some time later.

    The RD-108 has four chambers but it's only one engine (not counting the verniers).

    I skydived a few days ago!

    Letting go of the plane is one of the hardest parts. Your brain's kind of asking why you're standing outside an aeroplane at 14,000ft.

    LES was gone so they just had to separate from the rest of the rocket rather than blast free.

    Looks like booster failure so they'll be landing downrange today instead of going into orbit. ETA-booster separation looked pretty rough.

    Because APAS(and now the NASA docking system IDSS) isn't a probe drogue system you can have a docking target inside the docking ring. https://spaceflight.nasa.gov/gallery/images/shuttle/sts-108/html/s108e5112.html

    Dragon 2 and Starliner use the IDSS ports rather than the berthing ports so the HTV delay shouldn't have had any impact on them.

    Soyuz MS-10's due to launch on the 11th October so it's only a reduced crew for a few days. https://en.wikipedia.org/wiki/Soyuz_MS-10

    MS-08 undocking and fly around, https://www.youtube.com/watch?v=8QrmFHkHhdo
  14. Looks like the overwing engines are too close. You could try moving them further out or sinking them into the wing.

    It was the primer colour that they used to paint over with white. To save weight they stopped painting them white and the blue primer colour became a distinguishing feature that they kept. http://www.collectspace.com/news/news-091518a-delta-blue-last-launch.html
