    Boas!

    Yes, Europa really is sending plumes of water into space
    Galileo's closest approach to Europa brought it within 206km of the moon's surface.

    NASA just found evidence of a plume spewing from Europa — buried inside the data of an old spacecraft
    A gem was hiding in Galileo’s archives

    Lá em cima há planícies sem fim; Há estrelas que parecem correr; Há o Sol e há dia a nascer;
    E nós aqui sem parar numa Terra a girar…

    Ariane chief seems frustrated with SpaceX for driving down launch costs
    “I cannot tell my teams: 'Goodbye, see you next year!'”
    ...
    Like Russia and the US-based United Launch Alliance, the Ariane Group faces pricing pressure from SpaceX, which offers launch prices as low as $62 million for its Falcon 9 rocket. It has specifically developed the Ariane 6 rocket to compete with the Falcon 9 booster.
    But there are a couple of problems with this. Despite efforts to cut costs, the two variants of the Ariane 6 will still cost at least 25 percent more than SpaceX's present-day prices. Moreover, the Ariane 6 will not fly until 2020 at the earliest, by which time Falcon 9 could offer significantly cheaper prices on used Falcon 9 boosters if it needed to. (The Ariane 6 rocket is entirely expendable).
