SpaceX Sunday

SPACEX MAKES A NOCTILUCENT CLOUD: NASA’s AIM spacecraft is monitoring a veritable explosion of natural noctilucent clouds (NLCs) around the Arctic Circle. Yesterday, June 29th, SpaceX created an NLC of its own by launching a rocket over Florida. Mike Deep photographed the jellyfish-shaped cloud from the roof of the Vehicle Assembly Building at Kennedy Space Center:

“SpaceX launched a Falcon 9 rocket carrying supplies to the ISS,” explains Deep. “The liftoff time was pre-dawn at 5:42am, which meant the rocket lifted off in darkness and ascended into sunlight at extreme altitude, resulting in noctilucent clouds and a jellyfish plume from the second stage.”

Natural noctilucent clouds form when summertime wisps of water vapor rise to the top of Earth’s atmosphere and crystallize around specks of meteor smoke. Mesospheric winds gather the resulting ice crystals into rippling clouds of electric-blue around the Arctic Circle.

Manmade noctilucent clouds, on the other hand, can form from ice crystals in a rocket’s exhaust. These crystals can catch the rays of the distant rising sun, producing luminous forms in the dark pre-dawn sky. Sample photos may be found herehere and here.

SpaceX’s noctilucent cloud was fleeting. It’s gone now. But the natural variety may still be seen from high-latitude locations in Europe and Canada. Observing tips: Look west 30 to 60 minutes after sunset when the sun has dipped well below the horizon. If you see luminous blue-white tendrils spreading across the sky, you may have spotted a noctilucent cloud.

    I watched the Sunday morning liars, lip,lip,lip service 10, action 0.

    Every show had the exact same sponsors with maybe one exception.

    Captain Obvious sez; they are getting paid by the same people.

    We shouldn’t be surprised with the MSM being good little puppeteers.

      CNN did an interview with an outfit called Judicial Crisis Center on the wee hours. They, among other things, spent $10 M on Neil Gorsach commercials…

      …So naturally, about an hour later, up pops a commercial from JCC with a thinly veiled r/w ad about supporting the next great justice for America.

        Just saw it again on Washington Journal, and it’s not thinly veiled at all. It talked about Trump having already appointed a fair and independent justice commited to the constitution (insert Neil Gorsuch photos), and now there’s another opening, a chance to appoint another great justice, and goes on to show shots of Feinstein, Schumer, Bernie, Durbin, Booker, and Warren and others, saying ‘Like they did before, extremists will lie and attack the nominee, but Don’t Be Fooled, President Trump will appoint The Best of The Best, and with your help, America will get another star on the Supreme Court’

        Judicial Crisis Network, everybody!

    Weather here today the same, high of 90° here at the ranch. Breezy again, too.

    Got new shoes and surprise, surprise, Jill paid for them! She also paid for lunch at the expensive sushi place. When Bob was here I wouldn’t have cared one way or the other because I never paid attention to finances, but now that I’m in charge and there isn’t as much money coming in since they took my SS away from me, I have to learn to manage. But I’m learning, enough to be really happy she paid for my shoes, which I think were $130! Yeah, that’s what I pay for my shoes. I have to baby my stupid feet, can’t just plunk any shoe on them, plus I only have one pair of shoes. I’ll keep my old ones for gardening but always end up wearing the new ones. THIS time I won’t do that because my current shoes aren’t that bad yet. They still look good. I’ll for sure wear them for everything except leaving the house.

    Counterclockwise around to the Tokyo Seoul but it is closed until the 10th so straight back over the viaduct to downtown and the Old Post Office; 64 minutes. The couple from Buenos Aires that I met at the picnic were out bicycling. A dozen+ pigeons wheeled just for exercise, I guess.
