    You have quite a few years on me.

    Yes Covid smashed my Mother,before she went,didnt want to go anywhere,**** scared it was going to jump out from somewhere and grab her.All her friends thought the same.They used to Zoom each other but not the same.Actually hit the elderly pretty bad.

    Anyway,just looked at an old vid where i dropped a large porker like a sack full of spuds at a measured 250M running flat out.....
    Those were the days
    250M running flat out.
    Were you chasing the Porker or it you?

    'nightmare' road bollards or BOLLICS ?

    Drivers can be good, bad or just who the hell gave them a license?


    A camera helps prove it

    Starlink - Can I grab another 100 Million USD please Elon?

    Sorry boss I forgot to shield them - I wont do it again

    Solar Storm Destroys 40 New SpaceX Satellites in Orbit

    The geomagnetic incident resulted in the Starlink transmitters drifting back into Earth’s atmosphere, where they will burn up, potentially costing the company about $100 million.

    40 of 49 newly launched Starlink satellites have been knocked out of commission. They are in the process of re-entering Earth’s atmosphere, where they will be incinerated.

    Talking about learning the hard way

    $100 Million would have bought a lot of rolls of Al-foil.


    That'll be put down as a Tax loss never fear.

    Typical County Council. They **** up & cannot make a quick decision to remove the ****ers that are causing Damage & possibly physical injuries. The stupid sods shouldn't have installed them without a thorough investigation imho.

    Maybe the workmen & Engineers cannot read a simple measuring tape which are still in Imperial.


    Sack the lot of those ****ers instantly.

    Given there are over 1900 of ‘em up there I can’t see Elon being too worried. And there are plenty more to come. They put up an average of 50 per launch.

    Not a problem with shielding. The satellites are launched into a very low orbit and then slowly moved into the correct orbit using their own 'steam'.

    But the CME heated the upper atmosphere causing it to expand and increase the drag on the satellites. For 40 of the satellites this increased drag resulted in the satellites having insufficient delta V (limited by the reaction mass carried) to reach their operatiomal orbit. This despite being turned edge on to minimise drag.

    The space weather forecast noted the CME but forecast 'minimal effects'. The only feasible way of dealing with this would have been to delay the launch, which would have caused problems with the launch program. I would guess that this is the first time this has happened and they did not know whether it would be a problem or not. Now they know!

    ??? Would there be such a thing as DRAG at those "altitudes"?

    Some days Paul, I feel like I have a few years on Rip Van Winkle.
    EDIT.
    Like today, lugging a 2 wheeled loan trailer around because the draw bar is really short & behind the 2A with it's "Super Power Steering" & 7.50 x 16 tyres., it was quicker to do it by hand & be done with it even though there were slopes involved. The geographical ones not the other sort..


    It ain't easy for "the man on the land these days" especially when that man is on his Pat & 'indoors can't reverse for nuts.. Well certainly not in a 2A, & to obey hand signals.


    I haven't yet persuaded her to try the Army Method. Ya know, the arms outstretched one although it might be a bit easier if I used The Helicopter Hand Signals.

    Yes. It is not very much, but these satellites don't carry much reaction mass either. Starlink satellites use Hall-effect thrusters with krypton gas as the reaction mass for orbit raising and station keeping (from Wikipedia).
