    Sometimes you get answers to questions you never knew you had asked...
    When I worked in television, we always had to move our dish to a different satellite for the overnight feed when we went off the air.
    We always had to sync with LCS-1 before switching to the new satellite feed.
    I was 0 days old today when I learned what in the hell LCS-1 really was.
    Thanks for the lesson! :)

    Fascinating. I was familiar with the two Echo satellites launched in 1960, but not with LCS-1. The Echo satellites were 30m inflated spheres made of aluminized mylar, and were designed to test radio communication by reflection, and not for calibration. Both satellites re-entered in the late 1960s.

    It might be worth noting that later, Lincoln Laboratory built and launched a series of active communications satellites into orbit. The LES (Lincoln Experimental Satellite) series were far more reliable than almost any others built by for-profit defense contractors. The last in the series, LES 8 and LES-9 were launched into synchronous altitude* in 1976 and in the almost sixty years since then, they never failed.
    *Synchronous altitude but not geosynchronous. An observer on earth sees each of these satellites moving in a figure eight pattern repeating daily.

    And here I thought the inanimate carbon rod had done the most for space exploration.

    So this thought comes up. Does time dilation drastically change with the distance from the star with planets moving at different rates of speed and velocity and or oval orbits that slingshot around the sun.
    Would orbital mechanics limit the rate of time dilation keeping uniform velocities of stars and distance ?

    You don't always need multimillion dollar equipment...Sometimes, you just need really big balls!

    How about using that LASER-propulsion to keep (modern) satellites from falling out of orbit by outfitting them with a "light-sail" or two?

    "It's only flashy in the most literal sense. The world's most boring disco balls." I can't stop laughing at that...

    My first guess, based on the thumbnail, was that it was the kilogram ball. Looking back, I realize it's the wrong element.

    My question after seeing pictures of the NACA sphere and the pseudo sphere is, is it really a Mylar fabric with aluminum skin, as a balloon? And if so, was it inflated once in orbit by a gas, or was it a foam? It could explain why there is a difference in reflectivity.
