    The pictures showing the aerials protruding radially away from the satellite 
    are not correct. But during launch the aerials were indeed closer to the body 
    to fit with the nose cone. All four aerials would spring open into their 
    unfurled position at separation from the launcher at an angle of 35 degrees 
    with regard to Sputnik 1's main axis. So all the other pictures and models on 
    display show it correctly.
