    How is it possible that the Epoch 138.xxxx element set implies that 
    NextSAT and ASTRO are mated, whereas your later observation shows 
    them as over a kilometer apart? I can think of two explanations:
    1) Inaccuracy of the elements; and
    2) They mated and subsequently were separated for another test.
