    I took my son out to watch the ISS (International Space Station) pass by
    at 5:43 this evening. My son saw it first but we weren't sure because
    something else was moving at the same speed. We quickly realized
    yes both objects were moving across the sky. At arms length they were
    about thumb to pinky (spread out) distance apart.
    When we got home I started looking online to see what the second
    object was. Turns out to be STS129, the space shuttle!
    Open these in two different tabs and see how close they are to each other.
    The ISS.

    I don't know how long they will track.
    Well, I know not past 9:30 tommorrow,
    the shuttle is supposed to land.

    I'm sorry about that.

    This must have been a rare occurance, look how close the were.
    Maximum altitude is at ISS 17:44:57 STS 17:45:19 Within 22 seconds
    Altitude ISS 37° STS 38°
    Within 1°
    Azimuth ISS 44° STS 44°
    Same
    Distance ISS 549 km STS 545 km
    Within 4 km.

    ISS = International Space Station STS= The Space shuttle- STS 129

    Yes, That's what I used to find the ISS would be coming over.
    Then when we saw two objects, I tried to get back on that sight
    and it was to busy for the next few hours.

    My cellphone was close enough, but a compass would have helped
    pinpoint the rising direction better. 4 hours later and I'm still excited!

    The difference in distance between you and ISS and between you and STS
    was 4 km. This does not mean they are 4km apart. That would only be
    true if they were on a straight line from you to those objects.

    The mission before this one, we went out to watch the ISS and saw the
    shuttle leading the ISS. Quite a treat and surprise. Although I had my
    camera, the lens was too long to get both in. Yes, you can sort of
    make out the ISS structure with a 500mm lens.

    I understand that, at one time they were docked with each other.

    From a quick calculation, that 1 degree difference in right ascension
    is about 75 miles.
