back to article US spook-sat buzzed the International Space Station

For a little while earlier this month, astronauts on the International Space Station had a spooky companion: a spy satellite that circled just outside its “danger zone”. Dutch satellite-watcher Marco Langbroek (whose day job is at Leiden University) analysed the orbit of USA 276, a spy satellite owned by the US National …

    Those remote workers...

    ... you have to check up on them to see if they're really doing work during paid hours.

      Nah, just a miscommunication back at the spook shack:

      "What? ISIS, not ISS, you idiot!"

    That must have used up some fuel,

    wonder was the ISS checking on the spy sat, or the spy sat calibrating what it could do / see on the ISS,

    does the ISS have a test target for it ?

      Not a lot of fuel though. Reading the source article, it's clearer what the flight pattern was... the two craft orbited a few times very close but on slightly different planes, such that they crossed paths twice per orbit. USA-276 did adjust its speed (and thus altitude) such that it was sometimes underneath and sometimes above though.

      It's not as dramatic as the chosen graph implies - it wasn't flying circles around the ISS in the way you would normally think of it.

      Whose space station could it be that the Americans want to look at and need to do a rehearsal first?

      1. PassingStrange

        I suspect it's more like, "Why not?"

        You never know when you're going to want to do something like that. Plus you know everything about the ISS. So (a) practice it, and (b) find out how much information you can actually gather that way with that sat, and what your analysts can make of it - and what gets missed, as well. Why wouldn't you? Plus it's a great chance to eyeball the outside for damage.

        AC "Whose space station could it be...?"

        As was shown by the perfectly fact-based movie 'Gravity', all the various space stations and most orbital vehicles are in the very same orbit, and separated by only a few km.

        Right?

        /LOL

      I don't recall reading anything about a specific target on it, but it does have target markers near the docking ports to line up incoming resupply runs.

      I did wonder if USA 276 was a SIGINT satellite and was perhaps calibrating it's systems but according to Wikipedia (so taken with a pinch of salt) it's a radar imaging satellite.

      Maybe they were making a 3D model of the ISS, but I'm pretty sure there's cheaper ways for them to do that!

    Space shuttle was photographed by Keyhole spy satellite

    I recently read a fantastic history of the Space Shuttle.

    Arrggh - can't remember the title.

    The book shows how a KH 11 Kennen satellite was manouvered (sp?) to take images of the first Shuttle flight to check for damage before it re-entered. NASA was concerned about tile damage even then.

    Sadly there was no such surveillance of the final flight of Columbia.

    Perhaps this is a similar exercise? Then agian one would imagine if regular resupply missions are taking place then the astronaults will have a good gander attheir new home and check for damage.

    One might imagine the ISS could be used for calibration of the spy sat cameras.

    But again this can be done with a target on the ground - the Tate Modern has an artwork which shows just such a calibration target painted out on the New Mexico desert.

      Re: Space shuttle was photographed by Keyhole spy satellite

      The history of the Shuttle with the description of KH sat squared photography was probably "Into The Black"

      Similar imagery was taken of Skylab, which allowed NASA to appropriately tool and equip the Skylab 2 rescus mission. I don't recall where I read that..

      There was ground based IR photography of Columbia's last re-entry which was released in a very blocky, pixelated form showing that the shuttle was damaged and no longer symmetrical. The original imagery was no doubt better, but not de-classfiable.

        Into The Black indeed. Thanks Gryff

    No need for the tinfoil hats

    Probably testing the Raven system which was installed on the ISS. One of the objectives of Raven is to provide a testbed for satellite servicing:

    Why does it have to be that the spy satellite was manoeuvred to observe the ISS?

    Perhaps the spy satellite was manoeuvred so it could be observed from the ISS. American astronaut checking something post deployment.

    1. james 68

      Probably because the non-Americans aboard also have the capability to look out the windows, including any nefarious cosmonauts. None of whom can I imagine the NRO would want to get a look at one of their spy sats and all of whom have binoculars and DSLR cameras.

      Why?

      Maybe just a bit of "waving the flag" and letting a certain country know that we are watching? I just somehow don't think this was a fluke of orbits but then again, I own a tinfoil hat for those "just in case" moments.

    NRO

    -- Considering some of the amazing amateur photography that has come down from ISS on some of the staffer's DSLRs, I'm wondering if the folks at the NRO just decided that it was time to show those boys and girls what *REAL* photography around the ISS would look like.

    Kudo's to the ISS staffer's that have contributed to irritating the NRO into taking some amazing snaps. Now to get the NRO to show off!

    Isn't there another Space Station which the US might be interested in observing? Rehearsal?
