quick and not so subtle way:
Fly straight in, staying away from the the Steele's-Ship's-Name and the attendant awacs, scan Artemis Station's comms system, then go up the shaft of the installation and scan the weapons system. ((Sensors were bugged for me and took way longer than it should have to find the right angle, but you can just as well ignore it, especially because it is pretty close to the awacs radar range.)) Then play the signal gauge game which takes either forever or almost no time at all, depending on your luck until you find the one which is carrying Clark Henrikson. If getting a fix with the signal gauge and whatnot isn't working out, you can directly scan them all by looping out and scanning from the back of the transport flights forward without being seen, just match speeds and gently slide into range.
Then go up and scan/hack the nearest mjolnir and tell it to shoot the transport. * I can't remember if you can hack right away after scanning weapons or if it is on a timer, I think the latter though.
Hope that helps.
