Because the object is seen approaching the space shuttle and maneuvers to the right as it close the distance. It's properties are not indicative of the behavior properties of a water droplet in microgravity. And, this wasn't the only time such an object was seen by shuttle astronauts either.
Sorry for the slow response, but I've been busy at work and haven't had a chance to post for a few days.
Is the object approaching from a distance? If so, there should be some evidence in the video. We should expect to see the object initially appear small, since it is a long way away from the camera. We should then see it grow larger and larger until it reaches its final distance. Something similar to this sequence:

But what do we actually see? I grabbed as many distinct frames as possible from the zoomed-in portion of the video here (link) and then adjusted brightness levels in Photoshop to enhance the visibility of the objects. Heres the actual sequence from the objects initial appearance to the point where it first crosses the Earths horizon:

Theres no obvious change in apparent size, but lets take it one step farther. In the following sequence, Ive drawn an oval around the object in the final frame to outline its size. Ive then copied that exact same oval into each of the preceding frames and positioned it over the visible portion of the object. This makes it very clear that the object is not changing size during the sequence. Admittedly, the first frame in the sequence is pretty indistinct, but the brighter area appears to fill at least a significant portion of the oval.

The object DOES, however, noticeably grow in brightness as it moves toward the Earths horizon. As Ive stated before, this is completely consistent with the behavior of a droplet of water refracting more and more of the bright Earth behind it.

COMPARISON OF STS-51A OBJECT AND WATER DROPLET AT DIFFERENT POSITIONS FROM HORIZON

As for the objects motion through the frame, Ive already posted a video to show how camera motion can create large apparent motions in a water droplet stuck to a window (link). Because the droplet is very close to the lens, slight shifts of the camera cause the droplet to appear to move much more than the more distant background. If you watch my video, though, you can see that the background does move slightly in sync with the water droplet.
Now, take a look at the STS-51A video again. Heres a link to a short clip that contains only this small video segment (link). Because this version is so short, its easy to watch over and over to get a feel for the motions. Watch as the UFO appears and moves downward and then to the right. Now take a look at the object in the lower right-hand corner of the screen. This is the end effector of the shuttles RMS arm. Its effectively a fixed part of the background in this short clip, so any motion of this item is due to camera movement. Watch the clip again and notice how it, too, moves down and then to the right in sync with the UFO, but over a smaller distance, just like the background objects in my experiment video.
To make this really easy, heres a quick three-frame animation of the clip showing the movement sequence:

THE MOTIONS OF THE OBJECT THROUGH THE FRAME ARE SYNCHRONIZED WITH KNOWN CAMERA MOVEMENTS. This is, again, perfectly consistent with the expected behavior of a droplet of water on the flight deck window being photographed by a hand-held camera.
The evidence, to me, is overwhelming. The most reasonable explanation for the object seen in the STS-51A video clip is just a droplet of liquid, probably water, on the flight deck window. There is no evidence to support a more exotic explanation in favor of this simple one. The same analysis can be performed on the STS-37 clip with the same result.
Skyeagle, you of course have the right to BELIEVE whatever you'd like about the objects in these two clips, but if you'd like to approach this from a scientific perspective, you really need to show some evidence to support your continued dismissal of my claim. I've given you a lot of material to work with here. If you don't agree with it, please SHOW me why.
P.S. to morrison 1976:
Thanks for the kind words! Hope the animation above helps to show you how the UFO movement syncs up with the camera movement.
