Here's one to keep an eye on. Bigelow Aerospace's experimental inflatable orbiter has captured an anomalous light source on it's cameras. This one could get interesting, since NASA is not in the mix with their standard dismissal stories ready to slap one in place.
They aren't making any claims so far one way or the other as to what the phenomenon is, but have it open for analysis and discussion at this point.
