There are several threads with amature and professional concepts for deorbiting defunct satellites and space debris.
Can we keep this thread on this and other potential collisions and leave those discussions in those threads?


Edit: From Spaceflight101:

The publicly available SOCRATES conjunction assessment tool processes orbital data from all non-classified objects and shows a conjunction between the Transit 9 satellite and a piece of NOAA-16 debris at 21:53:54 UTC and analysis of non-public data shows possible candidate encounters between the DMSP F9 & OPS 3367A satellites and a potential head-on collision of DMSP F15 & Meteor 1-26 over Antarctica.

DMSP F15 and Meteor 1-26 appear to the the prime candidates for the encounter.

The 1,220-Kilogram DMSP F15 was launched in 1999 atop a Titan II rocket to join the Defense Meteorological Satellite Program as the first Block 5D3 satellite. Meteor 1-26 is a Soviet-era weather satellite orbited in 1976 with a launch mass around 2.2 metric tons.

Based on available orbital data, the two satellites will have a very close encounter at 21:53 UTC on Saturday, some 870 Kilometers above Antarctica. If a collision occurs between these two, it will be mostly head-on – creating the highest possible relative velocity between the two objects.

edit 2:  DMSP-15 is one of that series that has NOT had a battery explosion. 
People have discussed deorbiting DMSP satellites.  We were told that the Air Force has no interest in or budget for doing that.

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

Stay on topic for this particular collision alert. A mod report suggested a lock, but there may be more to this... if additional data comes out that is specific to this, great.

General strategies belong elsewhere.

thanks
