I logged into Space-Track and immediately saw this message:
The 18th Space Control Squadron has confirmed the breakup of SL-12 R/B(AUX MOTOR), #36407. The time of breakup was at approximately 0206z, 22 May 2018. 18 SPCS is tracking approximately 60 associated pieces, all of which have been incorporated into routine conjunction assessment screenings. There is no indication that this breakup was caused by a collision with another object.
This appears to be 2010-007H and part of the Kosmos 2459, 2460, 2461 launch (Glonass).
I'm not used to reading these, and sometimes things are understated. Is this the beginning of the end of the world, or an unremarkable event, or something in between?
18 SPCS tweeted:
18SPCS confirmed breakup of SL-12 R/B (AUX MOTOR) #36407 on 22 May @ 0206z - 60 pieces being tracked - no indication it was caused by collision
According to this 18 SPCS tweet from last year:
JSpOC has transferred routine SSA ops to new unit: 18th Space Control Squadron (18 SPCS). Same SSA support under a different name!
Can I therefore conclude that this is a routine observation and therefore not "the end of the world"?
