Interesting to note that the drag multipliers issued by Dave Ransom/Ken
Ernandes for TSS (used in conjuction with vec2tle) have dropped. Last
week they were ~45.0 and in the last couple of days they have dropped to
~1.0 (cf the shuttle which is typically in the range 0.01-1.0). The
tether and satellite body may well have separated as you (Mike) suggest.
The change appears to have occured sometime on or around 2nd March.
