I expanded the scale on the final temperature plot for RAFT, and
it is clear to see the additional data we were getting from all
the great volunteer ground stations. Re-entry was probably at
0347z over the southern Indian Ocean as predicted by Harro
Zimmer. So although we didn't hear RAFT on that last 0300z pass
over the USA, she was there. See the web page.

If RAFT had reset due to high temps during the sun pass 30
minutes earlier, it would have returned to only 1 minute
beacons. But no one reported even hearing any squelch bursts
after that last packet.
Throughout the 5 month 9 day mission, the KPC-3+ TNC command and
control system only had one automatic re-boot. So it worked
very reliably in space. It transmitted probably 1,374,000
packets.
