++Most spacewalks -- five -- during a station assembly mission.
The Endeavour astronauts tied a record jointly held by astronauts on four Hubble Space Telescope servicing missions.
++Longest shuttle stay at the station: 11 days, 20 hours and 36 minutes.
The astronauts delivered the first segment of the Japanese Kibo science research facility, and they assembled a two-armed Canadian robot poised to do maintenance work outside the station.
They knocked off other seemingly mundane-yet-critical construction chores during a mission that raised the bar for future assembly crews.
Said senior NASA manager LeRoy Cain: "It's just been remarkable."
Endeavour and its crew are scheduled to land 33 minutes before sunset Wednesday: 7:04 p.m. EDT.
On the west coast the landing will be at 4:04 PM Wednesday afternoon. Perfect for the kids to watch after school!
