• Endeavour reached an 80 x 317 km orbit at 18:49 UTC; at 19:24 UTC the OMS engines fired to raise perigee. After a series of rendezvous burns, the spaceship docked with the PMA-2 port on the ISS at 13:59 UTC on Apr 21. Launch mass of Endeavour was quoted in the press kit as 103504 kg but it was much larger, probably 115652 kg at ET separation and 114740 kg after the OMS-2 burn.
• Crew of STS-100 are Commander Kent Rominger (NASA), Pilot Jeff Ashby (NASA), and Mission Specialists Chris Hadfield (Canadian Space Agency), John Phillips (NASA), Scott Parazynski (NASA), Umberto Guidoni (ESA), and Yuriy Lonchakov (RAKA).
• Hadfield and Parazynski made a spacewalk on Apr 22 to begin installation of the Canadarm-2. The airlock was depressurized at 11:44 UTC; the hatch was probably opened around the same time. The astronauts went to battery power at 11:45 UTC; the thermal cover was opened at 11:52 UTC as Hadfield emerged to become the first Canadian spacewalker. After a successful spacewalk in which the UHF comm antenna was installed on Destiny and the SSRMS initial setup was completed, they returned to the airlock, closing the hatch at 18:45 UTC and repressurizing 10 min later for a duration of 7h11m (depress/repress), 7h01m (hatch open/close) or 7h10m (NASA rule).
• Unlike the RMS, the SSRMS has a `hand' ("latching end effector" or LEE) at each end and can `walk' along the station from fixture to fixture. The two LEE's are LEE A and LEE B; LEE B was used to connect to the PDGF fixture on Destiny. It was unberthed from the SLP (Spacelab pallet) at 11:14 UTC on Apr 23 and latched on to the PDGF at 14:16 UTC. During the second spacewalk on Apr 24, it started getting power through the PDGF at 14:55 UTC and Susan Helms aboard Destiny started to use the arm's LEE A to lift up the SLP from Destiny. The SLP was unberthed from the Lab Cradle Assembly at 18:25 UTC.
• At 14:58 UTC on Apr 23 the MPLM-2 Raffaello module was unberthed from Endeavour using the Shuttle's RMS and docked to the nadir port on Unit at 16:00 UTC. Over the next few days, the cargo racks on the MPLM were transferred to Destiny. Raffaello was then unberthed from Unity at 20:03 UTC on Apr 27 and reberthed in the rear of Endeavour's bay at 20:59 UTC.
• The second spacewalk began with depressurization of the airlock at around 12:32 UTC on Apr 24. The hatch was probably open around the same time, with the astronauts switching to battery power at 12:34 UTC. They removed a temporary communications antenna from Unity, connected up power to the Canadarm-2, and moved the DCSU switching unit from a sidewall carrier on the port side of Endeavour's cargo bay to the ESP (External Stowage Platform) on Destiny, next to the PFCS (Pump Flow Control System) which was installed on the ESP on the previous mission. The astronauts returned to the airlock at 20:00 UTC, closed the hatch at 20:03 UTC, and repressurized the airlock at 20:14 UTC, for a duration of 7h42m (depress/repress), 7h31m (hatch open/close) or 7h40m (NASA rule).
• Undocking of Endeavour has been delayed due to a series of computer problems on the Station. After three days, failures in the Station's command and control computers are still unresolved and only one of the three computers is up and running. The SLP remains attached to SSRMS LEE A; it is still hoped to return it to the cargo bay before Endeavour leaves.
• Following the two STS-100 spacewalks, and the restarting of the Lab's command and control computers, the Shuttle RMS grappled the Spacelab pallet at 2044 UTC on Apr 28. The SSRMS released it at 2106 UTC, and the RMS berthed the pallet back in the Shuttle cargo bay.
• Endeavour undocked from the Station at 1734 UTC on Apr 29. The weather in Florida was bad at the planned May 1 landing time, so it was decided to bring Endeavour back to California instead. The deorbit burn was at 1502 UTC on May 1, with landing at 1610:42 UTC on runway 22 at Edwards.
• Endeavour returned to KSC aboard one of the two Boeing 747 SCA aircraft on May 9.
