  Leonardo carries 16 'racks' of equipment, including the Human Research Facility Rack (Rack 13) which will allow the astronauts to do extensive medical experiments, the CHeCS Rack (28), the DDCU-1 and DDCU-2 racks (7 and 9), the Avionics-3 (Rack 6), and the MSS Avionics/Lab (Rack 11) and Avionics/Cupola (Rack 12) racks for a total of 7 equipment racks to be installed on Destiny. Three Resupply Stowage Racks (50, 51, 52) and four Resupply Stowage Platforms (180, 181, 182 and 188) will remain installed on Leonardo, with their equipment bags being individually transferred to the Station. System Racks 2, 3, 4, 5 and 8 are already on Destiny together with stowage racks 110 through 117. Each rack has a mass of around 150-300 kg.
• Discovery was launched on mission ISS-07-5A.1( MPLM "Leonardo") on Mar 8, 2001 at 11:42:09 UTC. At 11:50 UTC the main engines cut off and the external tank separated; orbiter and external tank were at this point in a 60 x 222 km x 51.6 deg orbit. The orbiter fired its OMS engines at 12:21 UTC to raise the orbit to 185 x 219 km, while ET-107 fell back towards the Pacific. Launch mass of Discovery was probably around 114000 kg.
• Discovery docked with the PMA-2 port on the Station at 06:39 UTC on Mar 10, Usachyov became a member of the ISS crew at 10:34 UTC.
• On Mar 11 Jim Voss and Susan Helms made a spacewalk from Discovery's airlock. A PAD device used to attach equipment to the RMS arm floated free and Voss retrieved a spare one from Unity, putting the walk behind schedule. The PAD has been cataloged by Space Command as satellite 26723, international designation 2001-010B.
  The astronauts installed the Lab Cradle Assembly and the Rigid Umbilical on Destiny and disconnected the umbilicals connecting the PMA-3 docking port to Unity. The astronauts then spent two-and-a-half hours back in the depressurized airlock in case their help was needed during the move of PMA-3. Thomas used the RMS arm to unberth PMA-3 from the nadir port on Unity and relocated it to the port port location, freeing up the nadir for the MPLM. The airlock was depressurized at 05:08 UTC and repressurized at 14:08 UTC. Duration was 9h00m (depress/repress), about 6h16m (ingress/egress), 8h54m (hatch open/close), and 8h56m (NASA rule).
• The Leonardo module was unberthed from the payload bay at 04:10 UTC on Mar 12 and berthed at Unity's nadir port at 06:06 UTC.
• Mar 13 saw the second spacewalk, by Andy Thomas and Paul Richards. The airlock was depressurized at 05:18 UTC and the hatch opened at 05:20 UTC. The astronauts took the External Stowage Platform from the ICC carrier to the port side of the Destiny module, and then installed the spare Pump Flow Control System on it. The ESP is used to store on-orbit-spare equipment. Next they hooked up cables on the robot arm's umbilical, and travelled up to the top of the P6 tower to fix a solar array latch - it just needed a good thump - and inspect the FPP experiment. The astronauts returned to the airlock at 11:32 UTC and began repressurizing at 11:44 UTC. Duration was 6h26m (depress/repress), 5h58m (egress/ingress), 6h 13m (hatch open/close), or 6h21m (NASA rules).>
• A minute into airlock repressurization, Shannon Lucid in Houston called up to tell the crew to halt the repress. At 11:49 the airlock began depressurizing again and at 11:55 it was again at zero. A detailed test objective, DTO 257, was testing the effects of firing Shuttle RCS jets while docked to the ISS, and controllers wanted data with the airlock at vacuum, since that changes the dynamics. The airlock was finally repressurized again at 12:09 UTC.
  NASA did not count the new depressurization as an EVA. The hatch remained closed and the astronauts remained inside the airlock.
• Leonardo was removed from Unity at 10:42 UTC on Mar 1 and reberthed around 12:04 UTC. At 02:32 UTC on Mar 19 command of ISS was transferred to Expedition 2 and the hatches were closed. Discovery undocked at 04:32 UTC and flew once around the station before departing at 05:48 UTC. ISS mass after undocking was 115527 kg. The OMS engines fired for the deorbit burn at 06:25 UTC on Mar 21, and Discovery touched down on runway 15 at Kennedy Space Center at 07:31 UTC.
• Mission summary: Docking on ISS; Usachyov, Voss und Helms as "Expedition-2" new resident crew of the ISS; Expedition-1-Crew (Shepherd, Gidzenko and Krikalev) returned to Earth with STS-102; EVA by Helms and Voss on 11.03.2001 (8h 56m - new U.S.- spacewalk-record), Richards and Thomas on (12.03.2001 (6h 21m); Italian-built Multi-Purpose Logistics Module "Leonardo" was attached to the ISS; EVA of Voss and Usachyov from the ISS at 08.06.2001 (19 minutes) to install a docking cone to prepare for the arrival of the Russian docking compartment.
