Expedition 1

This section of the diary covers the period between 2000 October and 2001 March. Bill Shepherd, Yuri Gidzenko and Sergei Krikalev go aboard the International Space Station to become its first long-stay crew while Shuttle visits add further modules to the ISS including the Destiny laboratory.

Date Time (UTC) Event
2000 Oct 6 01:38 Originally planned launch time for Shuttle Discovery to the International Space Station - lift off postponed due to concerns over the separation of the orbiter from the external tank following analysis of the Atlantis /STS-106 lift off - engineers are also concerned about a slow response from a pressure valve in Discovery fuel system
2000 Oct 7 01:16 Planned launch attempt for Space Shuttle Discovery - postponed 24 hrs before lift-off and prior to re-commencing the countdown due to continued concerns over one of Discovery fuel valves
2000 Oct 10 00:04 Second launch attempt for Space Shuttle Discovery - postponed due to high wind conditions at the Kennedy Space Center
2000 Oct 10 23:40 Third launch attempt for Space Shuttle Discovery - postponed due to the presence of an equipment retaining pin lodged in the orbiter support structure and noticed by launch-pad inspection crews - mission managers are concerned about possible damage to the Orbiter should it fall during launch
2000 Oct 11 23:17 Space Shuttle Discovery launched from Launch Complex 39A at the Kennedy Space Center on mission STS-92 into orbit of 160 x 321 kilometres at 51.6 degrees inclination with crew consisting of Col Brian Duffy, USAF (commander), Lt-Col Pamela Ann Melroy, USN (pilot), and mission specialists Koichi Wakata (Japan National Space Development Agency), Leroy Chiao, Peter J K Wisoff, Cdr Michael E Lopez-Alegria, USN, and Col William Surles McArthur Jnr, USA
2000 Oct 12 mission controllers note that Discovery Ku-band antenna has failed, preventing communication via the Tracking and Data Relay Satellite System (TDRSS) - this will limit the transmission of television pictures and high-speed data - the mission itself will be unaffected
2000 Oct 13 Duffy and McArthur use the Remote Manipulator System to conduct a camera survey of the exterior of the ISS
2000 Oct 13 17:45 Discovery docks with the PMA-2 docking adaptor on the Unity Module of the International Space Station while passing over the Ukraine and within range of Russian tracking stations - orbit is 375 x 382 kilometres

2000 Oct 13 21:15 Approximate time - Lopez-Alegria opens the hatch to PMA-2 and Duffy enters the Unity module of the International Space Station, followed by Lopez-Alegria, Chiao and Melroy - they begin to offload supplies for the first resident crew of the station due to arrive 2000 November
2000 Oct 14 Melroy and Wisoff open a hatch inside Unity which leads to the Z-1 truss pressurised compartment and link-up electrical earth (ground) connections between the Truss and Unity
2000 Oct 14 16:50 Approximate time - Wakata and Lopez-Alegria use the Remote Manipulator System (RMS) to lift the Z-1 Truss out of the cargo bay - the operation begins about 2 hours and 15 minutes late due to an electrical short-circuit aboard Discovery and the need to re-route electrical power to several of Discover systems
2000 Oct 14 18:20 The Z-1 Truss is latched in place on Unity upper surface
2000 Oct 14 22:57 The outer hatch between Discovery and Unity is closed - the cabin pressure inside Discovery is then reduced in preparation for a space walk to take place 2000 October 15
2000 Oct 15 14:27 McArthur and Chiao begin a space walk to connect two sets of power cables (a group of six and a group of four) to provide power to heaters and conduits on the Z-1 Truss - the two astronauts also relocate two communication antenna assemblies and install a toolbox on the outside of the Truss - they are assisted by Wakata, who operates the RMS to move them around the shuttle payload bay and outside the ISS
2000 Oct 15 20:55 McArthur and Chiao seal Discovery hatch at the end of the space walk.
2000 Oct 16 14:15 Wisoff and Lopez-Alegria begin a space walk to oversee installation of PMA-3 on the lower face of Unity , they also prepare the Z-1 truss for fitting of solar panels during the next Shuttle visit - they release PMA-3 from it stowage pallet and guide Wakata as he manoeuvres it into position- Melroy then operates the remote control system to tighten the securing bolts - finally, Wisoff and Lopez-Alegria connect cables between the Adaptor and Unity
2000 Oct 16 21:04 Approximate time - Discovery manoeuvring engines are fired eighteen times, for 1.4 seconds each occasion, over a period of thirty minutes in order to raise the ISS orbit to 380 x 381 kilometres
2000 Oct 16 21:22 Wisoff and Lopez-Alegria seal Discovery hatch at the end of the space walk
2000 Oct 17 14:30 McArthur and Chiao begin a space walk to attach power convertors to the Z-1 Truss in preparation for it to have solar arrays attached, to complete the connection of cables between Unity and the Z-1 Truss and between Unity and PMA-3, and to re-route and reconfigure cables between PMA-2 and PMA-3 ready for the next Shuttle mission to use the new docking port - they are assisted by Lopez-Alegria and Wakata, who operate the RMS to move them around the outside of the ISS
2000 Oct 17 21:18 McArthur and Chiao seal Discovery hatch at the end of the space walk.
2000 Oct 17 21:30 Approximate time - for a second time, Discovery manoeuvring engines are fired eighteen times, for 1.4 seconds each occasion, over a period of thirty minutes in order to raise the ISS orbit to 381 x 386 kilometres

2000 Dec 2 The crew of Endeavour transfers a quantity of supplies (including coffee) and some replacement computer hardware to the PMA-3 Adaptor for the ISS crew (the two crews will not meet until all space walks are completed because of the need to maintain a lower air pressure inside Endeavour )
2000 Dec 2 19:59 Endeavour docks with the PMA-3 docking adaptor on the Unity Module of the International Space Station while passing over Kazakhstan - orbit is 374 x 380 kilometres

2000 Dec 11 23:04 Wheel stop - Endeavour mission is completed
2000 Dec 20 15:00 Approximate time - by virtue of its lower orbit, Progress M1-4 has reached a point about 2300 kilometres ahead of the ISS - firings of its manoeuvring engine raise the orbit from 367 x 384 kilometres to 372 x 382 kilometres which begins to reduce the separation distance between the two craft
2000 Dec 23 21:42 ISS passes Progress M1-4 at about 5 kilometres distance and the freighter begins to fall behind the space station in order to set up the right conditions for an approach prior to re-docking

2001 Feb 10 01:00 Approximate time - the Shuttle crew leaves the ISS and the hatches are closed in order that the Orbiter cabin pressure can be lowered from 750 to 500 mm ready for the some of the Shuttle crew to undertake space walks
2001 Feb 10 11:48 A minor adjustment, adding approximately 1 kilometre to the orbital altitude, ensures that the ISS will avoid the possibility of colliding with a piece of space debris which has been detected on a path which might bring it close to the Station

2001 Feb 18 17:53 Planned landing time for Atlantis - the Shuttle is waved-off on this and the next orbit due to high crosswinds on the Kennedy Space Center runway
2001 Feb 19 18:27 Possible landing time for Atlantis but, for a second day, the Shuttle is waved-off on this and the next orbit due to unfavourable weather at the Kennedy Space Center
2001 Feb 19 21:37 The core module of the Mir space station celebrates its fifteenth anniversary in orbit

2001 Mar 8 16:00 Discovery orbit is 233 x 273 kilometres
2001 Mar 10 05:34 Originally planned time for docking of Discovery with the ISS - it is delayed by difficulty with one of the main solar panels which were turned edge-on to Discovery on its approach to minimise contamination from exhaust plumes - it will not latch in place as planned so the panel is rotated slightly in order that an alternative latch can be used

2001 Mar 15 Discovery manoeuvring engines are fired repeatedly over a period of fifty minutes in order to raise the ISS orbit to 372 x 389 kilometres - this re-boost is 24 hours earlier than planned due to a need to move the ISS away from the orbit taken up by a 5 kg foot restraint which floated out of the cargo bay during the space walk 2000 March 11
2001 Mar 18 Compitations show that, through atmospheric drag, Mir's orbit will have reached a low-enough altitude for de-orbiting 2001 Mar 23
2001 Mar 18 10:40 Using the RMS, Thomas detaches Leonardo from Unity - the event has been delayed four hours due to the crew having to check for air leaks around Unity hatch
