During their mission, the Expedition 1 crew activated various systems on board the station, unpacked equipment that had been delivered, and hosted three visiting Space Shuttle crews and two unmanned Russian Progress resupply vehicles.

The three visiting Space Shuttles brought equipment, supplies, and key components of the space station. The first of these, STS-97

Some of these flights delivered large modules, such as the pressurized Unity and Zvezda modules, and the first piece of the Integrated Truss Structure

. The manned flights were used for partial assembly of the ISS, as well as to start unpacking the supplies and equipment that we being delivered. Prior to Expedition 1, Krikalev expected the ISS to be very similar to his experience on Mir ten years previous, due to the physical similarities of the stations' components.

The launch of the Expedition 1 crew occurred a week before the United States presidential election

After 33 orbits of the Earth, and a series of rendezvous maneuvers performed by Gidzenko, they docked the Soyuz capsule to the aft port of the Zvezda Service Module on 2 November 2000, at 09:21 UTC. Ninety minutes after docking, Shepherd opened the hatch to Zvezda and the crew members entered the complex.

Alpha

At the end of the first day on the station, Shepherd requested the use of the radio call sign "Alpha", which he and Krikalev preferred it to the more cumbersome "International Space Station". The name "Alpha" had previously been used for the station in the early 90's, and following the request, its use was authorized for the whole of Expedition 1. Shepherd had been advocating the use of a new name to project managers for some time. Referencing a naval tradition

 at the time, disapproved of the name "Alpha"; he felt that Mir was the first space station, and so he would have preferred the names "Beta" or "Mir 2" for the ISS.

First month

In their first weeks on board, the Expedition 1 crew members activated critical life support systems and computer control, as well as unpacked supplies left behind for them by previous supply missions. At this time the station did not have enough electricity to heat all three pressurized modules, so Unity was left unused and unheated. Unity had been used for the past two years to allow U.S. flight controllers to command ISS systems and read station system data.

 docking system. Although manual dockings are routine, they have caused some concern among flight controllers since an attempt in 1997 which resulted in the spacecraft colliding with Mir, causing significant damage.

The astronauts had a heavy workload in the first month, as Shepherd told reporters in a space-to-ground interview: "To me, the biggest challenge is trying to pack 30 hours into an 18-hour work day." Some of the early tasks took longer than scheduled. For example, the activation of a food warmer in Zvezda's galley was scheduled for 30 minutes, but it took the astronauts a day and a half to turn it on.

On 8 December, the hatch between the two was opened and the two crews greeted each other for the first time. It had remained closed to maintain their respective atmospheric pressures. The Expedition 1 crew took this opportunity to leave the station and tour the inside of the space shuttle, which was thought to be good for their psychological well-being.

This Progress spacecraft remained undocked for the duration of STS-97, parked in orbit about a mile away from the station. It docked manually again with the station on December 26 by Gidzenko, after Endeavour left. The automatic docking system for this Progress spacecraft had failed on the first docking in November. The crew spent much of the following week unloading the Progress spacecraft.

Christmas and New Years

On Christmas Day, the Expedition 1 crew were given the day off work. They opened presents delivered by Endeavour and the Progress supply ship. They also each took turns speaking to their families. In the following days they did several video downlinks, some with Russian TV stations. The crew had a quiet New Years. Citing a Naval tradition, for the New Year's entry of the station's log, Shepherd provided a poem on behalf of the crew.

 coolant leak created a contamination scare, which happened when Curbean was hooking up coolant lines to Destiny. The other two spacewalks went ahead without any problems. While the Shuttle was docked, the control of the station's orientation was switched from propellants to electrically powered gyroscopes, which had been installed in September 2000. The gyroscopes had not been used earlier due to the lack of key navigational electronics.

By the end of STS-98, the crew of Expedition 1 had been on the station for over three months, and Shepherd stated that he was "ready to come home". NASA used several techniques to prevent the three crew members from suffering the effects of the "three-month wall" psychological barrier, which had caused depression in previous astronauts. For example they allowed more time for the crew to speak to their families via videophone, and they also encouraged them to watch movies and listen to music they like.

Daily activities

In a typical day, each crew member divided his time between physical exercise, station assembly and maintenance, experiments, communications with ground personnel, personal time, and bio-needs activities (such as rest and eating). The crew's daily schedule usually operated on UTC; for example, a typical morning had been scheduled to begin with an electronic wake-up tone at about 05:00 UTC. But during the expedition, a more typical wake-up time was actually between 06:00 and 07:00 UTC. The crew's sleep habits were sometimes shifted to accommodate the schedules of visiting shuttles or resupply vehicles.

Following the wake-up call, the crew was given some time to clean up, have breakfast, and read e-mail which had been uplinked to them from flight controllers. Their work day included a lunch break at midday (UTC), and ended with a mid-afternoon planning session with flight controllers, regarding the next day's activities. Most days ended with some entertainment, with the crew watching all or part of a movie; this was thought to be good for crew bonding as well as their psychological well-being. After watching 2010, the sequel to 2001: A Space Odyssey (film)

, Shepherd commented, "[There is] something strange about watching a movie about a space expedition when you're actually on a space expedition".

An important part of the crew's schedule was regular exercise. They had three pieces of equipment for this: a stationary bicycle, a treadmill (TVIS

), and a resistance device (IRED) for weight-lifting. The bicycle malfunctioned in mid-December 2000, and wasn't fixed until March. The treadmill, which used bungee cord

s to keep the crew member in place, was designed to reduce the vibrations caused by running. A normal treadmill would have produced enough vibrations to shake the station, and potentially affect the sensitive science experiments on board. The treadmill malfunctioned near the end of February, but some in-flight maintenance fixed the problem within a week.

Ground communications

Until the Unity module was available for use a month into the mission, the astronauts used the Russian VHF

 communications gear (also called the "Regul radio link") in Zvezda and the Zarya module to communicate with the Russian Mission Control Center (known as "TsUP") in Korolev, outside Moscow. The Russian techonology didn't have the use of satellites, so they were restricted to ground passes (called a "comm pass") which lasted for only 10–20 minutes.

. The contact had been planned for 19 December 2000, but due to technical problems, it was delayed to 21 December 2000. Due to the speed of the space station, the window of radio contact only lasted for 5–10 minutes, which was usually enough for 10 to 20 questions.

Science activities

Unlike subsequent expeditions, the crew of Expedition 1 had a somewhat modest amount of science experiments to conduct, due to the priority placed on station construction. The plasma crystal experiment, known as PKE-Nefedov, was one of the first natural science
