. These tests showed that the panels had not worsened over the course of the past two flights of Discovery, and the orbiter project engineers concluded in August that Discovery was safe to launch as is. Had a decision been made to repair the panels, the orbiter would have been rolled back to the VAB, delaying the launch.

On 16 October 2007, NASA Managers completed the Flight Readiness Review, and held a press conference to announce the mission plan. The issue of the RCC panels raised by NESC was found to be of little immediate concern, because the NESC took pre-flight thermography data from Endeavour and compared it with Discovery, but there was no commonality in flight history between the two vehicles. The research showed no significant difference between the panels prior to STS-114, and the panels today, which indicates the coating has not worsened during the previous flights, adding confidence that Discovery's RCC panels have had no deterioration in the flights since. NASA announced on the main shuttle page that "The Space Shuttle Program has determined that Discovery's astronauts can safely carry out their mission without having to replace the panels."

23 October (Flight Day 1, Launch)

Discovery launched on time at 11:38 EDT (15:38 UTC). In the countdown's final minutes, a piece of ice, measuring 4 inches (10.2 cm) x 0.5 inches (1.3 cm) was seen on the hydrogen umbilical between the orbiter and the external tank. The inspection team was called back to the pad (a contingency that has been practiced, and used before), to get a closer look at the ice build-up. NASA flight controllers deemed it too small to pose a threat to the thermal protection system. The ice was attached to a Kapton

, would likely come off at main engine ignition. Had it been on other metal surfaces around the liner, this may have posed a threat of staying on and breaking off at a critical part of launch. Despite these issues, the launch continued as planned. The forecast for launch initially was a 60% chance of weather prohibiting launch, and although the launch team weather officers were tracking an incoming storm, the weather remained favorable for launch. Present for the launch was George Lucas

s (EMUs, or spacesuits) that will be used on the EVAs, and doing some preliminary work to get ready for docking with the International Space Station on Thursday. Deputy Shuttle Program Manager and Mission Management Team (MMT) chairman John Shannon noted during the status briefing that the preliminary data the team had reviewed showed no items of concern, and the ascent imagery showed no significant losses prior to SRB separation. Shannon said there were several items the team was waiting for higher resolution imagery to assess, including a possible protruding gap filler, and some external tank foam losses, but there was nothing to indicate any problems. Shannon also noted that a vapor trail was seen coming off the external tank for several seconds during launch, but noted that this was a condition seen during both STS-114, and STS-121

, and was found to be condensate coming off the back side of the tank. Due to the temperature and humidity, combined with the angle of the sun for Discovery's launch, the plume appeared more dramatic in some of the imagery. This was considered an "expected condition", and Shannon confirmed it was of no concern.

25 October (Flight day 3)

The crew of STS-120 worked through the rendezvous procedures in the morning leading to the rendezvous pitch maneuver

, with Anderson's seat liner taken into Discovery. This marked the official end of Expedition 16 for Anderson, and the start of Tani's increment. Just before the two crews signed off to sleep, they were informed that after preliminary review of the RPM photography, focused inspection of the orbiter's heat shield would not be required. During the MMT briefing, Shannon confirmed that initial evaluation of the available data showed Discovery to be a "pretty clean vehicle". He also confirmed they were not working any issues or items of interest. Shannon said the piece of ice that was looked at prior to launch dislodged during main engine ignition, and as it fell, the ice appeared to graze the underside of the orbiter at the beginning of ascent, but the area around the impact site was in good condition, and the ice did not appear to have caused any damage. Shannon said the teams would continue to evaluate the imagery and data, but the shuttle was in a good configuration.

26 October (Flight day 4)

The two crews started the day by preparing for the mission's first spacewalk, which began at 10:02 UTC, and ended at 16:16 UTC. Parazynski and Wheelock successfully completed all EVA activities, including preparing Harmony for removal from the payload bay. Wilson, Tani, and Anderson controlled the station's robotic arm, moving Harmony out of the bay and onto the port side of the Unity node
Unity Module
thumb|right|300px|ISS Unity connecting module The Unity connecting module was the first U.S.-built component of the International Space Station....

. At 15:38 UTC, Harmony was officially mated to the space station. The station's new addition adds 2666 cubic feet (75.5 m³) to the station's living volume, an increase of almost 20%, from 15000 ft3 to 17666 ft3.

At the Mission Management Team meeting, managers cleared Discovery's heat shield for reentry, and verified that focused inspection was not required, but noted that late inspection will still be performed on flight day 13 following undocking. John Shannon mentioned that managers have decided to add a task to the second EVA, asking the astronauts to visually inspect the Solar Alpha Rotary Joint (SARJ) on the starboard side, as the joint has registered some vibration for the past month and a half. While the friction is not constant or severe, managers will have Tani remove the insulation covers from the joint to photograph the swing bolts on the joint since Tani would be near the area during the EVA.

27 October (Flight day 5)

The two crews worked to prepare Harmony for entry in the morning, connecting power and data cables, and at 12:24 UTC, the hatch was opened, and the crew was allowed to enter. Whitson, Malenchenko, and Nespoli entered first, wearing masks, and installed a temporary air duct to the node, to allow the air inside to circulate through the station's filters. Until the air is fully exchanged, occupancy of the node is limited to only a few crew members at a time, and they are not to remain inside for extended periods. Some of the work the crew has to do inside the node is to remove approximately 700 screws and bolts that are holding down equipment and panels, placed for security during launch, but not needed in space. After allowing the ventilation system work for several hours, the two crews participated in a press conference with CBS

 from inside Harmony.

28 October (Flight day 6)

The two crews awoke at 05:08 UTC, and began preparing for the second EVA. Parazynski and Tani began the spacewalk at 09:32 UTC, a half hour ahead of the planned timeline. The pair started with the P6 truss, removing the attachments to the Z1 truss, which allowed Wilson and Wheelock to use the station's robotic arm to move the truss to a position where it was "parked" for the night. Joking to Wilson "Don't drop it!", Parazynski then moved on and installed handrails onto Harmony, while Tani went to inspect some items requested by the managers, including handrails on a Crew and Equipment Translation Aid (CETA) cart, that was considered as a possible cause of Rick Mastracchio

's glove tear on STS-118. Tani noted the handrail appeared to be intact, with no obvious sharp edges. Tani then moved on to the Solar Alpha Rotary Joint (SARJ) that has had an intermittent vibration for over a month. After removing the cover from the joint, Tani called down to the team to let them know he saw some metal shavings, and some wear patterns and discoloration on one of the rings inside the joint. "It's like the result that you get with the metal, iron filings and you put a magnet under it and they stand straight up." Tani collected some of the shavings onto some tape, which returned to Earth with the shuttle for further analysis. Managers decided to add a task to Tuesday's EVA, having Parazynski inspect the port (left side) SARJ, using photography and video to compare it to the starboard SARJ inspected by Tani.

29 October (Flight day 7)

The two crews used the morning to move the P6 truss from its overnight position on the station's robotic arm, over to the shuttle's robotic arm. The crew then moved the station's arm along the mobile transporter to an outboard work site that allows attachment of the P6 truss to its new location on the P5 truss on Tuesday. Managers on the ground had Whitson perform an experiment on the shavings Tani collected from the SARJ on Sunday's EVA, putting a magnet under a slip of paper, and testing to see if the shavings collected on the paper, to ascertain if they were metal. The test confirmed the particles collected by Tani were ferrous

. This information allowed the managers on the ground to rule out some possibilities of the origin of the particles, such as the thermal covers, which are made of aluminized mylar.

The Mission Management Team discussed the SARJ issues with the ISS team, and decided to add an extra docked day to the mission, between flight days 11 and 12. The new plan changed the objectives of EVA four from the heat shield repair materials testing, to a more thorough inspection of the starboard SARJ. With the new flight plan, Discovery would undock on 5 November 2007 with a landing on 7 November 2007, at approximately 05:11 EST.

30 October (Flight day 8)

The two crews spent the morning preparing for the mission's third EVA, which began at 08:45 UTC. The EVA completed the installation of the P6 solar arrays onto the P5 truss, and the rest of the EVA activities were accomplished successfully, with the EVA ending at 15:53 UTC. Once the P6 solar array was attached, the process of deploying the arrays began. The first set of arrays, 2B, was successfully deployed with no issues, but during the deployment of the 4B array, the crew halted when they noticed an abnormality. Initial images taken by the crew and station cameras showed what appeared to be a tear in a small portion of the array. During a press briefing, ISS Program Manager Mike Suffredini said the crew took high resolution images of the solar array, and the managers would analyze the images overnight to determine a course of action. Sufredini mentioned that with the array in the 90% unfurled position, it was still generating 97% of the expected power to the station, only slightly less than a fully unfurled array.

31 October (Flight day 9)

The crew began the day working through a variety of tasks, including preparing for the fourth EVA, installing a Zero Gravity Stowage Rack in Harmony, and working with some of the experiments on board. Nespoli and Melroy participated in a Public Affairs event (PAO), and received a call from the President of Italy, Giorgio Napolitano

. The entire crew took part in a second PAO event, fielding calls from news agencies from the United States, Europe, and Russia. Around 15:00 UTC, mission control informed the crew that Thursday's planned EVA would be postponed to either Friday, or perhaps Saturday, to allow for a new EVA plan to be worked out, which would include troubleshooting of the P6 solar arrays.

1 November (Flight day 10)

Shortly after awakening in the morning, the crew was informed that the managers had chosen to take an extra day to evaluate and plan the fourth EVA. Managers initially planned for the EVA to be done on flight day 11, but would use an extra day to conduct further analysis and allow the crew to have extra time to make the tools and equipment needed, and to review and practice the procedures. The crew took some time out to gather in the Harmony module to speak with former President George H. W. Bush

 and his wife, Barbara, who were visiting Johnson Space Center.

The rest of the day was devoted to assembling and configuring the new equipment and tools that would be required for the solar array repair, including a tool termed a "cufflink". The tear in the array is located at one of the hinges, which carries the load of the array, so the cufflink will be a load-bearing strap to relieve the pressure from the snagged area, transferring the load from the hinge, to the cufflink. The cufflink is made up of two wires, with two tabs at the end, that are threaded through existing reinforced aluminum holes in the solar array panels. The EVA plans call for the space station's robotic arm to grapple the shuttle's orbital inspection boom, with an extension on the end, to allow Parazynski to reach the solar array while positioned on a foot restraint at the end of the system. Wheelock will be watching to let the team know the clearances, and to assist Parazynski and the robotics team with positioning. With the changes to the timeline, the crew would be shifting their sleep schedule, to allow for a daylight landing on Wednesday, rather than the early morning landing that was originally planned. The fifth EVA that was planned for the Expedition 16 crew during the mission was delayed, and will be performed by the station crew after the shuttle departs.

2 November (Flight day 11)

The shuttle and station crews spent the day discussing the new EVA plan with managers on the ground, reviewing the procedures, completing the tool configurations, and going over the timeline for the fourth EVA, scheduled for Saturday. The crew also positioned the station's mobile transporter and robotic arm on the end of the truss, to allow the apparatus to reach the solar array. Saturday's EVA would be the first operational use of the Orbiter Boom Sensor System (OBSS) to reach a worksite, although the task was tested and demonstrated during STS-121 to show the boom could provide a stable work platform for EVA activities.

3 November (Flight day 12)

, the station and shuttle crews got to work preparing for the mission's fourth EVA. The spacewalk began at 10:03 UTC. After translating out to the robotic arm, Parazynski attached himself to the adjustable portable foot restraint (APFR), and was taken to the solar array worksite. Working slowly, with direction from Wheelock and the ground team, Parazynski secured the five cufflinks to the array, and then backed away to observe the deploy action. Inside the station, the crew deployed the array a half a "bay" at a time, and the array was fully deployed at 15:23 UTC. After performing additional inspections of both the 2B, and 4B arrays, Parazynski and Wheelock finished the EVA at 17:22 UTC. With the mission's final spacewalk completed, Parazynski has completed seven EVAs, for a total time of 47 hours, 05 minutes, placing him 5th overall for total EVA duration. Wheelock completed three EVAs, for a total time of 20 hours, 41 minutes, and the total EVA time for STS-120 was 27 hours, 14 minutes. During the EVA, a pair of needlenose pliers floated free of the equipment, and was observed floating nearby the window by the crew inside the station. The tool floated clear of the station, and was not a hazard.

4 November (Flight day 13)

The Shuttle and station crews spent the day transferring cargo, and resting in preparation for Monday's departure of Discovery. Nespoli and Melroy spent some time in the morning speaking to the Italian media, and later in the day the crew had some off-duty time. Following the traditional farewell ceremony, the hatches were closed at 20:03 UTC. During the emotional ceremony, Anderson spoke to the ground crew, expressing his gratitude for their support during his 137 days as an Expedition crewmember.

5 November (Flight day 14)

The two crews spent the morning preparing for Discovery's undocking from the International Space Station. At 10:32 UTC, the orbiter successfully backed away from the Pressurized Mating Adapter on the Destiny Laboratory, and pilot Zamka began the fly-around to allow the shuttle crew to photograph the new configuration of the station. After performing the final separation burn, focused inspection began, to scan the wing leading edges and nose cap, the final analysis that allows the ground team to clear the orbiter for re-entry on Wednesday.

6 November (Flight day 15)

The crew of Discovery spent the day preparing Wednesday's landing. In addition to doing final packing and stowing activities, Melroy and Zamka did a check of the orbiter's systems, including the flight control systems, and the reaction control system jets. The crew took some time out in the morning to speak to the media, and then had a deorbit preparation briefing with the ground team. Melroy performed a burn of the orbiter's engines in the afternoon, an orbit adjustment burn done to refine the orbiter's trajectory for the two Wednesday landing opportunities at Kennedy Space Center. NASA managers officially cleared Discoverys heat shield for landing after reviewing the data sent down by the final inspection on Monday.

, as the weather looked favorable for both landing opportunities at Kennedy. The weather forecast at the Shuttle Landing Facility called for good visibility, with mostly sunny skies, although the headwinds would be evaluated, as they had been peaking at 23 knots (45.1 km/h). Due to the sleep shifting done by the crew earlier in the mission to schedule the extra mission days, the landing was done on what is called a "descending" node entry. Unlike ascending node entries, this entry trajectory brought the shuttle diagonally across the United States for the first time since STS-107

, Canada, and angled down towards Florida. Once the orbiter reached Florida, Melroy performed a 195-degree right overhead turn along the heading alignment cone (HAC) in order to line up for a landing on Runway 33. The first landing opportunity began with a deorbit burn at 16:59 UTC and finished with a landing at 13:01 EST. The deorbit burns were done to slow the orbiter's speed and to drop it out of freefall orbit and on target for the designated runway.

Discovery's payload bay doors were closed at 14:13 UTC, and the crew began fluid loading at 16:00 UTC. Fluid loading is a procedure that involves drinking high salt content fluids, which allows the astronauts to adjust to the return to gravity, and reduces the chance of hypotension

 gave the crew the "go" for deorbit burn. The initiation of the burn committed Discovery to landing. The burn was initiated at 16:59 UTC, and was one minute and 53 seconds in duration. The deorbit burn is performed while the orbiter is facing opposite its direction of travel, which allows the engines to act as a braking system, slowing its speed by approximately 215 feet per second (65.5 m/s). After the burn, the remaining propellant in the orbiter's maneuvering thrusters was dumped overboard, at 17:13 UTC. Discovery began to feel the effects of gravity around 400000 feet (121,920 m), as it traveled above the North Pacific Ocean at 17:30 UTC. As the orbiter descended, Melroy initiated a series of "rolls", and roll reversals, which serve to create friction and bleed off additional speed. At 17:40 UTC, Discovery entered the United States, flying over Montana

. At 17:53, the orbiter entered Florida, flying at a speed of 3500 mi/h, and an altitude of 118000 feet (35,966.4 m).

Discovery touched down on runway 33 at 13:01:18 EST, the rear landing gear touching down first, the nose gear touching down at 13:01:32 EDT, and the orbiter came to a complete stop at 13:02:13 EDT. Total mission time was 15 days, 2 hours, 23 minutes, 55 seconds, for a distance of 6.25 million miles in 238 orbits. The completion of STS-120 marks the longest duration mission for Discovery.
