Monday, August 8 (Flight Day 14):

01:05
Payload bay door closing

03:20
Capcom Ken Ham has told the Discovery crew that current observations at the landing site are no go due to unstable weather. NASA is waving off the first attempt.

03:25
Weather forecasts will continue to be updated as the morning goes on. Kent Rominger has landed the Shuttle Training Aircraft for refueling, and will then continue weather reconnaissance

03:30
Mission control is giving instructions to Pilot Jim Kelly so he can set up Discovery for the second landing attempt this morning.

03:50
Chief Astronaut Kent Rominger has just taken off in the newly refueled Shuttle Training Aircraft to continue weather reconnaissance.

05:04
Discovery's landing attempts are waved off for today due to unstable weather.

05:15
Aboard Discovery, Commander Eileen Collins and her six crewmates are backing out of deorbit preparations and refocusing their efforts on tomorrow's landing opportunities.

08:19
Crew fire Discovery's engines to adjust the Shuttle's orbit and optimize the landing opportunities for tomorrow.

12:39
Crew go to sleep.

20:39
Crew awake and begin deorbit preparations

Tuesay, August 9 (Flight Day 15):

01:25
Discovery's payload bay doors were closed and sealed for reentry. In anticipation of today's deorbit burn and landing, the orbiter is flying tail first in the direction of travel.

The deorbit burn will begin at 5:37 over the central Indian Ocean and last 2 minutes, 43 seconds. Entry Interface -- when the orbiter first begins to encounter Earth's atmosphere -- will take place over the Islands of French Polynesia in the Pacific Ocean

03:00
The first landing opportunity, at 5:07 this morning at NASA's Kennedy Space Center in Florida, was waved off at about 3 a.m. due to unfavorable weather

04:53
Discovery was just given the all-clear to proceed with a steering check of the orbital maneuvering system, or "gimbal check."

05:02
Continued instability at Kennedy Space Center has led Mission Control to wave off on the second landing opportunity at Kennedy Space Center. Discovery's preparing for a landing at Edwards Air Force Base, Calif. today.

05:09
Capcom Ken Ham is walking Discovery Pilot Jim Kelly through the pre-landing checklist as they prepare for landing at Edwards Air Force Base later this morning. This will be the 50th shuttle landing at Edwards Air Force Base. The deorbit burn will last two minutes, 43 seconds beginning at 7:06 a.m.

06:12
Capcom Ken Ham has informed Commander Eileen Collins that she and her crewmates are to resume fluid loading. Pilot Jim Kelly will pick up with the auxiliary power unit pre-start in about 15 minutes

The deorbit burn, scheduled for 7:06 a.m., will slow the orbiter by just about 186 miles per hour, but that will be enough to put it back on a return trajectory.

06:17
Discovery is beginning its 219th Earth orbit.

06:43
Go for the burn! Capcom Ken Ham has informed Commander Eileen Collins that it's time to come home.

06:56
Now 10 minutes away from the deorbit burn. About 5 minutes prior to the burn, Pilot Jim Kelly will activate one of three auxiliary power units. The remaining two will be activated after the burn, when Discovery has begun its descent. The auxiliary power units power the hydraulic systems that operate the orbiter's aerosurfaces, including the rudder, elevons and landing gear.

07:01
Five minutes until the burn. The first APU is up and running.

07:06
The deorbit burn is underway! High above the western Indian Ocean, Discovery's two orbital maneuvering systems are firing for a 2 minute, 42 second burn that will put it on a trajectory to Edwards Air Force Base.

07:12
Over the next 30 minutes, Discovery will free-fall until it reaches Entry Interface, about 75 miles over the Cook Islands in the South Pacific. Current altitude is 220 statute miles. Post burn procedures are in work.

07:17
Current altitude is 213 statute miles.

07:20
Part of Discovery's reaction control system, the rear steering jets control the orbiter during the early part of descent. As the orbiter transitions from spacecraft to aircraft, those jets are phased out as air pressure builds, and the orbiter's aerosurfaces become active.

07:25
Fifteen minutes until Entry Interface, when Discovery begins to feel the effects of Earth's atmosphere. Discovery's altitude is 175 miles as it continues its descent.

07:28
All three of Discovery's APUs are now up and operating well.

07:30
Ten minutes until Entry Interface.

7:40
Now flying almost 400,000 feet above the Cook Islands in the South Pacific, Discovery is just beginning to encounter the upper reaches of Earth's atmosphere.

07:43
Altitude 56 miles. Discovery is traveling 17,000 miles per hour and is less than 4,000 miles from Edwards Air Force Base.

07:45
Discovery is beginning its first in a series of four banks that will help dissipate its speed as it plunges through the atmosphere. The first roll is to the left at 80 degrees to horizontal. The orbiter's nose is angled upward 40 degrees.

07:46
The rear steering jets have been activated; Discovery is beginning the transition from spacecraft to aircraft as it descends toward landing. The first roll reversal is coming up shortly.

07:50
Discovery is traveling 15,400 miles per hour at 230,000 feet. About 2,000 miles to Edwards.

07:52
In its first of three roll reversals, Discovery is banking back to the right with its wings angled 75 degrees to horizontal. Discovery's current speed is 14,000 miles per hour at an altitude of 217,000 feet.

07:56
Traveling 17 times the speed of sound, Discovery is within 1,000 miles of the runway at Edwards Air Force Base.

07:59
470 miles to touchdown, speed 7,400 miles per hour. Discovery is banking back to the left, the third in a series of four steep rolls to help dissipate speed as it heads for touchdown.

08:02
10 minutes until touchdown. Discovery is in range of ground tracking and using Tactical Air Navigation (TACAN) data. There is one bank remaining in the series of four.

08:04
This will be the 50th landing of a Space Shuttle at Edwards Air Force Base. Eight minutes, 135 miles to touchdown.

08:07
Discovery's wings leveling as it approaches the landing site. Now that the orbiter has gone subsonic, Commander Eileen Collins has assumed control. She'll fly Discovery on a 194-degree right overhead turn to align with runway 22.

08:10
Commander Eileen Collins reports she has the runway in sight! Discovery's altitude is 17,000 feet - 10 miles to touchdown.

Main gear touchdown, nose gear touchdown, chutes deployed... and Discovery is home.

08:12
Touchdown! Discovery is rolling out on runway 22 at Edwards Air Force Base!

08:13
Wheels stop. "Happy to be back," Collins said to Capcom Ken Ham after he offered congratulations.

08:17
A convoy of landing support trucks and equipment are heading out onto runway 22 to begin safing the orbiter and assisting the flight crew. There are 78 Kennedy personnel in that convoy, and a turnaround team of 174 people will fly to Edwards from Kennedy on Wednesday to help prepare Discovery for its ferry flight back to Florida. It takes about 6 days to ready an orbiter for that return flight atop NASA's Shuttle Carrier Aircraft, a modified Boeing 747.

08:21
The ground operations team is continuing through the post-landing safing checklist. The flight crew normally exits the orbiter about 45 minutes or so after touchdown.

08:25
It's still about 40 minutes until sunrise at Edwards Air Force Base, where Discovery is being safed following a successful landing at 8:12 this morning.

08:34
Still inside Discovery, the astronauts have been cleared to take off their bulky, bright orange launch and entry suits.

Official landing time was 08:11:22 EDT / 12:11:22 UT / 13:11:22 BST.
