1100 GMT (6:00 a.m. EST)
The Orbiter Boom Sensor System has been berthed in the payload bay, its job complete for the mission. Analysts on the ground will be examining all of the imagery gathered and should have the heat shield cleared of any concern by Suday morning.
0932 GMT (4:32 a.m. EST)
The surveys are now finished. They were scheduled to put the inspection boom in its cradle in the payload bay after waking up Saturday afternoon. But Robinson says the crew will do it now instead.
0850 GMT (3:50 a.m. EST)
With Endeavour safely away from the International Space Station, flight controllers are looking ahead to the crew's planned landing Sunday night, assessing threatening weather in Florida and California and evaluating a variety of landing options.

Read our full story.
0810 GMT (3:10 a.m. EST)
Observations of the port wing are now underway aboard shuttle Endeavour by commander George Zamka, pilot Terry Virts and flight engineer Steve Robinson. This is the third and final part of the inspections for today.
0745 GMT (2:45 a.m. EST)
Commander George Zamka, pilot Terry Virts and mission specialist Kay Hire are performing this inspection of Endeavour's reinforced carbon-carbon nose cap.
0725 GMT (2:25 a.m. EST)
The astronauts are using the Orbiter Boom Sensor System on the end of the shuttle's robot arm for a series of heat shield inspections. The inspections are similar to the ones performed the day after launch. Today's survey results will be compared with the earlier data to ensure the orbiter's wing leading edge panels and nose cap are free of any space debris impacts that could have happened during the mission.
0700 GMT (2:00 a.m. EST)
The right wing has been scanned using the laser and camera package of the Orbiter Boom Sensor System. The crew is swinging the boom in position to inspect Endeavour's nose cap next.
0612 GMT (1:12 a.m. EST)
Endeavour is about 19 miles from the station and separating at about 10 miles per orbit now, Mission Control says.
0605 GMT (1:05 a.m. EST)
The starboard wing surveys are getting started under the control of mission specialists Kay Hire, Steve Robinson and Nick Patrick.
0512 GMT (12:12 a.m. EST)
The crew has the inspection boom in motion for tonight's heat shield inspections.

Before getting started, the astronauts helped collect some additional data for engineers on the ground looking at Endeavour's fuel cell No. 2. That electricity-producing device failed an internal self test earlier tonight. But Mission Control believes the fuel cell is fine.
0231 GMT (9:31 p.m. EST Fri.)
The shuttle is quickly departing the vicinity of the space station following separation burn No. 2 producing a 3 feet per second change in velocity.

The astronauts will spend the late-night hours using the Orbiter Boom Sensor System to inspect the shuttle's wing leading edge panels and nose cap to look for any space debris or micrometeoroid damage that could have occurred during the mission. Standard day-before-landing tests of Endeavour's flight controls and thrusters, along with packing up the cabin for entry will fill the crew's Saturday night in orbit.

Landing at the Kennedy Space Center to conclude this spaceflight is scheduled for 10:16 p.m. EST on Sunday.

The early weather forecast for the Kennedy Space Center has a chance of showers around the landing site that would prohibit the shuttle's return.

The outlook for the Florida spaceport includes scattered clouds at 4,000 and 12,000 feet, a broken deck at 25,000 feet, seven miles of visibility, southerly winds from 160 degrees of 10 peaking to 14 knots and that "chance" of showers within 30 miles.

The backup site at Edwards Air Force Base in California, which will be called up for support on Sunday, has rain showers and a low-cloud ceiling in its gloomy forecast.

The outlook for the military base in the high desert includes showers within 30 miles, broken decks of clouds at 3,000 and 6,000 feet, a overcast skies at 10,000 feet, seven miles of visibility, southwesterly winds from 220 degrees of 8 peaking to 12 knots.

If the landing is delayed to Monday night, KSC's forecast worsens and Edwards improves slightly but remains "no go."
0230 GMT (9:30 p.m. EST Fri.)
Over 7,000 feet away now.
0225 GMT (9:24 p.m. EST Fri.)
Now 5,300 feet between the two spacecraft, separating at 5.36 feet per second.
0215 GMT (9:15 p.m. EST Fri.)
Endeavour is climbing high above and behind the station. Now 2,500 feet away, separating at 4.16 feet per second.
0210 GMT (9:10 p.m. EST Fri.)
The shuttle is 1,400 feet from the station and about 20 minutes away from the next engine burn.
0202 GMT (9:02 p.m. EST Fri.)
The shuttle just performed the first of two separation engine firings. This brief burn changed Endeavour's speed by about 1.5 feet per second.
0201 GMT (9:01 p.m. EST Fri.)
Endeavour is back out in front of the International Space Station to complete its full victory lap.
0150 GMT (8:50 p.m. EST Fri.)
"You guys are looking absolutely marvelous down there," commander Jeff Williams says from the space station to the Endeavour crew.
0149 GMT (8:49 p.m. EST Fri.)
The shuttle is 655 feet beneath the station now, continuing its circle around the complex.
0139 GMT (8:39 p.m. EST Fri.)
The shuttle is nearing a point directly behind the station in terms of the direction of travel of the two spacecraft around the Earth, which is known as the -V bar.
0137 GMT (8:37 p.m. EST Fri.)
Endeavour is descending in its loop around the station. Now about 700 feet away.
0135 GMT (8:35 p.m. EST Fri.)
The shuttle Endeavour undocked from the International Space Station Friday, leaving a new habitation module and observation deck behind that virtually complete the U.S. segment of the lab complex after more than 11 years of construction.

Read our full story.
0131 GMT (8:31 p.m. EST Fri.)
Distance between the two craft has grown to 655 feet.
0126 GMT (8:26 p.m. EST Fri.)
Endeavour is reaching a point about 600 feet directly above the space station.

The flyaround started with the shuttle in front of the station. It takes Endeavour to a point directly above the complex, then behind it, looping below and back out in front. After climbing above the station for a second time, the final separation engine firing will be performed. This burn will send Endeavour away from the vicinity of the station.
0122 GMT (8:22 p.m. EST Fri.)
The flyaround is running ahead of the expected timeline.
0120 GMT (8:20 p.m. EST Fri.)
Endeavour is about the 460 feet from the station.
0116 GMT (8:16 p.m. EST Fri.)
Pilot Terry Virts has begun flying Endeavour in a one-lap flyaround of the station.
0114 GMT (8:14 p.m. EST Fri.)
As the sun rises, a shadow of Endeavour is being cast on the giant solar wings of the space station. A spectacular sight!
0114 GMT (8:14 p.m. EST Fri.)
The spacecraft are passing into an orbital sunrise over Russia.
0112 GMT (8:12 p.m. EST Fri.)
The shuttle is headed to a point more than 500 feet away where it will fire thrusters to begin an arc above the station for today's flyaround.
0110 GMT (8:10 p.m. EST Fri.)
Now 262 feet of separation.
0108 GMT (8:08 p.m. EST Fri.)
Endeavour is 210 feet from the station, continuing to separate at 0.34 feet per second.
0106 GMT (8:06 p.m. EST Fri.)
About 170 feet separate the two craft.
0105 GMT (8:05 p.m. EST Fri.)
The two spacecraft are passing over Europe now.
0103 GMT (8:03 p.m. EST Fri.)
Now 130 feet of separation with Endeavour moving away at 0.3 feet per second.
0102 GMT (8:02 p.m. EST Fri.)
The International Space Station, more than a decade into the assembly process, now has a mass of 799,045 pounds. Following's Endeavour's construction flight that added the Tranquility module, the outpost is 90 percent complete by mass and 98 percent complete by internal volume.
0057 GMT (7:57 p.m. EST Fri.)
Endeavour is 20 feet from the station as it slowly backs away.
0056 GMT (7:56 p.m. EST Fri.)
"United States space shuttle departing," International Space Station commander Jeff Williams says as he rings the station's bell.
0055 GMT (7:55 p.m. EST Fri.)
The undocking occurred on time as the two spacecraft flew 208 miles over the Atlantic Ocean.
0054 GMT (7:54 p.m. EST Fri.)
UNDOCKING! Endeavour and the International Space Station are parting company after 9 days, 19 hours and 48 minutes of being linked together high above Earth. The successful visit by the space shuttle delivered and activated Tranquility, a module to house life-supporting equipment and exercise gear for the astronauts, and raised the curtains on the cupola, a panoramic bay window on the world.

Endeavour is due home at the Kennedy Space Center on Sunday night, weather permitting.
0053 GMT (7:53 p.m. EST Fri.)
Hooks and latches are driving open.
0049 GMT (7:49 p.m. EST Fri.)
Five minutes from undocking. The steering jets on Endeavour are inhibited for the period of physical undocking from the station. The separation occurs when large springs push the two craft apart. Once the shuttle is a couple feet away from the station and the docking devices are clear of one another, pilot Terry Virts will fire Endeavour's thrusters to continue the movement away.
0040 GMT (7:40 p.m. EST Fri.)
The spacecraft have passed into an orbital sunset. The undocking will occur in darkness but the later flyaround of the station by Endeavour will take place in daylight.
0037 GMT (7:37 p.m. EST Fri.)
Both the shuttle and station flight control teams report all systems are ready for the undocking at 7:54 p.m. EST. Endeavour's guidance system was aligned this afternoon, the station's giant solar arrays have been positioned to protect them from shuttle thruster plumes and the entire shuttle/station complex was reoriented to the proper attitude for undocking.
0010 GMT (7:10 p.m. EST Fri.)
The docking mechanism in Endeavour's payload bay is being powered up.
The latest version of the NASA Television schedule (Rev. M) can be downloaded here.
2350 GMT (6:50 p.m. EST)
Throughout the time Endeavour has been docked to the space station, the combined stack flew in an orientation with the Russian segment leading the way. This was meant to keep Endeavour's heat shield out of the direction of travel. But as undocking approaches, the stack is being turned 180 degrees to enable Endeavour to separate and fly out in front of the station, reversing its path to docking nearly 10 days ago.
2320 GMT (6:20 p.m. EST)
The Endeavour astronauts are prepping the shuttle for undocking and separation from the International Space Station this evening, leaving the lab complex more than 98 percent complete after the delivery of a new habitation module and multi-window cupola.

Read our full story.
2016 GMT (3:16 p.m. EST)
Undocking day has begun for the space shuttle Endeavour astronauts following the 3:15 p.m. EST wakeup call from Mission Control. The orbiter will separate from the International Space Station at 7:54 p.m. EST, then begin a one-lap flyaround of the outpost.

Read our full story.
0806 GMT (3:06 a.m. EST)
The altitude reboost has been successfully completed. The station-shuttle complex has been nudged into a slightly higher orbit of 219 by 208 statute miles.
0732 GMT (2:32 a.m. EST)
A reboost of the space station's orbit using Endeavour's thrusters has begun. This operation will last 33 minutes.
0645 GMT (1:45 a.m. EST)
And now the space station's Oxygen Generation System rack is being pushed from the Destiny laboratory to the Tranquility module for installation onto the sidewall slot.

This relocation, along with the others performed tonight and earlier in the mission, clears the laboratory of these large racks and makes room for science work. Tranquility is the new utility room to house life-support and exercise equipment.
0555 GMT (12:55 a.m. EST)
After breaking for lunch, the astronauts are back at work hooking up the umbilicals for the water and urine processor assembly racks.
0421 GMT (11:21 p.m. EST Wed.)
The space station's U.S.-built toilet has been installed into the sidewall of Tranquility.
0409 GMT (11:09 p.m. EST Wed.)
Both racks for the Water Recovery System have been installed into the floor of Tranquility, Mission Control says. Station commander Jeff Williams is preparing to move the Waste and Hygiene Compartment, which is the rack containing the toilet.
0332 GMT (10:32 p.m. EST Wed.)
The first Water Recovery System rack is en route from Destiny to Tranquility right now, as the astronauts push the refrigerator-sized structure from its temporary position to its permanent home on the space station. This particular WRS rack is used to recycle urine into drinkable water again.
0055 GMT (7:55 p.m. EST Wed.)
Endeavour astronaut Steve Robinson is working in the floor of the International Space Station's Destiny laboratory to disconnect umbilicals for the Water Recovery System. The two urine and water processor racks will be moved over the Tranquility tonight, along with the toilet and oxygen generator.
Speaking about NASA for the first time since announcing sweeping changes to the space program, President Obama said his commitment to NASA is "unwavering" and promoted the agency's new focus on research and development.

2117 GMT (4:17 p.m. EST)
It's wakeup time for the space shuttle Endeavour astronauts to begin Flight Day 11 -- their bonus day in orbit that was added when the mission got extended. This day will be devoted to transferring the life-support systems racks into the new Tranquility module from other parts of the space station.

They'll also receive a call from President Obama at 5:15 p.m. EST. Here is NASA's press release announcing the event:

President Obama, congressional leaders and middle school students will speak with the astronaut crews of the International Space Station and the space shuttle Endeavour Wednesday at 5:15 p.m. EST to congratulate them on their successful ongoing mission. The call will take place from the Roosevelt Room of the White House.

Media attendance will be limited to a White House pool spray, but the White House and NASA Television will stream live video of the event online. The online video also can be embedded into sites using the embed code accessible by clicking "share" next to the event video at: http://www.whitehouse.gov/live

Endeavour's crew members are Commander George Zamka, Pilot Terry Virts and Mission Specialists Kathryn Hire, Stephen Robinson, Nicholas Patrick and Robert Behnken. The Expedition 22 space station crew members are Commander Jeff Williams and Flight Engineers Oleg Kotov, Maxim Suraev, T.J. Creamer, and Soichi Noguchi.

Endeavour and its crew launched Feb. 8 on the STS-130 mission to the space station. During the mission, astronauts installed the Tranquility node and a cupola with seven windows that provide a panoramic view of Earth, celestial objects and visiting spacecraft. Tranquility and its cupola are the final major U.S. portions of the station.

Joining the president are 12 students from Birney Middle School of Detroit, Elkhorn Middle School of Omaha, Neb., St. Thomas the Apostle of Miami and Davidson IB Middle School of Davidson, N.C. These students are in Washington as leaders of four of 39 teams participating in the "Future City" engineering competition hosted by National Engineers Week.

Building on the president's "Educate to Innovate" campaign and his emphasis on inspiring young adults to pursue excellence in science, technology, engineering and math, the students are all leaders of teams that are finalists. The competition included 34,000 seventh and eighth graders from across the nation who produced innovative ideas and designs for a city of tomorrow.
