Shuttle Astronauts Disembark Endeavour
26 March 2008 9:54 p.m. EDT

CAPE CANAVERAL, Fla. – The seven astronauts of NASA’s shuttle Endeavour have disembarked their spacecraft after their successful nighttime landing here at the Kennedy Space Center.

The spaceflyers, commanded by veteran shuttle flyer Dominic Gorie, move first into a crew transportation vehicle, where rested up from their 8:39 p.m. EDT (0039 March 27 GMT) landing and 16-day construction flight to the International Space Station. They doffed their orange pressure suits and are on the runway to walk around their spacecraft.

Touchdown! Endeavour Lands Safely in Florida
26 March 2008 8:39 p.m. EDT

Shuttle Endeavour and its crew of seven astronauts has safely landed at Florida's Kennedy Space Center, following a record 16-day mission to the International Space Station (ISS) and the installation of Japan's Kibo logistics module and Canada's Dextre robotics system. After a journey of  6.5 million miles, Endeavour touched down on Runway 15 at the Shuttle Landing Facility at 8:39 p.m. EDT (0039 GMT) – about one hour after local sunset - to complete its 21st space voyage.

Commander Dom Gorie and pilot Greg Johnson guided the Orbiter on its fiery plunge through the atmosphere and hour-long free-fall descent back to Earth, then precisely executed a series of turns and banking maneuvers that bled-off excess speed and slowed the 207,582-pound spaceplane for its powerless landing on the 3-mile long paved runway at the seaside space center. All spacecraft systems performed as expected.

Endeavour touched down on the second of tonight's two landing opportunities – a low deck of moisture-laden clouds over Florida's Space Coast forced NASA to wave-off the first landing attempt, choosing to keep the spacecraft aloft for an additional orbit.

Endeavour's crew includes French astronaut Leopold Eyharts, who returns to earth after a 48-day tour of duty as the ISS Expedition 16 flight engineer. During re-entry and descent, Eyharts was strapped into a special recumbent seat in the orbiter’s middeck, which kept him in a reclined position during the ride home to ease his body’s re-acclimation to gravity.

A convoy of landing support vehicles is now approaching Endeavour and technicians will soon begin to 'safe' the vehicle – purging the spacecraft of its toxic propellants – to be followed by the astronauts' egress and traditional 'walkaround' of the spacecraft.

Endeavour's return marks the 68th space shuttle landing at the Kennedy Space Center and the 22nd nighttime landing in shuttle program history.

Shuttle Endeavour Flying Over Gulf of Mexico
26 March 2008 8:24 p.m. EDT

Shuttle Endeavour is crossing over the Gulf of Mexico, just west of Cuba, as it continues its long, gliding approach to Florida's Kennedy Space Center. Touchdown on Runway 15 at the Shuttle Landing Facility is scheduled for 8:39 p.m. EDT (0039 GMT) – about one hour after local sunset.

Endeavour has just emerged from a lengthy communications blackout; Mission Control confirms that all spacecraft systems are performing as expected.

The Orbiter will soon enter U.S. airspace over the Florida's Gulf Coast, just south of Tampa/St. Petersburg, on its cross-peninsula landing approach. Commander Dominic 'Dom' Gorie and pilot Gregory Johnson are piloting the 207,582-pound spaceplane through a series of turns and banking maneuvers to slow the vehicle and expend excess energy in preparation for its powerless landing, culminating with left overhead turn of 255 degrees to precisely align with Runway 15 – the northwest-to-southeast runway.

Observed weather conditions at the landing site are within acceptable limits for landing, with just a few clouds at 6,000 feet. NASA astronaut Brent Jett, chief of flight crew operations, is flying the Shuttle Training Aircraft on practice approaches to runway 15 and relaying his observations to flight controllers.

Endeavour's touchdown will mark the 68th space shuttle landing at the Kennedy Space Center and the 22nd nighttime landing in shuttle program history.

Endeavour Re-entering Earth's Atmosphere  
26 March 2008 8:07 p.m. EDT

Shuttle Endeavour is now transitioning from spacecraft to aircraft, encountering the upper fringes of Earth's atmosphere - known as 'Entry Interface' - at about 400,000 feet above the southern Pacific Ocean as it begins its fiery descent and a long, gliding approach to the 3-mile long runway at Florida's Kennedy Space Center.

Landing on Runway 15 at the Shuttle Landing Facility is scheduled for 8:39 p.m. EDT (0039 GMT). All spacecraft systems are performing as expected.

With the heat on its Thermal Protection System tiles building to 2,500 degrees F, Endeavour will be flying south to north, across Central America and the Yucatan Peninsula, crossing over the Gulf of Mexico west of Cuba and then descending over Florida's Gulf Coast south of Tampa/St. Petersburg on its final cross-peninsula approach for landing.

Commander Dominic 'Dom' Gorie and pilot Gregory Johnson completed a 2-minute, 45-second firing of Endeavour twin Orbital Maneuvering System engines that began at 7:33 p.m. EDT (2333 GMT) that reduced the shuttle's velocity sufficiently to drop it out of orbit and begin its hour-long free-fall descent back to Earth. Gorie and Johnson will pilot the 207,582-pound spaceplane through a series of turns and banking maneuvers to slow the vehicle for its powerless touchdown at the Kennedy Space Center.

Endeavour will touch down on the second of tonight's two Florida landing opportunities – a low deck of moisture-laden clouds over Florida's Space Coast forced NASA flight controllers to wave-off the first landing opportunity, choosing to keep the spacecraft aloft for an additional orbit.

Prior to the de-orbit burn decision, commander Dom Gorie was asked by Mission Control if he was comfortable flying through a broken deck of clouds between 5,000 and 6,000 feet … Gorie replied that his crew had trained for night landings under similar conditions and gave his concurrence to proceed with tonight's landing attempt.

Weather conditions at the landing site are now forecast to be within acceptable limits for landing.NASA astronaut Brent Jett, chief of flight crew operations, is flying the Shuttle Training Aircraft on practice approaches to runway 15 and relaying his observations to flight controllers.

Endeavour Heading Home to Florida  
26 March 2008 7:36 p.m. EDT

Shuttle Endeavour has ignited its braking rockets to start a fiery plunge through Earth's atmosphere and a long, gliding descent to the Kennedy Space Center's Shuttle Landing Facility where weather conditions are forecast to be acceptable for the spaceplane's return. Endeavour will touch down on the second of tonight's two Florida landing opportunities – a low deck of moisture-laden clouds over Florida's Space Coast forced NASA flight controllers to wave-off the first landing opportunity, choosing to keep the spacecraft aloft for an additional orbit.

Commander Dominic 'Dom' Gorie and pilot Gregory Johnson just completed a 2-minute, 45-second firing of Endeavour's twin Orbital Maneuvering System engines that began at 7:33 p.m. EDT (2333 GMT) to reduce the shuttle's velocity sufficiently to drop it out of orbit and begin an hour-long free-fall descent back to Earth.

Touchdown on Runway 15 at the Shuttle Landing Facility is now scheduled for 8:39 p.m. EDT (0039 GMT).

The de-orbit burn slowed Endeavour's velocity by about 302 feet/second (approx. 206 miles/hour). Endeavour and its crew of seven astronauts will first encounter the upper fringes of the atmosphere at about 400,000 feet above the southern Pacific Ocean, flying north across Central America and the Yucatan Peninsula, crossing over the Gulf of Mexico to the west of Cuba and then descending over Florida's Gulf Coast south of Tampa/St. Petersburg on its final approach for landing.

NASA astronaut Brent Jett, chief of flight crew operations, has been flying approaches to the landing strip in the Shuttle Training Aircraft – a specially modified Gulfstream jet that simulates the shuttle's landing characteristics – closely monitoring that unexpected layer of moisture-laden clouds that are now dissipating as they approach the Kennedy Space Center from the southeast.

Prior to the de-orbit burn decision, commander Dom Gorie was asked by Mission Control if he was comfortable flying through a broken deck of clouds between 5,000 and 6,000 feet … Gorie replied that his crew had trained for night landings under similar conditions and gave his concurrence to proceed with tonight's landing attempt. The Spaceflight Meteorology Group, based at Houston's Johnson Space Center, is now predicting weather conditions to be within limits at the time of landing.

Endeavour 'Go' for Florida Landing  
26 March 2008 7:25 p.m. EDT

Mission managers have cleared shuttle Endeavour for an 8:39 p.m. EDT (0039 GMT) landing at the Kennedy Space Center where weather conditions have improved to permit the spaceplane's return to Earth. Endeavour will touch down on the second of tonight's two Florida landing opportunities – a low deck of moisture-laden clouds over Florida's Space Coast forced NASA flight controllers to wave-off the first landing opportunity, choosing to keep the spacecraft aloft for an additional orbit.

Commander Dominic 'Dom' Gorie and pilot Greg Johnson have been given a 'Go' to initiate the de-orbit burn at 7:33 p.m. EDT (2333 GMT), culminating in a landing on Runway 15 at the Shuttle Landing Facility. Touchdown is scheduled for approximately one hour after local sunset, officially making this a nighttime landing – the 16th in space shuttle history.

Endeavour's Orbital Maneuvering System engines will be fired for 2 minutes and 45 seconds, high above the Indian Ocean, to slow the Orbiter's velocity by about 302 feet/second (approx. 206 miles/hour) to begin its fiery descent through Earth's atmosphere and a long, gliding approach to the 3-mile long runway at the Kennedy Space Center.

Endeavour will first encounter the upper fringes of the atmosphere at about 400,000 feet above the southern Pacific Ocean, flying north across Central America and the Yucatan Peninsula, crossing over the Gulf of Mexico to the west of Cuba and then descending over Florida's Gulf Coast south of Tampa/St. Petersburg on its final approach for landing.

NASA astronaut Brent Jett, chief of flight crew operations, has been flying approaches to the landing strip in the Shuttle Training Aircraft – a specially modified Gulfstream jet that simulates the shuttle's landing characteristics – closely monitoring the unexpected cloud deck and the weather conditions that Endeavour will encounter on its approach and landing.

Mission commander Dom Gorie was asked by Mission Control if he was comfortable flying through a broken deck of clouds between 5,000 and 6,000 feet. Gorie replied that his crew had trained for night landings under similar conditions and gave his concurrence to proceed with tonight's landing attempt.

Endeavour's First Landing Opportunity Waved-Off  
26 March 2008 5:38 p.m. EDT

Florida's dynamic weather will keep shuttle Endeavour in space for at least another orbit. Mission Control has just waved-off this evening's first landing opportunity after a layer of clouds encroached upon the Kennedy Space Center from the southeast.

NASA astronaut Brent Jett, chief of flight operations, has been flying approaches to the landing strip in the Shuttle Training Aircraft - a modified Gulfstream jet that simulates the landing characteristics of the shuttle - and reports a layer of clouds containing moisture that would obscure visibility of the Shuttle Landing Facility with 6/8th's cloud coverage, violating the established landing weather criteria.

A second Florida landing opportunity on orbit 249 is available today at 8:39 p.m. EDT (0039 GMT) for the return of the orbiter and its seven astronaut crew, including French astronaut Leopold Eyharts who is returning from a stint on the International Space Station as the Expedition 16 Flight Engineer.

The next crucial event in the timeline for a landing on tonight's second opportunity is the 'Go for de-orbit burn' decision to be made at about 7:13 p.m. EDT (2313 GMT). If so ordered, the de-orbit burn would take place at 7:33 p.m. EDT (2333 GMT). Weather for the second opportunity is expected to improve with only scattered clouds at about 5,000 feet.

Astronauts Begin Fluid Loading for Landing
26 March 2008 4:53 p.m. EDT


CAPE CANAVERAL, Fla. - Mission Control has given the crew of the shuttle Endeavour the go ahead to begin consuming massive amounts of liquid to better prepare their bodies for the return to Earth's gravity.

Known as fluid loading, the activity is a promising sign that entry flight director Richard Jones intends to attempt the first of two landing opportunities today.

Mission Control is watching a broken deck of clouds southeast of Endeavour's runway here at the Kennedy Space Center to decide whether they pose a threat to today's planned landing today at 7:05 p.m. EDT (2305 GMT).

NASA astronaut Brent Jett, chief of flight operations, is flying a shuttle training aircraft to recon the clouds. Flight controllers want to know how thick they are and whether they hold any moisture. NASA shuttle cannot fly through rain or storm cloud remnants since they can damage an orbiter's tile-covered belly or trigger lightning.

Station's Solar Wing Joint DelaysShuttle's Departure
24 March 2008 8:15 p.m. EDT


HOUSTON - The undocking of NASA's shuttle Endeavour from the InternationalSpace Station (ISS) has been delayed by an unsecured solar wing joint on theoutpost's port side.

The Beta Gimbal Assembly,a joint that twists ISS solar arrays on their long axis to face the sun, on one ofthe station's left-most solar panels is unlatched. Mission Control wants tosecure the solar wing as a standard precaution against damage during anundocking vehicle's departure.

A new latching command has beensent, though it can take up to 15 minutes to take effect. Endeavour wasoriginally slated to depart the station at 7:56 p.m. EDT (2356 GMT).

Spacewalkers Install Experiment,Inspect Gear
22 March 2008 8:09 p.m. EDT


HOUSTON - Spacewalker Robert Behnken has successfullyinstalled the first part of a stubborn materials experiment while his orbitalwork partner Mike Foreman discovered an apparent divot on a damagedsolar array gear outside the International Space Station.

"I feel like this is a divot,"Foreman said, as he passed a wipe cloth over the area. "I feel a littleroughness as I rub it over there, it doesn't feel like a protrusion."

The gear, known as a Solar Alpha RotaryJoint, has been damaged by metal grit that has gummed up its race ring. It isdesigned to rotate the station's outer starboard solar arrays like apaddlewheel to track the sun, but has been crippled since late October.

Behnken, meanwhile, is tackling the secondpart of the experiment, and ready to bang in stubborn latching pins with ahammer if required.

"It might be hammer time," he said.
