Discovery Does a Backflip
11 December 2006 4:08 p.m. EST
HOUSTON – STS-116 commander Mark Polansky is guiding the shuttle Discovery through a nose-over-tail backflip to allow the three-member Expedition 14 crew aboard the International Space Station to snap photos of heat shields on the craft's belly.
The so-called rendezvous pitch maneuver occurred while the two spacecraft were about 600 feet apart and floating about 220 miles above the South Pacific Ocean.
After the flip, Polansky will steer Discovery to about 300 feet in front of the ISS to line it up with the docking port on the station's U.S. Destiny module.

Discovery TI Burn Complete
11 December 2006 2:31 p.m. EST
HOUSTON – STS-116 commander Mark Polansky has successfully performed a Terminal Initiation (TI) engine burn to put Discovery on a rendezvous path with the International Space Station (ISS).
"It's not everyday you get to do an orbital rendezvous," astronaut Kevin Ford said in mission control.
"I'll echo that," Polansky replied.
The orbiter was above the southern Pacific Ocean when the burn occurred.
Discovery is on track for a 5:05 p.m. EST (2205 GMT) docking with the ISS. Before bringing the orbiter to rest at the docking port of the ISS Destiny module, Polansky will guide the craft through a back-flip maneuver so the station's Expedition 14 crew can take pictures of heat shields on Discovery's underside.

Discovery Crew Awake, Prepare for Busy Day
11 December 2006, 9:45 a.m. EST
HOUSTON – Discovery's seven are awake and preparing for a busy day ahead of them that includes the docking of the orbiter with the International Space Station (ISS) and the official transfer of STS-116 mission specialist Sunita "Suni" Williams to the crew of Expedition 14.
"Good morning Discovery, and a special good morning to Suni," NASA astronaut and spacecraft communicator Shannon Lucid said from ground control. "You need to rise and shine because today is the day that you say goodbye shuttle and hello station."
"Thanks, I can't wait to see my new home," Williams said.
Before docking, however, Discovery will first perform an engine burn at 2:28 p.m. EST (1928 GMT) that will put the shuttle on its rendezvous path with the ISS.
At around 4:05 p.m. EST (2105 GMT) STS-116 commander Mark Polansky will maneuver Discovery to a position about 600 feet directly below the orbital laboratory, after which he will guides orbiter through a 360-degree backflip so the ISS crew can photograph the heat shields on the craft's belly for damage. Discovery is scheduled to dock at the station at 5:05 p.m. EST (2205 GMT).
William's will transfer her Soyuz seat liner to the ISS at around 8 p.m. EST (0100 Dec. 12 GMT) and in so doing will officially relieve German astronaut Thomas Reiter as flight engineer of Expedition 14. After the transfer, the other STS-116 crewmembers will begin preparations for the mission's first spacewalk tomorrow to install a new $11 million ISS component.

Shuttle Tanking Nearly Complete
9 December 2006, 2:40 p.m. EST
CAPE CANAVERAL – Fueling of shuttle Discovery's external fuel tanks is two-thirds complete and should be completed within the next hour or so. Tanking was delayed approximately two hours this morning to accommodate a slower than expected burnoff of the fuel already in the tanks.
The seven STS-116 astronauts are scheduled to depart crew quarters for Launch Pad 39B here at Kennedy Space Center (KSC) at 4:57 p.m. EST (2157 p.m. GMT), but the event could be pushed back by about 15 minutes due to the fueling delay, NASA TV reports. A significant time cushion is still in place, however, and barring any technical difficulties, liftoff is still scheduled for 8:47:34 p.m. EST (0147:34 Dec. 10 GMT).
Tonight's weather outlook is still only 30 percent for Go. The primary concerns are low clouds, showers, and high crosswinds that could interfere with the shuttle's ability to make an emergency return flight back to KSC, should such a maneuver be required. The crosswind restriction for a night launch is 15 knots. Current wind speeds range from 15 to 20 knots.
NASA will broadcast Discovery’s launch countdown and planned liftoff on NASA TV beginning at about 2:30 p.m. EST (1930 GMT). You are invited to follow the countdown's progress using SPACE.com's feed, which is available by clicking here.

Space Shuttle Shroud Pulls Away from Discovery Orbiter
9 December 2006, 9:40 a.m. EST
The protective service structure covering NASA’s space shuttle Discovery is pulling away from the orbiter at its Pad 39B launch site at the Kennedy Space Center (KSC).
Known as the Rotating Service Structure, the 10-story gantry shields NASA shuttles from the elements at the launch pad and allows access to the orbiter’s payload bay before flight.
NASA officials told SPACE.com that first motion began at 9:31 a.m. EST (1431 GMT), about 10 hours later than originally planned, as shuttle managers discuss whether to begin fueling Discovery for an 8:47 p.m. EST (0147 Dec. 10 GMT) launch tonight.
A bleak weather forecast, offering just a 30 percent chance of favorable flight conditions, has increased slightly to 40 percent. Among the top concerns are high winds and low clouds over a nearby shuttle landing strip, which must be available during launch in case of an emergency.
Shuttle mission managers were expected to begin discussing whether to proceed with fueling operations for today’s planned launch at 9:42 a.m. EST (1442 GMT). A positive decision calls for fueling to begin at 10:52 a.m. EST (1552 GMT).

Weather is 70 Percent No-Go for Saturday Shuttle Launch
8 December 2006, 11:10 a.m. EST
CAPE CANAVERAL, Fla. – After thick clouds forced NASA to scrub last night's Discovery launch attempt, shuttle mission managers decided to wait 48 hours before trying again. Countdown is set to resume on Saturday at 3:52 a.m. EST (0852 a.m. GMT) at the T-minus 11 hours mark. There is about 6 hours of built-in hold time before the scheduled 8:47 p.m. EST (0147 a.m. Dec. 10 GMT) launch. The weather outlook is 70 percent that low clouds, high crosswinds and showers could delay launch. The forecast for Sunday and Monday are also bleak, at 60 percent no-go. The best day for launch right now seems to be Tuesday, NASA weather forecasters say.
"We still are going to be concerned about crosswinds, but we think Tuesday out of those three days is going to be the best day," NASA shuttle weather officer Kathy Winters told reporters earlier this week.

Discovery Launch Rescheduled for Saturday
7 December 2006, 10:20 p.m. EST
CAPE CANAVERAL, Fla. – NASA will try to launch Shuttle Discovery again on Saturday, December 9 – a 48-hour scrub turnaround. The planned launch time will be 8:47:34 p.m. EST (0147:34 GMT 10 Dec)
A thick layer of low clouds over Florida’s Kennedy Space Center forced a scrub of Thursday night’s launch attempt.
Weather conditions Saturday are forecast to be marginal with just a 30% probability of acceptable conditions for launch – with potential launch rule violations from strong crosswinds, showers and low clouds. Mission managers decided to forego a Friday launch attempt due to a very unfavorable forecast - only a 1-in-10 chance of suitable weather was predicted.

Weather Remains Questionable for Discovery Launch
7 December 2006, 9:10 p.m. EST
CAPE CANAVERAL, Fla. – The countdown is proceeding uneventfully at the Kennedy Space Center as the clock continues to tick down toward this evening’s scheduled launch of Shuttle Discovery on a mission to the International Space Station. The countdown is now holding at the T-9 minute mark – a planned built-in hold.
Dynamic weather conditions along Florida’s Space Coast are giving meteorologists fits and the current conditions at the Kennedy Space Center are now ‘red’ or no-go for launch due to low clouds in the area - it is likely that a final determination to proceed with launch will remain in doubt until liftoff time. Conditions at the Transoceanic Abort Landing (TAL) site in Zaragoza, Spain are now forecast to be within acceptable limits by launch time.
Discovery’s launch time remains set for 9:35:48 p.m. EST (0235:48 GMT 8 Dec), with a 5-minute launch window.
The launch team is not working any technical issues at this time; weather conditions are forecast to remain within acceptable limits for launch. There is an issue with a short-range tracking camera that is being worked at this time – it is not expected to impact the launch attempt.

Weather Improves for Discovery Launch
7 December 2006, 8:35 p.m. EST
CAPE CANAVERAL, Fla. – Weather conditions at Florida’s Kennedy Space Center have taken a dramatic turn for the better and launch officials are becoming more optimistic that the deck of clouds above the Pad 39-B will remain within acceptable limits to allow a launch attempt this evening on a mission to the International Space Station.
The seven STS-116 astronauts, led by veteran commander Mark Polansky, are strapped into their seats, running through their pre-launch checklists and configuring the cockpit for the spacecraft’s ascent to orbit. The close-out crew of technicians are now buttoning-up the launch pad and preparing to depart.
Discovery’s launch time remains set for 9:35:48 p.m. EST (0235:48 GMT 8 Dec), with a 5-minute launch window – a final adjustment of the launch time will be made at the T-9 minute hold to more precisely align with the space station's orbit.
Weather conditions at the three Transoceanic Abort Landing (TAL) sites in Moron & Zaragoza, Spain & Istres, France are still of concern; however, Istres may be within acceptable limits by launch time – at least one of TAL sites must have good weather to support a launch attempt.

Shuttle Discovery’s Hatch Sealed for Launch
7 December 2006, 8:00 p.m. EST
CAPE CANAVERAL, Fla. – Technicians at Kennedy Space Center’s Pad 39-B have closed and sealed Shuttle Discovery’s hatch in preparation for this evening’s scheduled launch on a mission to the International Space Station. Commander Mark Polansky reports that the spacecraft cabin leak checks have been completed.
Inside, the seven STS-116 astronauts are strapped into their seats, running through their pre-launch checklists and configuring the cockpit for the spacecraft’s ascent to orbit. Discovery’s hatch closure was confirmed at about 7:48 p.m. EST.
Discovery’s launch time remains set for 9:35:48 p.m. EST (0235:48 GMT 8 Dec), with a 5-minute launch window – a final adjustment of the launch time will be made at the T-9 minute hold to more precisely align with the space station's orbit.
Launch forecasts remain pessimistic; a thick blanket of low clouds is likely to remain over the launch site and winds are gusting to near acceptable limits. Forecast conditions at the three Transoceanic Abort Landing (TAL) sites in Moron & Zaragoza, Spain & Istres, France are not promising, although Istres may be within acceptable limits by launch time – at least one of TAL sites must have good weather to support a launch attempt.

Discovery Astronauts Strapped-In for Launch
7 December 2006, 7:10 p.m. EST
CAPE CANAVERAL, Fla. – The seven Discovery astronauts are now strapped into their seats in preparation for this evening’s launch attempt from Kennedy Space Center’s Launch Pad 39-B. Commander Mark Polansky, pilot Bill Oefelein and crew are now performing a series of communications checks to ensure that the astronauts can talk to flight controllers and each other during the spacecraft’s ascent to orbit. Discovery’s hatch is scheduled for closure at 7:20 p.m. EST (0020 GMT 8 Dec).
Discovery’s launch time remains set for 9:35:48 p.m. EST (0235:48 GMT 8 Dec), with a 5-minute launch window – a final adjustment of the launch time will be made at the T-9 minute hold to more precisely align with the space station's orbit.
Discovery's external tank is filled with a half-million gallons of super-chilled liquid hydrogen and liquid oxygen. The vehicle is in "stable replenish" mode and its massive fuel tank will continue to be topped-off until launch time.
Earlier, the ice inspection team found no evidence of ice build-up during a comprehensive survey of Discovery, its external tank and surrounding launch pad for ice formation. The two Solid Rocket Booster recovery ships have reported on-station, about 140 miles off the Florida coast, in preparation for launch.
The launch team is not working any technical issues at this time; however, weather forecasts remain pessimistic for a launch attempt this evening. Wind speeds at the launch pad and the nearby Shuttle Landing Facility are being closely monitored as they are gusting close to acceptable limits and a persistent blanket of low clouds covers the space center, although meteorologists have removed the threat of rain showers from their launch time forecast. Weather at the three Transoceanic Abort Landing (TAL) sites in Moron & Zaragoza, Spain & Istres, France is described as “marginal.”

Discovery Astronauts Head to Launch Pad
7 December 2006, 5:45 p.m. EST
CAPE CANAVERAL, Fla. – The seven Discovery astronauts have begun a 20-minute ride in their silver ‘Astro Van’ toward Kennedy Space Center’s Pad 39B where their spacecraft stands poised for launch this afternoon. NASA Test Director Jeff Spaulding has given his permission for the astronauts to enter the spacecraft, indicating that all switches and systems in the cockpit are properly configured for the crew.
The launch team is not working any vehicle or technical issues; however, weather officers continue to closely conditions around Florida’s Kennedy Space Center and the three Transoceanic Abort Landing (TAL) sites in Spain & France where weather conditions are described as “marginal.” Winds at the Shuttle’s seaside launch complex are currently observed as “red” or no-go for launch and meteorologists are concerned that a combination of gusty winds, low cloud decks and rain showers in the vicinity may prohibit a launch this evening.
The countdown has just resumed at the T-minus 3 hour mark and Discovery's external tank is now filled with a half-million gallons of super-chilled liquid hydrogen and liquid oxygen. The vehicle is in "stable replenish" mode and the massive fuel tank will continue to be topped-off until launch time.
Discovery’s launch time remains set for 9:35:48 p.m. EST (0235:48 GMT 8 Dec), with a 5-minute launch window, weather permitting.

Technical Issues Will Not
Delay Discovery Launch
6 December 2006 4:05 p.m. EST
CAPE CANAVERAL, Fla. – Two last-minute technical issues discovered during shuttle tests and inspections have been deemed safe and will not delay Discovery's launch Thursday evening, NASA mission mangers concluded after a two-hour meeting.
The issues involved a brief power surge in circuits responsible for transferring power from the mobile launch platform to the orbiter and an anomalous test result from a batch of adhesive used to glue together segments on the shuttle's reusable solid rocket booster.
But subsequent investigations have determined that the power surge did not damage Discovery's external tank and boosters or the orbiter itself. Concerning the adhesive, the peel test that provided the anomalous result was not a flight-required test and therefore does not affect launch, said NASA spokesperson June Malone.

Shuttle Launch Countdown
Begins Tonight
4 December 2006 2:45 p.m. EST
CAPE CANAVERAL, Fla. - NASA is set to begin a three-day countdown to the launch of the shuttle Discovery tonight at 11 p.m. EST.
The T-43 countdown will include 27 hours, 36 minutes of built-in hold time leading up to the 9:35 p.m. EST launch of the shuttle on Thursday, Dec. 7.
Before that happens, however, another event important for liftoff will take place. International Space Station (ISS) flight controllers are expected to boost the station into a higher orbit today at 4:36 p.m. EST in preparation for docking with the shuttle on Dec. 9. Attempts to do so last week were cut short due to an unexpected shift in the station's orientation. If the afternoon burn does no go as planned, it could cut into the Discovery's launch window, which currently runs from Dec. 7 to 17.
There are some concerns that a low cloud ceiling and showers on launch day could delay Discovery's liftoff by 24-hours.
The five-man, two-woman crew of STS-116 arrived here at Kennedy Space Center yesterday afternoon, jetting in on T-28 training aircraft. The crew, currently under quarantine, are undergoing final preparations for their mission. STS-116 commander Mark Polansky and pilot William Oefelein are also practicing shuttle landing, currently slated for Dec. 19.
