STS-133 Booster Vessels Heard on 9132 kHz USB

Both Booster Recovery Vessels, the Liberty Star and the Freedom Star, were just heard on 9132 kHz USB in radio checks with the Booster Recovery Director at Cape Canaveral.

Various listeners in the eastern US have also heard comm on 10780 kHz USB from Cape Radio. The 9132 shore side is a remote transmitter at "Andrews."

Astronauts are currently entering the vehicle.

Weather is now 90% go.

The launch is being blogged here.

STS-133 Counting for 2150 UTC Launch

The STS-133 count remains on schedule at this time.

Fueling of Discovery's external tank is expected to begin at approximately 1225 UTC. NASA TV coverage begins at 1215 UTC.

This flight delivers a storage module and a robot ("R2") to the ISS.

The STS-133 crew members are Commander Steven Lindsey, Pilot Eric Boe and Mission Specialists Alvin Drew, Michael Barratt, Steve Bowen and Nicole Stott. Bowen replaced astronaut Tim Kopra, who was injured in a bicycle accident in January.

Discovery will deliver and install the Permanent Multipurpose Module, the Express Logistics Carrier 4 and provide critical spare components to the International Space Station. This will be the 35th shuttle mission to the station. It is also Discovery's final flight.

The Eastern Test Range uses many frequencies for booster recovery and safety, but some recent ones are 5711, 6751, 9043, 9132, 10780, 11104, 11548, 13212, and 14837 kHz USB.

Weather forecast shows only a 20% possibility of preventing launch.

RELEASE: 11-047

NASA SETS LAUNCH DATE FOR SPACE SHUTTLE DISCOVERY MISSION

CAPE CANAVERAL, Fla. -- Space shuttle Discovery is scheduled to begin an 11-day mission to the International Space Station with a launch at 4:50 p.m. EST on Thursday, Feb. 24, from NASA's Kennedy Space Center in Florida. The STS-133 mission is Discovery's final scheduled flight.

Discovery's launch date was announced Friday at the conclusion of a flight readiness review at Kennedy. During the meeting, senior NASA and contractor managers assessed the risks associated with the mission and determined the shuttle and station's equipment, support systems and personnel are ready.

The six astronauts for the mission will deliver the Permanent Multipurpose Module (PMM) to the station. The PMM was converted from the multi-purpose logistics module Leonardo and will provide additional storage for the station crew. Experiments in such fields as fluid physics, materials science, biology and biotechnology may be conducted inside the module.

The PMM also carries Robonaut 2, the first human-like robot in space, which will become a permanent resident of the station. In addition, the flight will deliver critical spare parts and the Express Logistics Carrier 4, an external platform that holds large equipment.

STS-133 Commander Steve Lindsey and his crew are scheduled to arrive at Kennedy on Sunday, Feb. 20, for final launch preparations. Joining Lindsey are Pilot Eric Boe and Mission Specialists Alvin Drew, Steve Bowen, Michael Barratt and Nicole Stott. Bowen and Drew will conduct two spacewalks to install new components and perform maintenance.

Discovery's launch will occur six hours after the planned docking of the European Space Agency's Automated Transfer Vehicle-2 "Johannes Kepler" to the space station.

STS-133 is the first mission planned for 2011. It is Discovery's 39th flight and 35th shuttle mission to the station. There are two other flights planned before the shuttle retires this year. For the schedule of upcoming missions to the International Space Station, visit:

STS-133 Delayed Until At Least Nov. 30

NASA has called off any possible launch of STS-133 in this window. The next opportunity is November 30, at 0405 EST (0905 UTC).

While the tank was being drained of its cryogenic fuel following discovery of the hydrogen leak, a crack developed in the foam. This will require further examination.

The astronauts have returned to Houston.

Hydrogen Leak Scrubs STS-133

Once again, a hydrogen leak discovered during tanking has forced a launch scrub.

NASA:

Managers Schedule 11 a.m. EDT Meeting to Discuss Scrub Turnaround Options
Fri, 05 Nov 2010 07:25:58 AM PDT

Space shuttle managers and engineers will meet at 11 a.m. EDT to discuss the work necessary to repair a gaseous hydrogen leak and prepare space shuttle Discovery for its next launch attempt.

The earliest opportunity is Monday, Nov. 8, at 12:53 p.m. EST, the last date Discovery can launch in this window. The next launch window for Discovery is Tuesday, Nov. 30 through Saturday, Dec. 5.

At 8:11 a.m., launch was scrubbed because of a hydrogen gas leak at the Ground Umbilical Carrier Plate, or GUCP, an attachment point between the external tank and a 17-inch pipe that carries gaseous hydrogen safely away from Discovery to the flare stack, where it is burned off.

Shuttle launch director Mike Leinbach characterized the leak as “significant,” similar to what was seen on STS-119 and STS-127, although today’s rate was higher in magnitude and occurred earlier in the fueling process.

The external tank is being drained and will be inerted for about 20 hours before it is safe for technicians to look at the GUCP on Saturday.

The Space Shuttle Program Mission Management Team will meet Saturday after technicians have had the opportunity to troubleshoot the hardware. The MMT will determine if it is possible to achieve a launch attempt Monday.

NASA Television will air a news conference no earlier than 1 p.m. EDT with Mike Moses, Space Shuttle Program launch integration manager and Mission Management Team chair, and Mike Leinbach, shuttle launch director.

Weather Delays STS-133 At Least Until Friday

NASA:

Shuttle Launch Attempt Delayed for Weather
Thu, 04 Nov 2010 03:08:24 AM PDT

Managers will delay Discovery’s launch for 24 hours due to weather. Mission managers will meet tomorrow at 5 a.m. [EDT] to reevaluate the weather conditions. Friday’s launch attempt would be at 3:04 p.m. EDT.  [1904 UTC]

STS-133 Count Resumes for Thursday Launch

The Mission Management Team briefing has just announced that the STS-133 count has resumed.  Weather is still doubtful for a launch Thursday afternoon, but the plan is to count down until the time for loading fuel approaches, then assess the weather at that point.

The Rotating Service Structure move was delayed by lightning.  It will take place shortly.  NASA TV coverage begins Thursday morning (EDT).

STS-133 Launch Delayed at Least 24 Hours

NASA:


MMT to Meet Wednesday on Electrical Issues
Tue, 02 Nov 2010 04:21:01 PM PDT

The Prelaunch Mission Management Team wants to give engineers more time to look deeply into two electrical issues from a main engine computer controller that cropped up this morning. Therefore, the launch of space shuttle Discovery on STS-133 has been delayed until at least Thursday. Mike Moses, chair of the MMT, said the problems are believed to be tied to a circuit breaker in the shuttle's cockpit.

Rather than rush the shuttle launch team through an analysis and launch cycle quickly, Moses said he opted to let the engineers work throughout the night on the issue without having to worry about an early morning tanking and Wednesday afternoon launch. The MMT will meet again Wednesday at 2 p.m. EDT and then decide whether to try to launch Thursday. A liftoff Thursday would be at 3:29 p.m. [1929 UTC]

A launch on Thursday is problematic due to a weather front moving into the KSC region. Weather will have a much higher chance of preventing launch.

STS-133 Count Continues

STS-133 is currently in a scheduled hold at T-11 hours.  The Rotating Service Structure will be removed during this hold.

Launch remains on-schedule for 3:52 p.m. EDT (1952 UTC) tomorrow (Wednesday).  Weather shows only a 30 per cent chance of violating constraints.
