STS-127 Downrange Ops

Weak USB here on 9043.0 kHz, sounds like Cape Radio.

Freedom Star reported on 9132 and 9043 by Jon in Florida.

STS-127 Made It!

Presumably everyone knows by now that the 6th time did it, and Endeavour is on-orbit. Keep listening as the Booster Recovery Vessels do their jobs downrange.

STS-127 Still Go

The STS-127 count is in its final T-9 minute hold, which will last another half hour or so. Launch time is scheduled for 2203:10 UTC.

Weather now only has a 10% chance of preventing launch.

Poor STS-127 Is Trying Again

BTW, this is not the record for scrubs. They've scrubbed 5 times (leak, leak, lightning, weather, weather). Two earlier missions both had 6.

Tanking is complete, and the count is in the scheduled T-2 hour hold. Weather has a 60 per cent chance of allowing launch, but KSC is currently under a lightning watch. Barring further storms, this should expire at 2000 UTC. Launch is scheduled for 2203.

Poor STS-127 Tries Again Today

Poor STS-127 has been postponed 4 times now (hydrogen leak, hydrogen leak, lightning, weather).

They're trying again today. Launch target is 6:51 EDT (2251 UTC).

At this moment, tanking is complete. Astronauts are suiting up.

The weather has a 60% chance of preventing launch. [Corrected from 80% after the weather briefing, but now there are storms forming in the area, so that might be optimistic.]

STS-127 Scrubs Again

Worsening weather caused a 24-hour scrub before the count would have resumed at the T-9 hold. Florida's notorious afternoon thunderstorms strike again.

Next opportunity is at 2251 UTC tomorrow. As Tom Petty said, the waiting is the hardest part.

Now, let there be code.

STS-127 Holding At T-9

This is a planned built-in hold which will last approximately 45 minutes. A rapidly developing weather system inside the radius needed for a return to launch site abort is currently no go. There might or might not be any improvement before the launch window closes.

STS-127 Still on Time

Holding at T-20 minutes. Weather is fine but there's a chance it might violate criteria at launch time.

I just heard Cape Radio making checks with an unknown station.

STS-127 Count Resumes

STS-127 came out of the built-in hold around 2100 UTC. Crew is getting ready to enter the vehicle. Weather shows only a 30% chance of preventing launch.

So far no reports of Booster Recovery Vessels. I continue to monitor 10780 kHz, Cape Radio primary, but so far nothing.

STS-127 Still On Time

Tanking was completed around 1600 UTC, and no leaks were found. NASA TV coverage begins at 1800 UTC though a picture of the pad is up right now. Downrange operations should be on the radio, though I haven't seen any frequencies yet.

STS-127 Delayed Until Sunday 7:13 PM EDT

Lightning strikes around Pad 39A were severe enough to scrub the STS-127 launch. NASA video shows one direct hit to the mast atop the gantry tower. Catenary wires conducted the juice to ground, but systems need to be checked for electrostatic surge damage.

New launch target is Sunday at 7:13 PM EDT (2313 UTC). The Mission Management Team will meet at 8 a.m. Sunday to evaluate the latest data. Fueling of the external fuel tank is scheduled to begin at 9:48 a.m. Sunday.

STS-127 Count On Schedule

No major issues were mentioned at today's mission status briefing. The launch remains scheduled for 7:39 PM EDT (2339 UTC). The Rotating Service Structure will be rolled back at 11 PM EDT (0300 UTC), and tanking will commence around 10:14 AM EDT tomorrow (1414 UTC).

Florida's summer stormy weather has a 60% chance of preventing launch.

STS-127 Gets Go for July 11

Following the successful completion of tanking tests, NASA has set a launch target for STS-127. Technicians replaced parts on the external tank and no leaks were found after it was filled.

Endeavour's launch on the STS-127 mission is targeted for 7:39 PM EDT (2339 UTC) on Saturday, July 11. The 16-day mission to the International Space Station will feature five EVAs. These will complete construction of the Japan Aerospace Exploration Agency's Kibo laboratory. Astronauts will attach a platform to the outside of the Japanese module that will allow experiments to be exposed to space.

STS-127 Launch Scrubbed (Again)

Due to a gaseous hydrogen leak in the same place as last time, NASA has just scrubbed the STS-127 launch. The next launch opportunity is no earlier than July 11.

STS-127 Still On Schedule

Due to thunderstorms, STS-127 tanking began almost three hours late, but the count remains on schedule for the 0940 UTC launch. Range activities should be audible on HF at some point this evening (US time).

STS-127 Count On Schedule

At time of writing, the count was at -8 hours, 14 minutes. Of course, this does not include several built-in holds.

Tanking begins around 0015 UTC tonight (Tuesday in the US). NASA TV will be live.

Launch is still scheduled for 0940 UTC (5:40 AM Eastern Daylight Time). Weather still shows an 80% per cent chance of allowing launch.

NASA Sets Wednesday for Next STS-127 Attempt

Following a weekend of meetings, NASA has resolved the scheduling issues for use of the Eastern Test Range. This means that STS-127's next target launch time is 5:40 a.m. EDT (0940 UTC) on Wednesday, June 17.

The range became available with the rescheduling of the Lunar Reconnaissance Orbiter, or LRO, and Lunar Crater Observation and Sensing Satellite, or LCROSS. Their new launch target, aboard the same Atlas V booster, is the very next day. There are three launch opportunities from Cape Canaveral Air Force Station in Florida on Thursday, June 18: 5:12 p.m., 5:22 p.m. and 5:32 p.m. (2112, 2122, and 2132 UTC).

Sounds like a busy 36 hours for communications on the Eastern Test Range.

STS-127 Postponed At Least 4 Days

According to NASA, the time required to inspect the hydrogen line, effect repair, and pick a new launch target will delay launch for at least 96 hours.

This is the same hydrogen system that gave trouble on an earlier flight. It conducts gaseous H2 boil-off to a flare where it can be burned safely.

STS-127 Launch Scrubbed!

NASA has scrubbed Saturday's Space Shuttle launch after a leak was found in a gaseous hydrogen return line during tanking. The decision to postpone was made at 12:26 AM EDT (0426 UTC). There is no new launch target time yet.
