NASA expect the results of the Soyuz TMA-11 investigation a few days prior to May 31

I didn't have a chance to watch briefing yet - but how does the above match up with:

Gerstenmaier also noted that he doesn't expect a lot of additional information on the Soyuz investigation between now and the launch date.

John44 will post the entire briefing later tonight. Gerst confirmed the statement I made.

Thanks - I'm just curious how he thinks they won't get much more info if the investigation has another week to go... Can't wait to hear Marcia's questioning, sounds like it'll be the highlight of my evening :)

I parsed what he said badly; here's the direct quote: "...there's not going to be a major breaking piece of information that comes in between now and launch that would change where we're headed..."

The best way I can summarize that is:

1) Gerst went to Russia last week. Happy with the investigation so far.
2) There will be results at the end of the month, he said. Russians going at their pace and they will inform of anything amiss during the investigation. NASA won't pressure them.
3) End of month info may be a draft or a latest.
4) What they'll know at the end of the month won't be increased dramatically in the week or so afterwards.
5) Thus delaying the launch would have no benefit, and would cause problems with scheduling etc.
6) They are happy with Soyuz as a rescue vehicle, but not yet as a nominal return vehicle, he said (I know that is strange, but assuming he means evac and you'll take your back up plan whatever).
7) If something comes up that says it's not safe, they have a plan where they will come back with eight on Discovery.

During the presser, he said they'd done a PRA on the risk of an emergency evacuation of the ISS over a six-month period and it came out to 1 in 124.

Thanks for the summary - I know how paraphrasing on the fly can be ;) (That thread got quiet in a hurry!)

Anyways he did go to more lengths about that with the 124 pressers - where he explained that you put that on the risk matrix, and if you have a leak that will kill the astronauts he is comfortable in using Soyuz for emergencies. He just didn't want to use it for switching docking ports. Sounds like that's not changing, which is good.

Can a DPS type please explain the 2-1-1 split referenced in today's article? (the signature that led to the R/R of the failed MDM)

I'm assuming it was a 4-GPC G9 redundant set initially, and two failed out -- one to G9 common set (?) and one to Ops 0 (?)

(been a while since I had to exercise my DPS muscles, so forgive any faulty guesses!)

It's the fourth time I've mentioned it in articles over the past week, one of those included a wider explanation (based off the superb explanation from an engineer on 124's flow thread on L2 - I say that as you're on there, so PM me if you missed it).

Anyhoo, based on what I've got :)

http://www.nasaspaceflight.com/content/?cid=5424

"The fault tree shows that the GPCs - which read data and send commands to the MDMs - first encountered the problem when GPC 4 received erroneous (non-universal I/O Errors) data, which did not match the other GPCs in the redundant set. As programmed, GPC 4 was voted out.

Three seconds later, the same thing happened with GPC 2. At that time GPCs 2 and 4 were powered down and an MDM FA2 BITE Status Register (BSR) read was performed on MDM FA2 port 1, causing GPC 3 to fail out of set with GPC 1. This is known as a '2-1-1 Split'.

At that point, GPC1 was operated in simplex mode to obtain more data. Engineers terminated the work in process and powered down the vehicle for the changeout of the suspect MDM. "

This is of course open to a additional from those in the know, just didn't want it to look like I mentioned it in passing on today's article :)

No worries Chris -- I did see the references in the articles (and in one of your L2 posts), but I missed the explanation.

For those of you who are interested in what the crew is up to here is a portion of my update from Interspace News (http://www.interspacenews.com).


Crew Training Activities Completed Last Week
Entry Simulation:  This was a4 hour integrated simulation of re-entry and landing procedures conducted last Monday in the Motion Base Shuttle Mission Simulator at the Johnson Space Center in Houston Texas.  Each run began at around 200,000 feet and concluded with a simulated landing at the Kennedy Space Center in Florida.  Typically 3 to 5 separate runs will be accomplished during a 4 hour long session.
L-10 Day Bench Review:  Discovery’s astronauts conducted a physical inventory and inspection of the tools and equipment they will use during the mission 3 planned spacewalks.
Post Insertion Simulation:  This was a six hour long simulation of the activities the crew and mission control team will follow after the shuttle reaches orbit.  The Post Insertion timeline is designed to change the shuttle from the launch configuration to the on-orbit configuration.  This was a “suited” session – meaning the crew wore their bright orange launch and entry space suits – that began at T-9 minutes before launch and ended with the crew in orbit.  Post Insertion procedures include activities such as the loading the flight computer with the “on-orbit” software, opening the payload bay doors, stowage of the launch and entry suits, and activation of the galley and toilet.  
FDF Crew Review:  Discovery’s crew performed a review of the actual Flight Data File Checklists and Handbooks that they will use to perform the mission.  The Flight Data File is being shipped to the Kennedy Space Center in preparation for launch.  The crew will have another opportunity during the L-2 Day timeframe to check the documents for typos, procedural errors, errors of omission, and to make any final notations prior to launch.
Final NBL Run:  A final run thru of the missions first spacewalk (EVA1) was conducted in the 6.2 million gallon swimming pool at the Neutral Buoyancy Lab located at the Sonny Carter Training Facility.  The 40 foot deep pool allows the astronauts to work with flight sized hardware, in a simulated weightless environment, as they rehearse the procedures they will follow during the 6.5 hour long EVA (extra vehicular activity).
 

Crew Training Activities Planned For This Week
Shuttle IFM Class:  The Astronauts will have a final class on space shuttle in-flight maintenance procedures.
Ascent Simulation:  On Tuesday the crew will participate in their final integrated simulation with the Mission Control Team.  The 4 hour long session will take place in the Motion Base Simulator and will cover launch and abort procedures.
L-10 Day Flight Physicals:  Discovery’s astronauts will receive their launch minus 10 day flight physicals on Wednesday.  The routine examinations will include blood draws, physicals, and data collection for in-flight medical experiments.
Crew Quarantine:  Following a couple of days of off time, all seven astronauts will enter crew quarantine at the Johnson Space Center’s Crew Quarters.  Officially known as Health Stabilization, Quarantine is intended to minimize the crew’s exposure to common illnesses such as cold or flu by limiting number of people who have direct contact with them during the final days leading up to launch.  Only personnel specifically cleared by the NASA Flight Surgeon office are allowed to have direct contact with the astronauts.

7) If something comes up that says it's not safe, they have a plan where they will come back with eight on Discovery.

Just wondering how this would be effected. Discovery is currently configured with 7 crew seats. If they needed to return 8 crew, and decided on that approach prior to launch, would an 8th crew place be able to be fitted while Discovery is on the pad (without rollback)? And if the decision were made after launch, what then?

Well, the Mission Specialist seats are installed at the launch pad just prior to launch. The MS seats are detachable to provide room for the processing teams to maneuver inside the vehicle during OPF, VAB, and pad processing and for the crew to have room to work and live in the vehicle once in space.  The seats are usually only installed for TCDT, Launch, and Landing operations. I am 99% certain that the mid-deck is capable of supporting 4 MS seats without any major reconfiguration work.

Furthermore, if the decision on whether or not to remove US presence from the station had to be delayed for some reason until during the flight, an extra seat would be flown just in case. NASA would NOT launch with only seven seats if the possibility of needed eight was on the table.

Press Kit for STS-124 is online!

I've just finished reading all of it and wow! This is the first press kit in ages where the text hasn't been copied and pasted from the previous mission! It was very well written indeed, plenty of interesting info.  :)
Entirely agree. And not only that, Nasa dot gov is tricked out in bells and whistles like never before, user friendliness included. Took them a hundred years to get there, but better late than never!

The Nasa website is starting to give the free, non-L2 part of this website a run for its money. However, I will always come here first. Reason, the screen names here whom I recognize for being so forthcoming and trustworthy when answering questions!

Not sure about that. One decent press kit doesn't give this site a run for its money on the news site, which has far more interesting stories than anything I've seen on nasa.gov. Though it seems you're only talking about the forum, and nasa.gov doesn't even have one of those. I come here for the news site www.nasaspaceflight.com and L2 and nothing comes close to on that count.

NASA.gov isn't competition.

Back on topic. There was an incident noted - which started back in the OPF and during the VAB lift to veritical, in Discovery's aft. Nothing that will delay launch we think, and I'll be writing it up.

Relates to an Emergency Life Support Apparatus (ELSA) unit that was left in an avionics bay, when it shouldn't of been, and obviously relocated during the lift. Slight damage caused, but could have been a whole lot worse.

While we're waiting for the write-up, here's what an ELSA apparently looks like:

Looks like a soft item that might not do too much damage bouncing around on the inside, not like an oxygen tank ...

It'll be tomorrow when I run with it as I'm waiting for follow up facts. Currently it's a large part of the L2 report for processing (Wednesday) and a Flash report. Best to hold a bit and get the full picture.
