Thread: Space Shuttle Atlantis STS-122 Launch

Space Shuttle Atlantis STS-122 Launch - HDNet 3:30 Pm Est 12/06
The seven astronauts aboard Atlantis will begin a planned 11-day mission to install the European-built 'Columbus' laboratory. Live from the Kennedy Space Center's launch pad 39a on Cape Canaveral, Florida.

Today's launch scrubbed due to fuel sensor issue. Rescheduled for 12/07 at 4:09 EST.

Maybe Sunday...

And if not Sunday, then Monday. If both are scrubbed, the next launch window is the following Thursday.

Technically no...the launch window itself is open every day until 12/16.

If they attempt Sunday and Monday then they need a 72 hour turnaround to top off the cyros.

The new LCC for tomorrow is that 4/4 ECO sensors must be working to attempt a launch. This is increased from 3/4 because when this situation has occured before (STS-114, STS-115), all 4/4 ECO's passed during the second tanking attempt.

If any of the ECO's fail tomorrow then we probably won't see a launch during this window. It would probably be decided that a repair or investigation is necessary, which most likely could be done at 39A, but would take longer than the rest of the launch window.

If STS-122 is delayed into January, STS-123's launch date in February is not affected.

Weather is looking fine tomorrow.

NASA scrubbed today's scheduled launch (same issue) and is standing down for a few weeks to try and figure out/resolve the fuel sensor issue.

Next possible date they stated that a launch may occur is Jan. 2nd. 2008.

Dang.... last launch and flight was too perfect I guess...

Yeah, those were my thoughts too. Last launch was flawless. But when you've got a craft with over 2 million parts, I imagine getting it 100% every time is really a tough task...

Partially the same issue, but it's worse. An LH2 sensor failed during tanking, but LO2 sensor 3 also failed as dry when it was really wet. This is the first ever problem with an LO2 sensor.

Looks like any investigation or repairs will take up the rest of this launch window. If a rollback is required, I think we'll be seeing a week or two into January at the minimum. If these activities can be completed at 39A, it may be shorter.

EDIT: LO2 sensor does not seem to be a problem. Was most likely a console issue. LH2 is still a problem. MMT debating whether or not this area is safely accessable from pad. Looks like they will try at the pad.
