Does anyone have a scoop on the amount of damage to Atlantis and its tank due to
that hail storm ?
A spaceflight.nasa.gov statement made on the 3rd day of the 16th month mentions
that inspections are continuing and makes no mention of what techniques will be
used for tank repairs. (fix vs replace for instance).
There is mention that the Atlantis flight will wait until after the next Soyuz
trip in April.
While NASA may say "no earlier than april", is there a feel for a "not later
than" date ? Or is June still a possibility for the next flight ?
Should Atlantis be delayed well in to May, can they bring Endevour to the second
pad to start its processing while they put final touches and launch Atlantis ?
How many days after Atlantis lands can they launch Endeavour ? Would both
flights have separate houston MCC crews, or would they need to give the crews
some "rest time" between landing of STS117 and launch of 118 ?
Or is NASA not even going to try to make up time and just reschedule STS118 with
as much delay that STS117 had ? |

according to florida today tank repairs have started. if repairs ecome
impossible a new tank is scheduled for delivery that will delay launch
till june.
given the extent of damage to the tank I think it should go back be
stripped and redone completely, or become a permanent display tank
somewhere.
If they launch with that tank and get a shuttle stuck at station it
will appear the height of reckless and just may sour congress to any
nasa funding. In any case it would likely end shuttle ISS so maybe
thats not a bad thing. ISS without shuttle will have sustanibility
troubles for large parts like Gyros. |

In any case ISS will not be complete by 2010, if ever.
Theres just not enough time to launch the number of flights needed,
and the next accident will show schedule pressure of 2010 the largest
cause......... |

Not as bad as originally thought. Great in quantity but not severity.
Atlantis and the SRBs have already been repaired except for a couple
of hard-to-reach places. The Tank is the pacing item.

Say again? :-)
Quote: mentions

The decision was made this week to repair in place. No destacking
necessary.
Quote: There is mention that the Atlantis flight will wait until after the next Soyuz

Launch is still No Earlier Than April 22 (some say April 23.)
Quote: While NASA may say "no earlier than april", is there a feel for a "not later

NASA has decided to repair ET-124 (the current STS-117 tank) so that
means late April-early May is likely launch target. June would come
into play if they have to switch Tanks and use the Tank meant for 118.
That could still happen if the repairs fail, but that's not the plan
at present.
Quote: Should Atlantis be delayed well in to May, can they bring Endevour to the second

Irrelevant. They haven't started stacking the STS-118 vehicle SRBs
yet, as there is only one VAB High Bay available (HB-3 is down for
door overhaul.) Once 117 returns to the pad, they'll start 118
stacking. The delay won't be all that great, because 118's Tank wasn't
schedule to arrive at the Cape until early April anyway.
Quote: How many days after Atlantis lands can they launch Endeavour ?
The record is 7 days between STS-71 and STS-70 in 1995.
Quote: Would both

A week perhaps. Doesn't appear necessary though. Looks like about two
months between 117 and 118 now.
Quote: Or is NASA not even going to try to make up time and just reschedule STS118 with

The "best guess" right now is for STS-117 Atlantis launching the
second week of May and STS-118 Endeavour being delayed about three
weeks to mid-July. The two-month delay in Atlantis should push back
STS-120 from early September (it was being moved up to late August
before the hail attack) to early November, perhaps late October.
STS-122 probably gets pushed back a month from late November to
mid/late December, with Year End Rollover no longer a restriction.
We're still probably looking at four flights in 2007. Manifests and
Launch On Need scheduling certainly gets a lot easier when you have
all three Orbiters up and running. If you look at NASA's 2008 Shuttle
schedule, there's a whole lot of padding in there for the Hubble
mission, so they should be able to make up lost time without much
trouble...
15 Mar 07 STS-117 Atlantis (S3-S4)
