Nuovi probabili cambiamenti al "Launch manifest" per i prossimi lanci

Sembra probabile che lunedì prossimo durante una riunione del Manifest Summit verranno effettuati alcuni cambiamenti al calendario per il 2007, che era comunque stato stilato in via provvisoria prima delle ultime due missioni. Mentre sembra probabile un anticipo della missione di dicembre (sts-116) potrebbe slittare ad aprile quella di febbraio, per i problemi riguardo l’avvicendamento della missione STS-300 che deve essere sempre disponibile.

huttle manifest re-alignment expected By Chris Bergin, 10/10/2006 9:32:00 PM

NASA is preparing for - what sources claim will be - major changes to their Shuttle launch manifest at a summit meeting next Monday.

The Manifest Summit will involve “everyone” - according to a memo acquired by this site, which will result in changes to launch dates. STS-117 already being noted by sources as moving to later in 2007.

While the next Shuttle mission - STS-116 with Discovery - is already tight on the processing flow, Atlantis’ STS-117 is also struggling to make its February 9 LON (Launch On Need) target in support of her sister.

The primary mission, STS-117 - with a NET (No Earlier Than) launch date of February 22 - is understood to be moving to April. There has been no official note on how this relates to STS-116 still being able to launch in December, especially with the relation to the LON requirements that are crucial to allow Discovery to launch with the support of a rescue mission.

The move of STS-117 - if confirmed - is noted as due to the tight processing flow with Atlantis affecting the availability of a slip down the launch window, subsequently conflicting with the launch of the Russian Soyuz TMA-9 on March 9. Atlantis has to be undocked from the ISS before the arrival of the Soyuz.

This appears to be a critical factor, with sources speaking of an agreement between NASA and the Russians on the April switch for STS-117.

Other issues are understood to be in play, such as next month’s decision on the modification to the Ice Frost Ramps (IFRs) on the External Tanks - which will relate to ET-124 (STS-117’s tank), plus the ISS CCS R6 software upload - which will require crew training.

However, the Shuttle Manifest Summit refers to all future flights, especially in 2007, but inclusive of the final salvo of missions prior to the 2010 retirement date of the orbiters.

'We have scheduled Monday, October 16th to have a Manifest Summit and (we) are looking at about 3 hours (for the meeting). As you know, there are some manifest disconnects in calendar year ‘07,’ said Shuttle manager Wayne Hale, in the memo acquired by this site.

While it would be unfair to class any changes to launch dates as delays, given all NET dates are used only as processing guidelines, Hale also made a point of mentioning the current mission targets do not support - or match - the current NASA budget cycles for the Shuttle program. The tone of the memo also holds the potential some flights may be cancelled, although that has never been hinted at in recent months.

'For some time we have been carrying a FAWG (Flight Assignment Working Group) Manifest that does not match what is in the budget cycle or in a POP Cycle.

'I would like to clear up disconnects in the '07 manifest and then look at out-years '08, '09, and ‘10 and try to align with what we really think we will fly with what the budget folks have been working with. To that end, everybody is involved. The Randall Adams organization (FOIG) has been involved.’

Hale also noted what the main processing concerns are to the current flow, picking out the flow of External Tanks and Orbiter processing as some of the better known challenges that NASA are trying to mitigate. However, Hale ‘expects’ changes to the made to the current manifest after this summit meeting.

'Everybody ought to plan on participating on Monday morning. In the near term, motor, booster, and engine are in good shape. It will probably be tank, ground processing, Orbiter, plus some Space Station considerations that are going to be prime discussers for '07.

'I do expect to come out of that Monday meeting with some adjustments to the ‘07 flight schedule, in particular.’

One can only speculate what changes will be made - bar STS-117’s change, which has multiple sources claiming the move. However, It is possible the changes would move the Hubble Space Telescope servicing mission, STS-125 (HSM-04), up the manifest into 2007, which has been noted as desirable on NASA memos for some time. A decision to approve the mission is set to take place this month.

Come annunciato è stata proposta una piccola revisione ai lanci del prossimo anno, confermata la partenza per il 7 dicembre della STS-116, l’unico dubbio rimane quello della concomitanza con un lancio sempre dal ksc di un payload militare con un Atlas che potrebbe far slittare il lancio dello shuttle di qualche giorno.
La STS-117 è stata spostata dal 22 feb. al 16 marzo, in quella data però farebbe slittare il lancio della soyuz, se i russi non volessero spostarlo la 117 slitterebbe al 23 dello stesso mese. Per la STS-117 potrebbero anche debuttare le modifiche alle “ice-frost ramp” e se così fosse potrebbe essere richiesto un lancio diurno per documentarlo con riprese video, questo farebbe slittare il tutto al 20 aprile.
Per la STS-118 c’è solo un piccolo spostamento dal 11 al 28 Giugno, per la cronaca farà parte dell’equipaggio Barbara Morgan, che fu la backup di Christa McAuliffe, 20 anni fa, nel programma “teacher in space”, finito tragicamente pochi secondi dopo il lancio…
Viene poi la STS-120 dove il nostro Nespoli sarà dell’equipaggio, che viene spostata dal 9 Agosto al 7 Settembre, ma anche qui è possibile una concomitanza con un volo Soyuz.
Per le successive si sono fatte delle ipostesi, con il lancio del Columbus sulla STS-122 confermato per il 17 Ottobre (salvo problemi con le fasi di montaggio delle missioni precedenti) e la STS-123, con Kibo, spostata all’8 Dicembre e la STS-124 al 29 Febbraio 2008.
Rimane in programma per il 17 Aprile 2008, in attesa della conferma definitiva, attesa per fine mese, la STS-125 per Hubble.

Queste sono le successive:

06/19/08 - STS-119: Outboard starboard truss segment and arrays
08/21/08 - STS-126: Station resupply; last flight of Atlantis
10/09/08 - STS-127: Kibo exposed experiment facility; logistics
01/15/09 - STS-128: Crew accommodations; six-person crew capability
04/09/09 - STS-129: Logistics flight; last flight of Discovery
07/09/09 - STS-130: Logistics flight
10/01/09 - STS-131: Contingency flight
01/14/10 - STS-132: Node 3, cupola; last flight of Endeavour

Meglio essere cauti e non rischiare niente, anche se ritardano qualche missione, io non mi faccio problemi.

Ho ricevuto oggi un articolo della CNN, sembra ci siano problemi con il serbatoio esterno.

Si, è già da un po’ che gira, se parli del problema con i limiti di tempo che sono molto rosicati, soprattutto per l’invio in tempo utile del tank di scorta al ksc, se invece sono problemi “nuovi” non ne so niente…

Queste sono le ultime di ieri da nasaspaceflight.com:

On the ET front, MAF (Michoud Assembly Facility) and Lockheed Martin and pushing ahead with the next two tanks due to arrive at the Kennedy Space Center, namely ET-124 - required for Atlantis' STS-117 and LON-117, plus ET-117 - set to fly with Endeavour's return to flight mission STS-118.

'ET-124 - Tank due out December 17, 2006. No major issues, and production activities generally on schedule. Critical path still thru bipod mods. RTF (Return to Flight) mods in progress. Started grip lip spraying. Assessing other areas.

‘ET-117 - This is next tank following ET-124. Vertical in Cell A. Using accelerated production flow thru Cell A, and are on schedule. Completed most sub work in plant, including pocket spray. Puts them in good shape for upper spray next week.’

Interestingly, while NASA claim the changes made to the Shuttle manifest relate to ET backlog, Lockheed Martin appear to be picking up the pace, noting that ‘nine tanks (are) actively in production,’ at MAF.

The other major point of interest with the tanks is the upcoming final decision on the IFR (Ice Frost Ramp) design, which will affect around three or four of the ramps, with the aim of further mitigating foam liberation concerns.

‘On ice/frost ramp testing, completed series of tests with no collars Thursday, and first series of tests with collars Friday,’ noted the report. 'Both tests successful. Will run another series of tests with collars.
