Following a NASA Constellation budget review – which found the program has a short term deficit of $700m – managers have presented a re-aligned development and test flight schedule, in an attempt to protect Orion’s debut mission to the ISS in 2015.
Huge amounts of Constellation related insider news, presentations and videos – THE most comprehensive place to follow Ares/Orion development – are available for download on L2. See list at the end of this article.
All of this article is based on documented L2 information. For an overview of how L2 works, **click here for sample**
The reason for the changes relates to additional costs associated with the challenges of Ares I’s development, creating a shortfall of funds for the financial year period 2008 to 2010.
The first hint of a problem was noted in a memo sent to managers at the start of the week, noting some of the slips – and their association with the budget review.
‘Cx (Constellation) program held an all day budget review to establish guidance. Ares 1-Y slipping one year; Orion-1 slipping nine months. Formal guideline package coming soon,’ noted the memo. ‘No new definition for lunar phase, so minimizing lunar budgeting efforts. May do lunar budget this summer after architecture settles out.
‘Working new schedule with slips in Cx dates. May combine some of the test flights. Highest instability is schedule/content of test flights. Bring forward business cases for investments now to save on future ops.’
However, the full extent of the fallout caused by the review is seen in a very recent presentation that was produced to overview the schedule changes.
‘Resolve around $700M CxP resource shortfall FY (Financial Year) 08 through FY10. Establish minimum annual carry out ($s) to improve financial management posture year to year,’ noted the presentation dated Jan, 08. ‘Align project budgets with approved technical plan – add selected Level 1 IOC (Initial Operational Capability) / ISS Ops threats.
‘Maintain internal plan of Orion 4 (FOC – Full Operational Capability) in Sept 2014. Preserve agency commitment of IOC in March 2015. Maintain Human Lunar Return (LSAM 2 / Orion 15) target of June 2019. Maintain Surface Systems and Lunar Outpost wedges. Incorporate Test and Evaluation proposed lunar mission manifest changes.’
The plan spreads test and development work well into the next decade, with only Ares I-X – rumored to be close to a delay itself, though denied by NASA – and the abort tests occurring while the shuttle continues flying. Ares I-Y moves to 2013, while all the Orion test flights are conducted in 2014.
‘IOC (Initial Operational Capability) manifest changes: Holds Orion 4 (FOC – Full Operational Capability) but reduces launch spacing from six months to three months for flights Ares I-Y thru Orion 4 (FOC). Moves Ares I-Y 12 months, Orion 1 nine months, Orion 2 (IOC) six months and Orion 3 three months,’ added the presentation.
‘No schedule constraints – can achieve initial production rate of four units in one year. No additional infrastructure required. Slipped start of production / ops build-up.’
As a side note, the first Orion bulkhead – fabricated from 2195 Al-Li material left over from the External Tank program – was shipped on Thursday, by AMRO Fabricating Corporation, California.
Other notes of interest in the presentation relates to the lunar element of the Constellation plan, with a change to the Ares V-Y test flight, an unmanned Orion 13 mission that will be a fly-by of the moon, and confirmation of the nozzle extension to Ares I for lunar mission – though Ares I’s roll past missions to the ISS is under evaluation due to performance issues.
‘Lunar Sortie manifest changes: Replaced EDS (Earth Departure Stage) and EDS Engine mass sims with flight production units on Ares V-Y. Removed crew from LSAM (Lunar Surface Access Module – Altair) 1 / Orion 13 mission. Added Ares I First Stage nozzle extension to support LSAM 1/ Orion 13 mission.’
Not mentioned in the document are other related delays associated with Constellation, according to sources, such as Ares I work on the VAB (Vehicle Assembly Building) – delayed by at least a year. The start of the full conversion of Pad 39B to the Ares I configuration – slipping a year.
The new ML (Mobile Launcher) – slipping a year to 18 months. Altair development – slipping two years, and Lunar applications (the Lunar Habitat) – slipping at least two years.
The re-alignment plan – according to the presentation – is part of a long process, which started on January 9, and will continue for some months, as Constellation carry out ‘face-to-face reviews’ with each of its related departments.
