lets hope everything is on track for delivery! one slip most likely means missing the 2009 launch date... <div class="Discussion_UserSignature"> </div>

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Delayed to 2011...Too much risk for 2009. <br />Posted by MeteorWayne</DIV><br /><br />scribblenotes:</p><p>It has been decided to delay until the 2011 launch window (Oct-Dec 2011).</p><p>While they may only miss the 2009 window by a day or a week or a month, they will not be ready to risk the mission in time for a 2009 launch. The next opportunity (haha) is 2011.</p><p>Anomlies in actuator motors are the current (haha) unresolved problem, and it would be too rushed to try and launch by 2009. There are 31 on the MSL, 60 flight ready will be delivered and 45 engineering models. Only 1 of the flight ready ones have been delivered, and only 19 of the engineering models.</p><p>Bottom line, delivery delays, problems in testing, time for proper lifetime testing, etc. They might be able to do it by 2009 but it would be rushed, and you only get one shot to have it all work. Better to delay, give more opportunity to resolve problems and more extensive testing.</p><p>Developmental delays:</p><p>Avionics, Actuator Controllers, Actuators, Sample Handling (lessons learned from Phoenix)</p><p>What is an actuator? Motor/gearbox assemblies that drive the wheels, operate the joints, handle samples, etc.</p><p>Some of them have over 500 parts.</p><p>Most recent problem is excesssive braking, either drag when not supposed to be engaged, or inability to unlock the brakes.</p><p>Don't understand the problem yet, might next week, but might not. Basically, let's not rush, let's take the extra 26 months and make sure we are confident the vehicle will work.</p><p>Most of it is built and delivered, undergoing some sytem environmental testing now.</p><p>More testing and repair is not a bad thing...replaceing suspect components, welds, solar cells.</p><p>The delay will add ~ $400 million to the lifetime cost, but part of that is recovered from funds not used in 2009 and 2010. Current Lifetime mission cost $2.2-2,3 billion.</p><p>This is a Cassini Class mission, not a Phoenix class one.</p><p>There will be some pain in Mars and Planetary science to accomodate this slip and budgetary adjustments, but it's far better than rushing or cancelling the mission.</p><p>Another announcement, US and ESA have&nbsp;committed to work together toward a US/ESA sample return mission. Far future. Nobody can afford such a mission ($5+ billion) alone.</p><p>Delay will also allow time for two upgrades, a cleaning system, and examination of sample handling issues learned from Phoenix.</p><p>I'll be back to fix typos.</p><p>MW</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Thought so! Very unfortunate, though I do understand their reasons for doing so. 2 years is a long time to wait... <div class="Discussion_UserSignature"> </div>

He wrote: "The orbiting assets that are expected to be available to support MSL operations when it arrives at Mars (on the revised schedule) include MRO, Mars Express, and Mars Odyssey. Although two years later, it is still expected that these orbiters will be in place and available for communications relay support for MSL. Having multiple relay-capable orbiters in place allows the continuation of MSL support if one (or even two) of them should become inoperable. In the very unlikely event that all three orbiters should become unable to provide comm relay support, the MSL rover still has the ability to utilize direct-to-Earth (DTE) communications. Albeit slower, the MSL mission could be completed utilizing the DTE link only." </p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
