<p>Judging by the many comments on recent SDC Phoenix stories, there are quite a few people who think that Pheox was a waste.&nbsp; Common objections include:</p><p>1.&nbsp; It should have been a rover</p><p>2. It should have been nuclear powered.</p><p>3 It was badly designed.</p><p>4. It was badly built using sub-standard components.</p><p>5. It performed poorly.</p><p>6. The science goals were downgraded halfway through to mission to make it lookk like a success.</p><p>7. No useful science was achieved.</p><p>8.&nbsp; The public was ignored.</p><p>9. The site names were insulting and&nbsp;juvenile.</p><p>10. It was just a bureaucratic spending exercise.</p><p>11. It was over priced.</p><p>12. The money would have been better spent on other Mars missions (or Ares, Orion, Europa, TPF, Titan...)</p><p>13. No pretty pictures.</p><p>14. Primitive robotics.</p><p>15. Poorly conceived from the start.</p><p>16. Planning flawed by the&nbsp;same system that caused the Columbia disaster.</p><p>17. No new discoveries.</p><span><p>18. Phoenix selected because it was cheap not because it could do science </p><p>19. Phoenix was a waste because its budget blew out from 250&nbsp; to&nbsp; more than 450 million</p><p>Frankly I think all these comments to be ill-informed at best, prejudiced and ignorant might be a better way to describe them.&nbsp; But they are out there, and should be responded to.</p></span><p>I am hoping that some anti-Phoenix people will respond, given how many there seem to be.</p><p>&nbsp;So, who thinks&nbsp; Phoenix was a waste?</p><p>&nbsp;Jon</p><p><em>13 and 14 added in edit</em></p><p><em>Edit 2- 15-18 added</em></p><p><em>Edit 3 19 added</em></p><p>&nbsp;</p> <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

<p>No, I don't think it was a waste. Just to see ice come and go, analyse it, ride around for five months in temperatures ranging from minus 60 to minus 100&deg;C, and the making thousands of pis,&nbsp;to me, looks like already worth the entire project. But the critisism, especially regarding the cost,&nbsp;about a project like this isn't new, for Henry the Navigator had to already&nbsp;put up with&nbsp;it, and the Phoenicians before him. </p>

Is it possible on future Mars missions, for them to attach some kind of wiper to the solar panels to clear some of the dust off? <div class="Discussion_UserSignature"> </div>

Had they thought the MERs would last beyond the 90 days, I'm sure they would have installed wipers.

<p>&nbsp;</p><p>I don't think it was a waste.&nbsp; Sure, there were no "shout it from the mountaintops" discoveries but you can rarely predict such things much less guarantee them.&nbsp; We did learn important things about the composition of northern Martian soil, characteristics of ice formation and weather, and it was a solid engineering success by successfully executing a soft landing, the experience of which can be used for future craft. </p><p>If there was one of your line items that I would agree with though, it would be the nuclear power issue.&nbsp; I would have much rather seen a nuclear powered Phoenix that could operate around the clock and last through the winter, I think it would have given the mission a much better capability to collect and analyze a larger amount of data.</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> </div>
