Could Phoenix's arm help push material into that oven?

Phoenix successfully dumped soil onto the screen covering the first oven, but it won't go through the screen.&nbsp; I was thinking perhaps the arm could push it down so we could see what it takes to get the material into the oven.&nbsp; As is, while there are 7 more ovens, we have no way to ensure that any of the samples will go in.&nbsp; If Phoenix can push down on that oven without risking damage to the others, we might as well try as we would otherwise lose that oven anyway. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

And no one thought that having at least one or two ovens with trap doors instead of screens could be useful? <div class="Discussion_UserSignature"> </div>

<p>I can't wait for them to use the shaker again and get sample into the oven so that all this consternation can stop. &nbsp;</p><p>In a worst case scenario, samples will be delivered to the other ovens using methods devised to eliminate the current problem. Only after all the other ovens are used would any drastic measures be considered to get samples into the first oven.&nbsp; By the way, I don't know, but I suspect the scoop could touch the TEGA covers. </p><p>Within a day we will know if the second (only the second!) attempt to shake sample into the oven has succeeded. &nbsp;&nbsp;</p> <div class="Discussion_UserSignature"> </div>

<p>&nbsp;</p><p>Is there any way to disgorge clumps of particles stuck in the screen?&nbsp; I understand it can vibrate the screen to help get stuff to fall through, but if there's a lot of particles that are clogging it up it may become unwieldy.</p><p>Also, how close is the oven to the screen?&nbsp; Would turning the oven on heat up the soil on the screen enough to loosen up any frozen clumps?</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> </div>
