I challenge you not to look at this and make a ping/spring/boing happy sort of a noise.

I read that as, "Well, the stuff is in the oven anyway. If we do manage to deliver ice how are we going to interpret the data with a mixed sample? Might as well cook this one up and be done with it."


With regards to Shaka's question, can they determine the H/D ratio from the evolved stuff?
(If they can, the H/D ratio of the ice would be lost since both would probably sublime equally well within experimental error. So they'd need a fresh ice sample in the oven, not a used and abused concentrate.)

Okay, I'm a bit confused.

Peter's comments implied fresh delivery of a dry sample, no? Like oven #0 has spoiled stuff in it. Would they just dump new dry stuff in #0 till it's finally full and then, how do you characterize the result in regard to its context? As NotLurkingAnymore suggests, could #0 just be a delivery test site now? I admit to profound ignorance of the chemistry of all this.

Paul

I would anticipate that they will try and get what is left in the scoop in to top up the oven. This will mean that all the material in the oven will have come from from the rasping of the ice material layer. We know that (water) ice is only a part of this layer. I wouldn't like to guess what percentage, but there seems to be a lot of material left after sublimation. So having got rid of all that pesky haich two oh we are left with some pretty valuable material to analyse. Is it the same as the dry upper layer of the regoloth? What surprises does it hold? If there are any organics then they had a better chance of surviving in the opaque ice than in the regolith. Get some to the wet chemistry lab. What is the Ph of this material? Drop a bit into the OM.

Even if the system does fail after the event at least we will have two separate, and valuable data points.
