From which trenches do you think the next TEGA samples are going to be? what will they do with the unsuccessful TEGA-1 Snow White sample? they will leave it as it is or they`ll try to fill it with more sample?

Next TEGA oven doors had clearly failed to open.

Next TEGA oven doors had clearly failed to open. Failed to open fully, right? Oven number 5 I think was the very first where both doors opened partially, but it was successfully delivered to anyway. (Planetary Society Weblog: Phoenix sol 72: Delivery to TEGA oven 5) |

I think Sol 120 Raw Images documents a second delivery from Snow White to TEGA #1. Small sample in the scoop (0749 local time) and the scoop over #1 (0757) and the scoop empty (0825): Before (0717) and after (0750), trench probably Snow White: |

Possible TEGA, maybe oven #2, delivery on sol 122.
Sol 122 Raw Images Interesting white stuff, scoop before (1028 local time), TEGA (1041), scoop after (1047): |

Whoa. Where was all that ice scooped from? No sample source SSI images visible yet.

That's going to be the OFB surely?

Here's some RAC color of the scoop. Hopefully, some made it into the oven. Judging from the post-delivery images, it looks like the darker material stayed in the scoop while the bright stuff mostly fell out.

Good catch, Peter. I'd been wondering how much of an effect the wind has on their sprinkling efforts. They're most interested in the smallest grains which can pass through the screens, but the smallest grains are most affected by the wind. Do they take wind into account in placing the scoop above the ovens?
That exposure is 1/40th of a second if I read the header correctly, which says those particles are moving pretty fast... |

We can see some material missing the target; that doesn't necessarily mean it all missed. Also, two images of falling material presumably indicates a deliberate effort to catch it in the act, so it's success on that count; and if the strength of the wind effect was unexpected, that's a win as well. (Lemonade, anyone?)

This image indicates that the influence of wind must be very significant. Maybe. But it could also be an image taken when the scoop stopped at the end of a left to right swing while vibrating. The material in the scoop funnel seems to be concentrated to the right of the funnel which would imply movement of the particles through inertia when the scoop stopped, with the particles that fell out moving to the right. Inertia rather than wind energy. The CSA Mars Weather Report hasn't been updated since Sol 99 so we don't know what the wind was at ground level. But from the Sol 122 TEGA (1041) image the material ended up on the left of the oven lid as well so delivery would have been on target. Where was this sample from? Ice or salts? |
