QUOTE (Stephen @ Aug 11 2008, 04:47 AM)  ...Will there be enough time for the people in charge of designing and building those to digest the experiences of Phoenix and make any appropriate changes... I think the major lesson will be learning how a part "not manufactured to specifications" finds its way into a flight instrument and its crippling effects remain undetected in testing. Without this unfortunate circumstance nobody would be talking about the need for a pry bar. |

QUOTE (MahFL @ Aug 11 2008, 10:18 AM) Did you see the heavy duty drill they have on MSL ? Speaking of tools, nice drill ya got there... This was interesting: QUOTE The drill is so strong it can hold the rover in place even if all six of its wheels slip on a 20-degree slope. If the drill gets stuck in a rock, the rover can hammer and spin the drill to pull it back out. As a last resort, the rover can release the drill bit and replace it with one of the extras on board. Hammer*, drill, and detachable bits! Next thing you know, they'll add pry bars and brushes! (*I know, it's not really a hammer, but they used the word "hammer") |

Do you know if Phoenix is going to use all 8 TEGA ovens it has or 7 of the 8. Is it going to keep one without a sample soil, for using it as a test cell? do you know if the next TEGA samples will be ice or soil samples? is there any meaning aquiring an ice sample for MECA?

Don't know.
Yes, using the ceramic blank on the deck Don't know And no - you don't want Ice in MECA - as it will dilute the chemistry onboard. Doug |

The ceramic blank is with the other 8 TEGA ovens or it is alone on the deck? when are they going to use it? -------------------- "It`s one small step for a man. A giant leap for all mankind!" Armstrong, Apollo 11, 1969.

It's on the lander deck - they will have to get it with the rasp. As for when....at some point between now and the end of the mission.

I thought the ceramic blank was only going to be used if some organics were found in one of the samples.
Have I missed some more exciting news  Roy |

Thanks Doug
I was going by a paper on the organic free ceramic block from quite a while back and must have missed that press conference. Roy |

They may test the blank in case organics are detected during data analysis after the data gathering portion of the mission is complete, to avoid the situation of seeing evidence for organics months from now with no blank data to compare it to.
edit: Just my speculation on why they would test the blank even if no organics are detected before hand. If, in fact, they do that. |

QUOTE (peter59 @ Aug 15 2008, 12:24 AM) Looks open to me. And in the same way number 0 -- I mean #4 -- was. One side all the way, the other partial.(If you look closely, it's also open in the image you link, just cut off in the image.)
