I'm hosting this week's Cosmoquest Astronomy Hour on Google+. Rather than having a special guest I'll be speaking myself about what's going on with Curiosity, and will leave lots of time to answer people's questions. Join me at 1600 PDT / 2300 UTC at cosmoquest.org/hangouts. I'll embed the video here when we go live; or you can come back to this post after it's over to watch the replay. Feel free to add comments here with questions you'd like me to answer!

Cosmoquest Astronomy Hour, Sept. 12, 2012: Curiosity update

Emily Lakdawalla and Fraser Cain talk about the status of the Curiosity mission at about sol 37, with Fraser asking Emily audience questions. At the time, Curiosity was wrapping up the commissioning of its robotic arm with its MAHLI and APXS instruments.

Hi, I know that Curiosity contains a lot of improvements upon earlier rovers like Spirit and Opportunity. But I was wondering - are there things that Spirit and Opportunity do better than Curiosity?

I am not sure if these questions will be answered in today's JPL press conference, but I am very curious about ChemCam results. I have not heard anything since a Roger Wiens talked at a press conferences a couple (?) weeks ago. I saw the raster but did not see any results. Also has ChemCam been sampling all along the way? Has it been able to detect any sedimentary deposits?

Can you clarify a point for me about Opportunity at Cape York? Has it actually sampled phyllosilicates there (with APXS?) or does the team just assume that it is currently on clay outcrops based on CRISM data?

Any news on results of SAM for methane? I bet we're all pretty curious about whether or not the source can be determined by this instrument. Thanks!

The chemcam camera seems to be a terrific standalone camera/telescope. Are there plans to use it for long distance photography without the spectroscopy?

Hi Emily: Two questions: This is the first nuclear powered rover vehicle. The primary mission is one Martian sol. What is the expected life for Curiosity given that it's nuclear powered? Curiosity has those dust covers on its camera lenses. Do the dust covers cover up when the cameras aren't photographing? I'm reading the 'Wool' science fiction stories which incorporate the need for persons to go out to clean dust off camera lenses outside their shelter on an inhospitable Earth. Thanks for all you do!

Interesting video. The Greek letters on the calibration target "gamma-delta-beta-gamma" are indeed a Caltech reference, signifying "G**-da**-Blacker-Gang". Blacker is one of the Caltech "houses", which are residence dorms, not fraternities, as there is no Greek system at CIT. More info at http://www.ucolick.org/~sla/dei/ "DEI" is another common bit of CIT graffiti--it is said to be on several space probes. --CIT '81 (Ricketts, which seems to have no trademark abbreviation)

@Frederick: Regarding ChemCam, it's been sampling quite a bit, based on the pictures in the MSL raw images site. The reason we haven't heard anything more is probably because they're spending a lot of time carefully calibrating the instrument. There's never been anything like this on Mars before, so they want to make sure they know how to read the results.
