    Curiosity Surface Operations

    Love the title. (Borrowed it from NASA TV.) Waiting right now for data back from a low-elevation Odyssey pass.

    And a nice little panorama someone made from the rear hazcam image.

    Crater rim. Cool. And sunset.

    Lots of dynamic range in that image.

    Landing just before night? Does that mean Curiosity gets a nap to get over the rocket lag?

    We got info that they successfully photographed Curiosity from Orbit during landing. The image will be released at 9 : 00 AM, during the next conference

    I wonder how it will look. AFAIK MRO snapped photo from different angle than iconic Phoenix EDL. Is this too much to expect MSL in colored band?

    I personally can't wait to see the photo, as well as a post-landing photo showing Curiosity on the surface (to pinpoint the location). I wonder where's the parachute and the descent stage (how far away it flew)

    Did they say anything on the health of the Rover?

    I can't wait for them to analyze the blueberries!

    Watkins:

    c. 4 am pass: Curiosity in surface nominal mode, everything looks good, go for Sol 1 activities. Mostly very boring - deploying antennas, etc. First priority is communications.

    Showing off the first photos.

    Hoping for front hazcam image in a couple of hours, expecting it to show the mountain at the center of Gale Crater.

    San Martin:

    EDL looked beautiful but have yet to review actual data. Best knowledge of where we landed: just a couple kilometers east of the very center of the landing ellipse.

    Location based on where Curiosity thinks it is. Inertial measurements fit radar almost perfectly - better than the simulations, within a few meters in altitude and less than 1 m/s in velocity. Don't expect to be off by more than a kilometer.

    Milkovich:

    Odyssey not only orbiter listening, also Mars Reconnaissance Orbiter listening, and not just listening but watching. Now showing photo I shared in the other thread, preceded by wider-angle image.

    Image taken 6 minutes after atmospheric entry. MRO about 340 km away from Curiosity. Can see parachute and lines.

    Grotzinger:

    Rear hazcam showing rim of Gale Crater. Scientists impressed by uniform size of grain particles. Hoping in-situ sample would be highly representative of Mars, will do thorough analysis.

    Absolutely amazing...glad I included a "disclaimer' in my previous post. (martian smillee)

    Black line - line of dunes - will be point of orientation. Now looking at front hazcam, think dark line across is those dark dunes. Above it is Mount Sharp. Hazcams already picking up topography.

    Questions:

    S&T: Landing time?

    Will get it.

    LA Times: What's just south of landing site? How far to foothills of Mount Sharp?

    Rather narrow strip of dunes, just a few kilometers away. Interesting part could be as much as 10 km away.

    Don't want to go straight to mountain, want to find a route that's interesting scientifically.

    Register: What happened to "upper stage" that flew off?

    We want to crash it at least 400 meters to the north. Don't get telemetry so don't know. Hope to get image from HiRISE to tell us.

    The HiRISE image is absolutely incredible.

    Nature: Have you looked for heat shield in image?

    No, haven't looked for it in the image. Don't know that we'd be able to see it. Will be taking images of landing site in days to come, especially good ones six and twelve days from now to look for other components.

    Resolution at Curiosity of EDL photo is 33 cm/pixel.

    ??: Blotch in image possibly landing stage impact?

    Could be. Could be dust devil. Too early to tell, would like to take another look. Just starting to trickle down thumbnails from descent camera.

    BBC: How far to rim in image?

    On the order of 20 km.

    Leonard David: How much residual fuel? What was touchdown speed?

    140 kg - lot more than planned for. Reported touchdown speed - 0.75 meters/second, right on the money. 4 cm/sec horizontally. "That's called straight down."

    Easier or harder to image Phoenix vs. Curiosity?

    Curiosity tougher due to positioning of spacecraft, figured 80% on Phoenix, 60% Curiosity.

    USA Today: When first BW, color, panoramas, MARDI images?

    Front hazcam - couple of hours.
    MARDI thumbnails - couple of hours.
    Rest - next few days.
    Single color image/MALI (sp?) imager - about two days from now.

    I said it last night, and I'll say it again...

    Darn clever these Earth people. (proud smilee)

    Space.com: How high a priority to check impact craters from descent stage?

    Would really prefer to avoid hydrazine-filled descent stage. Would have liked to see ballast sites, but they're probably way too far away.

    Done everything possible to fly skycrane away from rover.

    Reuters/Discovery: How many photos so far? When high-gain deployed?

    4 thumbnails, 2 down-sampled, 1 512x512. Deploy high-gain in about 12 hours.

    What soil variations have been seen so far, what are you looking for?

    Bedrock will be local info, soil will be a mix of global influences. Soil has high sulfur content, Curiosity's instruments will provide better insight.

    CBS/Bill Harwood: Does dustiness seen seem significant?

    A little surprised at how much dust, but then w. MERs dust gets blown off, expecting it to wax and wane. Still some dust on cameras even with dust cover off. Wheels on very firm ground, no sinkage. Soil pretty firm. Might choose to drive somewhere else to find something softer.

    Any issues with vehicle? Did you imagine that vehicle would be in this good a shape this soon?

    Nothing to keep from moving forward, nothing out-of-bounds. Think we all believed it would land successfully, a little concerned we might land in some sort of safemode, might miss a comm pass, might have to sit and worry. Great telecom performance, orbiters performed beautifully.

    Spend eight years thinking about all the things that might go wrong, in the shower, etc. Can't turn that off. Get to point where it hasn't happened but you can't do anything, either, very stressful.
