I thought the Curiosity rover had a effective zoom lens option.


The zoom cameras were unable to be used due to time for testing and budget reasons, so the original fixed focus cameras were used.
The Mastcam 100 does show far objects in good detail.

Also to the general public it will look exactly the same...

The main point is though Sandra has nice legs, apparently. Also it's a movie, not a space documentary.

I believe they hope to fly past maybe two KBO's.

I'm struggling to understand how colliding with a rock at a speed of a few centimetres per second could have been "mission catastrophic". (Just as well my car is more robust.)


Remember Oppy does not travel very fast but she has tons of torque, so she could crunch herself pretty bad.

So about 1/6 of the way there. A fast pace indeed.

A very draft of the Sol 376 drive as seen by Front Hazcam Left B:


I am slightly surprised how much the wheels were steering left and right. You'd think it would just plough pretty much straight ahead.

There seem to be two different camps among the Curiosity science team as to the benefits of imaging EDL hardware.


Well one thing is known for sure, the EDL hardware worked pretty well this time smile.gif.

The rover is VERY dusty, changing color.


Dust fall never ends on Mars does it......
Also is of note, some of the smaller pebbles have disappeared, blown or fallen off the rover deck ?

P.S. If scientific justification is needed for the side trip, it could be written up as " brief stop at EDL Hardware location to study dust accumulation rates within a known time frame".


They can just image the rover deck to do that.

But why they cannot plan for at least every second sol is a bit puzzling for me.


Remember, MSL is on battery power, the batteries are recharged by the MMRTG, so you can't operate anyway 24/7 with fully charged batteries. Also no driving during the Mars nighttime which of course could be Earths day time, depending on the synchronization of both planets. So sometimes it's "2 days" between drives, e.g.
Also they have a budget to adhere to ( so they can't just have a whole spare team ready to occasionally take over ), and are in this for the long term.

I think I may have equated 'margin' with 'over engineering'.
I still think though the team was staying with the 90/180 day thing, as the costs for a 10 year mission would not have been at the time favorably looked at by the beancounters...... wink.gif. There was even conjecture at one time one rover would be turned off to save said beans wacko.gif.

..compared to design requirements....


JPL engineers admitted the MER's were overengineered and that the 90 day mission time was very likely to be exceeded, barring some unforseen problem. So comparing to the 90 day required time is not really a valid reference point. The main reason Sprit died was it got trapped in sand and could not tilt it's solar panels to the Sun. That of course could have happend on the first drive if fate had meant that to happen.

I'm not following your reasoning; the entire tire is one piece of aluminum, beefed up where the flexures attach.

Maybe the slide I referenced will be useful.


Actually you referenced slide 32, and it's slide 31, that threw me a bit, lol. smile.gif

It does not scan, it stares to see changes, you can't stare with only 2 wheels.

We've always talked about ground software and flight software. It's descriptive and unambiguous. It's hard to think of alternatives that would be better.

It's also the same software that was flying the spacecraft on the way to Mars and during EDL.


Correct me if I am wrong but the same software is not used for ground ops as was used for EDL, thats why they changed the software after landing.

They did say they are no where near having ran all the scripts they can on Sam and Chemin, so new findings should be expected as time goes by and they gain more experience with the equipment in situ.
