new audio teleconference in a couple of min
from the visuals posted: first wheel, arm movements, neutron instrument, meteo package


Wow, it's real windy, 25 m/s.

What about 8% air humidity, is a lot! (or I misunderstood...) blink.gif

Damaged wires on two wind sensor circuit boards...

Can't Mahli look at the mast? Maybe see exactly what happened?

dilo, that graphic is a place holder for the actual weather site.

That stinks. This will probably make wind direction determination challenging.

Wind speed is given as an example. 25 m s-1 is not a real measurement. The clue was probably the 8% humidity... tongue.gif

The air pressure curves that show distinct repeatable notches in the cooling phase each day are apparently 'similar to predicated models'. Anyone have a source for those?

As far as the damaged wind transducer goes, it sounds like they have a fully-functioning backup on the other boom. So they might have to schedule in multiple readings each day with different mast rotations to nail down the direction, but will still be able to get accurate readings.

With the latest navcam images:

...it looks like the wheels have turned, no?

EDIT; Sorry, behind the curve--just noticed in the teleconference visuals that they talked about this today.

REMS is on the part of the mast that doesn't rotate (below the azimuth actuator.) So this isn't possible.

The rover could rotate though smile.gif.

And burn 600 Whrs just to heat up the mobility actuators to do so? Non starter.

They clearly said, repeatedly, in the press conference that this will just degrade the wind measurements. Not eliminate them or break them, just degredation when the functioning mast is in the wind 'shadow' of the mast.

Anyone know how fast they will have the recording of today's telconference online (I was on the road and couldn't listen in real time)? I've seen the briefing slides at: JPL MSL Teleconference Materials
