I think the similar instrument on Curiosity was slightly damaged by flying debris during landing.


I believe it was non operational due to the damage.

I did not know MEDA was stowed inside those covers and had to be deployed.

If the crater floor is covered by ash or other volcanic material, if Perseverence heads up the delta toward the inflowing river bed, would it be able to find any of the original river- or lake-bed shallow enough that its instruments can reach it? I suppose this area is a major destination for the helicopter.


The helicopter is a demonstration mission, it's not flying anywhere to view stuff, it's only doing 3 short demo flights as far as I know.

I was surprized when they showed the EDL videos so quickly considering those were supposed to be tens of thousands of frames. But I assume now that the frames were compressed into video onboard (they mentioned using ffmpeg) and sent back quickly. Now the raw frames will presumably take some time to return, but once we get them we will be able to make beautifully clean videos...


For future missions the EDL video was high priority, just incase anything bad happened to Percy before the info was transmitted.

Is the software switch over currently happening to the surface ops s/w ? It's Sol7 and no images are on the raw site since Sol4.

Does anyone know if the springs on the heat shield are supposed to be captured or not ?

My first attempt at a quick and dirty anaglyph. Most Nav cam shots are only from the left. This was one I found with both left and right. Not sure if they are a perfect match but it gives some sense of the distance of things.


The rise of the slope between Percy and the valley is quite a bit greater than it first appears.

I don't know about the rest of you, but I am really, really impressed by the performance of the Terrain Relative Navigation (TRN) during EDL. If you look at the landing site, you can see all sorts of hazards such as dune fields and boulders that TRN successfully avoided. Congrats to the team; I cannot imagine how challenging the engineering was for this.

I had a different sort of EDL question: does the thickness of Mars' atmosphere vary enough to necessitate course and trajectory corrections just before EDL?


They had a target box they were in 2 days before entry, the thickness does affect how far up range or downrange of the target you go, they do guidance when on the heat shield to hit the target landing spot, ofc we do not know how much deflection TRN did to get to a safe spot, might have been 20 meters, who knows ?, but that ofc is after the time on parachute.

The small cliffs on the delta remind me of Victoria crater's rim.

I think rule 1.3 may need amended as they are looking for fossils...that's the whole point of the mission...

BTW, the documentary "Built for Mars: The Perseverance Rover" on NatGeo last night was excellent. Usually I find these things pretty cringeworthy for a variety of reasons, but this one was great. As someone who has on occasion gotten to be a technician (I torqued several screws on MCZ) it's a nice perspective of what it's like to build flight hardware, not often seen on TV.


Glad you mentioned the show, watching it now, 3 mins in and it's awesome.

I agree that propulsion engineers would like for the rover to visit the sky crane crash site.


Adam said in his slightly drunken (whiskey smile.gif ) Instagram live video that the descent stage was sent by the scientists somewhat surprisingly North ( they had a choice north or south), and he did indeed say they'd love to visit the descent stage.

I thought these tall rocks in the near distance in JRehling's photo were interesting. They seem different from their neighbors and the usual flat white rocks we see most places on Mars. Brought here in outflow from the delta?

They look like mission ending rocks too...

The raw images page is still showing only the first three images sent yesterday. Do we know if that page will be updated as soon as images come down? What is the image policy for this mission?


Normally they are there straight away, but it's pretty obvious right now they are withholding images for the press conferences, which in my opinion is quite disappointing.
