@65dBnoise If it comes to a fight, my money would be on the tardigrade. Those things are renowned survivors :)

The total traverse km and miles was not provided for 3878 in the JSON or GeoJSON. Those will likely be corrected following the next drive. The total traverse is around 30.24km

Going to be an interesting (rough) ride to that cluster of impact craters :)

Two images of one of Curiosity Rover's wheels acquired 13 months apart. These show that the wheel wear has slowed dramatically.

@auricom

Here's a summary about the changes to the driving algorithm:

https://mars.nasa.gov/news/an-algorithm-helps-protect-mars-curiositys-wheels/

TL:DR The revised traction control algorithm uses real-time data to adjust each wheel's speed, reducing pressure from the rocks. The software measures changes to the suspension system to figure out the contact points of each wheel. Then, it calculates the correct speed to avoid slippage, improving the rover's traction, and preventing damage.

@self They have avoided some of the worst terrain. The Greenheugh Pediment was bad, the terrain there was dubbed "gator-backed". Here's a blog where the geology team talk about avoiding the worst of the terrain but ensuring they reach the science waypoints https://mars.nasa.gov/msl/mission-updates/sol-2032-2033-the-rocks-vs-stone-cold-aluminum-wheels/

The rover recently drove out of Marker Band Valley, they had numerous failed drives due to the difficult terrain, I honestly expected this wheel check to reveal a lot more damage, but it has held up remarkably well.

spotted a piece of debris probably from the , the piece of machinery that put it safely on the Martian ground. Debris has been spotted elsewhere, but this piece may be the farthest yet, about 4.6km away.

The map shows the current location of the rover and the location of the Sky Crane crash.

The map sometimes shows a detailed path for an flight. When that happens, one can see exactly how the responds to changes in the terrain underneath it. Here we also see its hazard avoidance capability in action, choosing the best location just before landing.

It's a pity they don't report the elevation, pitch, roll and yaw at each waypoint, (I'm guessing they have it) As it would be fun to see the ups, downs and twists as well as the lat - long etc :) I realise we can derive some of that from the NavCams (when the shadow is visible) But the actual data would be cool... ? :)

No holiday for Perseverance Rover in Jezero crater

Looks like they're setting up for a little contact science (L-NavCam)

Six Years ago Curiosity Mars Rover checked its wheels. Here's one of the hand-lens images, it just happened to capture the Murray Buttes in the background. The rover is scheduled to have another wheel check soon.

Good job they made those sample tube to a high spec. Could be a delay in picking them up...

I have located the location of Flight 52 which occurred on Sol 776 (April 27, 2023). Communications were lost just before landing for 63 days. These images just came down from that flight after Perseverance drove to a location to receive a signal.

"The 52nd flight of NASA’s Ingenuity Mars Helicopter is now in the official mission logbook as a success. The flight took place back on April 26."

It took 63 days to tell us that the heli flew its 63 days ago. I have no words.

I'm testing a new tool that helps do quick trips back in time and see the future in fresh images of that past sol 🤔 😀. It makes it easy to show future places from what was 'present' at that time, by searching through the whole database of (checks numbers) 484,569 images.

Here is one from April 26 of 2022, showing June 30 of 2023. We were all one year younger back then 🥴.

@65dBnoise @stim3on Is there an 'Idiots Guide to Quaternions' available for old dogs like me :) I saw them in the JSON, but have no idea what they do 🤔

Remember when was the last time we saw ? It was back on Sol 766, when arrived at RMC 38.2208, a few sols before it reached the edge of Belva. At that location the rover came at a distance of about 23m from the and captured a number of images with its NAVCAM and MCZ cameras.

As it happens, one of those NAVCAM images also captured some of the crafts' future locations, where they happen to be right now.

Confused with time travel?
