Looks like the rotor blades are now unlocked. |

Some thumbnails came down showing a rotor blade movement. |

A stone seems to be stuck onto the wheel, casting quite a shadow. I wonder if it penetrated the wheel skin ? |

Nothing exposed is pristine after a dynamic landing on dusty Mars... |

They said Ingenuity is a tech demo so they pretty much could use what they wanted, long term survivability was not an objective, so hence the capability of using a modern processor. Also Ingenuity's nav cam takes 30 frames per second pictures for flying navigation purposes. I think they said they did do a little hardening of the CPU, but not the amount a processor would get designed to last a decade or more on Mars. |

They opened a cover on the sample receiving part on the rover, does this cover remain permanently open ? |

Here's my rough and ready mosaic of the 8 overlapping frames of the Sol 22 ejected Belly Pan that protected the sampling system bay during the later part of EDL. De-Bayer (GIMP) stitched (MS-ICE) I did not know there was a cover on the sample handling system, no one ever mentioned that in any of the briefings I saw. |

Do we have any insight as to why the small deltaic remnants exist at such a distance from the main delta front? Did they move somehow from where they were emplaced? What could cause the significant and remarkably complete (scoured clean down to the top of the underlying unit) erosion of the delta material and what saved these remnants which are presumably analogues of the main delta. Could they have been islands in the lake? Likely chance and the vagaries of the wind over billions of years. |

Not sure about the morphing of Perseverance to Percy. For me the rovers, like ships, have all been female and Perseverance's role is a gatherer, traditionally a female role. It was Adam Steltzner himself who referred to her as Percy. "The name Percy is a girl's name of French origin." |

“But perhaps the most visible change is in the grousers. They are ten percent taller and run across the width of the wheel in a near straight line. It’s got a slight curvature to it to help give some strength to it,” says JPL engineer Patrick DeGrosse. That Percy wheel looks pretty good for doing 60Km. |

Been wondering about that too. To make them stronger than straight lines would? Curiosity's were more like the design in most tires, but then inverted; raised rims instead of grooves. I found the answer : "Extensive testing in the Mars Yard at NASA's Jet Propulsion Laboratory, which built the rover and manages operations, has shown these treads better withstand the pressure from sharp rocks and grip just as well or better than Curiosity's when driving on sand." https://www.nasa.gov/feature/nasas-persever...-and-air-brakes |

Why did they make the tread pattern curved and not just a straight line ? |

Hi Steve. They just had a press conference and image release on the mission website which includes this: They will decide soon which of the two paths to take, but they seemed to prefer the clockwise path out of the landing area. Later it meets up with the nominal path through the delta. Phil They could have used different colours for the first part, I thought the blue and purple were the same colour when I watched the news briefing. |
