Several MSL team members put a paper together for IEEE Big Sky this year - and I just asked the JPL Library to put it out on the JPL Tech Report server. It details the transition to remote ops and how things have changed. Commanding Curiosity from the couch: MSL remote operations, challenges, and path ahead |

Yeah - the landing ellipse is almost certainly larger than that entire image. |

4 NCAM subframes each at 2x2 downsampled. I suspect this is the res we will see most of the time for drive direction Navcam images. |

pyro involved. Looking at the CAD file posted to https://rps.nasa.gov/3D-viewer/ it looks like there's definitely some involved in the chopper - shield deploy for sure, and at least some others around the interface to the rover. |

I would imagine they have taken video of each phase of the deployment which would be show smooth rotation of the various components. There are pyrotechnic devices being fired during these steps. You don't want science cameras pointed at pyro devices when they're going off. |

3 frame twilight cloud movie from Sol 3072 over about 15 minutes. It's fair to say ML and I have been having some fun while the twilight cloudy season lasts. raw frames here : https://mars.nasa.gov/msl/multimedia/raw-im...Asample_type%2C |

There has been no use of autonav so far. There wont be until after the helecopter is deployed. All there has been so far is 'blind' drives. There is little to cause one of those to fault out in terrain like this. |

i use Gmic's built in program " bayer2rgb" I must admit - I've found Gmic's debayer performance to be pretty ugly - especially at the edge of images. I've been using PIPP which can batch debayer images and I've been very pleased with the results https://sites.google.com/site/astropipp/ |

If it bounced it would be visible separately from the impact ‘splat’ in the crime scene HiRISE image.....which it isn’t.. I think you’re seeing the dust cloud of impact and its shadow move with the wind. These are 1hz images, so it’s actually pretty slow. |

All of them came down - including a view of the Heatshield impact. Here's a page of just the LCAM pics, from Ryan's awesome raw browsing interface https://rkinnett.github.io/roverpics/?mars2...&filter=ELM (Congrats Mike C - great work from the La Jolla team) |

The MEDA SkyCam is a repurposed MER/MSL heritage Hazcam. They are INCREDIBLY optically dark. We're tried ( and failed ) to image night time features with MSL NavCams - even Earth and Venus were not visible. You're not going to get much, if anything, astronomical, through the MEDA SkyCam |

Not sure about the morphing of Perseverance to Percy. Then call it Perseverance. Problem solved. FWIW - The name ‘Percy’ was adopted by almost everyone I know on the project pretty much immediately after it was announced. You’re gonna HATE what everyone calls the Helicopter.....so you should probably start getting used to Ginny now. |

Too bad the cliff itself got cut off. It didn't. https://mars.nasa.gov/resources/25676/n_r00...tolm2/?site=msl Jan only uses Navcam left for his mosaics- and much of the time any upper-tier imaging we do is right eye only. It's why I had the script that generates the mosaics that go to https://mars.nasa.gov/msl/multimedia/mosaics swap from left eye to right eye - to catch upper tiers when we take them. Some are taken in stereo - but more often than not - right eye only (Mono imaging has to be right eye as that camera's electronics box is monitored for temperature by the flight software for heating. Stereo imaging has to be within a window when heating isn't required anyway ) |

The front hazcams have quite a significant toe-out between them. ~20deg. page 17 See https://www.ncbi.nlm.nih.gov/pmc/articles/P...Article_765.pdf |

Wow. You have to debayer and then stitch all 16 subframes.....but this is full resolution EECAM FHAZ and RHAZ images. |
