I thought the deployment would have been so much slower with stops at many locations to check things, looks like it was one smooth deployment movement. |

I never was able to get Cargo Cult's walkabout VR version of InSight's landing site working, just brings up a simple image, perhaps i need SteamVR equipment or something like that? Yes you need VR equipment. |

The grapple is designed to grab, so it's impossible to lose grip. To open they use a wax actuator. https://www.nextgov.com/emerging-tech/2018/...-lander/152070/ |

New pics down, lowering grapple to the seismometer, my question is are they ready to deploy it ? |

Just a new thought here. Most of us have heard the "sound" of winds moving around insights solar panels audio recorded by the seismometer I think. Could these vibrations transfer to the ground and hinder the supper sensitive seismometers work? They said it was unlikely, that's why they want it on the ground, also they would be able to characterise the noise of the vehicle and be able to ignore or recognise it during the long silent listening phase, if it did indeed transfer. |

...Obviously just a press release, so take it with a grain of salt, but a NASA/ESA partnership seems like the best way to split the costs. ... I have never heard any talk of splitting costs from NASA HQ staff, eg the reason Insight has the instruments it has are because they were the best available to achieve the mission objectives, not to split any costs. |

Regardless of all the data from orbiters there is a degree of luck involved in landing. Curiosity did a hole in one in a small crater. Imagine if she had bounced to a stop in the middle of Endurance crater's central dune field. Always a chance of that 1 or 2 % end of mission landing... |

Moment of well-meaning pedantry here: Weight and mass have been mentioned several times and there's that factor of 2.64 difference between Earth and Mars, as well as the distinction between weight (in, eg, Newtons) and mass (kg). For any given object, its mass, weight on Earth, and weight on Mars are three different numbers. I'm not sure that anyone has made any mistakes in the posts above, but there's a lot of potential confusion here. As it is, the Insight lander is heavier than Phoenix, using the same landing jets, maybe Propguy can inform us how much more margin is in the lander for future heavier missions ? |

Of course. "... InSight's robotic arm also has a bucket with a capacity of roughly 500 g of soil. However, this bucket is not intended for massive excavation works; its main role is to prepare the ground as well as possible before setting the instruments down. It allows engineers to shift a stone that is in the way, flatten a little mound in an otherwise optimal deployment sector, or simply check the nature of the ground." https://www.seis-insight.eu/en/public-2/the...ida-robotic-arm I was wondering why they even had a bucket, ty for that. |

Does anyone know if they have an official mission clock for InSight? Similar to the one we have for Curiosity link that shows the sol and current solar time. https://mars.nasa.gov/insight/ |

Just a quick thought about the Insight payload. If the spacecraft did indeed land on a sand sheet or filled crater, it might be a problem for the seismometer. Any thickness of sand would, if I understand seismometers correctly, cause seismic signals to be dissipated before they reach the instrument. Sand, being much less compacted than rock, would not conduct a seismic signal nearly as well. Even soil should conduct better. I would love to be proven wrong. Alternate opinions welcomed. It's super sensitive, it can detect half the movement made by the vibration of a hydrogen atom. If something bangs into Mars, it'll detect it. |

... First, I'm still scratching my head at the torturously slow (three month) deployment of the two surface experiments... Well in reality they are going to be deploying the instruments 2 or 3 times in the sandbox here on Earth, before they do it with Insight on Mars, so that takes time. |

... The flat sandy terrain visible by the landing leg seems to finish abruptly a few tens of meters off, at rougher boulder terrain, from the higher viewpoint looking out alongside the seismometer cover... To my eyes it looks like sandy spots interspersed with rocky spots. A billion years of wind and no rain can do strange things... And I still don't think it was the parking lot they expected. |

In the early stages of the mission, can InSight's seismometer be used in concert with the hammer that is to drive the thermal mole into the ground, as a sort of sonar device to help locate buried rocks and maybe identify the best path to get the mole all the way to its desired 5 meter depth? Moved. -Admin. There was no mention of that. The PI did say small rocks would be pushed aside by the Mole, but if it hit a big flat rock then that was as far as they could go, it won't go upwards. It's all about risk. |
