Congratulations to the InSight team on a successful landing! We'll discuss the remainder of the mission here.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I found a very detailed summary of deployment procedure/timeline here: https://www.nasaspaceflight.com/2018/11/ins...cience-mission/

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. |
