Great video, and superb obligatory comic. laugh.gif

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.

There is a supplementary file here (a c. 18 MB TIF file):

which I think is open access (correct me if I'm wrong), and this gives the names of the nearly 200 quadrangles used for mapping the site. I really wanted to have this for Curiosity, but it was never released, as far as I know.


Phil, wonderful stuff - does the paper provide a scale for this map, specifically the size of each of these quadrangles, also it would be good to know how to attribute it smile.gif (I dont have access to the paper)
TIA

Hi Paul - this abstract from LPSC earlier this year:

https://www.hou.usra.edu/meetings/lpsc2020/pdf/2254.pdf

says the quadrangles are 1200 m by 1200 m.

This is the paper citation:


Stack, K.M., Williams, N.R., Calef, F., Sun, V.Z., Williford, K.H., Farley, K.A., Eide, S., Flannery, D., Hughes, C., Jacob, S.R. and Kah, L.C., 2020. Photogeologic map of the perseverance rover field site in Jezero Crater constructed by the Mars 2020 Science Team. Space Science Reviews, 216(8), pp.1-47.

Hi all,

Before February 18th I will be trying to get an article about Perseverance into one of the major newspapers of Denmark. I had an article in "Politiken" about the SpaceX Starship just before its December flight test.

Would you know of a good resource with a timeline of all EDL events? - I have been struggling a bit to find a source for all events with the precise Earth time as well as the expected altitude and speed at the time of the event. I'm sure the data is out there, but would like it from an authoritative source.

Thanks!

The EDL timeline is not precisely known in advance but can vary by as much as a minute or two at least.

https://mars.nasa.gov/mars2020/timeline/lan...escent-landing/ is as good as we know. Predicted landing time is Feb. 18, 2021, at approximately 12:30 p.m. PST (that's 20:30 UT.)
