  1. Deep sea, they pump mud into the drill pipe sleeve to push out the rock and other material they don't want.
  2. Oh I get that. Let me invite you to look at this: The topography of Jezero crater – landing site of NASA's Mars 2020 mission - DLR Portal - the 'false color' image of Jezero. Specifically, focus on the Neretva Vallis. The Neretva Vallis, in this picture, is the riverbed like structure to the far left of the image. The delta sediments in the crater which everyone is interested in flowed into the lake from here. If you look to the terrain on any side of the smooth bottom of the creek / river / glacier bed, you will see significant cratering. Cratering that does not exist on the b
  3. Physics is fascinating - partly because the specificity of meanings used defy the common understanding of the use of the same words. I wonder if it is the same with German. Are, perhaps, Einstein's ideas better expressed in German? Certainly, the maths are universal (you have to learn that language to converse in it)... but my Internetting without the language of maths tends to leave me with a remarkably incomplete understanding. Again - thanks for 'splaining.
  4. Your post reminds me of a lecture that I had on black body emissions, God, 30 years ago. Okay - so all the breaks shift together? That would certainly discount what I was thinking.
  5. Moving this discussion over here from me getting jiggy with the wrong thread: Question is, effectively, why they chose this location rather than the canyons to the west of where Viking 1 landed. Those channels to the west of Viking 1 look like a long-term water feature, and one that would have originated from precipitation at the nearby high elevations... seems to me that if we are looking for evidence of wet Mars / life... a long established watershed feature might be better than what looks like an impact-driven melt/flow that occurred after Mars lost most
  6. @K^2Thanks for the explanation! Okay - I think I understand my confusion. I was trying analogize 'background' to a visual background rather than 'background noise'. Background noise makes sense - especially given how Penzias and Wilson discovered it. So the CMB photons are everywhere - and, effectively, always have been. On to the thing I'm curious about: Given the vast distances, and that the greater the distance the higher the chances of admittedly rare photon-photon scattering... Is it possible that our current measure of the redshift of distant galaxie
  7. So - I spent some time looking at the Isidis Basin - and there's a lot to be excited about by that site. I'm wondering, however (having scanned around a bit) why something in the Chryse Planitia wasn't chosen. The Kasei channels look like they had much greater (and probably earlier) hydro features. Kasei Valles topolabled - Chryse Planitia - Wikipedia Anyone know if there are any planned missions going here?
  8. Not on that map... and why is Tian? It has not left orbit. Edit - sorry - it's the spot listed as Mars 2020, right? Another site shows it being between Opportunity and Viking 2. Edit, again: yes... it is in the Isidis basin - what is listed as Planitia on this map. Still - why are there Chinese landers there; I thought the currently orbiting mission was China's first. Am I wrong about that? Being in the blue-green makes sense if you are searching for a shoreline. This map really gives an idea of where the oceans might have been. Mons is the white circle al
  9. This info about the CMB being as close to a rest frame as possible is intriguing. I had seen papers describe the apparent temperature differences - but not described as us moving in relation to it. If we have calculated that the sun, and presumably our galaxy is moving at such high speed relative to the CMB, have we also made measurements of say Andromeda or any other galaxy's speed / direction relative to it? Also - if it is merely left over heat... does it permeate the visible universe (like a fog or like heat in an oven), or is it properly described as existing beyond the
  10. Offhand - do you have an idea of where Perseverance is on the map provided? I also presume that this is analogous to, if not in fact, a terrain altitude map?
  11. Remember folks: after a nuclear war, you too can sue! Message brought to you by Dewey Screwem & Howe, PLLC, Attorneys at Law.
  12. According to the wiki on Two-Photon Physics, 'In pure vacuum, some weak scattering of light by light exists' So what would this look like? How would it affect our perception of a distant light source? (was surprised to read this - as I thought light generally passed other light unperturbed)
