    This is a supercut of 2 older videos of mine about ESA's Rosetta-Philae mission to 67P/Churyumov-Gerasimenko. This is probably my favourite ever ESA mission, so to do it justice, I have made a lot of improvements to the older episodes. Improvements include:
    4K (where available) and 60fps.
    New narration audio.
    New music where I felt it could be improved.
    A lot of new footage.
    Condensed two scripts into one.
    Added additional information where available.
    You will have to forgive me though, I forgot to add the CGI sticker. Really not ideal and I apologise. But I hope you still enjoy it, I really enjoyed revisiting this one.

      for you:
      The moon carried a large amount of water and instantly submerged Atlantis and Lemuria. It appeared only a few centuries ago, and it is very close to history (some departments tried their best to cover it up). The earth's magnetic pole shifted, and the entire connected continent changed. into five continents.
      By the way, it lowers the frequency of the surface of the earth, and the water on the surface is no longer the same as the center of the earth. 3D-4D-5D to the center of the earth; Shambhala gates are permanently closed
      The outer matter becomes very heavy, the multi-dimensional structure is isolated in an instant, and almost all the etheric matter is evacuated
      The optical coded wire cannot be connected....
      A Hint:Marduk betrayed the Anunnaki and the Serpents took over the Earth;Serpent family includes Orion and Draco and Sirius B group
      Orion controls human beings in 3D and 4D, and almost controls elite groups and religious ; the central council prohibits Draco from entering the earth, Draco cooperates with AI gods to use biochemical humans to invade the earth, want to biochemical humans!

      first: Light a candle in your bedside sleeping place: Silence for 30 seconds and start to meditate:
      May brothers and sisters of light from the divine love quality of source that transcends all time and space and beyond Matrix, I would like to connect with you all the time.
      What you want to do, see, and become, I also want to do, see, and become;

    The ESA was using Microdyne 700 series Telemetry receivers at the time this mission started. We built two earth stations for them, One fixed site, and one mobile. Both were turnkey packages, and they ere built in Ocala, Florida. I tested and cerified the digital boards, along with the video filters and the low phase noise Frequency Synthesizers in the receivers.

      @@toter-drache Telemetry is remote data collection. Microdyne downgraded their early Telemetry design to provide C-band Satellite TV receivers about 40 years ago. A that time, both product lines were their 1100 series. These Cable TV and Broadcast station grade receivers show up on Ebay still working at 40 years old.
      To track a distant satellite, you use multiple receivers with a complex combining system to reduce or eliminate fading. Each has its own dish antenna, and the process is called 'Diversity Reception'. This process was developed during WWII to help monitor enemy shortwave radio signals. Typically tree radios and their separate antennas.

    So, the thing is, heavy water is slightly less volatile than regular water. Since inner solar system comets have been outgassing for billions of years as they get closer to the sun, the level of deuterium/hydrogen would increase as shown in the graph. Back when earth was seeded, most likely the ratio of D2O to H2O was similar to what it is on earth now. We would need to venture out to the Oort Cloud comets to confirm this

    I realize that this is a report on the Rosetta-Phylae mission, but while I also learned that comets are ice balls it's not necessarily only water ice (which we were not told because at the time I was in college/graduate school it probably wasn't known) and I would find it far more interesting what else than water was detected outgassing, like methane, which appears to be common, and more extremely, acetylene in Hyakutake and such things. I remember showing my daughter Hale-Bopp, and Hyakutake reaching across half the sky here in Hawaii.
