“…. &, ps, if you’r trying to fake a landing on a comet, try not making the model so “anthropomorphic”….”
Data from the Rosetta spacecraft says asteroids and not comets are likely to have formed the Earth’s oceans. The probe found the water vapor it’s been studying on Comet 67P is significantly different to that found on our planet. The key part of the discovery is the ‘flavor’ of the water that is found on earth. The vast majority of water molecules on our planet are made up of hydrogen and oxygen atoms. However, very occasionally, they will be replaced by a deuterium atom, which looks like water, but is heavier in mass. Deuterium is a form of hydrogen, but has one more additional neutron. The researchers found that Comet 67P, which is also known as the Churyumov-Garasimenko comet, after the two Russian scientists who discovered it, had levels of deuterium, which were three times greater than that found on Earth.
except that there’s “more than one” (understatementus maximus) comet, so basing such a claim on a few minutes of data from one tiny area of one comet is spurious to say the least, besides, Earth in its early formation days had loads of hydrogen, oxygen & lightning etc, ie, could easily have made its own water before atmospheric hydrogen was lost to space.
The question about the origin of oceans on Earth is one of the most important questions with respect to the formation of our planet and the origin of life. The most popular theory is that water was brought by impacts of comets and asteroids. Data from the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument aboard the European Space Agency’s Rosetta spacecraft indicate that terrestrial water did not come from comets like 67P/Churyumov-Gerasimenko. The findings were published today in the journal Science.
