인사이트야. 내 이름은 ‘지진 조사와 측지학*, 열 이동 등을 이용한 내부 탐사(Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport)’라는 임무의 앞글자를 따서 마스 인사이트(InSight)라 지어졌어. 이전에 화성에 온 선배 탐사선들은 주로 화성에 생명체가 있는지 확인하는 것이 목적이었어. ...
NASA)은 무려 30여 년 전인 1989년 9월 ‘실내 공기 오염 완화를 위한 인테리어 조경 식물(Interior landscape plants for indoor air pollution abatement)’ 보고서를 통해 대나무야자(Chamaedorea seifritzii), 황금죽(Dracaene deremensis) 등 25가지 식물 종이 공기 정화 효과가 있다고 발표했는데요. 우주인의 생활 공간에 25가지 ...
(USA) and the US Department of Energy’s Oak Ridge National Laboratory built a 3D map representing the Earth’s interior 2800 kilometers underground. As variations in the speed of the earthquakes’ elastic waves indicate differences in the composition, density, and temperature of the medium they travel through, scientists could outline several interesting phenomena hidden under our feet ...
70 percent of the world's fresh water, yet its atmosphere is as dry as a desert. And, of course, it is cold - the interior of Antarctica is the coldest place on Earth. But the extreme cold and dryness make it THE place where equipment - and people - can be tested prior to possible scientific expeditions to Mars!Antarctica was discovered on Nov. 16, 1820 by a young American sealer named ...
time it 'outgassed' through volcanoes after the crust of Mars first formed, 3.9 billion years ago.It seems that the interior of Mars was much wetter than had been thought, but not enough to account for the 'torrents' of water that once had to be on the surface to make all those channels. Perhaps comets banged into Mars, depositing water. Or maybe there's more water down under. Nobody knows for ...
seemed to people who were exploiting the field that it was ready to offer cheap smog-free electricity from the Earth's interior. What's more, there seemed to be more and more of such electricity produced. By 1990, it was suggested that 2,000 megawatts of electricity would be produced.Unfortunately, that's not the way it worked out. The amount of electricity being produced is not 2,000 ...
could penetrate a crevice in such a way that only on the morning of the summer solstice, it would illuminate the interior in a particular way.Robbins and Westmoreland have been studying a burial bowl in New Mexico. At its center is the figure of a rabbit, which may well signify the moon, for many Native American tribes imagine that the moon's dark markings represent a rabbit (just as in ...
other possible sources for the iridium, too. A period of vast volcanic activity may have brought up rock from Earth's interior, which is also richer in iridium than the crust is.If, however, a crater can be found, that can only have been caused by a meteorite strike. Nothing else we can imagine would do, and that would settle the matter.Of course, we don't have to actually find the crater ...
Pangaea's climate on a computer and reported on the results this past spring.As might be expected, the climates in the interior would be ferocious. Summer temperatures may have routinely reached a high of 115℉ or even more, and the winters would have been way below zero.If one plots out the portions of Pangaea that would have had temperatures as bad as, or worse than, that of the north ...
worry about because, after all, isn't Antarctica just a huge waste of ice?Actually, though, that isn't all it is. The interior, admittedly, is the most life-free spot on Earth, but the rim of the continent is home to penguins, seals and skua gulls.And more than that, suppose we consider the area around it, the Antarctic Ocean.Life on land depends on water rather than oxygen. Oxygen is freely ...
