Is there life on Mars(火星)? We do not know. But we are sure that earth people do not live on Mars. Earth people need oxygen to breathe. There is almost no oxygen on Mars. It is uncertain exactly how life arose on Earth, so it is difficult to determine how common such mechanisms ...
according to new observations by NASA-funded scientists. Previous measurements of this tracer—isotopes of oxygen—have disagreed significantly. An accurate measurement of this tracer is important to estimate how much atmosphere Mars once

on Europa, on Ganymede, on Enceladus, on Titan, and now we are finding a geyser and hot springs on Enceladus, Our solar system is turning into a giant spa. For anybody who has gone to a spa knows how much microbes like that, right?
The Earth Is Getting a New Mini-Moon A Hidden Ocean Is Lying Deep Within Mars Crust The Earth May Have Once Had Multiple Moons NASA Finds Evidence of Past Martian Microbial Life This Extreme Moss Could Grow on Mars There are Lava Tubes on the Moon ...
Cost, of course, is another factor. While Curiosity, the most recent rover that's part of NASA's Mars Science Laboratory mission, cost a whopping $2.47 billion to build, NASA still didn't have to account for pesky things like allowing someone to breathe oxygen [source: Space.com]. Or ...
Of course, no one would be able to complete that walk continuously — on Mars, Earth or anywhere. Even if the person were able to bring enough oxygen, water and food with them, and could eat and drink while walking, they would still need to stop to sleep. Assuming the astronaut slept...
Using electrolysis, some of these devices split water into hydrogen and oxygen gas. Then, the former is combined with an undesirable compound: carbon dioxide (CO2). Humans naturally exhale this colorless gas, but breathing in too much of it is hazardous to your health. On Earth that usually ...
At 6:31 p.m., a spark ignited in the lower equipment bay of the spacecraft. The atmosphere inside was 100 percent oxygen. The astronauts didn’t have a chance. The evening before the fire that claimed the lives of these three men, loyal viewers had tuned in for “Tomorrow Is Yesterday...
(Phys.org) —New findings from NASA's Curiosity rover provide clues to how Mars lost its original atmosphere, which scientists believe was much thicker than the one left today.
