The team studying these sounds found that Mars' thin air, composed mostly of carbon dioxide, makes sound waves behave ...

which supplied enough hydrogen to build up in the atmosphere over millions of years. During the fluctuations between warm and cold climates, the chemistry of Mars' atmosphere was also fluctuating.

On Mars, sunlight breaks apart water molecules in the atmosphere into hydrogen and oxygen atoms. This process, known as photodissociation, releases two types of hydrogen: regular hydrogen and a ...

As on Earth, where average atmospheric pressure clocks in at around 101.3 kilopascals (kPa), areas of Mars experience differing levels of atmospheric pressure. The peak of Olympus Mons (the ...

Molecular hydrogen (H 2), by contrast, did not condense and was transported to the upper atmosphere of Mars, where it was lost to space. This conclusion—that water vapor condensed and was ...
