The present status of research on the composition of planetary atmospheres is reviewed. It is shown that CO 2 is the major constituent in the atmospheres of Venus and Mars, and that H 2 is almost certainly the dominant constituent for the outer planets Jupiter, Saturn, Uranus, and Neptune. ...
Mars atmosphere composition According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less Earth's. Humans therefore cannot breathe Martian air. For crewe...

Although we do not know the precise composition of the early atmosphere, there has been enough progress made on this subject in recent years that it is possible to say with some certainty that the methane-rich composition envisioned by Oparin, and the methane-ammonia-hydrogen mixture used by Mi...
: given the cool temperatures and the composition of nearly 90% hydrogen, the atmosphere should be colorless. One hypothesis suggests that perhaps colorful hydrogen compounds rise from warm areas. The actual colors are a bit more muted, as shown inFigure 1 in Exploring the Outer Planets....
The Origin of Earth’s Atmosphere Paragraph 1:In order to understand the origin of Earth's atmosphere, we must go back to the earliest days of the solar system, before the planets themselves were formed from a disk of rocky material spinning around the young Sun. This material gradually coal...

The basic principle is that the surface temperature and pressure of a planet should allow for liquid water. This is determined by the amount of irradiation that the planet receives from the star, and the response of the planet's atmosphere. The latter delicately depends on the composition of ...
