Che fine ha fatto l'atmosfera di Marte?
L'atmosfera di Marte, a causa della bassa gravità del pianeta, è estremamente rarefatta e completamente priva dei gas più leggeri; la pressione rilevata dalle sonde automatiche inviate sul pianeta è di circa 0,7–0,9 kPa nelle depressioni più profonde (la pressione media dell'atmosfera terrestre, a titolo di paragone, è ...

What was the temperature on Mars in the past?
- However, chemical analysis of Martian meteorite samples suggests that the ambient near-surface temperature of Mars has most likely been below 0 °C (32 °F) for the last four billion years. Some scientists maintain that the great mass of the Tharsis volcanoes has had a major influence on Mars' climate.
How cold does it get on Mars at night?
- In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).
What are the characteristics of the Martian atmosphere?
- Martian Atmosphere. Surface pressure: 6.36 mb at mean radius (variable from 4.0 to 8.7 mb depending on season) [6.9 mb to 9 mb (Viking 1 Lander site)] Surface density: ~0.020 kg/m 3 Scale height: 11.1 km Total mass of atmosphere: ~2.5 x 10 16 kg Average temperature: ~210 K (-63 C) Diurnal temperature range: 1 K (-89 to -31 C)...
Where is curcuriosity measuring the weather on Mars?
- Curiosity is taking daily weather measurements at Gale Crater in the southern hemisphere of Mars, near the equator. At this location, it's currently early winter.
