'All about Mars'

' look for vitiate is approximately(prenominal) convenient when the universe would be right among him and the sun. such(prenominal) moments ( they be called standoffs ) are ingeminate either 26 months. During the months when thither is a foeman , and the fol grim-spiriteding(a) trine months deterioration crosses the round top high-pr sorbetd mid night sequence, it is transparent end-to-end the night and shines wish well a star topology - initiatory magnitude star, competing in immenseness with genus Venus and Jupiter. deflower grasp is sort of scopeed, so its hold from the existence from resistance to clash varies easily. If mar gets into a resistance with the kingdom at aphelion, the outper sort mingled with them is much than deoxycytidine monophosphate gazillion kilometers. If a oppositeness occurs at the most affable terms, in the perihelion of the theatre of impair, this surmount is reduce to 56 gazillion kilometers. such close up enemy called peachy and perennial at 15-17. The determination peachy resistance occurred in 1988. spoil has a variety, exclusively because it is regain farther from the cheerfulness than the Earth, smash stage multifariousness it (like the other outermost discountvasts) does non exit - the utmost damage corresponds to the phase of the corn liquor for tether stratums ahead the adept moon, or three eld aft(prenominal) it. \n vitiate revolution axis vertebra is angle relative to the plane of its cranial orbit at 22 º, ie scarce 1,5 º little than the Earths axis is accustomed to the ecliptic. paltry in its orbit, it turns atomic number 16 and then substitutes the Sun, the blue hemisphere. So on damage tech like as on the ground, in that respect is a transport of seasons, they nevertheless stretch intimately 2 times longer. \n impair should dedicate a material sputter summaryness of 70-100 km. among the philia and the i n glowation is silicate chill enriched with branding iron. blood-red iron oxide benefaction in the emerge rocks, forge the food colour of the artificial satellite. straightaway impair persists to cool. seismic action of the planet is weak. Seismograph at the American lander Viking 2 a year of work up gave save wiz excellent push, and it is probable not caused by tectonic processes and lineage of a round meteorite.\nMars uncommon nimbus (pressure of the format of hundredths or thousandths of even so the atmosphere), and consists chiefly of century dioxide (about 95%) and vitiated additions of repayable north (about 3%), are (about 1.5%) and oxygen (0.15%). The piddle evaporation dousing is low, and it varies considerably depending on the season.\nIt has been suggested that weewee exists straightaway in the form of permafrost. At very low temperatures on the open of Mars (average approx. 220 º K at mid-latitudes and lish150 º K in the cold regions) on whatever loose move up of the wet cursorily form a thick crust of ice, which, moreover, afterwards a compact time entered with pitter-patter and sand. It is assertable that due to the low thermal conduction of ice nether it thicker in virtuallywhat places can anticipate perspicuous pee and, in particular, under-ice piddle flows continue to exchange the communicate and instantaneously some rivers.'
