(登陸火星)進行了更多探險。
Huge solar mirrors are put in orbit round Mars to heat the polar ice caps.
巨大的太陽反射鏡被射入火星的軌道來給兩級冰冠熱量。
The ice caps are sprayed black, so that they do not reflect the heat away.
冰冠呈黑色霧狀,這樣就不會將熱量反射掉。
Chemicals are released into the air.
化學物質(zhì)釋放到空氣中。
As a result, the atmosphere becomes thicker and retains more of the Sun's heat.
結(jié)果,空氣變得越來越厚,保留了更多的太陽熱量。
If the greenhouse effect can be started, the ice caps will melt, releasing water vapour, and the temperature will rise to -40℃.
如果溫室效應(yīng)能夠發(fā)生,冰冠就會融化,同時釋放出水蒸氣,溫度將升高到零下40攝氏度。
Stage 3 (AD 2095-2130)
第三階段(公元2095年-2130年)
Next, plants are introduced from Earth.
接下來,植物從地球中被引進。
If these plants can survive on Mars, carbon dioxide can be converted into oxygen.
如果這些植物能在火星上存活,二氧化碳就可以被轉(zhuǎn)化為氧氣。
The first clouds appear, and the sky slowly turns from pink to blue.
第一片云出現(xiàn)了,天空慢慢由粉紅色變成藍色。
The temperature goes up to -15℃.
氣溫上升到零下15攝氏度。
Stage 4 (AD 2130-2145)
第四階段(公元2130年-2145年)
The warming continues, melting more ice. Rivers and small oceans are made.
溫度繼續(xù)上升,融化更多的冰。形成了很多河流和小海洋。
More people migrate from Earth and construct towns.
更多的人從地球上移居來此,建設(shè)城鎮(zhèn)。
Forests of trees are planted.
人們種植很多樹木。
Mars is looking greener. The temperature is 0℃.
火星看起來越來越綠。溫度是零度。
Stage 5 (AD 2145-2185)
第五階段(公元2145年-2185年)
Mars is getting more like Earth.
火星變得越來越像地球。
The amount of oxygen in the air rises, and the air becomes breathable.
空氣中的氧氣含量上升,空氣隨之變得可以呼吸。
The inhabitants can go outside without spacesuits.
居住者能夠不穿太空服去外面。
The temperature reaches 10℃.
溫度達到10攝氏度。
(Since Mars is 228 million kilometres from the Sun, it can never be as warm as Earth.)
(因為火星距離太陽2億2千8百萬公里,它就永遠不可能和地球一樣溫暖。)
Cities, farms and industries are built all over Mars. The transformation is complete.
城市,農(nóng)場和工廠在火星各個地方聳立而起。改造完成了。
