The transfer orbit to Mars will last for several months and will require reclamation of the oxygen in the carbon dioxide exhaled by the crew.

The methane is stored in a tank under pressure and is available to control the orientation of the spacecraft by controlled venting. A single astronaut exhales 1.09 kg of carbon dioxide each day.

- Problem 4 134. Astronomy About 65 million years ago an aster- oid struck Earth in the area of the Yucatan Peninsula and wiped out the dinosaurs and many other life forms. Judging from the size of the crater and the effects on Earth, the asteroid was about 10 km in diameter (assumed spherical) and probably had a density of 2.0 g/cm³ (typi- cal of asteroids). Its speed was at least 11 km/s. (a) What is the maximum amount of ocean water (originally at 20 °C) that it could have evaporated?
