作为这趟可能去到火星旅行的部分准备，六个宇航员最近在莫斯科的一个无窗密封舱里呆了500天。

As part of the preparations for a possible trip to the Red Planet six astronauts recently completed a 500-day stay in a windowless capsule in Moscow.

在飞行第一阶段，助推器将于密封舱分离，之后在重新进入地球大气层之前，密封舱将会进入一段无重力的抛物曲线。

During the first phase of the flight, the booster will separate from the capsule, after which the capsule will travel through a zero-g parabola, before re-entering the earth's atmosphere.

多备一份必需品，诸如发型设计产品、羊绒垫子、棉签等等。 使用短的密封袋，平时装无萝卜的那种。

Buy duplicates—preferably miniatures—of all your necessities: hair styling product, cotton pads, QTips, etc. Use the short Ziplocs (the ones that hold carrot sticks)
