任务简介
上升2号任务搭载上升3KD飞船将两名宇航员帕维尔·别利亚耶夫和阿列克谢·列昂诺夫送入轨道。飞船配备了一个可充气气闸舱，以进行首次太空行走。阿列克谢·列昂诺夫通过12分钟的太空行走成为第一个实现这一壮举的人。任务持续了1天2小时2分17秒，共绕地球17圈。任务中出现了许多问题，例如在太空行走期间，他的宇航服膨胀到僵硬的程度。为了重新活动四肢并返回气闸舱，他不得不释放部分宇航服压力。返回舱后，机组人员在密封舱门时遇到困难；再入期间，轨道舱未能与着陆舱正确分离，导致飞船剧烈旋转，直到约100公里高度处湍流使它们分离；自动着陆系统失效，机组人员不得不依赖手动备份。早期问题导致飞船在卡马河上游高地的森林中着陆，偏离目标着陆区386公里。

Voskhod 2 carrying Voskhod 3KD spacecraft carried two cosmonauts, Pavel Belyayev & Alexey Leonov, to orbit. The craft was equipped with an inflatable airlock in order to conduct the first ever spacewalk. Alexey Leonov became the first person to do so by performing a 12 minute spacewalk. The mission lasted 1 day, 2 hours, 2 minutes & 17 seconds completing a total of 17 orbits around Earth. The mission had many issues, for example during his spacewalk his spacesuit ballooned up to a point where his suit became stiff. In order to move his limbs again and re-enter the airlock he had to bleed off some of the suit's pressure. After re-entering the capsule,the crew had trouble sealing the hatch, during re-entry the orbital module did not properly disconnect from the landing module causing the spacecraft to spin wildly until turbulence caused them to separate at around 100 km and the automatic landing system failed and the crew had to rely on the manual backup. Earlier troubles meant that spacecraft landed 386 km away from their targeted landing zome in the forests of Upper Kama Upland.
