在掌握宇宙空间的特别重要的阶段上突破了极端的困难,我们的人造卫星在历史上破天荒第一次潜入星际空间,并围绕地球而运转。紧跟着与宇宙间可以经常保持无线电联系的第一颗人造卫星之后,在天空中又出现了第二颗卫星。第二颗卫星的规模显然大于第一颗,其中装着供研究用的各种仪器,甚而还有活的旅客——狗“莱依卡”。这是为了检验有关许多宇宙空间因素对生物影响的一系列学说和研究对于损伤性或毁灭性因素进行防御的保护措施。在这实验中即将获得的资料对于将来人们到月亮、火星和金星上去
It has overcome extreme difficulties in the particularly important stage of mastering cosmic space. For the first time in our history, the artificial satellite sneaked into interstellar space and circled around the earth. Immediately following the first satellite that is constantly radio-enabled in the universe, a second satellite appeared in the sky. The second satellite is clearly larger than the first one, with a variety of instruments for research, and even live travelers, the dog “Lycra”. This is to test a series of doctrines on the biological effects of many cosmological factors and to examine the protective measures against defensive or destructive factors. The information to be obtained in this experiment is for future generations to go to the moon, Mars and Venus
