Lethal radiation, low vacuum pressure and low temperatures - this is how space welcomes organisms. Crossing of immense interstellar distances inflates the exposure time of biological material to harmful space conditions. This paper discusses the intriguing possibility of a life-bearing exoplanet being ejected from its planetary system and carrying life across interstellar distances (nomadic = free floating = rogue planet). The proposed interstellar panspermia mechanism reduces the exposure time to space conditions and provides multiple chances for interactions between microbes-bearing rock debris and exoplanets within system the nomadic object encountered on its way. The testing strategy is outlined and discussed in the paper, including testable predictions the proposed hypothesis makes.

关于星际生命转移槽游牧物体的假想机制。

致命的辐射，低真空压力和低温-这就是空间欢迎生物的方式。跨越巨大的星际距离会使生物材料暴露于有害空间条件的时间变长。本文讨论了一个有生命的系外行星从其行星系统中射出并在星际距离内携带生命的奇妙可能性（游牧=自由漂浮=流氓行星）。拟议的星际泛精子机制减少了空间条件下的暴露时间，并为携带微生物的岩石碎片和系外行星之间的游牧物体在其途中遇到的相互作用提供了多种机会。本文概述并讨论了测试策略，包括提出的假设所做出的可测试的预测。
