Abstract

Experiments aboard "Spacelab-D1" and "Cosmos-1887" revealed an adverse effect of space flight on Carausius morosus embryos. The main influencing factor for stick insect eggs turned out to be microgravity, while the contribution of HZE particles of cosmic radiation was relatively low. Flight experiments indicated an increased vulnerability of stick insect eggs to microgravity at intermediate stages of development, that could support the "convection" hypothesis.

摘要

在“太空实验室-D1”和“宇宙-1887”上进行的实验揭示了太空飞行对桑氏竹节虫胚胎的不利影响。结果表明，对竹节虫卵产生主要影响的因素是微重力，而宇宙辐射中的高电荷重离子（HZE）粒子的影响相对较小。飞行实验表明，在发育的中间阶段，竹节虫卵对微重力的敏感性增加，这可能支持“对流”假说。
