The evaporation of sessile drops of various volatile and non-volatile liquids, and their internal flow patterns with or without instabilities have been the subject of many investigations. The current experiment is a preparatory one for a space experiment planned to be installed in the European Drawer Rack 2 (EDR-2) of the International Space Station (ISS), to investigate drop evaporation in weightlessness. In this work, we concentrate on preliminary experimental results for the evaporation of hydrofluoroether (HFE-7100) sessile drops in a sounding rocket that has been performed in the frame of the MASER-14 Sounding Rocket Campaign, providing the science team with the opportunity to test the module and perform the experiment in microgravity for six consecutive minutes. The focus is on the evaporation rate, experimentally observed thermo-capillary instabilities, and the de-pinning process. The experimental results provide evidence for the relationship between thermo-capillary instabilities and the measured critical height of the sessile drop interface. There is also evidence of the effects of microgravity and Earth conditions on the sessile drop evaporation rate, and the shape of the sessile drop interface and its influence on the de-pinning process.

各种挥发性和非挥发性液体的无蒂液滴的蒸发及其内部流动模式（带有或不带有不稳定性）已成为许多研究的主题。当前的实验是一项空间实验的准备工作，该实验计划安装在国际空间站（ISS）的欧洲抽屉架2（EDR-2）中，以研究失重中的液滴蒸发。在这项工作中，我们集中于在MASER-14探空火箭战框架中进行的探空火箭中氢氟醚（HFE-7100）固着液滴蒸发的初步实验结果，为科学团队提供了机会测试模块并在微重力下连续六分钟进行实验。重点是蒸发速率 实验观察到的热毛细管不稳定性和去钉过程。实验结果为热毛细管不稳定性与固着液滴界面的测量临界高度之间的关系提供了证据。也有证据表明，微重力和地球条件对固着液滴蒸发速率，固着液滴界面的形状及其对去钉过程的影响是有影响的。
