Brochure: The DLR parabolic flights – Research in weightlessness (2009)
Everything on Earth is subject to the force of gravity. The effects of that force vary greatly: Sometimes they are very minor and go unnoticed by man, while at other times their impact is fundamental. In some scientific experiments, gravity may be a disturbing factor. In others, you exactly would like to know what happens without that factor. In these cases, researchers need a weightless environment to conduct their investigations.
