Space instrument spurns stepper for brushed dc motor BAMMsat-on-BEXUS is an attempt to create a miniaturised bio-lab compatible with 3U CubeSats, run by academics and students from Cranfield University and the University of Exeter. “Researching the effects of microgravity and radiation in on-ground facilities has technical constraints that can add complexity to data interpretation,” said project head and Cranfield PhD student Aqeel Shamsul. “However, in-flight experiments come with their own challenges, often entailing expensive launch missions. These factors are limiting research into the effects of environmental space factors on biological systems. We’re combatting this by designing a cheaper way to conduct biological research in space.”
