Watch This Rocket-Powered Manned Centrifuge in Action
Amateur space travel are not words you'd like to hear in the same sentence. But astronaut Peter Madsen is eager to test out a homemade rocket centrifuge that pulls 7 g's, in preparation for a manned rocket launch into the stratosphere.
Madsen describes how upon reaching his bodily limit, he began to lose vision and nearly black out.
Reaching the peak of human endurance is important if the DIY rocket is ever going to get off the ground. The aim is to leave earth in an amateur-built rocket ship by 2019.
