Jeff Bezos' aerospace firm Blue Origin marked a historic milestone on Saturday (December 20) after launching the first wheelchair user, Michaela Benthaus, above the Kármán line - the internationally recognized boundary of space. German aerospace engineer Michaela Benthaus, an engineer with the European Space Agency, sustained a spinal cord injury after a mountain biking accident in 2018 and has since become an advocate for accessible space travel. #blueorigin #woman #space #aerospace
