First Wheelchair User in Space: Benthaus’ Historic Blue Origin Flight
The milestone in human space travel occurred on December 20, 2025, as Michaela “Michi” Benthaus, a 33-year-old German aerospace engineer with the European Space Agency, became the first wheelchair user to travel past the Kármán line. It was more than just a fulfillment of her lifetime passion as she traveled in the Blue Origin’s New Shepard NS-37 spacecraft, as it showed how engineering can make the final frontier more accessible to a wider range of humanity.
1. A Journey Years in the Making
Benthaus’s journey to space was brought about by her resilience. Seven years ago, she suffered an accident while mountain biking that resulted in her having a spinal cord injury and paraplegia. Rather than becoming an obstacle for aspiring astronauts, this accident was seen as an end to any hope of becoming an astronaut by some people. However, Benthaus pushed through and continued her work in mechatronics and space engineering. Her chance came when she sent Hans Koenigsmann, an ex-executive at SpaceX, an invitation through Linkedln on how people with disabilities can also be astronauts. He agreed and even flew along as her crewmate and emergency helper.
2. Engineering the New Shepard for Accessibility
The Blue Origin flight NS-37 did not require any modifications to the spacecraft but added some accommodations on the ground and in the capsule for Benthaus’ safety and convenience. There were benches for navigating through the hatch of the capsule, an elevator at the launchpad, and a patient transfer board to help Benthaus safely move from the door of the capsule and into her seat. There was also a leg strap that allowed Benthaus to move about in weightlessness so she could fully absorb the ‘breathtaking’ view of Earth.
3. Experiencing Space as a Parastronaut
The flight was suborbital and lasted for a little more than 11 minutes, reaching a height of about 105 kilometers. For Benthaus, there were moments of microgravity, which she later termed “the coolest experience ever.” Her flight marked a historic moment in space travel in that she was the first person living with paraplegia to travel into space.
4. ESA Parastronaut Feasibility
Benthaus’s accomplishment can be supplemented by the Parastronaut Feasibility Project by the European Space Agency, started in 2022. This project aims to enable astronauts with physical disabilities to participate in space flights. Indeed, the first parastronaut trainee in the agency, John McFall, is currently training to fly to the ISS, while various organizations, including the University of North Dakota, have found that people with disabilities can enter and exit space crafts as easily as those without disadvantages.
5. Medical and Physiological Considerations
An inclusive spaceflight must have methods of dealing with different medical issues. Disabled astronauts may have difficulty managing their medications by machines in space, can have an increased possibility of infections, or may need specialized physical exercise plans to combat reduced muscular and bone strength caused by microgravity. Some disabilities can have even positive effects on astronauts. People with lower-limb amputations, for instance, would not suffer from reduced muscular strength in their legs due to life in space environments.
6. Tech Innovations for Accessibility
With adapted seating systems and personalized restraints, technology readiness plays an essential role in making missions more inclusive for all astronauts. Spacesuits may also involve adapted entry points or improved mobility, and spacecraft can incorporate functional railings, modulated design, and specialized tools for easy accessibility and use. Such technological advancements can also provide comfort and security for all astronauts.
7. Implications for Future Spaceflight Standards
Benthaus’s flight highlights how the design of spacecraft and mission strategies needs to include considerations of inclusivity from inception. With extended missions being planned for both the Moon and Mars, the possibility of unintended disabilities—injuries incurred during a mission—renders accessibility a collective issue of safety for an entire team of astronauts.
8. Commercial Spaceflight’s Expanding Accessibility Role
Spaceflight in Blue Origin has taken passengers with blindness, hearing impairments, differing limbs, and mobility restrictions to space before. The success of the NS-37 further supports the push for the private sector to lead the charge toward accessibility, to supplement the initiatives already undertaken by government agencies, including the ESA, and their accessibility initiative. According to Phil Joyce, senior vice president for New Shepard, their goal is to expand their vehicles and reach a weekly cadence soon. Benthaus’ accomplishment goes beyond being an individual success. It is, in fact, proof of concept for human space travel accessibility. It is through the use of innovation and planning, and with Benthaus’ dedication to accessibility, that this spaceflight has broadened who can be considered an astronaut and opened up a new outlook for mankind in space.
