Historically, spaceflight has been reserved for the very healthy. Astronauts are selected for their ability to meet the highest physical and psychological standards to prepare them for any unknown challenges. However, with the advent of commercial spaceflight, average people can now fly for enjoyment. The aerospace medicine community has had very little information about what medical conditions or diseases should be considered particularly risky in the spaceflight environment, as most medical conditions have never been studied for risk in space — until now.
The aerospace medicine group at the University of Texas Medical Branch at Galveston recently studied how average people with common medical problems — high blood pressure, heart disease, diabetes, lung diseases like asthma or emphysema and back and neck injuries, surgeries or disorders — would be able to tolerate the stresses of commercial spaceflight.
Overall, they found that nearly everyone with well-controlled medical conditions who participated in this project tolerated simulated flight without problems. The study can be found in the journal Aviation, Space and Environmental Medicine.
"Physiological stresses of flight include increased acceleration forces, or 'G-forces,' during launch and re-entry, as well as the microgravity period," said lead author Dr. Rebecca Blue. "Our goal was to see how average people with common medical problems, who aren't necessarily as fit as a career astronaut, would be able to tolerate these stresses of an anticipated commercial spaceflight."
Some medical conditions are of particular interest within the commercial spaceflight industry, either because of the high rate of occurrence or because of the potential to cause sudden, serious medical events. The researchers studied how people with these common conditions performed when put through centrifuge simulations of spaceflight launch and re-entry.
The centrifuge allows researchers to mimic the acceleration of a rocket launch or of a spacecraft re-entering through the atmosphere. Astronauts regularly use centrifuges to train for their own spaceflights. The acceleration forces expected in a commercial spaceflight profile are tolerable, but can be uncomfortable, for healthy individuals.
The researchers wanted to see if they were equally tolerable for individuals with complex medical histories or whether there were certain conditions that would make it more difficult for them to handle the flight.
"This study further supports the belief that, despite significant chronic medical conditions, the dream of spaceflight is one that most people can achieve," said Blue.

This research was supported by the Federal Aviation Administration's Center of Excellence for Commercial Space Transportation, which has designated UTMB's aerospace medicine group as a leader in research for the commercial spaceflight industry. The goal of the UTMB group is to identify the knowledge gaps regarding commercial spaceflight and to address these gaps with research to allow for science-based decision-making within the field. The team also had support from the National Space Biomedical Research Institute to complete this work.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
