In the approaching decade, more people will go to space than ever before as human spaceflight enters a new era. NASA, the European Space Agency and other government agencies are working together develop manned missions beyond the Moon. At the identical time, these agencies are working with private corporations to use new technologies to lower the costs of space exploration.
Companies like SpaceX, Blue Origin and Sierra Space have developed vehicles with reusable amplifiers, automated flight systems and light-weight materials support these space missions. Some even have their very own ambitions to construct private space stations, lunar bases or mining operations in the approaching many years.
However, as these technologies and partnerships rapidly expand the supply of spaceflight, new challenges arise. First, maintaining the health and performance of the astronaut crew. My team researchers and educators on the University of Colorado and others around the globe want to solve this problem.

New medical challenges in space
NASA astronauts are some of essentially the most sensible and healthiest people in the world. In one study, astronauts undergo extensive medical and psychological tests disqualified 26% of candidates from the ultimate round. This rigorous inspection and testing process effectively reduces the chance of a medical incident occurring during a mission.
However, as spaceflight becomes more accessible, astronaut crews on business missions will likely make up the bulk of people traveling to space in the approaching years. Private missions will be short and will remain in close Earth orbit for the foreseeable future, but this will likely be done by private crews less training and more chronic health conditions than skilled astronauts currently living and dealing in space.
One sec experiments on the International Space Station have extensively studied the conventional physiological changes that occur in the human body in weightlessness, there is no data on the behavior of common chronic diseases, akin to diabetes and hypertension, in the space environment.

This industrial development also creates opportunities for long-duration missions to the Moon and Mars. Due to the length of the mission and the gap from Earth, professionally astronauts participating in these missions will experience long-term weightlessness leading to bone and muscle loss, communication delays ranging from a number of seconds to 40 minutes, and extreme isolation lasting months or years.
Crews must operate autonomously while being exposed to new threats, akin to lunar and Martian dust. Due to the fuel needed for these missions, resources will be limited to the bottom possible mass and volume.
As a result, mission planners will have to make difficult decisions in advance to determine what supplies are really needed, with limited or unavailable options for resupplying food, water, and medicine. For example, in space there could also be radiation and humidity contained in the spacecraft cause medicines to spoil faster and change into unavailable and even toxic to crew members.
The space station crew has already done this access to the flight surgeon at Mission Control to help manage health care in the identical way telehealth is used on Earth. However, crews on distant planets will have to perform medical care and procedures themselves.
In the event of a medical emergency, crews may not have the opportunity to evacuate to Earth. Unlike a space station, where medical evacuation to Earth can occur in lower than 24 hours, lunar evacuations could take weeks. Evacuation from Mars may not be possible for months and even years.
Put simply, the present approach to spaceflight medical care will not meet the needs of future business and skilled astronauts. Scientists will need to develop new technologies and novel training approaches to prepare future service providers to treat conditions in space.
Current aerospace medicine leaders are either experts in aerospace engineering or medicine, but rarely do experts have formal training or full knowledge of each fields. And these disciplines often cannot speak their very own language, neither literally nor figuratively.
Training the subsequent generations
To meet the changing demands of human spaceflight, educators and universities are looking to train specialists who understand each the restrictions of the human body and the restrictions of engineering design.
Some schools and hospitals, e.g University of Texas Medical Branch, conduct training programs for medical school graduates in the sector of aviation medicine. Others, akin to UCLA AND Massachusetts General Hospitalthey’ve specialized training programs in aerospace medicine, but these are currently geared toward fully trained emergency medicine physicians.
My team on the University of Colorado created a program that integrates human physiology and engineering principles to educate medical students to think like engineers.

This program goals to help students understand human health and performance in the spaceflight environment. He approaches these topics from engineering design and limits the prospect of finding solutions to the challenges astronauts will face.
One of our hottest classes is called Mars in simulated surface environments. In this class, students explore engineering and medical scenarios in a simulated Martian environment in the Utah desert. Students navigate the challenges of working and caring in a space suit and in a desolate, Mars-like landscape.
The stress of simulations will be real for students, they usually learn the way to use their combined skills to take care of other crew members.
Educational programs like these and others are designed to produce trained professionals who understand each patient care and the procedural nature of engineering design and may mix the 2, each for space tourists in orbit and as a pioneer to the surface of one other planets.
A new era of spaceflight is upon us, and these programs are already training experts to make space accessible and secure.
