An increase in health risks to the human body, and changes to outer space travel conditions could lead to modifications on lengthy trips to the unknown.
According to National Geographic, a recently released report from the Institute of Medicine of the National Academies suggests NASA to decide how to regulate long missions to space rather than make a generic law for all travel no matter how short or long a journey might be.
NASA has future trips planned to space that it is already planning and raising money for. These include expeditions to the Lasso asteroid in 2021, and Mars in the 2030s decade National Geographic reported.
NASA is currently using one billion dollars each year to fund the costs of the administration's Orion Multi-Purpose Crew Vehicles for the trips because of the safety guidelines associated with the travels.
"NASA is an exploration agency, that is what it does, and it has to make hard, dangerous decisions," Jeffrey Kahn a person knowledgeable about bioethics at John Hopkins University told National Geographic."There is just tremendous uncertainty and unknowns, real unknowns, about this kind of space travel."
"One surprise was hearing how many ex-astronauts, if they were civilians, had trouble finding health care after they retired from NASA because of their risky behavior at an early age of being in space," Kahn told National Geographic.
Trips scheduled to the International Space Station that are anticipated to last more than the usual six months are also in the works. These grant unwanted danger to strong harmful energy known as radiation, and weight that lack heaviness or feels light National Geographic reported.
"The agency is committed to pushing the boundaries of human exploration," Joshua Buck, a NASA spokesperson said in a statement National Geographic reported.
"However, we also are committed to the highest safety standards for those choosing to embark upon these bold missions."
