Katy Perry reached more than 100 kilometers of altitude during a Blue Origin missionwhich made it part of the First crew integrated only by women who crossed the line of karmthe limit that marks the beginning of space according to international standards.
During the flight, the artist lived four minutes of anxiety, which, although it was brief, could have physical and biological repercussions.
While floating in zero gravity, he heard the iconic song What Firm Worldin the midst of an environment in which the crew unbrusted the belts to experience the ungravation.
Upon returning to the mainland, Perry expressed his enthusiasm and deep emotions by declare that he felt “super -consistent with life”, in addition to describing his experience as a “surrender to the unknown.” As a symbolic gesture, he kissed the ground when he descended.
How do you affect health travel to space?
Changes in the cardiovascular system
During the launch, the occupants of the space vehicle face a strength between 3 and 6 gwhich means feeling that the body weighs several times more than usual.
That intense pressure It makes it difficult to breathe, oppress the thorax and temporarily reduce blood flow to the brain. He heart is forced to redouble efforts to pump blood Under these conditions, what in people without training can lead to blurred vision or even fainting. Although this episode is brief, its requirement resembles that facing military pilots in extreme maneuvers.
Immediate effects on the body
Once the microgravity has been reached, Liquids that normally concentrate at the bottom of the body move to the torso and head.
As a consequence, many passengers have a swollen facial appearance, nasal congestion and even alterations in the sense of taste.
In addition, the Internal ear system, responsible for balance, conflict with what the eyes perceive, which generates disorientation and nausea In the first moments of the flight. In trips as short as Perry’s, it is possible that the symptoms do not manifest in its entirety, but the body begins to react almost immediately.
Changes at the cellular level
According to studies carried out by NASA, even brief exhibitions to the space environment are sufficient to provoke genetic alterations in blood cells.
They were observed Modifications in the structure of red blood cells and an activation of defense mechanisms related to oxidative stress.
Research in suborbital flights reveal that these cellular responses can begin in a few minutes and tend to be reversed once it returns to Earth. Even so, the body retains a kind of “memory” of the extreme environment it has experienced.
Radiation exposure
Although the dose is limited, passengers who travel beyond the earth’s atmosphere, even for few minutes, remain exposed to cosmic radiation.
Although it is a reduced amount compared to orbital trips, any incursion beyond the natural shield that represents the atmosphere implies receiving a load of high -energy particles, something that could have cumulative effects if repeated frequently.
