Space Travel Mars and Beyond for Humans?

Space travel is a constant push, through NASA and several sources out there  a new problem has arise  for long duration in space.  The problem is not only engine propellant and cosmic radiation exposure but out of the 300 astronauts surveyed 30% reported gradual blurry vision after a two-week mission aboard the Space Shuttle.

Also 35% surveyed after six month shifts aboard the ISS (space station) reported the same short fall of vision effects of prolong weightlessness in space.  Once the astronaut returns to Earth the problem most often goes away but a study by the National Academies noted there had been “some lingering substantial effects on vision,” and that astronauts were “not always able to re-qualify for subsequent flights” at least not immediately.   Dr. Bruce Ehni, a neurosurgeon at the Baylor College of Medicine said “No one has been in space long enough to know how bad this papilledema can get,”  papilledema can lead to blindness if left unchecked, which is why Ehni said solving the issue was paramount for NASA.

“When NASA start going to long-distance destinations like Mars, you can’t end up having a bunch of blind astronauts.”

One astronaut reported that after three months aboard the ISS he could only see earth clearly through the bottom of  his prescription reading glasses. In the mean time NASA has flown special glasses to the space station produced by Superfocus that can help adjust this vision failure.  If that isn’t enough you have loss of bone mass because of the micro gravity, notice when the return of a mission or long duration the astronauts are carried from the capsule.

Then there is the exposure of cosmic radiation, you can feel this on Earth when your out in the daylight the intensity of the sun.  Now move yourself to the outer limits of our atmosphere and the exposure is much greater where to the point your space ship cannot shield you from such radiation it goes right through the ship.  The reason it’s not so intense on Earth is because of the magnet poles on the planet it forms a force field around the planet not allowing all radiation to penetrate.

Well now seems to me we are not going anywhere soon, humans need the environment we live in to exist. With that in order to survive the harsh environment of space we need gravity, shielding, oxygen, food, water, climate control, power and not to mention engine propellant along with time (what the speed of light?)  to get you there.  You know something this will be generation and many technology advancements before were going to explore the next planet and even terraform Mars.

Enjoy these next videos of our quest for space travel into the Heavens.  I might add, coming soon but not at a theater near you.

Interstellar travel will be much more difficult than interplanetary spaceflight; the distances between the planets in the Solar System are less than 30 astronomical units (AU = 93 million miles) whereas the distances between stars are typically hundreds of thousands of AU, and usually expressed in light-years.
