What is the most curious obstacle that prevents people from being able to live on the moon?

“@a_n_d_r_i_a_: What is the most curious obstacle that prevents people from being able to live on the #moon? #preguntalealaluna #askthemoon”

Depending on who asks there are different things that can be settled as curious, so here I’ll cite some of the curiosities of life on the Moon.

Well, between the necessary conditions that we need to live are atmosphere and liquid water, which the Moon lacks, although I suppose this is anything but curious.

It seems that probably these inconveniences could be solved because exploration probes have detected water (in solid state – ice- ) under the surface of the Moon. With electric energy (such as photovoltaic) electrolysis could be done, generating gases which we would be able to breathe in closed environments or from inside an astronaut suit. This way, we would need no air from the Earth.

A little problem that could cause some funny annoyance is that gravity is lower than on Earth. This means that your weight is reduced, but when you try to accelerate your body, as your mass is the same you have the as inertia as on Earth and so it would take the same work to accelerate it on the Moon. As a consequence, the record in jumping would be really higher but not the one in distance running.

Another little problem we find is not on the Moon but in the trip. The lack of gravity makes everybody sick because our corporal fluids are decompensated and orientation and balance senses are imprecise. Astronauts are trained feeling dizzy while performing any activity because they are expected to do it in semi-dizzy conditions.

Since we are born, our liquid management systems adapt to Earth’s gravity. For example, our heart adapts to compensate the growing pressure difference between head and feet due to growth. The fact that our body is based in sometimes frail equilibrium causes a difficulty in maintaining the full functionality when facing gravity variations.

 

¿Cuál es el obstáculo más curioso que impide que vivamos en la Luna?

Partiendo de que hay cosas que pueden resultar más o menos curiosas según la persona te voy a citar algunas curiosidades de la vida en la luna:

Bueno, entre las molestias que todos conocemos y que supongo que tienen poco de curiosas está la falta de atmósfera y de agua líquida.

Parece que estas cuestiones serían resolubles porque las sondas de exploración han detectado suficientes cantidades de agua bajo la superficie en forma de hielo; así que con energía eléctrica (por ejemplo fotovoltaica) se podría hacer electrólisis y generar gases para respirar en entornos cerrados o dentro de escafandras. Sin necesidad de llevarnos el ‘aire’ de la tierra.

Un pequeño problema que puede dar molestias graciosas es que, aunque la gravedad es menor, eso solamente significa que tu peso es menor; sin embargo, cuando intentes acelerar tu cuerpo, tu masa sigue siendo la misma, es decir que tienes la misma inercia por lo que el trabajo para acelerarla es el mismo que en la tierra. Es decir, que en la Luna el record de salto de altura sería mucho mayor, pero el de los 100 metros no.

Otro pequeño problema no está en la propia luna, sino en el viaje; la ausencia de gravedad genera mareos a todo el mundo; nuestros líquidos corporales se descompensan y el sentido de la orientación y el equilibrio funciona sin precisión. A los astronautas los entrenan mareándolos antes de hacer una operación porque dan por sentado que es bastante probable que la tengan que realizar en condiciones de semi-mareo.

Desde que nacemos todos nuestros sistemas de gestión de líquidos se van adaptando a la gravedad terrestre; por ejemplo, el corazón para ir compensando la cada vez mayor diferencia de presión entre los pies y la cabeza, debida al crecimiento. Pues eso es un problema fundamental para mantenerse con plena funcionalidad cuando las condiciones gravitatorias varían, porque nuestro cuerpo se basa en ciertos equilibrios de líquidos, a veces delicados.
