Colonizing Space – Does it Make Sense?

Colonizing Space – Does it Make Sense?
Imaginary Lunar Colony Base

“Why We’ll Never Live In Space” by Sarah Scoles is the lead article in the October 2023 issue of Scientific American. This question is relevant with NASA proposing plans to establish colonies on the Moon and Elon Musk claiming that SpaceX will colonize Mars. Scoles points out that Biosphere 2, where people entered to live for two years, revealed that an encapsulated environment didn’t produce enough oxygen, water, or food for the inhabitants. Later experiments ran into psychological and personal conflicts for those involved. There are similar experiments planned in the United States, Kenya, Israel, and Oman. Does colonizing space make sense?

The problems of trying to survive in space are enormous. Scoles points out that studies of astronauts after spending some time in space show significant physiological damage. Immune systems falter, muscles shrink, and bone loss is so great that it outpaces bone growth. Eye damage, called neuro-ocular syndrome, is associated with space flight.

Radiation from various sources is the biggest problem of being in space. The Sun sends out a variety of radiations, all of which damage human tissue. The radiation of galactic cosmic rays is very difficult to stop. Followup reports on Biosphere 2 show many human problems in a self-contained environment. Those problems are not only physical issues of providing essentials for life but also psychological, social, and even re-entry issues. Medical studies of astronauts in the space station show significant physical and genetic damage. However, these studies involve fewer problems than would be faced in outer space. Biosphere 2 was on Earth, and the International Space Station is in low Earth orbit, where there is still some radiation protection.

When God created Earth, He gave us a more unique place than most of us realize. Science fiction ignores many issues involved in colonizing space. Even if we could overcome all of the obstacles, doesn’t spending tax money to address the challenges on this planet make more sense than sending a few people to Mars? We still have much to learn about life on Earth, and we need to work together to improve the lives of people on this planet. The teachings of Christ give us tools that enable us to do that.

Do We Really Want to Move to Mars?

Do We Really Want to Move to Mars?

Mars is our closest neighboring planet at 33.9 million miles (54.6 million km), and it seems that various countries want to send people there. Several countries have launched successful missions to fly by, orbit, or land on the red planet, but none have yet sent people there. The list includes the United States, the Soviet Union, Japan, the United Kingdom, India, Russia, the United Arab Emirates, and China. As for human explorers, Elon Musk of SpaceX once expressed a desire to send people there in 2024—an overly ambitious objective. The UAE wants to establish a colony there in the next 100 years—a much more conservative goal. The question is, “Do we really want to move to Mars?”

Why does Earth seem to be designed for life while Mars is a rocky and barren place without an atmosphere? Scientists theorize that at one time, Mars had an atmosphere but then lost 99% of it. Why? Mars is smaller than Earth, so it has less gravity to hold onto the atmosphere, but that’s only part of the answer. One hypothesis is that solar wind (charged particles from the Sun) tore away the atmosphere. Then why didn’t Earth lose its atmosphere since we are even closer to the Sun? Earth’s magnetic field protected our planet. Why do we have a magnetic field? The movement of Earth’s molten iron core generates the magnetic field.

Many other factors make planet Earth ideal for life, and importantly, advanced life. So do we really want to move to Mars? The now-defunct Mars One project got tens of millions of dollars from thousands of people who signed up for a one-way trip to Mars to establish a human colony there. Elon Musk has indicated that he wants to get people to Mars just for the sake of getting there. He was quoted as saying, “Fundamentally, the future is vastly more exciting and interesting if we are a space-faring civilization and a multi-planet species…”

With all of this desire to leave the planet ideally designed for life, the question we should ask is, “Was Earth’s design merely chance happenstance, or was it part of a divine design?” I suggest that the many factors that make our planet just-right for human life indicate more than chance coincidence.

Optimum Martian Viewing

Optimum Martian Viewing
Recently there has been much talk about Mars in the media. NASA and private firms such as Elon Musk’s SpaceX are working on plans to send people to Mars and eventually build a colony there. For the past month, a planet-wide dust storm has blocked sunlight from reaching the planet’ surface and caused NASA’s solar-powered Opportunity rover to shut down. In addition, Mars is now in “opposition” to Earth and at its closest point to us since 2003. The current position of Mars gives us optimum Martian viewing.

When astronomers say that Mars is in perihelic opposition to Earth, that means the Sun, Earth, and Mars are in a line with Earth in the middle. That makes the apparent luminosity of Mars the brightest that it is at any time. Also, it means that Mars rises each night as the Sun sets and Mars sets each morning as the Sun rises. So Mars is visible in the sky all night long, and it is two times brighter than Jupiter, which usually outshines it. In addition to Mars, Saturn, Jupiter, and Venus are also visible at this time in an east-west arc across the sky after sunset. You can distinguish Mars by its red color, and it will continue to be bright through August for the optimum Martian viewing opportunity.

On July 26, NASA announced, “It’s the beginning of the end for the planet-encircling dust storm on Mars.” However, it may be weeks or even months before the Martian atmosphere clears enough for the Opportunity to have enough sunlight to recharge its batteries and return to life. NASA hopes that the batteries will recharge before Opportunity freezes to death. The average temperature on Mars is minus 80 degrees Fahrenheit (minus 60 Celsius). That is not very hospitable to machinery, or humans.

In addition to the previous factors, Mars will be at its closest point to Earth today, July 31, 2018. It will be only 35.8 million miles (57.6 million km) away from us. Mars is at its closest point about every two years. When Mars is on the other side of the Sun, it is about 250 million miles (401 million km) away. For that reason, any mission to Mars will have to be precisely timed to reach our neighboring planet in the shortest time, but it will still take months to make the journey.

With all of the challenges of reaching and perhaps colonizing Mars, the work goes on to achieve that goal. Some, such as Elon Musk, are suggesting “terraforming” Mars. That is, modifying the climate to make it hospitable to earthlings. That would require raising the climate temperature, thickening the thin atmosphere, and having a stable supply of liquid water, among other things. Elon Musk suggested a method of doing that which involves bombing the polar ice caps with explosives. It sounds like science fiction, and a new report from two leading scientists, Bruce Jakosky of NASA and Christopher Edwards of Northern Arizona University suggest that it is. Their study published in Nature Astronomy concludes that “with current technology, we just don’t see that there are any viable options” for terraforming Mars.

What we need to remember as we consider all of this, is that God has given us a planet that has all of the right conditions for us to live on and enjoy. He has already “terraformed” it for us, and we need to protect that gift and use it wisely. In the meantime, we can enjoy the optimum Martian viewing opportunity He provided for us to see the “red planet” right now.
