Eclipses and Cosmic Purpose

Hundreds of moons, planets and other bodies in the Solar System, and  only ours — Earth and the Moon — have perfect solar eclipses.  Astronomers have long noted this strange phenomenon, and the unlikely parameters that cause it. Not only that, but they happen to occur in a time in Earth’s history where they can be observed.  Astronomer John Gribben writes:

Just now the Moon is about 400 times smaller than the Sun, but the Sun is 400 times farther away than the Moon, so that they look the same size on the sky. At the present moment of cosmic time, during an eclipse, the disc of the Moon almost exactly covers the disc of the Sun. In the past the Moon would have looked much bigger and would have completely obscured the Sun during eclipses; in the future, the Moon will look much smaller from Earth and a ring of sunlight will be visible even during an eclipse. Nobody has been able to think of a reason why intelligent beings capable of noticing this oddity should have evolved on Earth just at the time that the coincidence was there to be noticed. It worries me, but most people seem to accept it as just one of those things.

Even if we brush this off as coincidence, as some have tried to do, there is another layer to this. Many of the interconnected factors that allow the eclipse to occur, also allow life to exist on Earth. Continue reading

Last Man

When humans first entered the final frontier the very edge of technology was pushed to its limits. The race into space may have been driven by the Cold War, but ultimately there was something even greater behind it.

The human spirit.

That spirit has driven mankind to explore for millennia and space is no different. Every bit as dangerous as the New World, the Amazon and the Wild West, but this frontier has no bounds and is unforgiving. Unfortunately, the powers that be, quickly lost vision and returned to their myopia. In an age where technology is taken for granted, it is hard to believe this happened decades ago. It is also a reminder that we could do so much more than iPhones and smart cars.

There are some who still remain from that first wave; those who were there on the new frontier. This is the story of the last man to walk on another world:

A Pioneer Looks to Our Future

I’ve long been a supporter of space exploration. It is often one of the few bright spots in the world of government-funded programs. However, I have come to realize that it’s that same government that has crippled our ventures in the final frontier. Nearly every new president rolls out a new “vision” for NASA, often discarding whatever the previous leader had promoted. Funding is just potential “get votes” for visionless Congress and has largely been stagnate as they prefer to send money to other countries or bailout only the companies that support them. So space exploration moves along in fits and starts. I was pleased to see that Apollo 11 astronaut Buzz Aldrin largely shares these views in his new book Mission to Mars.

For decades, Buzz has championed our expansion in space and in this new book discusses how our government-run program has both succeeded and failed. He also sees the recent growth in private efforts in space travel as a new turning point on the frontier. This is indeed correct, and creating an environment where these efforts can continue to thrive and expand is critical. NASA has already begun relying on private industry to supply the International Space Station. Soon they will deliver astronauts and companies have begun using the facilities that once launched the shuttles. NASA has laid the groundwork, now the people must take over. If they do, space will no longer be the realm of the few.

Buzz details how NASA shouldn’t be tied up in returning people to the Moon. Certainly they should be involved in technology transfer, training, design and U.S. participation, but their main thrusts should be elsewhere. They went to the Moon 45 years ago. Time to trailblaze elsewhere. And that place is Mars.

The Apollo veteran outlines his cycler design which would put spacecraft in continuous flight between Mars and Earth. It’s an ingenious design that uses physics and reusable vehicles. Is it the only option? No, and he briefly mentions the Mars Direct plan that Robert Zubrin laid out years ago. It uses current technology and in-situ use of resources on Mars to drastically lower costs of a mission. It was the baseline for NASA plans for a time. Buzz’s plan has some overlap with Zubrin’s, though I think both can be used. Mars Direct is still the simplest way for early missions to reach Mars. Later, it could be used in tandem with cyclers to increase travel opportunities to Mars (and I’m sure technology will improve both methods, see Case for Mars for more on Mars Direct).

We also read on the potential of mining asteroids and the real need to detect and deflect ones that threaten Earth. Buzz’s plan to first land humans on the Martian moon Phobos before Mars seems an unnecessary detour, though the satellite does have potential for the outposts he describes. He implores that whomever is president in 2019 to use the 50th Anniversary of Apollo 11 to commit to a Mars mission. I think this would be another empty vision from our politicians who cannot see past another election cycle. There is no Cold War to drive the project. Just as the people are taking over spaceflight, travel beyond our world will be up to them as well (perhaps Mars One).

NASA will surely be a part of it and maybe enough forward-thinking people exist in our government to support it. They can justify it anyway they want to: Jobs, technology, education, exploration, resources. It would certainly be a huge step forward against all of our steps backwards.

In 1989, Buzz stood on stage as President George Bush put forth a plan to reach Mars in 2019. The poorly conceived plan went no where. Now we are talking about announcing a mission in 2019 that won’t even happen for many years after. That, to me, isn’t very visionary. We need to get past the government-style pushing off the future to some indeterminate time that often never arrives. Buzz asks, “America, do you still dream great dreams?”

Do you?

But What of Our Future?

Here we often discuss history, but what of our future? I wonder this as the shuttle program ends and after reading the The Case for Mars. The exploration of space is adrift, blown about by the shallow whims of politicians only interested in making it to the next election.

Will the lessons of history that tell us of the perils of short-sightedness ever impact the feeble minds of Washington?

Rome. China. The Middle East. All, often for centuries, turned their backs on the future for many regrettable reasons. Space travel held so much promise in the 1960s to turn people away from killing each other and enter into a prosperous adventure exploring a new frontier. Even though Apollo was largely born out of Cold War politics and launched on military technology, it was of such scale that it had Earth-changing potential.

Then it was ended.

Nixon canceled the last missions even though most of the hardware was already paid for or built. Then started decades of going nowhere, trapped in low-earth orbit. Nearly each president releasing a “vision” for the future then abandoning it. Plan after plan with no purpose other than to secure short-term votes only to have the next leader trash it. Note how they put goals so far out in the future that it would not matter if it failed or not. One of President Obama’s current “visions” is men visiting asteroids by 2025.

2025? This could be done by 2017. Asteroids are rich in mineral resources, yet as long as the government runs the show with their fake plans, we will never get there. The Moon has enough helium-3 to fuel the world for generations. Yet we still fight over gas and oil and hope for the best.

When will a politician come along with real vision? Not worried about making it to the next election? Someone who can explain why the final frontier is valuable and attainable? A person who pushes the government out of the way and lets the people take control?

Certainly the shuttle had its successes. It was an amazing vehicle that flew for three decades. It was also an engineering nightmare with too many compromises. Too much promised and too many eggs in one basket. The technical marvel, the International Space Station, is also an achievement. It also is underutilized and without direction. It almost became like, “Let’s get it finished, have it orbit a few years, then figure something out.” Its value as proving ground for private space efforts or Mars exploration is grossly unused.

Not that it is needed to go to Mars. The Case for Mars proved that. It also proved it doesn’t take decades or unimaginable amounts of money. NASA briefly pursued it and for a few short years began to embrace simpler, commonsense approaches to exploring Mars and the Moon. Then the superbrains of Washington intervened once again.

The government bailed out companies and banks that did everything wrong, but what of the space workers? The people who invested in our future? The people that did everything right and what was asked of them? The people who wanted to do so much more?

There are glimmers of hope as the private space industry finally emerges from underneath the crushing weight of the government and industry giants (i.e. SpaceX). But will someone in this election year actually stand up and provide a real vision? Not another fabricated feel-good plan that requires us to start from scratch again?

This isn’t new or hard. We did it over 30 years ago. Let’s leave our children something other than crushing debt and a legacy bereft of any forward-thinking.

Who will answer the challenge?
