After a few decades of relative calm, the US aims to rekindle the space program and aim for the red planet.

Barack Obama announced ambitious new space plans when he visited the Kennedy Space Center on April 15th.

His speech mentioned “a sequence of deep-space destinations” and “progressing step-by-step until we are able to reach Mars.” As I watched his speech, I couldn’t help but wonder if this will be the catalyst for a new age of space travel and human discovery, as happened on Earth five centuries ago.

There’s also the distinct possibility it will lead to the overturning of the current theory of everything, just as humanity slowly accepted the Earth was not flat half a millennium ago.

This week, news from space offered hope of finding life on planets orbiting dead stars; but also cast more doubt on finding life outside our solar system. It has also been discovered that some planets do not orbit their stars in the same rotational direction, which is the reverse of the dominant scientific theory.

The European Age

One thousand years ago, Europeans must have looked out at the Atlantic Ocean and wondered what lay beyond the horizon. Maybe they thought that God had created the world to keep some knowledge beyond humanity where nobody dared to venture.

Discovering a New World.

Then Christopher Columbus traveled towards the horizon, and beyond it, to start the European migration to the ‘New World.’ Columbus thought he had reached Asia, yet of course, we now know that he reached a whole new continent previously unknown to him.

Thousands of travelers now cross the sea and horizon by plane and boat every day. On clear nights, many people look up at the sky, marveling at the colours created by the sun rising or setting, and wonder what is really out there among the stars.

Just as we have mapped much of our planet today, our descendants will know our universe as we now know Earth, and look back at our limited knowledge in the same way we viewed world geographical knowledge in Columbus’s age. It is likely they will be able to experience space as we now travel around the Earth.

From Moon Landings to Hubble Images

While flying machines are still in relative infancy, telescopes have four times the history, as they were first invented in the early seventeenth century.

Four hundred years of innovation have seen them reach incredible power and intricacy; the pinnacle of the technology is the Hubble telescope that is circling the planet to bring amazingly clear images from galaxies and nebulas almost too far away for us to comprehend.

The only equivalent in Columbus’s days might have been the stories and images brought back to Europe by Marco Polo and other travelers to the Far East. As some of those fantastic stories were proven to be accurate, while others were mistaken identities or downright falsities, the same might be true of our current perceptions about the physics of the universe.

It is currently believed that the Cassini spacecraft has discovered liquid methane lakes on Saturn’s moon Titan, which if true, is the first surface water found anywhere else in the universe.

NASA also believes they have discovered forty planets outside our solar system, and within a decade, they hope to find one in a habitable zone: the right distance from the sun to retain water on its surface.

The Future Awaits

While we are starting to map the solar system as Columbus began charting the Americas, there had been a long history of sailing before those expeditionary voyages.

Just over forty years ago, the Apollo missions took the first humans to the moon.

While this was a momentous achievement, if space exploration takes us to the edge of our solar system, or even out into intergalactic space, the moon landings might one day seem more like one small step rather than a giant leap.

    About ten years ago, the plan was for a manned Mars mission in 2015. We’ve definitely got the plan and means to create the technology already, but where’s the will?

  • Marc Latham

    Thanks Turner.

    Stephen Hawking doesn’t think we should try and contact aliens, and uses Columbus reaching America as an example of the conflict that might result from a meeting:

    I wonder if we could live in peace with aliens?

    Telescopes found a star 300 times bigger than our sun, and double the previous biggest. Not known yet how it became so big:

    I know we need to start some time and go somewhere, but when we have such pressing and costly problems here on earth can we afford to go to Mars or anywhere else?  It is a very complex and ridiculously expensive undertaking which is hard to justify when there is still so much poverty and conflict on our own planet.  Are we the kinds of creatures that should be extending our influence beyond our home? 
    Is it wise to spend a huge fortune we cannot afford on the egotistical whimsies of a few?  Let us fix our world and establish peace before we leap on to the next stage in space exploration.  We will have plenty of time to do so once we have healed otherwise there is little point and certainly we do not have enough time anyway.   Priorities!!  First things first.
