Think Mars

Another mission to the moon is a waste of time

On the spring morning in 1927 when Charles Lindbergh set off alone across the Atlantic Ocean,only a handful of explorer-adventurers were capable of even attempting the feat. Many had tried before Lindbergh’s successful flight,but all had failed and many lost their lives in the process. Most people then thought transatlantic travel was an impossible dream. But 40 years later,20,000 people a day were safely flying the same route that the “Lone Eagle” had voyaged. Transatlantic flight had become routine.

Forty years ago this week,Neil Armstrong,Mike Collins and I began our quarter-million-mile journey through the blackness of space to reach the moon.

Neil and I walked its dusty ancient soil,becoming the first humans to stand upon another world. Yet today,no nation — including our own — is capable of sending anyone beyond Earth’s orbit,much less deeper into space.

For the past four years,NASA has been on a path to resume lunar exploration with people,duplicating (in a more complicated fashion) what Neil,Mike and our colleagues did four decades ago. But this approach — called the “Vision for Space Exploration” — is not visionary; nor will it ultimately be successful in restoring American space leadership. Like its Apollo predecessor,this plan will prove to be a dead end littered with broken spacecraft,broken dreams and broken policies.

Instead,I propose a new Unified Space Vision. It wouldn’t require building new rockets from scratch,as current plans do,and it would make maximum use of the capabilities we have without breaking the bank. It is a reasonable and affordable plan — if we again think in visionary terms.

A race to the moon is a dead end. While the lunar surface can be used to develop advanced technologies,it is a poor location for homesteading. The moon is a lifeless,barren world,its stark desolation matched by its hostility to all living things. And replaying the glory days of Apollo will not advance the cause of American space leadership or inspire the support and enthusiasm of the public and the next generation of space explorers.

Now,I am not suggesting that America abandon the moon entirely,only that it forgo a moon-focused race. As the moon should be for all mankind,we should return there as part of an internationally led coalition. Using the landers and heavy-lift boosters developed by our partners,we could test on the moon the tools and equipment that we will need for our ultimate destination: homesteading Mars by way of its moons.


Robotic exploration of Mars has yielded tantalising clues about what was once a water-soaked planet. Deep beneath the soils of Mars may lie trapped frozen water,possibly with traces of still-extant primitive life forms. Climate change on a vast scale has reshaped Mars. With Earth in the throes of its own climate evolution,human outposts on Mars could be a virtual laboratory to study these vast planetary changes. And the best way to study Mars is with the two hands,eyes and ears of a geologist,first at a moon orbiting Mars and then on the red planet’s surface.

Mobilising the space programme to focus on a human colony on Mars while at the same time helping our international partners explore the moon on their own would galvanise public support for space exploration and provide a cause to inspire young students. Mars exploration would renew our space industry by opening up technology development to all players,not just the traditional big aerospace contractors. If we avoided the pitfall of aiming solely for the moon,we could be on Mars by the 60th anniversary year of our Apollo 11 flight.
