On May 31st another large asteroid (1.7 mile wide) will pass by Earth, but no closer than 3.6 million miles, this time.
On February 15th 2013 a small (150 foot diameter) asteroid passed within 17,000 miles of Earth, closer than our geo-synchronous satellites... and while our attention was distracted by this asteroid another one came in undetected and slammed into the atmosphere above Chelyabinsk, Russia. This 30 foot diameter rock exploded before hitting the ground releasing the equivalent energy of 500,000 tons of TNT. The resulting shock wave broke windows and damaged buildings throught the Chelyabinsk area and injured about 1,000 people, mostly from broken glass.

Was this a wake-up call from the cosmos? Are we prepared to defend the Earth from these rogue rocks?

In 1908 a 130 foot diameter asteroid slammed into the Tunguska River region of Russia flattening 820 square miles of trees. That's about the size of San Francisco.
65 million years ago, theory has it, the dinosaurs and almost all life was wiped out by an 8 mile wide asteroid that slammed into what is now the Yucatan Peninsula.

Just how serious is global warming/climate change? Is it really an impending catastrophe?

The reason I ask is the general solution to climate change seems to be de-industrialization - tearing down the very industries needed to build rockets and space vehicles necessary to explore space, and set up a defense against rogue asteroids.

Damaging asteroids hit the Earth about every 1,200 years, on average. The Tunguska River and Chelyabinsk incidents were only about 100 years apart.
Humans have developed the ability to travel into space in just the last century. Could there be a reason for this?
Why not 3 centuries ago? Or 10 centuries ago? Could this be an evolutionary necessity, that is occurring at just the right time?

The very first liquid fueled rocket, invented by Dr Robert Goddard, was successfully tested on March 26th 1926. It ran on Texaco gasoline.
The Saturn-V rockets that carried our astronauts to the Moon used RP-1 rocket fuel - a highly refined version of JP-5 jet fuel.
Fossil fuel has been pivotal in the development of space science. Technology's latest rockets, the SpaceX Falcon-1 and Falcon-9, both use RP-1.

Should human technological and industrial evolution be stifled in the name of environmentalism? What other species has any chance at all of thwarting an asteriod strike? Gorillas? Chimpanzees?

Could we be saving Mother Earth from the equivalent of a stuffy nose only to leave her exposed to being shot by an assault rifle?

Food for thought.

I joined San Diegans Who Care About the Environment, and also am the organizer of a new San Diego meetup, Breakthrough Energy Pioneers.

Our "aerospace" and "defense" industries have long been a great drain on the public treasury of our nation, with little in the way of resulting benefit either to the productive economy of our nation or general social benefit, not to mention our national reputation. Both industries have long been complicit in developing clean revolutionary (ie: "breakthrough") energy and transportation technologies that have nonetheless been prevented from open distribution - though many of these were funded entirely by taxpayer funding - nonetheless used regularly in the highly-classified "Black Budget" sectors of our nation's sprawling "Military Industrial Complex" (including in NASA's activities, past many decades).

All these things amount to core violations of the founding principles of our nation; a nation with a government intended to express "The Will of the People," respecting Constitutional and Bill of Rights principles. Such principles are violated when our lucrative "aerospace" and "defense" sectors continue to gobble up the majority of our federal discretionary budget, while the public gets "The Mushroom Treatment" re: true activities, agendas and options; and no tangible result other than ongoing "negative blowback," from misguided expenditures and adventures.

Earth has survived five billion years without our beloved "defense industry" playing cosmic cowboy, requesting yet more open-ended taxpayer, to shoot down asteroids. Dwight Eisenhower warned us about all this nonsense regarding an out-of-control "Military Industrial Complex" taking over national budgets and policy. Maybe it's time we go back and re-read his speech.

If our "Defense" and "Aerospace" industries would like to do something genuinely honest, honorable, sensible and constructive for a change - something that helps the people of our nation and larger world - they can start by coughing up the clean revolutionary Energy and Transportation technologies which they've developed with taxpayer support, yet which remain locked-down from open circulation via Section 181 of the 1951 Invention Secrecy Act or private-sector black-shelving.

Know any "White Hat" types in the sectors just mentioned? Then, get them to join our Breakthrough Energy Pioneers meetup and put their shoulder to the wheel helping our agenda. Associated collaborative projects include the Breakthrough Energy Movement, New Energy Movement, PESWiki­,­ and Thrive­.
