NEO (Near Earth Objects)
Asteroids, Comets, and Space Junk.

It is the opinion of many that the only way for any species to survive is to do the following:

  1. start evolving intelligence ASAP after the cosmic event that destroyed your predecessors (the dinosaurs in our case which were exterminated 66 million years ago)
     
  2. develop space-faring technology ASAP then put checks in place to prevent the next cosmic event from destroying you

While it is debatable how much progress we've made on point #1, we've made virtually no progress on point #2 (sure we've started to observe1 but we've only taken a few "baby steps" when it comes to flying in space2). For less than 10 million dollars a year, a formal world wide consortium3 of astronomers could be doing a better job of searching for asteroids and comets which will eventually destroy some of, or all, human culture if we do nothing. The loss of life notwithstanding, what price would you place on the loss of any of the following examples: the Kaaba, the Taj Mahal, the Parthenon, the Pantheon, the Leaning Tower of Pisa, the Sphinx, the Pyramids, or Stonehenge just to name a few?

Superscript Notes:

  1. CCD based automated observatories like MIT's LINEAR and others are cranking out good results
     
  2. The U.S. Space Shuttle Fleet was permanently retired in 2011. Americans last went to the moon in December 1972 and appear to be unwilling or unable to return.
     
  3. This can't be done by just one country. Bad weather has been known to stop viewing at LINEAR for 3-4 week periods in New Mexico. Also, asteroid viewing is only done at night which means that daylight portions of the sky can only be done by observatories on the other side of the Earth. We can't wait until the shifting seasons allow western observatories access to a different night sky because the asteroid positions change too rapidly.
     
  4. Funding from the Planetary Society Shoemaker NEO Grant enabled La Sagra Observatory in Spain to detect 2012 DA14

2013 Update

Near Earth Objects (comets and asteroids) are a clear and present danger to all human culture as well as Earth's current biosphere.
  1. If dinosaurs had developed technology then they could have protected themselves from the asteroid strike associated with Chicxulub Crater on the coast of Yucatan, Mexico.
  2. Humanity has developed the necessary technology but political-ideological pressures have neutered NASA's ability to proceed beyond primitive NEO detection.
  3. Developing and implementing planetary protection technology just may be an evolutionarily survival prerequisite (so Tea Party thinking will doom us all). Think of this as a protective immune system for the whole planet.

  5. Mark your calendars for February 15, 2013 when asteroid 2012 DA14 will pass under the orbit of Earth's geosynchronous satellites. While this rock is only 50 m (~150 ft) wide, remember that similarly sized rocks were responsible for:
    1. the 1908 Tunguska Event in Russia
    2. as well as Meteor Crater approximately 43 miles (69 km) east of Flagstaff, Arizona.
  6. Oops, on the morning of February 15, 2013 while we were waiting for the approach of 2012 DA14, an asteroid approximately 15 m in size became an air-bursting meteor in an event now known as 2013 Russian meteor event. More than 1,200 people were injured by shock waves to buildings.
  7. http://en.wikipedia.org/wiki/Spaceguard quote: Arthur C. Clarke coined the term in his novel Rendezvous with Rama where SPACEGUARD was the name of an early warning system created following a catastrophic asteroid impact.
