SEO isn’t rocket science but neither is rocket science according to NASA

Okay not to beat a dead horse but let’s take a look at what NASA says about rocket science (they should know) and see if you can compare it to SEO. Here’s what NASA says about rocket science on their Rocket Science 101 site.  Looks pretty straight forward to me, thanks NASA.  

Assemble a rocket from main engine to payload fairing! Rocket Science 101 shows the basic parts of the launch vehicle, how they are configured, and how they work together to launch a NASA spacecraft.

Components for the Pegasus Series Launch Vehicle

  1. Payload Fairing
    • Fairing – The fairing is separated into two composite halves — with one half incorporating an integrated nose cap — and a separation system. The fairing protects the payload from the flow stream and also allows for the control of air quality, humidity and temperature around the encapsulated payload.
  2. Spacecraft
    • Spacecraft – The spacecraft is the NASA payload being launched. It is located inside the fairing with the avionics section and the Stage 3 motor.
  3. Booster
    • 3rd Stage
      • Avionics – The avionics section contains the flight computer, inertial navigation system, avionics batteries, telemetry system, and control electronics. This includes the gaseous nitrogen reaction control system, which helps control the vehicle attitude, especially right before payload separation.
      • HAPS – After burnout and separation from the Stage 3 motor, the Hydrazine Auxiliary Propulsion System (HAPS) hydrazine thrusters provide additional velocity, improved performance and precise orbit injection. When used, the HAPS is located inside the avionics section.
      • The Stage 3 Motor – The Stage 3 motor propels the vehicle to a height of 400 nautical miles and a velocity of 24,770 feet per second (approximately 22 times the speed the sound). These heights and velocities are dependent upon the weight and orbit requirements of the payload.
    • 2nd Stage
      • The Stage 2 Motor – The Stage 2 motor propels the vehicle to a height of 709,070 feet and a velocity of 17,809 feet per second (approximately 16 times the speed of sound). These heights and velocities are adjustable based on the payload’s weight and orbital insertion needs.
      • Interstage – This interstage serves as a connector between stages 1 and 2, and also provides an area for the nozzles and interstage electronics and components.
    • 1st Stage
      • The Stage 1 Motor – The Stage 1 motor propels the vehicle after drop from the Orbital Carrier Aircraft to a height of 207,140 feet and a velocity of 8,269 feet per second at burnout. The attitude of the vehicle is controlled by the Fin Actuator System. This stage has a fixed nozzle and a wing for additional lift.
      • The Wing – The wing is a delta wing design that provides lift during the stage 1 burn.
      • The Aft Skirt – The aft skirt protects the Stage 1 nozzle from aero heating and provides the structural attachment for the Fin Actuator System.
      • The Fins – The fins provide attitude control during the stage 1 burn.

So I guess the answer is no SEO isn’t rocket science but apparently neither is rocket science. Okay, I think I got it. I wonder if quantum physics is rocket science?



  1. At last some humour in the whole debate. Maybe its because I have a foot in both the PPC and SEO camps but I can’t really understand why the camps are so at odd. I would have thought both were slightly different techniques which can work together to achieve their aim, traffic.

    Some people take stuff to seriously good to see some people can have a laugh!

  2. So what is actually “rocket science” then? Brain surgery? 🙂

  3. Thanks Kelvin it was getting a bit too serious. I also do both and learn a lot from each camp.

    Actually Chris, Jeremy over at Search Engine Lowdown claims that seo is brain surgery so since seo is not rocket science and seo is brain surgery then brain surgery must not be rocket science either. Nice try though.
