Supercalifragilisticexpialadocious!

One of the longest words in the English dictionary which simply means 'super', which is what I have to say about the 'Rosetta mission to put a probe on the Comet 67 P/ Churyumov - Gerasimenko'!

Background.

This mission is all about finding our origins, our roots. Scientists are divided into two categories viz:-

     - one believes that comets and planets are made from the same clumps of dust and ice that spewed
       from our Sun's birth
     - the other believes that they are older than that and may contain grains of inter-stellar stuff older
       than our solar system.

The European Space Agency's Rosetta mission was, thus, conceived and the spacecraft was to be the first to put a probe on a comet. This has the support of the NASA by virtue of on board equipment to facilitate scientific studies.

Vital Statistics.

      - Lifted off from Korou in French Guyana on 02 Mar 2004
      - The lander that would separate from Rosetta and make the touchdown is named Philae
      - The comet is a combination of rocks, ice and dust particles and Philae will land on the 'rocky'
         head of the planet
      - The total distance that the spacecraft had to cover for the mission was 600 crore km and as of
         date, it's 51 crore kms from the earth
      - The time taken by the comet 67 P to go round the sun is 6.6 years and its diameter is 4 km
      - Rosetta has 11 on board scientific instruments and weighs three tons
      - Philae has 10 on board scientific instruments and weighs 100 kgs

And what happened today?

      - at 1405h Indian Standard Time, Philae had separated from Rosetta at a distance of 22.5 km
        from the comet 67 P
      - the speed of the comet is 55,000 kmph
      - was to soft land at a point, one km in circumference, named 'Agilkiya'
      - after landing, it was to be secured with ice screws and self deployed tethering harpoons

The present picture.

After almost ten hours of a series of maneuvers, the positioning of Philae at its predetermined spot
was still not completed as the harpoons had failed to deploy due to a glitch but efforts are on.


Tailpiece.

O God, please let the tethering harpoons deploy earliest! And wow, what a scientific expedition?
