At the frontier of our solar system!

NASA's spacecraft, New Horizons, which has travelled 5 billion kms in 9 years, is all set to show us Pluto for the first time. The closest distance the craft will get to Pluto is 12,500 kms at 1719h (or 5.19 PM which is incidentally, my roll number at school and hence the thrill, at the strange co-incidence!) tomorrow, 14 Jul.

A few more vital statistics of the New Horizons:-

     (a) 19 Jan 2006                              Launched on board an Atlas V rocket from Cape Canaveral.
     (b) Highest speed reached             58,536 km/hr
     (c) Weight                                     478 kg
     (d) Why the interest in Pluto?

            (i) In 2006, Pluto was denoted to a minor/dwarf planet because it lacks a clear orbital path
                 free of other objects, in fact, it crosses Neptune's orbit at times!
           (ii) Is one of the largest objects in the Kuiper Belt, a vast area of the outer solar system
                 where icy objects circle the sun.
          (iii) There's no form of life on it as it's cold and dark with temperatures at -223 degrees Celsius.
                 A lot of the surface is reddish brown as it's covered in complex chemical compounds
                 called 'Tholins'.
          (iv) It's important for understanding our solar system and the information collected will offer
                a few more pieces in the puzzle as to how mankind ended up living on the Earth!

      (e) Time needed for two-way communication between New Horizons and Earth is 9 hrs.
      (f) After flying past Pluto, the New Horizons will go to the Kuiper Belt.
      (g) Pluto, incidentally, has 5 moons.
      (h) And the planet takes 248 years to go round the Sun once.

The trajectory of the New Horizons, after lift off, with respect to the occasions it crossed the orbits of the planets enroute:-

      (a) Mars                           07 Mar '06.
      (b) Jupiter                        28 Feb  '07.
      (c) Saturn                         08 Jun  '08.
      (d) Uranus                        18 Jul   '11.
      (e) Neptune                      25 Aug '14.


Tailpiece.

What a long and lonely journey, huh?
