Here’s Why The New Horizons Spacecraft Won’t Be Stopping At Pluto

In less than five weeks , New Horizons will zip past the Pluto - Charon system in a brief but historic skirmish . Given the Brobdingnagian interest in Pluto , it ’s just to demand : Why wo n’t charge deviser let the investigation hang out a while ?

The simple cause is that New Horizons ca n’t make a period at the Pluto - Charon system . It ’s a restraint that has as much to do with engineering as it does with basic natural philosophy .

In social club to get New Horizons to Pluto in a sane amount of time ( in this casing 9.5 years ) , NASA had to get the investigation moving very , very fast . And a probe on the move can be difficult to slow down .

After its launch from Cape Canaveral on January 19 , 2006 , the probe accede into an escape flight feature a speed of 16.26 kilometers per second ( 58,536 klick / h ; 36,373 miles per hour ) , setting a new record for the high launching velocity of a human - made object flung from Earth . New Horizons ’s skirmish with Jupiter offer a subsequent gravitational assistance that increased its stop number by an additional 4 km / s ( 14,000 kilometer / h ; 9,000 mph ) . Once at the Pluto - Charon organisation , the ballistic capsule will pass through at a velocity of about 13.8 klick / sulfur comparative to the dwarf satellite ( 49,680 kilometre / h ; 30,800 miles per hour ) .

That ’s obviously a destiny of momentum . To get New Horizons into Pluto ’s orbit , missionary work deviser would have to reduce its upper by over 90 % , which would require more than 1,000 times the amount of fuel the investigation can impart . That ’s a technologically impracticable proposition . And so , the investigation will have no selection but to surge past Pluto , feverishly snapping pics and taking measurements before being flung outwards towards the Kuiper bang .

Which is a pretty orderly solace prize . The New Horizons mission will be far from over after its July 14 coming upon with Pluto .
