Sounds like NASA is just seeing how much hype and excitement there would be for an earth 2.0, even though this planet is probably nothing like earth

Well it is in the Goldilocks zone. Who knows.

So are Venus and Mars, if they had a way to test the atmospheric composition then I might be more likely to buy into it..

Another person stated that they're probably looking for more funding from hype that this story created, not a bad effort on their part

You do know that the zone refers to earth. Not Mars or Venus.

The Goldilocks zone refers to a minimum and maximum distance from the parent star that liquid water can exist on a planet. The zone is different for each type of star.. So Venus and Mars would be capable of having liquid water if they had the correct atmospheres.

That's completely true. Except that it is coined after earth because earth is the perfect distance to sustain life. That is why the term refers to earths distance. It talks about distance, has nothing to do with atmosphere or other physical properties of the planet.

I will use 186,000 mps for easier math.

186,000 x 60(seconds) x 60(minutes) x 24(hours) x 365(days) x 1,400(years) = 8,211,974,400,000,000 (total miles to planet)

then

40,000(current craft speed) x 60(seconds) x 60(minutes) x 24(hours) x 365(days) = 350,400,00 (miles per year traveled by our current craft)

Then divide the bigger number by the smaller one. Would be how many years it would take.

28 million years to get there traveling at 40,000 mph.

Its pretty cool though.

Could be. I rounded light speed so if you used the actual speed id say it could be around there.

if venus had an atmosphere would still be to hot the oceans would most likely boil, mars yes

Venus does have an atmosphere, an incredibly dense one, here's an interesting article about past water on Venus from Time magazine..

yea mostly a sulphure dioxide atmosphere, i was implying even it had an atmosphere like earth i should have worded it better right now its 860+ degree farenheit so doubt could sustain water even with a much thinner atmosphere. interesting article though, my guess is if it really did have vast amounts of water, something could of greatly shifted the orbit a billion years ago or and caused a temperature increase to what it is today. who knows if those oceans remained life could of evolved there before us
