Orbit each planet. Land a probe on each planet. Land a probe on each moon. Bring back samples from each location. Colonize.
Until we do all those, we are cavemen with delusions of grandeur.
At least we have really nice caves these days.
Oil tankers tend to go forward a long while even after the engine is off.
MS has been going forward quite a while now without any engine running. And restarting it means that you have to invest a LOT of fuel just to get it going again, unless you strip that tanker down to a speedboat and leave the rusted hulk behind.
Can you rephrase this as a car analogy. I'm not familiar with nautical terminology.
Think in 3D, not 2D. This article appears to reference a decent study http://www.bbc.co.uk/news/science-environment-21692423 According to it, the average depth of ice in the Antarctic is around 2126m, (~6975ft, or ~1.3 miles!) At that depth, it would take the ice contained under a 1 square yard area to cover a football field with over a foot of ice. (6875*3*3 = 62275 cubic ft, 360*160*1=57600 cubic feet)
Oh yeah: that 2.1km average: it's apparently over a 12.295 million square kilometer area. 26.54 million cubic _kilometers_ of ice. while we're at it: surface area of the planet: 510,072,000 sq km (wikipedia).
So. simple math from there: 26,540,000/510,072,000 = 0.052km... or about 52m (170ft) for the planet if all ice in Antarctica melts. The article actually says potential equivalent of 58m, so an exercise to the reader to determine where the extra 6m comes from.. and how many cities that would affect.
BTW: Highly recommend seeing the movie Chasing Ice http://www.chasingice.com/ for a view of how fast the glaciers are changing. Netflix carries it.
Your not thinking fourth dimensionally!
