“Our challenge is that we have to get investment up front,” says Lansdorp. “We estimate it will cost $6 billion to get the first two colonists to Mars, then $4 billion per pair thereafter. But the whole world will be watching. The revenue for the Olympic games was $1 billion per week - and this will be the first time humans actually leave the Earth.”


i really don't like the sound of that...whatever it might mean....

for a start off...nasa has been lying about 'landing on the moon' since the 60s....that was the first time that humans supposedly 'left the Earth'....but i suppose that the meaning here is 'for a very long time'....possibly 'forever'...rather like 'moving country'....
