Columbus sets sail on a modern-day voyage of science and exploration as Atlantis clears the tower at 2:45:30pm EST February 7th. Two months late to fix problems with engine fuel sensors and beating an improbable 70% chance of bad weather, the 4.5 million pound shuttle rides twin columns of gold and three main engines that total 7.5 million pounds of thrust. STS-122 delivered Europe's $2 billion Columbus science laboratory module to the International Space Station, over 25 years after it was first conceived.
