The historic Atlantis Space Shuttle launch on July 8 will likely be derailed by weather, according to NASA.

Kathy Winters, the shuttle weather officer, said there is a tropical wave in the Caribbean that's likely to come to Florida with a lot of tropical moisture.  As such, Winters predicts 70 percent chance that the July 8 11:26 am space shuttle launch will be canceled.

The weather is expected to be more favorable in the following two days; on July 9, the chances of no-go are 60 percent.  On July 10th, it drops further to 40 percent.

Given all the preparations NASA made for the July 8th launch and the many people who planned to take a long trip to Florida to watch it, switching up the date may seem like a big hassle.

However, weather conditions are no joke for space shuttle launches.

In fact, two Columbia Space Shuttle launches delayed 6 times before they finally successfully lifting off on their seventh tries, according to Space.com. A delay of just one time, therefore, wouldn't be too out of the ordinary.

Moreover, the 1986 Challenger disaster was primarily caused by the faulty design in the O-rings sealing a joint on the right solid rocket booster.  However, low temperatures that morning exacerbated the flaw and the decision to go ahead with the launch may have proved fatal.

The July 8 (or whenever it's going to be) Atlantis Space Shuttle launch is expected to draw hundreds of thousands of spectators to southeastern Florida.  This historic occasion will mark the last laucnh ever for the Space Shuttle program.
