Space.com says that the Mars rover Opportunity finally launched to the red planet. Seems that everything from threating storms to fishing boats to old cork to a dead battery have delayed the second of the two NASA Mars rovers from launching. The first rover was named "Spirit" and launched in June and the second one that launched last night was named "Opportunity." It's important to launch at this time while Mars is at its closest to the Earth. This second rover will likely arrive around January of next year, the last of the 4 vessels going to Mars right now (2 from NASA, 1 from ESA, 1 from Japan) all due to arrive late this year or early next year.
