Kids eating at Carl’s Jr. and Hardee’s fast food restaurants will now find collectible space-theme toys when they open their combo meals. The promotion, which begins today and runs through February 24, is part of a collaboration between NASA and the chains’ parent company, CKE Restaurants, Inc. Four different toys will be offered: a pullback Mars rover, a Cassini probe that “orbits” Saturn, a “Cool Comet Mission” flywheel spinner and a Space Shuttle-themed, double-sided puzzle. Each toy also includes a “collector card” that shares facts about planets, NASA’s missions, spacecraft and discoveries.
