NASA's famous space telescope was carried by shuttle into Earth's orbit 20 years ago. Within weeks of that launch, it was discovered that this huge and hugely expensive bastard had a flawed optical system. Hubble was a real lemon.
Toni Myers' new IMAX doc about the Hubble is a first-person snapshot of 2009's final rescue mission, in which seven astronauts risked their necks to manually fix the telescope, making it the most dangerous job in tech-support history. Even at 43 minutes, with earnest but marketable narration by Leonardo DiCaprio and one amusing zero-gravity taco-preparation scene, Hubble 3D's perilous endeavors are about as thrilling to watch as plumbers snaking a drain ... in spacesuits.
If you want an eye-popping cosmic epic, rent Star Trek. If you want interactivity, take the kids to the planetarium.
