This week’s Question: The Curiosity rover, NASA’s biggest extraterrestrial explorer, was launched toward Mars last week. The mobile laboratory, 10 feet long by 9 feet wide, will search for evidence that the planet was once hospitable to microbrial life. The device’s on-board instruments are designed to hunt for organic compounds.
What do you think? Will the rover reveal that Mars might once have been hospitable for microbial life — or might even still be conducive to life?
