NASA is investing in a fleet of robotic probes that could soon explore Jupiter, Saturn and other interstellar bodies made of gas by flying with momentum from the wind. NASA's Jet Propulsion Laboratory has been awarded $100,000 to complete a study that will explore the possibility of "windbots" buzzing through the atmospheres above Jupiter and Saturn. To work, each drone would need to be self-sufficient and able to recharge based on wind and changes in temperature. The news was first reported Thursday by Wired magazine. "One could imagine a network of windbots existing for quite a long time on Jupiter or Saturn, sending information about ever-changing weather patterns," Jet Propulsion Laboratory engineer Adrian Stoica told Wired.
