Fly Over Mars... in a Robotic Balloon

Posted by michael on Wednesday February 11, 2004 @05:28PM from the rather-large-balloon-needed dept.

Roland Piquepaille writes "A Californian company, Global Aerospace Corporation (GAR), is developing remote-controlled balloons for the NASA Institute for Advanced Concepts (NIAC). BBC News Online reports that their goal is to send these balloons carrying robots and cameras to explore Mars skies. But it's not for a near term future. The robotic StratoSail will have a stabilizing wing suspended several miles below it. It will be able to stay above Mars for months. It will send robotic probes to monitor the surface and minilabs to carry out experiments. This overview contains more details, references and images about the StratoSail."

Yeah, and this is actually an old idea that was used extensively by the Soviets during their push for planetary exploration. Since the atmosphere of Venus was so hot and dense, they were able to float the balloons with extremely heavy loads. The scheme worked well during the Venusian "night," until the sun came and expanded the volume of gas in the balloon, bursting it. The idea for balloons on Mars has been "floated" before, but it looks like it just might happen this time...
