Balloon to Soar Over Martian Atmosphere

Engineers have demonstrated a new technology that could take flight high over Mars in future years. The work may lead to a platoon of balloons drifting through the thin Martian atmosphere. They would relay back to Earth outstanding aerial views of a variety of Red Planet wonders. By taking to the air via a Martian balloon, supporters of the work see a way to out-distance the slow crawl of ground-bound Martian rovers.
