NASA Proposes 20-20-20 Airship Challenge, Calls for High-tech Airships

NASA has now put forward a challenge that calls for designs of an airship that can fly at altitudes higher than the current 65,000-foot limit for weather balloons and for longer than the existing ones.

At present, no airship is able to maintain an altitude of 65,000 feet (20 km) for more than 8 hours whereas weather balloons can soar to that height but are difficult to control and vulnerable to winds.

Such airships could aid scientists in research on astronomy and climate change and even be more capable than weather balloons.

Meanwhile, scientists at NASA’s Jet Propulsion Lab in California think airships could aid them in research on astronomy and climate change and even be more capable than weather balloons.An airship could carry telescopes into the stratosphere to observe stars and other celestial bodies.

“You would be able to follow weather patterns, even get above a hurricane,” said Jason Rhodes, astrophysicist at NASA’s Jet Propulsion Lab in California, who leads the proposed challenge. He has also noted that “A satellite cannot do that because its orbit can’t be changed.”

Such airships will be designed to aid scientific research projects, Space.com reported. Scientists are also working on an airship that could survey the skies of Venus.

Airships could also provide valuable insight into weather patterns. The proposed challenge would include two tiers. The first tier would call for designs for an airship that can lift 44 pounds and remain at 65,000 feet for at least 20 hours. The second tier designs would need to be a little more complex.

Those airships would have to support 440 pounds at the same height but for at least 200 hours. The proposed 20-20-20 Airship Challenge would become part of NASA’s Centennial Challenges program that offers prizes to citizen-designed tech that solves research problems that are of interest to NASA. NASA will first measure public interest in the airship competition before officially launching it.
