NASA’s California-based JPL lab, under a grant from the NASA Innovative Advanced Concepts program, has issued a public challenge to develop an obstacle avoidance sensor for a possible future Venus rover.
The 'Exploring Hell: Avoiding Obstacles on a Clockwork Rover' challenge is seeking the public's designs for a sensor that could be incorporated into the design concept.
Venus is an extreme world. With a surface temperature in excess of 462 degrees and a surface pressure 90 times that of Earth, Venus can turn lead into a puddle and crush a nuclear-powered submarine with ease.
While many missions have visited our sister planet, only about a dozen have made contact with the surface of Venus before quickly succumbing to the oppressive heat and pressure.
The last spacecraft to touch the planet's surface, the Soviet Vega 2, landed in 1985. Now, engineers and scientists at JPL are studying mission designs that can survive the hellish landscape.
Jonathan Sauder, a senior mechatronics engineer at JPL and principal investigator for the Automaton Rover for Extreme Environments (AREE) concept, said, "Earth and Venus are basically sibling planets, but Venus took a turn at one point and became inhospitable to life as we know it."
Exploring and studying different geologic units across the surface of Venus could help us understand the planet's evolution, and could contribute to a better understanding of Earth's climate.
Powered by wind, AREE is intended to spend months, not minutes, exploring the Venus landscape. AREE could collect valuable, long-term longitudinal scientific data.
"By getting on the ground and exploring Venus, we can understand what caused Earth and Venus to diverge on wildly different paths and can explore a foreign world right in our own backyard," Sauder added.
As the rover explores the planet, it must also detect obstacles in its path, such as rocks, crevices and steep terrain. And NASA is crowd-sourcing help for that sensor design.
The challenge's winning sensor will be incorporated into the rover concept and could potentially one day be the mechanism by which a rover detects and navigates around obstructions.
The difficulty of this challenge is in designing a sensor that does not rely on electronic systems. Current state-of-the-art electronics fail at just over 120 degrees and would easily succumb to the extreme Venus environment.
That is why NASA is turning to the global community of innovators and inventors for a solution.
"This is an exciting opportunity for the public to design a component that could one day end up on another celestial body. NASA recognises that good ideas can come from anywhere and that prize competitions are a great way to engage the public's interest and ingenuity and make space exploration possible for everyone," added Ryon Stewart, challenge co-ordinator for the NASA Tournament Lab at the agency's Johnson Space Centre in Houston.
Participants will have an opportunity to win a first-place prize of US$15,000; second place wins US$10,000; and third place, US$5,000.
JPL is working with the NASA Tournament Lab to execute the challenge on the HeroX crowd sourcing platform. Submissions will be accepted through 29 May 2020.
AREE is an early-stage research study funded by the NASA Innovative Advanced Concepts (NIAC) program within the agency's Space Technology Mission Directorate (STMD). NIAC is a visionary and far-reaching aerospace program, one that has the potential to create breakthrough technologies for possible future space missions; however, such early-stage technology developments may never become actual NASA missions.
NASA Tournament Lab is part of NASA's Prizes and Challenges program within STMD. The program supports the use of public competitions and crowd sourcing as tools to advance NASA R&D and other mission needs.
