Europe Wants Ideas for Cave-Spelunking Moon Robots. Here’s How You Can Help!
ESA has released a call for proposals asking for creative ways to design a robotic mission that would explore these caves, which could be related to old underground lava tubes that dried up over the eons and collapsed. The campaign is available on ESA’s Open Space Innovation Platform and closes Oct. 31. 2019.
The missions have several scientific objectives associated with them, ESA explained. Future explorers would not only need to access, navigate and map the caves, but may use other resources. Some possible ideas include establishing communications between the cave and “the outside world,” ESA said, while others involve instruments that could take measurements of the environment of the cave.
“Mission concepts may be based on a single rover or a distributed system of satellite, robotic or rover systems that operate together,”
