Exploring the subsurface of other planets could be the key to determining whether life has ever existed beyond Earth. High precision cheap price Professional OEM Custom saliva ejector tipAs other missions, including NASA’s InSight lander, have shown, drilling through the surfaces of planets like Mars is difficult — it’s a little too difficult to drill more than a few inches below the surface.
Recently, the Curiosity rover measured for the first time total organic carbon in Martian rocks, an essential component of life molecules. But that doesn’t prove that life ever existed on Mars, as carbon can also be produced from abiotic sources. High precision cheap price Professional OEM Custom saliva ejector tip
New research suggests that the best chance of finding evidence of past or present life on Mars requires going deep below its surface — at least 6.6 feet (2 meters) below. Mars’ extremely thin atmosphere means that the surface of the red planet is bombarded with high-energy radiation from space, which could rapidly degrade substances such as amino acids that provide fragile evidence of life.
These harsh surface conditions also present challenges for astronauts, which is one reason scientists think caves on other planets could be the key to future exploration. Huge cave systems on the Moon and Mars could serve as sanctuaries for future space travelers.
Caves may also contain resources like water, reveal more about a planet’s history, and be a haven for evidence of microbial life. On Earth, there are a variety of cave systems, many of which remain unexplored, that support diverse microbial communities. But caves are dangerous — and since we’ve never peered into a Martian cave, it’s hard to know what to expect. High precision cheap price Professional OEM Custom saliva ejector tip
Before humans landed on Mars and explored its subsurface, scientists thought of a robot designed to crawl and climb in alien caves.

The idea was born in 2018, when Marco Pavone, director of the Autonomous Systems Laboratory at Stanford University, and his students were brainstorming ideas for Martian cavers.
They knew the robot needed to be able to grab anchors so it could move without falling over—if it couldn’t find enough anchors, it wouldn’t go very far.
One of his students came up with the idea of a small robot with arms that stretched out like a tape measure and could use spider webs like Spider-Man to help him navigate the New York City skyline.
The robot concept is somewhere between the size of a basketball and an oven, and is covered with extendable cantilevers with barbed clips that can grab objects and grab or push off the steep rocky surfaces of Martian caves. It will be able to immobilize itself and crawl over long distances. High precision cheap price Professional OEM Custom saliva ejector tip
When the robot’s boom is not needed, they roll up to avoid it.
Pavon, also an associate professor of aerospace at Stanford University’s School of Engineering, and his students came up with the idea for a robot with an extendable boom.
They created a proposal for submission to NASA’s Innovative Advanced Concepts program, which funds visionary concepts in space robotics that could transform future missions.
The cave robot could also be used to explore lunar caves to see if astronauts could use it as a new tool.
Pavon said the cave robot concept received Phase 1 funding, and the team used it to conduct a round of research that proved the concept could work.
Now, the cave robot has secured its second phase of funding. The team will use the next two years to conduct 3D simulations.
The place to prototype the robot, develop strategies to help the robot avoid risks, and test the robot in a realistic mission environment could be a cave in New Mexico or California.
These tests will determine how the robot can be used for future exploration. High precision cheap price Professional OEM Custom saliva ejector tip
