Navigating the harsh terrain of other rocky worlds has consistently been challenging. The Free Spirit campaign unfortunately failed in its goal to will the plucky Martian rover out of the morass it found itself in, despite two years of continual effort from some of the world’s best engineers. To combat this difficulty, other engineers have turned to alternative propulsion methods, and a team of researchers in the EU have done just that for their work on an autonomous mining robot. They decided to use an Archimedes screw as their primary propulsion method.

Humans finally achieved controlled flight on another planet for the first time just a few years ago. Ingenuity, the helicopter NASA sent to Mars, performed that difficult task admirably. It is now taking a well-deserved rest until some intrepid human explorer someday comes by to pick it up and hopefully put it in a museum somewhere. But what if, instead of a quadcopter, NASA used a series of flexible-wing robots akin to bees to explore the Martian terrain? That was the idea behind the Marsbee proposal by Chang-Kwon Kang and his colleagues at the University of Alabama at Huntsville. The project was supported by a NASA Institute for Advanced Concepts (NIAC) grant back in 2018 – let’s see what they did with it.

Robotic companions are a mainstay of sci-fi series everywhere. From R2D2 to Johnny 5, these characters typically have a supporting role in the story and are helpful to their human companions. But what if they were integral to the humans in the story? So much so that they couldn’t live without their robotic compatriots? That’s the idea behind Biobot, which was given a NIAC grant in 2018 – why not use a robotic companion to carry supporting equipment on human extravehicular activities (EVAs) on other planets?

Utilizing regolith on the Moon or Mars, especially to refill propellant for rockets to get back off the surface, is a common theme in the more engineering-minded space exploration community. There have been plenty of proof-of-concept technologies that could move us toward that goal. One of the best supported was the Regolith Advanced Surface Systems Operations Robot (RASSOR). Let’s take a look at what made this project unique.
