Getting to another planet is hard enough, but getting under its surface can be really tough. So the innovative engineering projects presented at ESA’s first Networking/Partnering Initiative Day included a novel drill system taking inspiration from the timber-boring wood wasp.
Apollo astronauts wielded rotary drills to penetrate beneath lunar terrain, but the close-packed regolith proved extremely resistant. Similarly future robotic landers will need to drill into planetary surfaces, but the total force available will be small, dictated by limited mass and power as well as low local gravity fields.
