The lunar rover lost a fender and they taped it back on with duct tape. That worked for a while, then they had to make a new fender with laminated maps and duct tape.
Why is a fender such a big deal? Without a fender, the astronauts would get dirty. So why is that a big deal?
- Dirt is dark, and dark absorbs sun light. A dirty astronaut may become a fried astronaut.
- Dirt scratches visors, making it hard to see.
- Dirt gets in parts like hinges and breaks them.
