Video: E-Rex Lunar Excavator Collects Regolith

Comments

The E-Rex rover collects simulated lunar soil during the Regolith Excavation Challenge. The vehicle dumped 75 kilograms into the container, half of what was required to qualify for a prize. It collected more soil before it got stuck and the 30-minute collection period ran out. The team will return to Little Rock, Arkansas without any prize money.
