The UAE has announced a moon mission that will use an unusually small rover, with just four wheels and a weight of 10 kilograms (22 pounds).
The rover, which will be built in Dubai, is much smaller than the last rover successfully deployed on the moon; China's Yutu-2 has six wheels and weighs 140 kilograms (310 pounds).
By comparison, Curiosity, NASA's only currently active Mars rover, is bigger still -- weighing 899 kilograms (1,982 pounds), the size of a small SUV.
The UAE is trying to join an elite club of only three countries -- the US, Russia and China -- to successfully land a spacecraft on the lunar surface. In 2019, India's Chandrayaan-2 mission crash-landed on the moon. Here you can see its rover on a ramp moving into the main vehicle, before launch.
China's Yutu-2 is the only active lunar rover, but NASA is looking to add one of its own. The Volatiles Investigating Polar Exploration Rover, or VIPER, is a mobile robot that will roam around the moon's south pole looking for water ice.
VIPER, roughly the size of a golf cart, is being tested at NASA's Simulated Lunar Operations Lab in Ohio.
Star trackers helped position the Hope probe into orbit.
The Hope probe launched from Tanegashima Space Center in southwestern Japan. The UAE has not yet announced partners for the rocket or launch pad for its 2024 unmanned lunar mission.
