LEV-1 and LEV-2 They are the names of two small robots that made the Japanese SLIM moon landing mission a partial success. The SLIM space probe landed on the moon's surface on January 19, but ended up resting on the surface in the wrong direction, upside down. This prevented the probe's solar panels from properly aligning with the sun, rapidly depleting the spacecraft's batteries. But shortly before landing, they lost their balance 2 small robots By Salim. They can do whatever they want Complete the tasks with flying colors.

The smallest device we have run so far
Lunar Expedition Vehicle 1 (LEV-1) weighs 2.1 kilograms and is equipped with a metal base to help it Jump across the moon Could you. Its main task was to carry 90 grams Communication device test, which, among other things, established radio contact with LEV-2, but also directly with ground stations on Earth. According to the Japanese space agency JAXA, it is the smallest and lightest communication device ever that provides direct data communication over a distance 380,000 km Produced, produced. Here is a video clip documenting the reception of the signal on the ground:
Ball with camera
The LEV-2 is smaller and lighter than the LEV-1. the Spherical robots It was developed through cooperation between the Japan Aerospace Exploration Agency, Doshisha University, and toy manufacturer Takara Tomy. The latter is known for it Transformers game characters. The robot can separate its two spherical hemispheres and turn them into wheels that it can use to roll across the moon's surface. One Extendable camera He is responsible, among other things, for the image showing the SLIM space probe landing in the wrong direction. You can see how the robot moves in the following video from minute 35:00:
Listen for signs of life
LEV-1 and LEV-2 were SLIM after landing Completely independent for a few hoursUntil their power supply ran out. The LEV-1 has solar cells installed It can send signals in the future. Every day, the Japan Aerospace Exploration Agency hears new signs of life coming from the robot. However, the lunar night at the landing site will begin in early February. During this time, the little robot is subjected to a tough test at temperatures of up to minus 130 degrees Celsius.
