Lunar Cube

Lunar Rover Moon Cube China Mysterious

A mysterious ‘moon cube’ discovered by a Chinese probe on the far side of the moon has taken over the internet. And it can take months for the rover to figure out what the odd looking object is actually.

A Chinese lunar probe captured an image of a cube-shaped object on the horizon about 80 meters (about 262 feet) from its location, state science publication Our Space said. The latest travel log of the rover as of December 3rd. The post has sparked all sorts of speculation and memes by what social media users are calling alien homes, outdoor toilets, and COVID-19 test stations.

The cube is most likely a rock, but travel records suggest that it would take two or three lunar days or two or three months on Earth for a rover to examine it closely.

The Yutu-2 or “Jade Rabbit-2” became the first rover to land on the far side of the moon (the hemisphere that faces away from Earth) in 2019. Like many other space rovers, they move very slowly under tight control. by scientists on Earth.

First, the rover spent more than half of its life dormant. The temperature on a lunar night lasting about 14 days on Earth Day can drop to -292 degrees Fahrenheit (-180 degrees Celsius), making it too cold for robots to operate. You should also take a “nap” if your device gets too hot.

A wheeled robot has a designed maximum speed of 200 meters per hour, or 5.6 centimeters per second, or 0.12 miles per hour. But in reality, it doesn’t just go straight at full speed. According to a travel log published by Our Space, engineers carefully calculated every step the rover takes.

They have to help the rover avoid the small craters all over the lunar surface, keep the slopes from slipping, and guide them to their ideal resting place before nightfall. The rover also needs to make occasional stops to conduct scientific research.

Space engineers refer to images of the lunar surface taken by satellite probes to map the probe’s long-term path, and use photos captured by the probe’s own camera to design the probe’s short-term movements.

According to Our Space travel log, engineers create 3D models from photos and take the rover’s next steps based on the geological features of a specific location and the robot’s communication and energy status.

Before the rover departs, it will first practice its movements on the computer. With every step, the engineer analyzes the data from the new location to make sure you’re heading in the right direction. This mechanism aims to protect the rover from accidents that could cause the rover to stop working.

The rover hasn’t traveled too far since arriving at the von Karman crater in the Antarctic-Eitken Basin in January 2019 due to complicated navigation procedures. According to Our Space, it covered 170 moves and a distance of 839 meters (2,752 feet).

In short, Yutu-2 moves very, very slowly but surely.

A rover equipped with an autonomous driving system can move faster. The Chinese Mars probe, Jurong, capable of identifying obstacles on its own, traveled 1,000 meters on Mars in 100 days (103 Earth days), the government said.

NASA’s Perseverance Mars rover’s enhanced automatic navigation system allows it to travel at 120 meters per hour. In comparison, the Opportunity Mars rover traveled 28 miles over its 14-year lifespan, or about 880 feet per month, on average.
