See China’s Lunar Rover Set Off Across the Far Side of the Moon
It has a long journey ahead.
Earlier this week, Chinese lunar probe Chang’e-4 made history by becoming the first spacecraft to ever land on the far side of the Moon — the less-studied, mountainous half that faces away from the Earth.
Yesterday, we were blessed with a number of new high-resolution images, courtesy of China’s National Space Administration, showing the more mysterious side of the Moon in all its glory. The pictures had to make their way through a special relay satellite called Queqiao since radio communication with the far side of the Moon is far more difficult.
Chang’e-4 launched on December 7 to explore the differences between the far, and near side of the Moon in terms of their mineral composition, and structure. It’s also carrying a tiny biosphere containing a number of Earth-based species including potato plants and fruit flies.
The Yutu 2
The pictures, taken by Chang’e-4’s on-board cameras, show the Yutu 2 rover— China revealed that name yesterday — rolling down tracks and leaving the Chang’e-4 lander behind.
The rover is situated in the floor of the 115 mile wide (186 kilometers) Von Kármán Crater near the Moon’s South Pole.
Yutu 2 is the successor of the original Yutu rover that landed on the near side of the Moon back in December 2013 as part of the Chang’e-3 mission. Since the Chang’e-4 and accompanying rover were meant to be backups for their predecessors, the designs are strikingly similar.
The image above shows Yutu 2’s specialized wheels, designed to survive the treacherous, yet low-gravity conditions on the Moon’s surface.
Dark Side of the Moon?
The term “Dark Side of the Moon” is a misnomer — the far side of the Moon receives quite a bit of light, just as much as its near side.
As Space.com points out, the lunar day cycle lasts a much longer 709 hours — roughly 30 days on Earth. That means it will be light for half of that time, roughly two weeks.
In fact, Chang’e-4 landed shortly after the sun rose on the far side, meaning it has roughly 14 Earth days of daylight ahead of it.
And we can’t wait to find out what the lander — and Yutu 2 — have in store for us.
