China's history-making Chang'e 4 mission has been spied by one of its robotic moon-studying brethren.

NASA's Lunar Reconnaissance Orbiter (LRO) recently caught a glinty glimpse of the Chang'e 4 lander, which on Jan. 2 became the first-ever spacecraft to make a soft touchdown on the moon's mysterious far side.

On Jan. 30, LRO rolled 70 degrees to the west as it approached Chang'e 4's landing site, the floor of the 115-mile-wide (186 kilometers) Von Kármán Crater. The maneuver brought the Chinese lander into view for LRO, though the mission's rover, named Yutu 2 ("Jade Rabbit 2"), escaped detection.

The sharp crater behind and to the left of the landing site is 12,800 feet (3,900 meters) wide and 1,970 feet (600 m) deep.

The Chang'e 4 lander-rover duo carry a variety of scientific instruments, which they're using to characterize the surface and near-subsurface of Von Kármán Crater. (Yutu 2 rolled down twin ramps from atop the lander a few days after touchdown.)

The mission could help scientists understand why the moon's near and far sides are so different from each other, Chinese officials have said. For example, dark volcanic plains known as maria cover most of the near side but are rare on the far side.


The Chang'e 4 lander also totes a biological experiment, which contains fruit-fly eggs and seeds of a few plants, including cotton. The cotton seeds sprouted, becoming the first non-human organisms ever to live on the lunar surface (not counting the microbes that hitched a ride with NASA’s Apollo astronauts). The little plants froze to death soon thereafter, however.

And in case you were wondering: The moon has a far side and a near side because it's "tidally locked" to Earth, meaning it always shows the same face to our planet. (That would be the near side.)

LRO has been circling the moon since 2009. The spacecraft's high-resolution imagery assists a wide variety of scientific studies and also aids planning for future robotic and human missions to Earth's nearest neighbor, NASA officials have said.
