That destination is an asteroid in an orbit between the Earth and Mars named Ryugu. Ryugu is designated “Type C,” meaning it is thought to have considerable amounts of water and organic materials, making it an exciting target for learning about the possibilities of extraterrestrial life and the history of this (and perhaps other) solar systems.

Years - Approach - Orbit - Asteroid - Summer

It launched in late 2014 and spent the next several years in a careful approach that would put it in a stable orbit above the asteroid; it finally arrived this summer. And this week it descended to within 55 meters (!) of the surface and dropped off two of four landers it brought with. Here’s what it looked like as it descended towards the asteroid:

These “MINERVA” landers (seen...
