Spacecraft OSIRIS-REx attempts to grab a piece of an asteroid to bring back to Earth so scientists can study it to learn about the planet's origins.

The New Horizons spacecraft attempts to fly by a mysterious object known as Arrokoth, believed to be a primordial building block of the solar system. Three years after taking the first spectacular photos of Pluto, New Horizons is four billion miles from Earth, trying to achieve the most distant flyby in NASA’s history. If successful, it will shed light on one of the least understood regions of our solar system: the Kuiper Belt.
