Petrology is a field of science in which scientists study the compositions of rocks and minerals and interpret their geologic history. A common graph petrologists use is the “pyroxene quadrilateral.” These graphs, like photos of space, can reveal an understanding of the remotest parts of the solar system.

While we can measure properties of these upper layers using ground-based instruments, satellite-borne remote sensing instruments can give us a more frequent, global, and often higher spatial resolution perspective. And that is precisely what NASA’s Global-scale Observations of the Limb and Disk (GOLD) mission will deliver.

OSIRIS-REx launched on September 8, 2016. Now, a year later, it's returning to its home to get a second boost on to its destination, the asteroid Bennu. It'll test all its cameras on Earth and the Moon in the 10 days after the flyby.

Today is the 40th anniversary of the launch of Voyager 1. Four decades later, both spacecraft survive, still producing science, still working on their interstellar missions. On the occasion of the anniversary, we revisit Carl Sagan's reflections on the significance of the Voyager missions.

The upcoming solar eclipse isn’t just about watching the Moon block out the Sun. A suite of NASA-funded science experiments will to study the unseen effects of the eclipse on Earth's atmosphere.
