The European Space Agency’s Hera spacecraft launched on Oct. 7, 2024, from Cape Canaveral, Florida. It will travel to the Didymos-Dimorphos asteroid system to study the aftermath of the first-ever field test of an asteroid deflection technique.

This week we look forward to launches, gaze at glowing auroras, and get creative with glitter.

Europa Clipper will soon head for Jupiter's icy, potentially habitable moon. Without the advocacy efforts of The Planetary Society and our members, the mission may never have been possible.

The European Space Agency (ESA) is preparing to launch a mission to study the aftermath of DART's impact on the asteroid moonlet Dimorphos.

For a mission that doesn’t aim to find alien life, Europa Clipper may come surprisingly close.

Cameras on spacecraft are our eyes into the Cosmos. Sometimes they teach us things, sometimes they reveal gaps in our knowledge.

Weeks before the new fiscal year, Congress still hasn't finalized NASA's 2025 budget.

NASA is preparing to launch its flagship mission to explore Jupiter’s moon Europa. Launching as early as Oct. 10, 2024, and arriving in 2030, the mission will explore the icy world with a subsurface ocean that scientists think could have conditions favorable to life.

Life thrives on Earth, and we even send evidence of our presence out into the Solar System. Is anyone out there looking for us?
