Small BodiesStories, updates, insights, and original analysis from The Planetary Society.
The Planetary Society’s role in real space missions
Since 1980, The Planetary Society has been active in over 20 space exploration missions, from leading public outreach efforts to funding the development of instruments.
Tech funded by Planetary Society launches to the Moon next month
A spacecraft trying to land on the Moon will carry PlanetVac, the lunar dustbuster that could change how we explore other worlds.
Mars’ enduring role in the search for life
New discoveries underscore why we must keep exploring the red planet.
The Hera launch: What to expect
The European Space Agency (ESA) is preparing to launch a mission to study the aftermath of DART's impact on the asteroid moonlet Dimorphos.
Could Europa Clipper find life?
For a mission that doesn’t aim to find alien life, Europa Clipper may come surprisingly close.
Connecting ancient life to other worlds
Looking to the past to guide the search for life.
Earthlings as aliens
Looking at life on Earth from another perspective.
Extraterrestrial artifacts
Could the Solar System host traces of other intelligent life?
The Tianlin Space Telescope
China is in the early stages of planning a huge space observatory to help answer the matter of whether we are alone in the galaxy.
Why the “habitable zone” doesn’t always mean habitable
The habitable zone is a useful concept in astrobiology, but it can sometimes paint an over-simplified picture of planetary habitability.
Ramses: A new mission racing to land on asteroid Apophis
When a skyscraper-sized asteroid narrowly misses Earth in 2029, three spacecraft may be along for the ride.
What would happen if we nuked an asteroid?
Detonating a nuclear weapon on or near an asteroid is one of several options for defending the Earth from an impact. Here's what nuking an asteroid might actually do, and why it isn't always the best option.
Mars may host oceans’ worth of water deep underground
The tentative discovery hints at an habitat where life could potentially thrive.
Eureka? Scientists’ first hints of life on other planets may not be so obvious
Knowing that you've found signs of life beyond Earth may not be as clear-cut and simple as one might think.
NASA discovers Mars rock with ancient potential for life
A single 3.5 billion-year-old rock shows signs of all the conditions life needs to thrive.
Does Jupiter protect Earth from asteroids and comets?
Jupiter has often been thought to protect the inner Solar System from asteroids and comets, but new research has shown that the giant planet may actually increase the risk of an impact.
How soon will Starship fly?
One rocket could decide how soon humanity returns to the Moon — and maybe one day sets foot on Mars.
China targets its first planetary defense test mission
China’s first planetary defense test is taking shape. The ambitious mission will use a single launch to observe and impact a near-Earth asteroid.
What DART has taught us so far
NASA's DART mission showed that if we detect a dangerous asteroid headed toward Earth, knocking it off course with a spacecraft is a potential option.
