Small BodiesStories, updates, insights, and original analysis from The Planetary Society.
Inside, underneath, backward, upside-down
From holes on Mars to a spun-around moon and a flipped reflection, space science involves looking at things from all different angles.
Super-size it
Europa Clipper is a big spacecraft with big solar panels, all so it can perform a big mission. The galaxy is big too, and a Planetary Society member painted it that way.
Wow! Boom! Ultra cool!
The “Wow!" signal has a new explanation, and an ultra-cool experiment advances quantum sensing in space. Plus, making an asteroid go “boom!” might work, depending on the circumstances.
Life in other worlds
New research suggests liquid water might be hiding under the surface of Mars. Could life be there too?
Seeing the unseeable
From X-ray imaging to slithering beneath Enceladus’ crust, space technology is always expanding what we can see for ourselves.
A big find on Mars
A big rover makes a big find on Mars. Little rovers have their place in exploration, too.
Serendipity, a super-Jupiter, and saving VIPER
This was a big week in space, from Curiosity stumbling upon sulfur crystals to an exoplanet discovery and a major advocacy effort.
A planetary smash-up
A comet collided with Jupiter 30 years ago, and the resulting images still inspire awe and wonder today.
Rockets rock!
Rockets are an integral part of spaceflight, and this week they get the attention and admiration they deserve.
Getting a good look at what’s out there
From taking hundreds of thousands of photos of Mars to scanning the skies for asteroids, humanity is keeping an eye on our cosmic neighborhood.
Making history, making waves, and making LEGO
The first-ever samples from the lunar farside are here on Earth, Titan’s seas are wavy, and you can make LEGO bricks from space dust to build lunar habitats.
Now you see me…
Where and when to spot the ISS, learn what asteroids are made of, and search for life in the Cosmos.
Space superlatives
From the largest and most active volcanoes in space to the exoplanet with the “best hair,” this week is all about superlatives.
Happy little accidents
Sometimes science happens by accident. Other times, it goes exactly to plan.
Old becomes new
A star will become visible in the night sky, and old data from Venus yield new discoveries.
Mars rovers, helicopters, and sunsets
This week brings updates on the next missions to rove — and maybe even fly — over the surface of Mars.
A certain flair for solar activity
The Sun was in the spotlight this week, with a huge solar storm and the biggest solar flare in over a decade.
Can you imagine?
From visionary technologies to unusual planetary views, this week’s Downlink will challenge your imagination.
Wow! But also, yikes!
Photos and news from space to inspire, amaze, and even scare you a little.
Volcanoes are so hot right now
From Mars to Io, volcanoes top the list of hottest things in space right now — both literally and figuratively.
