Mars rock and roll
A Mars rock may hold answers in the search for life, and spacecraft might roll along its surface. Plus, meet the red planet’s Rolling Stones Rock.
Award-worthy and record-breaking
From photographers to science communicators, this week we celebrate some well-deserved wins. Plus, our Day of Action is set to be the biggest ever.
Don’t stare at the Sun (unless you’re SOHO)
The Solar and Heliospheric Observatory isn’t just a powerful tool for studying the Sun; it’s one of the best comet hunters in existence.
An exciting discovery on Mars
NASA’s Perseverance rover has identified a potential biosignature on Mars.
Are you ready for your close-up?
Close-ups of the Sun’s coronal loops and a tiny piece of Bennu can teach us a lot.
Rock, ice, and glass
The Solar System is full of rocky and icy bodies, but this particular galaxy is made of glass.
All space rocks great and small
From large comets to tiny meteorites and all the asteroids in between, it’s worth finding all sizes of space rocks.
Do rovers dream of electric sheep?
Rovers like Curiosity need their sleep. Meanwhile, dreams of interstellar travel are being pursued.
Eat, sleep, explore space, repeat
Astronauts may be living on the frontiers of human space exploration, but they still need to eat and sleep like the rest of us.
Worlds in swirls
New research expands our understanding and observations of how planets form. And, good news in the fight for NASA funding.
Spaceflight worth the fight
A flyby anniversary reminds us why missions of exploration are worth fighting for.
Space sodas
Coke and Pepsi battled it out in space, and an astronaut got to enjoy another kind of sprite.
MRO, OMG!
NASA’s longstanding Mars orbiter is in the spotlight this week, along with some of our youngest and most passionate advocates.
I spy with new eyes
Vera Rubin releases its first images, asteroid discovery kicks up a notch, and JWST may have discovered its first planet.
Volcanic inactivity
Most of the Solar System’s volcanoes are dead — but not all of them. NASA’s budget is still in trouble, but people are speaking up.
Peaks and troughs
The Sun’s activity is peaking, while NASA’s budget is facing historic lows.
A crisis we must rise to
NASA’s budget is officially in grave danger, but there are things you can do to help.
Growing and shrinking
Planets and moons change size all the time, whether by attracting mass, shrinking in volume, or spewing their insides out of volcanoes.
Taking the time to see the light
Long-exposure photography can help see dim, distant light sources. It can also show us familiar lights in totally new ways.
Leaving tracks on other worlds
Our rovers and astronauts leave tracks where they explore. But there’s always the possibility that those tracks — and even entire missions — could be erased.
