NASA is designing a small rocket (artist’s impression) that will launch from Jezero Crater, bringing soil samples back to Earth.

If It Works, This Will Be the First Rocket Launched From Mars

NASA has spent decades sending probes to other planets. Now it’s trying to go the other way.

Warmer air could place a heavier demand on airsickness bags.

Air Turbulence Will Likely Get Worse as the Planet Warms

Buckle up, it’s getting hot out there.

This is the end, beautiful friend.

Cassini’s Last Moments, in Gory Detail

For NASA’s Saturn explorer, the end will come quickly.

Assembled and enhanced from three Voyager 1 negatives, this picture shows Jupiter’s swirling clouds and Great Red Spot.

To Dare the Realm of Jupiter

Fran Bagenal’s Excellent Year

Pluto last summer, Jupiter this summer. Where to next for this veteran planetary scientist?

Juno's engine will burn for 35 minutes to place it in orbit around Jupiter.

Juno’s Do-or-Die Moment: What to Watch For on July 4

Robert T. Bigelow has developed the inflatable Bigelow Expanded Activity Module, an aluminum habitation, to test in space. Pictured is a one-third scale model.

The Future of Construction in Space

Is the International Space Station the last aluminum spacecraft?

This is what a gecko-based robot would look like if it could use the gripping forces in its gecko toes to keep from floating away from the space station. The illustration is of a concept called LEMUR—Legged Excursion Mechanical Utility Rover.

Orbital Inspectors

If the space station gets smacked by a micrometeoroid, an array of devices can find—and fix—the damage.

The Atacama Large Millimeter/Submillimeter Array in Chile is tuned to see radiation emitted long ago when the first galaxies formed.

A new telescope will tell us how the first stars and galaxies were born

The Universe’s Baby Boom.

An artist places us on the surface of Gliese 876 d, a planet in or near the habitable zone around a red dwarf star.

Earth-Like Planets Could be Right Next Door

Astronomers estimate that billions of habitable planets are orbiting red dwarf stars. What would it be like to live there?

Fifty thousand years ago, the mile-wide Meteor Crater was formed when a meteorite 150 feet across smacked into Arizona. Is another like it headed our way?

These NASA Alums Want to Build A Spacecraft to Protect Earth, and You Can Help

The B612 Foundation hopes to neutralize the asteroid threat.

When the pictures started coming in, nervous anticipation turned to celebration.

Awaiting Curiosity’s Fate

As the rover rocketed down to the Martian surface, the team at JPL could only wait and hope.
